RE: [ipcdn] draft-ipcdn-pktc-signaling-08, further changes;result of conference call
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."
DEFVAL { 800 }
::= { pktcNcsEndPntConfigEntry 33 }
Eugene.

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
