[ipcdn] FW: IPCDN Digest, Vol 15, Issue 16
Eugene,
Thank you for reviewing the GR 506 document however, I do not fully agree with your proposal.
Per your email, GR 506 states:
Table 12-2. Flash Response Enabled Timing
On-Hook Duration (milliseconds) SPCS Interpretation
< 200 Hit
200 to 300 Hit or Flash
300 to 1100 Flash
1100 to 1550 Flash or Disconnect
>1550 Disconnect
This implies that the network MUST accept 300 to 1100 milliseconds as hook flash and must NOT accept less than 200 ms or more than 1550 ms.
The ranges of 200 to 300 and 1100 to 1550 are ranges where the network may accept or may reject the timing.
I do agree that some changes may be appropriate in the ranges of min/max values..
I do not agree with your proposed max default value and propose the following to bring the SigMIB into alignment with GR 506.
Current rev8 text:

" This is the minimum time a line needs to be on hook for a
valid hook flash. The value of this object MUST be
greater than the value of

pktcNcsEndPntConfigMinHookFlash MUST be less than
pktcNcsEndPntConfigMaxHookFlash. This object MUST only be
set via the configuration file during the provisioning

Furthermore, given the possibility for the 'pulse dial'

be greater than the value contained by the MIB Object

Sumanth,
Looking further at the Bellcore specs for pulse flash requirements (GR-506-CORE "LSSGR: Signaling for Analog Interfaces"), it turnes out that the requirements for the pulse range for flash are higher than it is currently allowed by the "pktcNcsEndPntConfigMaxHookFlash" MIB Object. Bellcore specs say that flash MUST be 300-1100, but may be up to 1550:
Table 12-2. Flash Response Enabled Timing
On-Hook Duration (milliseconds) SPCS Interpretation
< 200 Hit
200 to 300 Hit or Flash
300 to 1100 Flash
1100 to 1550 Flash or Disconnect
>1550 Disconnect
To better meet the Bellcore specs requirements, the following modification of the MIB Object's range is proposed:
pktcNcsEndPntConfigMaxHookFlash OBJECT-TYPE
SYNTAX Unsigned32 (20..1550)
UNITS "Milliseconds"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
" This is the maximum time a line needs to be on hook for a
valid hook flash. The value of
pktcNcsEndPntConfigMaxHookFlash MUST be greater than
pktcNcsEndPntConfigMinHookFlash. This object MUST only be
set via the configuration file during the provisioning
process."

Jean-Francois,
I concur. Unless there are objections, I will be presenting the final proposal to this group in the next week.

Sumanth,
Thanks for inviting anyone from IETF ipcdn to attend the discussion and for the notes.
We have not seen one comment on your posting in 15 days so the proposal should be good enough. Per the IETF#63 meeting, the action item on the signaling MIB was: # AI: authors to close one open issue on tone table by August 20. # Ask Randy to review final proposal.
Can you put out the proposed changes in the form of updated object definitions to the list so we can see all the aggregated changes?
Based on our discussions, we are getting close to the end on this one and I would like to set the date of next Friday, September 2nd to have a consensus on the technical changes to allow a draft09 publication by mid-September at the latest.
Thanks,
Jean-François
