Snmp Agent And Subagents; Fast Call Setup - Dialogic Vision CX Video Administration Manual

Overview of the CX Video Gateway

SNMP agent and subagents

The CX Video Gateway provides an SNMP interface that lets you monitor gateway
performance, view statistics, monitor a RAID server, and receive alarms. The
gateway uses Net-SNMP as a master agent and the DS1, Call Server, and RAID
subagents. The master agent supports SNMPv1, SNMPv2c, and SNMPv3.
For more information, see the Dialogic® Vision™ SNMP Reference Manual.

Fast call setup

The CX Video Gateway supports the following techniques for speeding up 3G-324M
call setup time:
Packed H.245 messages, which groups independent H.245 messages together
•
into a single NSRP command frame. This reduces the number of message
round-trips, and thus reduces call setup time.
Windowed Simple Retransmission protocol (WNSRP), an H.245 transport
•
improvement technique that is standardized in ITU-T Recommendation H.324
and accepted into the 3G-324M standard by 3GPP.
Media oriented negotiation acceleration (MONA), which unites the
•
technologies for H.324 call setup acceleration under a common framework.
MONA was approved by the ITU-T in August 2006, and is recommended in
3GPP Release 7 in TR 26.911.
Note: You must obtain the appropriate license to use one of these techniques. For
information, see the readme file for this release.
The CX Video Gateway does not support:
The signaling preconfigured channel (SPC) MONA technique.
•
Preconfigured channel media frames encapsulated in MONA signaling
•
preference messages.
