ETH-PT (Control LAN Ethernet)
The TN799DP Control LAN (C-LAN) packet port circuit pack provides TCP/IP
connection to adjuncts applications such as CMS, Intuity, and DCS Networking.
The C-LAN circuit pack has one 10baseT Ethernet connection and up to 16 DS0
physical interfaces for PPP connections. Multiple C-LAN circuit packs in a system
provide additional TCP/IP capacity.
An RSCL (remote socket control link) links the C-LAN and the media server to
pass call-control and other management information. Since one link serves every
port on the circuit pack, maintenance of the RSCL is part of the C-LAN circuit
pack’s maintenance.
NOTE:
The TN799DP C-LAN circuit pack replaces the PGATE and PI circuit packs
in the G3r and G3si/G3vs systems, respectively. The PGATE or PI can be
used with the C-LAN to create an X.25-to-TCP/IP bridge for adjunct and
DCS connections.
Control LAN Congestion Controls
The switch activates congestion controls on C-LAN when it detects buffers
exceeding the threshold. The switch releases the congestion controls when the
C-LAN reports that its buffers have returned to normal levels.
