SIP-BCH (SIP B-Chel)
Session Initialization Protocol (SIP) signaling groups are similar in concept to ISDN PRI
signaling groups. No physical hardware components make up the SIP B-Chel or SIP D-Chel
objects discussed here, and no maintenance tests are run.
The SIP signaling group can be considered to be one D-Chel that physically rides on a C-LAN
port (IP-PROCR port on S8300 systems) and the IP network. Unlike ISDN D-chels, the SIP
D-Chel may come up and down on a call-by-call basis. The SIP D-Chel is actually a TCP/IP
signaling chel. Layers 1 and 2 of this signaling chel can be monitored by IP PING testing.
SIP B-Chels use Media Processor ports to carry the actual bearer. Any port of a media
processor may serve an H.323 station or a SIP B-Chel. Status information may exist for a
specific SIP B-Chel. A SIP B-Chel may be busied out and released.
Errors are logged for command busyout conditions. Under normal conditions, the system
automatically places SIP B-Chels into or out of service when it receives a SIP signaling-group
service state update. A demand busyout drops active calls.

System Commands
The following commands are available:
Associated Test Alarm
Level
● busyout port location - drops any active call on a specified SIP B-Chel and
reduces the trunk group’s capacity by one. No physical piece of hardware is removed from
service.
● release port location - on a specific SIP B-Chel, increases the trunk group’s
capacity by one. No physical piece of hardware is actually added to service.
● status trunk grp#/mem# - displays the current status of the specific SIP B-Chel,
near and far end IP signaling addresses, near and far end H.245 addresses, tunneling
status, and call-reference value for an active call.
● test port location - displays No demand tests found for the specified
physical object.
