CLAN-BD (Control LAN Circuit Pack)
MO Name in Log Alarm
Level
Control LAN circuit pack
The TN799 Control LAN (C-LAN) circuit pack provides TCP/IP connection to adjunct
applications such as CMS, INTUITY, and DCS Networking. The C-LAN circuit pack has one
100BASE-T Ethernet connection and up to 16 DS0 physical interfaces for PPP connections.
C-LAN also extends ISDN capabilities to csi models by providing packet bus access. The
TN799DP also supports QoS.
A RSCL (remote socket control link) links the C-LAN and the server to pass call control and
other management information. Because one link serves every port on the circuit pack,
maintenance of the RSCL is part of the C-LAN circuit-pack maintenance.
C-LAN socket load balancing
The C-LAN socket load balancing feature provides for a more uniform balancing of the load
across the available C-LANs. With this feature, an IP endpoint registers to the C-LAN with the
least number of used sockets (regardless of the number of available sockets). This applies to
the following IP endpoints:
● H.245, H.248, and H.323 signaling groups
● H.323 stations

● SIP endpoints
Socket counts include H.245 and H.248 endpoints but the load-balancing algorithm will not be
used for registering these endpoints. Sockets used by adjuncts are not included in the socket
count.
Note:
Note: This allocation is performed for the C-LANs assigned within each network region,
independently of the C-LANs assigned to other network regions.
The system logs a warning to the error log when a TN799x circuit pack has reached the socket
usage value specified in the Number of CLAN Sockets Before Warning field on the
ip-interfaces form. The warning can be viewed using display errors.
