Proposed changes to draft-ipcdn-pktc-signaling-08:
-------------------------------------------------
(ftp://ftp.ietf.org/internet-drafts/draft-ietf-ipcdn-pktc-signaling-08.t
xt)


OPEN ISSUE (Need inputs):
---- ----- 
+ Definition of the MIB Object 'pktcSigDevToneSteady'. This seems to
allow for dual interpretation.

 
Strongly recommended changes (based on feedback received in the IPCDN
WG):
-------- ----------- -------    

Recommendation #1 (Reason: Technical):
-------------------------------------
+ pktcSigDevMultiFreqToneTable


- Extend the MultiFrequency table to support 4, instead of 2 frequencies
today (First, Second, Third, Fourth instead of Pri and Sec). i.e. 

  - pktcSigDevToneFirstFreqValue            

  - pktcSigDevToneSecondFreqValue                    

  - pktcSigDevToneThirdFreqValue            

  - pktcSigDevToneFourthFreqValue

 
- Re-enumerate 'pktcSigDevToneNumber' to 1..8 (Reason: There is no need
for anything more than 8 tones per tone type)

- Make all the entries in this table to be 'read-only' (Reason: Will not
require updating during run-time)

- Update the DESCRIPTIONs appropriately (Reason: Addition of 4
frequencies changes the Modulation/Summation schemes)

 
 

Recommendation #2:
-----------------

+ Deletion of MIB Objects

    - Delete the MIB Objects 'pktcNcsEndPntConfigTxGain' and
'pktcNcsEndPntConfigRxGain' (Reason: Proposal withdrawn)

    - Delete the MIB Object 'pktcSigDevToneNumFrequencies' (Reason:
Redundant)

 



Editorial/Semantic Changes:

---------------------- ----------

- Rename 'pktcSigDevToneFrequencyNumber' as 'pktcSigDevToneNumber'
(Reason: Semantics)

- Move the MIB Object 'pktcSigDevToneType' to the Tone Table (Reason:
MIB author guidelines)

 

Additional suggested changes:
----------  -------- --------
- 'pktcSigDevMultiFreqToneTable' could be indexed using only one MIB
Object, easing implementation.


Define FreqToneTable as being indexed only by pktcSigDevToneNumber
(unique index for each entry)

 
   pktcSigDevMultiFreqToneEntry    OBJECT-TYPE  
       ...............

       INDEX {pktcSigDevToneNumber}  
       ::= { pktcSigDevMultiFreqToneTable 1 }  

 

   PktcSigDevMultiFreqToneEntry ::= SEQUENCE {

         pktcSigDevToneNumber                    Unsigned32,
         pktcSigDevFreqToneType                  ToneType
.
.
.
   }

   pktcSigDevToneNumber OBJECT-TYPE  
       SYNTAX       Unsigned32(1..168) 
       MAX-ACCESS   not-accessible
       STATUS       current  
       DESCRIPTION  
          "This MIB Object is a unique number identifying each entry in
..."
