Dear all,

For a number of objects, the MIB does not specify default values. To my
knowledge, it was the intention of the document to let the MTA vendor
choose and implement reasonable default values in these cases. As
proposed, I will try to suggest wording to add to the description text
to make this more clear.

- pktcSigDevStandardRingCadence

  "A default value MUST be provided, but it is left up to the
  implementation to choose a reasonable default."


- pktcSigDevRingSplashCadence

  "A default value MUST be provided, but it is left up to the
  implementation to choose a reasonable default."


- pktcSigDevToneTable

  "The MTA device MUST make sure that, after the provisioning cycle,
  the table is fully populated (i.e. for each possible index, an entry
  MUST be defined) using reasonable defaults for each row that was not
  defined by the provisioing information."


- pktcSigDevRingCadenceTable

  Do we also need default values for each of the 128 possible entries in
  the pktcSigDevRingCadenceTable?

  I would also like to note that there are already a few default values
  foreseen in ETSI TS 101 909-4, as per Table B.1:

  Table B.1: Ring cadence default values
  cr(x)| t1-ring | t2-idle | t3-ring | t4-idle | t5-ring | t6-idle
  -----+---------+---------+---------+---------+---------+---------
  0    | 1000    | 4000    | 1000    | 4000    | 1000    | 4000
  1    | 1000    | 500     | 1000    | 3500    | 1000    | 3500
  2    | 500     | 500     | 500     | 500     | 1000    | 3000
  3    | 500     | 500     | 1000    | 500     | 500     | 3000
  4    | 1000    | 500     | 500     | 4000    |         |
  5    |         |         |         |         |         |
  6    |         |         |         |         |         |
  7    |         |         |         |         |         |
  8    |         |         |         |         |         |   
  ...  |         |         |         |         |         |
  127  |         |         |         |         |         |
  
  Maybe we can express this as:

  "The MTA device is allowed to provide appropriate default values for
  each of the ring cadences."


Thanks,

David

Dear all,

To clarify upon the mapping from NCS signal to MIB object, and upon the
"US"/"international" objects, we suggest the following descriptions and
references to be added (or something along those lines):

- pktcSigDevRgCadence and pktcSigDevRsCadence

  DESCRIPTION
    "This object is used for non-ETSI systems only. ..."


- pktcSigPulseSignalTable

  DESCRIPTION
    "... This table only needs to be supported when the MTA device
    implements the NCS E-package. The signals defined in this table are
    triggered by the corresponding signals defined in the E-package."
  REFERENCE
     "TS 101 909-4 Specification"


- pktcSigDevRingCadenceTable

  For this object, I would also like to suggest different wording
  regarding the "LE SIGNAL message". Since the MTA does not directly
  communicate with a Local Exchange, the description might be changed as
  follows:

  DESCRIPTION
    "In V5.2, Cadence rings are defined by the telco governing body for
    each country. The MTA must be able to support various ranges of
    cadence patterns and cadence periods. The MTA will be able to
    support country specific provisioning of the cadence and idle
    period. There will be at most 3 on/off transitions per cadence
    period. Each cadence pattern will be assigned a unique value ranging
    from 1 to 128 (inclusive) corresponding to the value of x plus one,
    where x is the value sent in the cr(x) signal requested per the
    appropriate NCS message, and defined in the E-package. The MTA will
    derive the cadence periods from the ring cadence table entry as
    provisioned by the customer. Objects in this table do not persist
    across MTA reboots. This table only needs to be supported when the
    MTA device implements the NCS E-package."
  REFERENCE
     "TS 101 909-4 Specification"

- pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence

  DESCRIPTION
    "This object is used for ETSI systems only. ..."


- pktcSigDevToneTable

  The problem here is that some, but not all, tones will be specific to
  ETSI because the corresponding signal is (or will be) only defined in
  TS 101 909-4, and not in the PacketCable specifications. We may want
  to list these separately, e.g.
  
  "The following tones are used for ETSI systems only:
  alertingSignal(17), specialDial(18), specialInfo(19), release(20) and
  congestion(21). These tones are triggered by the corresponding NCS
  signals as defined in ETSI TS 101 909-4."

  Note for the editor: the final list may be different and/or have
  different OID's.
  
  A reference could also be added:
  
  REFERENCE
     "TS 101 909-4 Specification, PacketCable NCS specification"



Thanks,

David

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP over Cable Data Network Working Group of the IETF.

	Title		: Multimedia Terminal Adapter (MTA) Management Information 
			  Base for PacketCable and IPCablecom compliant devices
	Author(s)	: E. Nechamkin, J. Mule
	Filename	: draft-ietf-ipcdn-pktc-mtamib-03.txt
	Pages		: 49
	Date		: 2004-2-2
	
This memo defines a portion of the Management Information Base (MIB) 
for use with network management protocols in the Internet community. 
In particular, it defines a basic set of managed objects for SNMP-
based management of PacketCable and IPCablecom compliant Multimedia 
Terminal Adapter devices.

A URL for this Internet-Draft is:

In the body type:
	"FILE /internet-drafts/draft-ietf-ipcdn-pktc-mtamib-03.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

The following summarizes the proposed changes to pktcSigDevCodecTable based on the suggestion(s) from David and Eugene:

DELETE THE FOLLOWING:

	--
	-- The codec table (pktcSigDevCodecTable) defines all combinations
	-- of codecs supported by the Multimedia Terminal Adapter (MTA). 
	-- For example, an MTA may support the following codecs and maximum
	-- number of connections for each codec:
	--
	-- Codec Type     Maximum Number of Connections
	--     pcmu                      2
	--     g728                      1
	--
	-- or
	--
	--     pcmu                      1
	--     g728                      1
	--     g729E                     1
	--
	-- Based on this example, the entries in the codec table would be: 
	--
	-- pktcSigDevCodecComboIndex pktcSigDevCodecType pktcSigDevCodecMax
	--             1                      pcmu                2
	--             1                      g728                1
	--             2                      pcmu                1
	--             2                      g728                1
	--             2                      g729E               1
	--

ADD THE FOLLOWING:

	--
	-- The codec table (pktcSigDevCodecTable) defines all possible
	-- combinations of codecs supported for simultaneous operation by the
	-- Multimedia Terminal Adapter (MTA).
	-- 
	-- For example, an MTA with two endpoints may be designed with a
	-- particular DSP and memory architecture that allows it to support
	-- the following fixed combinations of codecs for simultaneous
	-- operation:
	--
   -- Codec Type     Maximum Number of Simultaneous Codec Instantiations
   --
   -- PCMA						    3
   -- 
   -- PCMA						    2
   -- PCMU						    1
   --
   -- PCMA						    1
   -- PCMU						    2
   --
   -- PCMU						    3
   --
   -- PCMA						    1
   -- G729						    1
   --
   -- G729						    2
   --
   -- 1 PCMU						    1
   -- 1 G729						    1
	--
	-- Based on this example, the entries in the codec table would be: 
	--
	-- pktcSigDevCodecComboIndex pktcSigDevCodecType pktcSigDevCodecMax
	--
	--            1                     pcma                3
   --            2                     pcma                2
   --            2                     pcmu                1
   --            3                     pcma                1
   --            3                     pcmu                2
   --            4                     pcmu                3
   --            5                     pcma                1
   --            5                     g729                1
   --            6                     g729                2
   --            7                     pcmu                1
   --            7                     g729                1

REPLACE THE pktcSigDevCodecTable DESCRIPTION WITH THE FOLLOWING:

	pktcSigDevCodecTable OBJECT-TYPE
	    SYNTAX      SEQUENCE OF PktcSigDevCodecEntry 
	    MAX-ACCESS  not-accessible 
	    STATUS      current 
	    DESCRIPTION 
	        " This table describes the MTA supported codec types. An MTA
	          MUST populate this table with all possible combinations of
	          codecs it supports for simultaneous operation. An operator
	          querying this table is able to determine all possible
	          codec combinations the MTA is capable of simultaneously
	          supporting."

In general, instead of having extensive ASN.1 comment lines, 
I prefer to see the extra information in DESCRIPTION clauses.
That is hwere it belongs (I think).

Thanks,
Bert

Hi, Jean and Andy,

  It seems to me that there are two things we need to address and add the=20
text in the description.

1. Pre-defined modulation profiles MAY read-only. Andy's proposal as below=
=20
looks good to me.

"In some implementations, pre-defined rows created at system initialization=
=20
time may
not be deleted".

2. Rows persistence. Jean's proposal as below looks good to me.

"Entries with a status column (docsIfCmtsModControl) of value
  'active' MUST be persist across reboots. Entries with a
  status column (docsIfCmtsModControl) of value 'notReady' and
  'notInService' may not persist after reboots since those
  entries were explicit made not be available for use by the
  managed device ('notInService') or the agent had not
  sufficient info anyway ('notReady')."

Thanks a lot !
Minnie

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP over Cable Data Network Working Group of the IETF.

	Title		: Event Notification Management Information Base for 
			  DOCSIS Compliant Cable Modems and Cable Modem 
			  Termination Systems
	Author(s)	: A. Ahmad
	Filename	: draft-ietf-ipcdn-docsisevent-mib-03.txt
	Pages		: 30
	Date		: 2004-2-3
	
This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines a basic set of managed objects for SNMP-
   based event notification management of DOCSIS compliant Cable Modems
   and Cable Modem Termination Systems. This MIB is defined as an
   extension to the DOCSIS Cable Device MIB, RFC 2669 [5].

   This memo specifies a MIB module in a manner that is compliant to the
   SMIv2.  The set of objects is consistent with the SNMP framework and
   existing SNMP standards.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-ipcdn-docsisevent-mib-03.txt

To remove yourself from the IETF Announcement list, send a message to

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-ipcdn-docsisevent-mib-03.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-ipcdn-docsisevent-mib-03.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

Yes, agree that a more reasonable range should be considered for the pktcSigPulseSignalDbLevel object. In looking at the meter pulse range for this object, the max value specified in 300 001 is for Sweden (-30 dBm). Motorola recommends setting the range of this object to (-350..0) to accommodate Sweden and to allow some margin for other international countries. This range is specified at the analog POTs interface (i.e., the a-b terminals).

> Independent of this, it might worth noting that the current range of the "pktcSigPulseSignalDbLevel" MIB Object (-250..152) is very large considering only one of the modes (meterPulse) uses it and the country specifications do not require it to be so high. We would recommend reducing this to a more reasonable range of (-250..0).

I am concerned about many of the proposed clarifications. I previously commented:

"Remember, in the international market there is a hybrid need. For example, some operators use the L package and require E package extensions."

Clearly, there are situations where an operator uses L package AND E package features. Making references to ETSI only or NA only in the object descriptions is not accurate, and I think misleading. It is important to allow operators the flexibility to use the 
objects from the MIB they deem necessary for their operations.

As an alternative, I would propose adding comments to the introductory section of the MIB to make it clear that the term L package refers to the core functionality (as defined by CableLabs/PacketCable) and the term E package refers to extensions over and above the core package (defined in support of international requirements). Further, all references to ETSI and NA in the MIB object descriptions could then be eliminated in a subsequent draft of the MIB, and replaced with L or E package comments as appropriate.

Yes agreed. The SYNTAX for pktcSigDevToneDbLevel has been changed to "TenthdBm".

Also, after further review, Motorola recommends the range of this object be changed to (-250..30). Per EN 300 001 the largest signal level for voice band tones is 0 dBm. Considering G.711 PCM coding allows amplitudes slightly above + 3 dBm, it would appear that the voice band tone maximum specification could be set to +3 dBm and meet the intent of the ETSI specification. This range (-250..30) is specified at the analog POTs interface (i.e., the a-b terminals).

But this is exactly what DEFVAL means.  RFC 2578 clause 7.9 says:

   The DEFVAL clause, which need not be present, defines an acceptable
   default value which may be used at the discretion of an agent when an
   object instance is created.  That is, the value is a "hint" to
   implementors.

Well, if you have the E-package, then you would also need the L-package.
Using the E-package alone, without also using the L-package, is not
possible.
Remember, the E-package, defined in appendix B.4 of TS 101 909-4, is an
extension to the L-package, that was defined out of a need to map V5 sign=
als
and events to NCS. For instance, there is no way to let an MTA play dial
tone using only the E-package; you need the "dl" signal from the L-packag=
e
for this.

My idea of the "ETSI systems" and "non-ETSI systems" terminology, was tha=
t
an operator that uses the L- and E-package would fall under the "ETSI
systems" category, and an operator using the L-package alone would fall
under the "non-ETSI systems" category.

I believe that this is the source of the confusion; you maybe interpreted=
 it
as if "ETSI systems" referred to E-package *only*?

In any case, it would indeed be beneficial to clarify on what "ETSI syste=
ms"
and "non-ETSI systems" mean in this context.

With this in mind, is my proposal not the same as yours, then?

Regards,

David

One thing I would like to recommend is to avoid using the phrase "may =
not", as its meaning can be somewhat ambiguous.

re: row persistency


Hi, Jean and Andy,

  It seems to me that there are two things we need to address and add =
the=20
text in the description.

1. Pre-defined modulation profiles MAY read-only. Andy's proposal as =
below=20
looks good to me.

"In some implementations, pre-defined rows created at system =
initialization=20
time may
not be deleted".

2. Rows persistence. Jean's proposal as below looks good to me.

"Entries with a status column (docsIfCmtsModControl) of value
  'active' MUST be persist across reboots. Entries with a
  status column (docsIfCmtsModControl) of value 'notReady' and
  'notInService' may not persist after reboots since those
  entries were explicit made not be available for use by the
  managed device ('notInService') or the agent had not
  sufficient info anyway ('notReady')."

Thanks a lot !
Minnie

After taking a quick look at 300 659, I note the lower bound for the T4 parameter for the pktcSigDevCIDFskAfterDTAS object is 45 ms not 50 ms.

Clearly, there is nothing broken regarding the MIB definition for these objects. In fact, the change proposed for pktcSigDevCIDFskAfterDTAS would cause an MTA to be unable to meet lower bound for the 300 659 timing specification noted above.

I recommend leaving the range for these objects as 0, as presently defined in the MIB and indicating that the object range meets or exceeds the ranges in the 300 659 specification. The later specification should be the definitive guide for any pass/fail test criteria.

My comments:
>- pktcSigDevStandardRingCadence, pktcSigDevRingSplashCadence
>"A default value MUST be provided, but it is left up to the implementation to choose a reasonable default." - 
It seems to me that having a requirement of this nature in the MIB is not meaningful. Also, I don't see how "reasonable" can be tested. An arbitrary value is not meaningful. Instead, how about "The default value for this object is as specified in the "L" package as defined in the PacketCable NCS specification".

>- pktcSigDevToneTable
>"The MTA device MUST make sure that, after the provisioning cycle, the table is fully populated (i.e. for each possible index, an entry MUST be defined) using reasonable defaults for each row that was not defined by the provisioning information."

This statement is not necessary. By utilizing the DEFVAL clause an initial value for each parameter associated with a row can be established. Unfortunately, I see the DEFVAL clause is missing in many of the table objects. Consequently, I would recommend a DEFVAL clause be added for the following objects:

pktcSigDevToneFirstFrequency    	DEFVAL { 0 }
pktcSigDevToneSecondFrequency 	DEFVAL { 0 }
pktcSigDevToneThirdFrequency	DEFVAL { 0 }
pktcSigDevToneFourthFrequency	DEFVAL { 0 }
pktcSigDevToneFirstToneOn		DEFVAL { 0 }
pktcSigDevToneFirstToneOff		DEFVAL { 0 }
pktcSigDevToneSecondToneOn	DEFVAL { 0 }
pktcSigDevToneSecondToneOff	DEFVAL { 0 }
pktcSigDevToneThirdToneOn		DEFVAL { 0 }
pktcSigDevToneThirdToneOff		DEFVAL { 0 }
pktcSigDevToneFourthToneOn	DEFVAL { 0 }
pktcSigDevToneFourthToneOff	DEFVAL { 0 }
pktcSigDevToneWholeToneRepeatCount	DEFVAL { 0 }
pktcSigDevToneSteady			DEFVAL { false } 

The DEFVAL approach would also minimize any operator configurations.
>- pktcSigDevRingCadenceTable
>"The MTA device is allowed to provide appropriate default values for each of the ring cadences." 
How about:

"The MTA is allowed to predefine the ring cadence for one or more rows in the pktcSigDevRingCadenceTable."

Motorola does not agree with the proposed change to a digital reference point.
In looking at the PC NCS spec, there is guidance that the RJ11 connector is the appropriate reference point. The MIB also supports RJ11 as the reference point:
"An endpoint or MTA endpoint is a standard RJ-11 telephony physical port located on the MTA and used for attaching the telephone device to the MTA."
In addition, the Telecommunications industry uses the RJ11 connector as the reference (interface) point. Newer standards also use this as the demarcation between the Network Operator and the CPE, thus it is the user "interface" reference. Changing to an internal reference point (digital PCM code) does not have meaning since it cannot be directly measured by the operator  when the MTA is installed.
Therefore, it is appropriate for the reference to be as presently stated in the pktcSigDevToneDbLevel object. The MIB, which is provisioned by the operator of the system must be "friendly" to the operators point of view. To burden the operator with tracking loss plans (which may vary from MTA to MTA or line to line) is not practical.

Well, about anything that is not plain silence could be considered
reasonable :-)

Fine with me. In that case however, I would make the default value
explicitly clear using a DEFVAL clause.

I agree with the DEFVAL clause approach, but don't we still need to make
sure that every row is present in the table?

Agreed.

We do not see anything particular attractive in number "45" or "50" =
except that it should be some value greater than "0" as the latter =
really does not make sense (one cannot expect the MTA to be able to deal =
with the 0-length interval between the ring and the beginning of the FSK =
signal). If  300 659 states that the lower bound is 45, why not to make =
it "45". If you are concerned about possiblity for the 300 659 to be =
modified with the lower than the number "45" value than, I think, a new =
value will still be reasonably greater than "0".

The bottom line - we feel comfortable with any value for the lower bound =
(say 45) which is in line with 300 659 and provided that this value is =
reasonable.

Eugene.

After taking a quick look at 300 659, I note the lower bound for the T4 =
parameter for the pktcSigDevCIDFskAfterDTAS object is 45 ms not 50 ms.

Clearly, there is nothing broken regarding the MIB definition for these =
objects. In fact, the change proposed for pktcSigDevCIDFskAfterDTAS =
would cause an MTA to be unable to meet lower bound for the 300 659 =
timing specification noted above.

I recommend leaving the range for these objects as 0, as presently =
defined in the MIB and indicating that the object range meets or exceeds =
the ranges in the 300 659 specification. The later specification should =
be the definitive guide for any pass/fail test criteria.

As NCS Spec does not have any specific reqs for L-package except for ref =

It seems to me that having a requirement of this nature in the MIB is =
not meaningful. Also, I don't see how "reasonable" can be tested. An =
arbitrary value is not meaningful. Instead, how about "The default value =
for this object is as specified in the "L" package as defined in the =
PacketCable NCS specification".

>- pktcSigDevToneTable
>"The MTA device MUST make sure that, after the provisioning cycle, the =
table is fully populated (i.e. for each possible index, an entry MUST be =
defined) using reasonable defaults for each row that was not defined by =
the provisioning information."

This statement is not necessary. By utilizing the DEFVAL clause an =
initial value for each parameter associated with a row can be =
established. Unfortunately, I see the DEFVAL clause is missing in many =
of the table objects. Consequently, I would recommend a DEFVAL clause be =
added for the following objects:

pktcSigDevToneFirstFrequency    	DEFVAL { 0 }
pktcSigDevToneSecondFrequency 	DEFVAL { 0 }
pktcSigDevToneThirdFrequency	DEFVAL { 0 }
pktcSigDevToneFourthFrequency	DEFVAL { 0 }
pktcSigDevToneFirstToneOn		DEFVAL { 0 }
pktcSigDevToneFirstToneOff		DEFVAL { 0 }
pktcSigDevToneSecondToneOn	DEFVAL { 0 }
pktcSigDevToneSecondToneOff	DEFVAL { 0 }
pktcSigDevToneThirdToneOn		DEFVAL { 0 }
pktcSigDevToneThirdToneOff		DEFVAL { 0 }
pktcSigDevToneFourthToneOn	DEFVAL { 0 }
pktcSigDevToneFourthToneOff	DEFVAL { 0 }
pktcSigDevToneWholeToneRepeatCount	DEFVAL { 0 }
pktcSigDevToneSteady			DEFVAL { false }=20

The DEFVAL approach would also minimize any operator configurations.
>- pktcSigDevRingCadenceTable
>"The MTA device is allowed to provide appropriate default values for =

How about:

"The MTA is allowed to predefine the ring cadence for one or more rows =
in the pktcSigDevRingCadenceTable."

The current definition of the ring cadence related objects such as =
pktcSigDevRingCadence, pktcSigDevStandardRingCadence, and =
pktcSigDevRingSplashCadence, does not accomodate the possiblity for the =
cadence sequence to be repeatable. This is also inconsistent with what =
currently exists in the PacketCable Signaling MIB. To compencate for =
this deficiency, the either of the following approaches is proposed for =
further discussion:

1. "Borrow" one bit (MSb) from the second byte to indicate the =
repeatable sequence. This will reduce the max time interval by 50msec, =
but will require just to slightly modify the description of the MIB =
objects.

2. Extend the SIZE range by one byte, indicating the repeatable tone =
sequence. This extra byte will immediately follow the first one (the =
length). In this case SIZE and desciptoins of all MIB objects should be =
modified.

That would imply that it is possible to configure, by MIB, the MTA to be
non-ETSI compliant. Is there a specific reason for this? For instance, do
you have knowledge of large numbers of rolled-out equipment (e.g. caller =
ID
devices) that are non-ETSI compliant, and thus require different timing
constraints? Or do you want a lower bound of zero to accomodate for futur=
e
changes in the ETSI specs?

> The
> later specification should be the definitive guide for any
> pass/fail test criteria.

The ETSI specs would indeed be the basis for the test criteria. For examp=
le,
for the pktcSigDevCIDRingAfterFSK value, the 300 659 spec says the minimu=
m
is 200 ms. Assuming that the range in the MIB allows for values outside t=
he
ETSI range, then how do we interpret this?
We feel that, for testing purposes, the MTA MUST implement at least the E=
TSI
range. Values outside the ETSI range, but inside the MIB range, would the=
n
have to return an SNMP "Commit failed" error on a SET for such a value. T=
his
would then be tested. Second, values outside of the MIB range would retur=
n a
different error, "Bad value", which is of course also tested. This means
that, depending on the value SET, the error message would be different.

However, we also feel that, apart from adding a little complexity to the
MTA, a MIB range that differs from the ETSI range possibly confuses the
users of the MIB, i.e. the operators. So why not use the ETSI range as th=
e
MIB range?

I have submitted draft -14 of the subscriber management mib internet
draft. It should be available soon in the usual places.

The only changes are:

the last sentence of the abstract was changed from:
     The Differentiated Services MIB (RFC 3289) is extended
     to provide the filtering functions needed here.
to
     The Differentiated Services MIB (RFC 3289) provides the
     filtering functions needed here, making use of classification items

     defined in this specification.
(see Harrie's email 19-January)

the description of docsSubMgtCpeControlTable was changed to read
     "This table AUGMENTs the docsIfCmtsCmStatusTable, adding
       four WRITEable objects, as well as a read-only object, which
       reflect the state of subscriber management on a particular CM."
(see Harrie's email 19-January)

the reference to the DOCSIS RFI spec was changed to
[ITU-T-J122]
        Second-Generation Transmission Systems for Interactive Cable
        Television Services, J.122, ITU-T, December, 2002.
(see Jean-Francois's email 29-January)

Respectfully submitted,
Wilson Sawyer

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP over Cable Data Network Working Group of the IETF.

	Title		: Management Information Base for Data Over Cable Service 
			  Interface Specification (DOCSIS) Cable Modem Termination 
			  Systems for Subscriber Management
	Author(s)	: W. Sawyer
	Filename	: draft-ietf-ipcdn-subscriber-mib-14.txt
	Pages		: 25
	Date		: 2004-2-16
	
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines a set of managed objects for SNMP-based
management of Data-over-Cable Service Interface Specification
(DOCSIS)-compliant Cable Modem Termination Systems. These managed
objects facilitate protection of the cable network from misuse by
subscribers.
This memo is a product of the IPCDN working group within the Internet
Engineering Task Force.  Comments are solicited and should be
addressed to the working group's mailing list at ipcdn@ietf.org
and/or the author.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-ipcdn-subscriber-mib-14.txt

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-ipcdn-subscriber-mib-14.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-ipcdn-subscriber-mib-14.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

Other
-added definitions:
	L Line Package

The L line package refers to the core signaling functionality as defined by PacketCable and IPCablecom. An MTA provides all L package elements, however the operator determines their application.

	E Line Package

The E line package refers to extensions, over and above the core L package, defined in support of international requirements. E line package elements are optional, vary from country to country, and are set by operator or regulatory requirements.

>2. Extend the SIZE range by one byte, indicating the repeatable tone sequence. This extra byte will immediately follow the first one (the length). In this case SIZE and desciptoins of all MIB objects should be modified. 

These objects will need to have their size extended in any case because the current cadence definition is too short to handle Germany per TS 101 183. The following proposed change handles the longer cadence and an additional octet to indicate repeatable characteristics.

    SYNTAX       OCTET STRING (SIZE(4..36)) 
        " The first two octets of the bit string represent the length in
          bits of the duration of the cadence. The third octet is
          used to represent repeatable characteristics. 00000000
          means repeatable, and 10000000 means non repeatable. Each
          Bit after the third octet represents 50 ms and 1
          represents ring and 0 represents silent. The first bit of
          the fourth octet is the first bit of the ring cadence. A
          total of 264 Bits can be set to represent 13200 ms of
          cadence cycle. This object is required for the E line package."

>As NCS Spec does not have any specific reqs for L-package except for ref to GR-506 (appendix A.2 of the NCS Spec), we feel comfortable with the original tComLabs' proposal: "A default value MUST be provided, but it is left up to the implementation to choose a reasonable default." 

My concern is whether the MIB Drs are going to flag this statement as having no value during review. The object, when queried,
is going to return a value whether the statement above is included in the description clause or not.

Suggestions:

1. The MTA MUST provide a default value for this object in accordance with published specifications for the country of operation.

Reference "TR 101 183 Specification."

OR

2. As Mark indicated DEFVAL can be used. Since tComlabs proposed this change, perhaps they could identify the exact DEFVAL clause to be used.

You should check what specifying a DEFVAL in the OBJECT-TYPE
definition means. RFC2578 says:

   7.9.  Mapping of the DEFVAL clause

   The DEFVAL clause, which need not be present, defines an acceptable
   default value which may be used at the discretion of an agent when an
   object instance is created.  That is, the value is a "hint" to
   implementors.

   During conceptual row creation, if an instance of a columnar object
   is not present as one of the operands in the correspondent management
   protocol set operation, then the value of the DEFVAL clause, if
   present, indicates an acceptable default value that an agent might
   use (especially for a read-only object).

There is more text in 2578, but the above should make it clear that it
is at the discretion of the agent if it will use the exact DEFVAL value
speified or not. It is only a "hint". It does help though that in case
of a row-create, that column does nto have to be specified, since the
presence of a DEFVAL clause means that the agent will fill out
an acceptable default value (possibly the one specified).

Hope this helps,
Bert

I have no real text and considering your comment it maybe is better 
this way.
I can immagine that in the future filtering and, for instance, metering 
will
be done. So explicitly forbidden it would not be a good idea.

Yes, you are right. The augment takes care of of the existance of
an entry for a particular modem and the FilterGroupTable is
not affected by that.
Correct me if I am wrong, but the filter group could be seen as an
available configuration. Whether it is used or not is not a problem.
This is similar to the approach of the DIFFSERV-CONFIG-MIB, only
here you point to a specific sort of datapath element, the classifier
element.

Due to this I maybe found a 'bug', not sure if this is really true.
In your MIB you always refer to the first pass of an classifier
element, a diffServClfrElementEntry. However, the DIFFSERV-MIB also
has a diffServClfrTable. This table is the common index of the
complete classifier, not jsut an element.
I beleive the difServClfrTable would be the right one to point to.

Please read the commented 'text' above the diffServClfrTable of the 
DIFFSERV-MIB.
I beleive that reflects this thought.


Harrie

My apologies to Harrie and the IPCDN mailing list. I was able to approve
this email from Harrie from February 2nd only after I threw away about 550+
spam emails on the IPCDN approval list... Hopefully this shouldn't happen
again.

I have no real text and considering your comment it maybe is better 
this way.
I can immagine that in the future filtering and, for instance, metering 
will
be done. So explicitly forbidden it would not be a good idea.

Yes, you are right. The augment takes care of of the existance of
an entry for a particular modem and the FilterGroupTable is
not affected by that.
Correct me if I am wrong, but the filter group could be seen as an
available configuration. Whether it is used or not is not a problem.
This is similar to the approach of the DIFFSERV-CONFIG-MIB, only
here you point to a specific sort of datapath element, the classifier
element.

Due to this I maybe found a 'bug', not sure if this is really true.
In your MIB you always refer to the first pass of an classifier
element, a diffServClfrElementEntry. However, the DIFFSERV-MIB also
has a diffServClfrTable. This table is the common index of the
complete classifier, not jsut an element.
I beleive the difServClfrTable would be the right one to point to.

Please read the commented 'text' above the diffServClfrTable of the 
DIFFSERV-MIB.
I beleive that reflects this thought.

#1 - agreed.

#2 - do not agree: it does not seem logical to have single DEFVAL value for
the MIB object which has cross-country applicability.

>As NCS Spec does not have any specific reqs for L-package except for ref to
GR-506 (appendix A.2 of the NCS Spec), we feel comfortable with the original
tComLabs' proposal: "A default value MUST be provided, but it is left up to
the implementation to choose a reasonable default." 

My concern is whether the MIB Drs are going to flag this statement as having
no value during review. The object, when queried,
is going to return a value whether the statement above is included in the
description clause or not.

Suggestions:

1. The MTA MUST provide a default value for this object in accordance with
published specifications for the country of operation.

Reference "TR 101 183 Specification."

OR

2. As Mark indicated DEFVAL can be used. Since tComlabs proposed this
change, perhaps they could identify the exact DEFVAL clause to be used.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP over Cable Data Network Working Group of the IETF.

	Title		: Management Event MIB for PacketCable/IPCablecom MTAs
	Author(s)	: W. De Ketelaere, E. Nechamkin
	Filename	: draft-ietf-ipcdn-pktc-eventmess-03.txt
	Pages		: 28
	Date		: 2004-2-18
	
This memo defines a portion of the Management Information Base (MIB)  
for use with network management protocols in the Internet community. 
In particular, it provides a common data and format definition for  
events and specifies by what means events are transmitted for  
PacketCable/IPCablecom compliant Multimedia Terminal Adapter devices. 
This memo specifies a MIB module in a manner that is compliant to the 
SNMP SMIv2 [5][6][7].  The set of objects are consistent with the 
SNMP framework and existing SNMP standards.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-ipcdn-pktc-eventmess-03.txt

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-ipcdn-pktc-eventmess-03.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-ipcdn-pktc-eventmess-03.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

The pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence objects are redundant. These objects are recommended to be deleted from the NCS Signaling MIB. The use of separate pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence objects is a carryover from the L line package and they are not needed in the E line package. Instead, normal ring and ring splash cadences can be defined using the pktcSigDevRingCadenceTable object.

Folks,

Some operators are using SNMPv2c for MTA device management (and will
continue to do so for some period of time). We've been discussing the
impact that the unsecure SNMPv2 mgmt has on the MTA MIB with the
PacketCable OSS vendor team. I would like to share some of our thoughts
and our suggestions to make sure that we are doing the right thing and
to that those proposed changes are sound and can later be reflected in
the IETF ID mtamib draft 04.

Note that the IETF ID mtamib draft 03 does have a fairly detailed
security consideration section and recommends the use of secure SNMPv3.
Yet, the MIB module and its objects definitions assume v3 only and we've
found that the implementers feel that there should be clear guidance
when v2c mgmt is used. Some MIB objects don't mean anything when v2 is
used (these objects are related to the key mgmt for the security
relationship with the SNMP entity or prov server
(pktcMtaDevProvSolicitedKeyTimeout and alike), or to key/hash values for
the config file that are passed in secure v3 mode when the MTA
enrollment mechanism is used (pktcMtaDevProvConfigKey), etc.=20

At this point, our suggestions are as follows:
 - maintain the compliance statements as-is, all MTAs will support
SNMPv3 and when v3 is used, all the objects as defined in draft 03 make
sense (at least, we think they do);
 - define in our PacketCable MIB framework the mib views, access right
for v2 mgmt,
 - for the specific objects that do not mean anything in v2, enhance the
DESCRIPTION clause to state what the device must do if v2 mgmt is used,
that is, specify the MTA's behavior when receiving SNMPv2 SET & GET
operations on those v3-specific objects.
 - Suggestions:
   add something like this in the impacted objects:
   for pktcMtaDevProvConfigKey:
             This object should not be used in non secure SNMPv3 modes.
             In non secure SNMPv3 modes, the MTA MUST return an=20
             'inconsistentValue' in response to SNMP SET operations,=20
             and the MTA MUST return a 'genErr' error in response to=20
             SNMP GET operations."
   for pktcMtaDevProvConfigHash:
             When the MTA SNMP Enrollment mechanism is not in use, the
             hash value is provided in the configuration file itself=20
             and it is also calculated by the MTA. This object value
             MUST represent the hash value calculated by the MTA.
             When the MTA SNMP Enrollment mechanism is not in use, the
             MTA must reject all SNMP SET operations on this object and
             return an 'inconsistentValue' error.
   These are just 2 examples but they basically say:
     - if unsecure v2 is used, SNMP SET on the object =3D>
'inconsistentValue', SNMP GET =3D> 'genErr'
   This seems to be consistent with RFC 3416 (one could argue that
'noAccess' could be returned as well).

Question:
Is this the proper way to do this to provide some info in the MIB module
as our MTA implementers have been asking for? We plan on adding some
more details on the VACM model (MIB views, access rights and object
trees that cannot be accessed without the proper security policies.

Thanks in advance for any input on this,
Jean-Francois=20

> The pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence=20
> objects are redundant.=20
I am not sure I can completely agree with this statement (if I =
understand it correctly). Both of these objects are required for =
Euro-L-package, because of the way the RG and RS signalls are currently =
defined:

For Euro-L-Package:=20
   - RG -> pktcSigDevStandardRingCadence
   - RS -> pktcSigDevRingSplashCadence

The "pktcSigDevRingCadenceTable" contains the cadence values for the =
E-package. Having in mind that E-package is optional, and L-package is =
mandatory, I am not sure I understand how pktcSigDevStandardRingCadence =
and pktcSigDevRingSplashCadence can be "merged" into the =
"pktcSigDevRingCadenceTable".

Or, are you suggesting that "pktcSigDevRingCadenceTable" should contain =
the RG and RS cadencies for Euro-L-Package along with the values for =
E-package? If yes, I think the proper mapping of the table indexes to =
the corresponding signal should be somehow defined, and corresponding =
modifications of the Euro-L-Package should also be put in place.=20

Though from the MIB optimization stand point of view the proposed =
modification might make sense, however, from the currently imlemented =
and intended funtionality prospective it looks unnecessary (please =
correct me if my understanding of your proposal deviates from what you =
had in mind).

Interesting. Thanks for pointing that out. However, I don't follow why the mapping has been made that way in the "Clarification of L Package for Euro-PacketCable Document v6.0 (2004/1/20)."

The objects referenced in 2.19 and 2.21 for the L package rg and rs cadences are in the international group with a max cadence of 13.2s. The other distinctive ring cadences in the above document map to core L package objects r0..r7 with a max cadence of 6.0s. The cadence mapping seems to be inconsistent. I would have expected the 2.19 and 2.21 cadence for rg/rs to be mapped to the pktcSigDevRgCadence and pktcSigDevRsCadence core L package objects. International cadences would then be handled via the E package extensions and associated object (pktcSigDevRingCadenceTable).

Wim,

Can you comment/clarify why the rg/rs cadences are mapped to objects in the international group instead of the pktcSigDevRgCadence and pktcSigDevRsCadence objects? Thanks.

Gordon

I am not sure I can completely agree with this statement (if I understand it correctly). Both of these objects are required for Euro-L-package, because of the way the RG and RS signalls are currently defined:

For Euro-L-Package: 
   - RG -> pktcSigDevStandardRingCadence
   - RS -> pktcSigDevRingSplashCadence

The "pktcSigDevRingCadenceTable" contains the cadence values for the E-package. Having in mind that E-package is optional, and L-package is mandatory, I am not sure I understand how pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence can be "merged" into the "pktcSigDevRingCadenceTable".

Or, are you suggesting that "pktcSigDevRingCadenceTable" should contain the RG and RS cadencies for Euro-L-Package along with the values for E-package? If yes, I think the proper mapping of the table indexes to the corresponding signal should be somehow defined, and corresponding modifications of the Euro-L-Package should also be put in place. 

Though from the MIB optimization stand point of view the proposed modification might make sense, however, from the currently imlemented and intended funtionality prospective it looks unnecessary (please correct me if my understanding of your proposal deviates from what you had in mind).

It's might also be worth noting that the "pktcSigDevRgCadence" and =
"pktcSigDevRsCadence" on one hand, and "pktcSigDevStandardRingCadence" =
and "pktcSigDevRingSplashCadence" - on the other have different =

Exactly. This is precisely what the pktcSigDevRingCadenceTable object is defined to handle (international ring cadences to 13.2s) using the V5.x "cr(x)" mechanism noted in the object description. For example, an international operator could define cr5 for standard ring and cr9 for ring splash, etc for up to 128 international cadences.

V5.x defined 128 possible ring cadences for international ring messages without concern for what those cadences are named. The 101 909-4 spec does not name these cadences either and the name should not be a concern for the MIB definitions.

It's might also be worth noting that the "pktcSigDevRgCadence" and "pktcSigDevRsCadence" on one hand, and "pktcSigDevStandardRingCadence" and "pktcSigDevRingSplashCadence" - on the other have different requirement for the Cadence timing granularity, hence the "pktcSigDevRgCadence" and "pktcSigDevRsCadence" could not have been used to represent Euro-PC Cadence resolution requirement reflected in "pktcSigDevStandardRingCadence" and "pktcSigDevRingSplashCadence".

Interesting. Thanks for pointing that out. However, I don't follow why the mapping has been made that way in the "Clarification of L Package for Euro-PacketCable Document v6.0 (2004/1/20)."

The objects referenced in 2.19 and 2.21 for the L package rg and rs cadences are in the international group with a max cadence of 13.2s. The other distinctive ring cadences in the above document map to core L package objects r0..r7 with a max cadence of 6.0s. The cadence mapping seems to be inconsistent. I would have expected the 2.19 and 2.21 cadence for rg/rs to be mapped to the pktcSigDevRgCadence and pktcSigDevRsCadence core L package objects. International cadences would then be handled via the E package extensions and associated object (pktcSigDevRingCadenceTable).

Wim,

Can you comment/clarify why the rg/rs cadences are mapped to objects in the international group instead of the pktcSigDevRgCadence and pktcSigDevRsCadence objects? Thanks.

Gordon

> The pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence 
> objects are redundant. 
I am not sure I can completely agree with this statement (if I understand it correctly). Both of these objects are required for Euro-L-package, because of the way the RG and RS signalls are currently defined:

For Euro-L-Package: 
   - RG -> pktcSigDevStandardRingCadence
   - RS -> pktcSigDevRingSplashCadence

The "pktcSigDevRingCadenceTable" contains the cadence values for the E-package. Having in mind that E-package is optional, and L-package is mandatory, I am not sure I understand how pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence can be "merged" into the "pktcSigDevRingCadenceTable".

Or, are you suggesting that "pktcSigDevRingCadenceTable" should contain the RG and RS cadencies for Euro-L-Package along with the values for E-package? If yes, I think the proper mapping of the table indexes to the corresponding signal should be somehow defined, and corresponding modifications of the Euro-L-Package should also be put in place. 

Though from the MIB optimization stand point of view the proposed modification might make sense, however, from the currently imlemented and intended funtionality prospective it looks unnecessary (please correct me if my understanding of your proposal deviates from what you had in mind).

It would be better to mark the MIB with usage like E-Package or =
L-package.
This avoids possible confusion.

It's might also be worth noting that the "pktcSigDevRgCadence" and =
"pktcSigDevRsCadence" on one hand, and "pktcSigDevStandardRingCadence" =
and "pktcSigDevRingSplashCadence" - on the other have different =
requirement for the Cadence timing granularity, hence the =
"pktcSigDevRgCadence" and "pktcSigDevRsCadence" could not have been used =
to represent Euro-PC Cadence resolution requirement reflected in =
"pktcSigDevStandardRingCadence" and "pktcSigDevRingSplashCadence".

Interesting. Thanks for pointing that out. However, I don't follow why =
the mapping has been made that way in the "Clarification of L Package =
for Euro-PacketCable Document v6.0 (2004/1/20)."

The objects referenced in 2.19 and 2.21 for the L package rg and rs =
cadences are in the international group with a max cadence of 13.2s. The =
other distinctive ring cadences in the above document map to core L =
package objects r0..r7 with a max cadence of 6.0s. The cadence mapping =
seems to be inconsistent. I would have expected the 2.19 and 2.21 =
cadence for rg/rs to be mapped to the pktcSigDevRgCadence and =
pktcSigDevRsCadence core L package objects. International cadences would =
then be handled via the E package extensions and associated object =
(pktcSigDevRingCadenceTable).

Wim,

Can you comment/clarify why the rg/rs cadences are mapped to objects in =
the international group instead of the pktcSigDevRgCadence and =
pktcSigDevRsCadence objects? Thanks.

Gordon

I am not sure I can completely agree with this statement (if I =
understand it correctly). Both of these objects are required for =
Euro-L-package, because of the way the RG and RS signalls are currently =
defined:

For Euro-L-Package:=20
   - RG -> pktcSigDevStandardRingCadence
   - RS -> pktcSigDevRingSplashCadence

The "pktcSigDevRingCadenceTable" contains the cadence values for the =
E-package. Having in mind that E-package is optional, and L-package is =
mandatory, I am not sure I understand how pktcSigDevStandardRingCadence =
and pktcSigDevRingSplashCadence can be "merged" into the =
"pktcSigDevRingCadenceTable".

Or, are you suggesting that "pktcSigDevRingCadenceTable" should contain =
the RG and RS cadencies for Euro-L-Package along with the values for =
E-package? If yes, I think the proper mapping of the table indexes to =
the corresponding signal should be somehow defined, and corresponding =
modifications of the Euro-L-Package should also be put in place.=20

Though from the MIB optimization stand point of view the proposed =
modification might make sense, however, from the currently imlemented =
and intended funtionality prospective it looks unnecessary (please =
correct me if my understanding of your proposal deviates from what you =
had in mind).

The pktcSigDevStandardRingCadence and pktcSigDevRingSplashCadence =
objects are redundant. These objects are recommended to be deleted from =
the NCS Signaling MIB. The use of separate pktcSigDevStandardRingCadence =
and pktcSigDevRingSplashCadence objects is a carryover from the L line =
package and they are not needed in the E line package. Instead, normal =
ring and ring splash cadences can be defined using the =
pktcSigDevRingCadenceTable object.
