ETH-PT (Control LAN Ethernet)
The TN799 Control LAN (CLAN) packet port circuit pack provides TCP/IP
connection to adjuncts applications such as CMS, Intuity, and DCS Networking.
The CLAN circuit pack has one 10baseT Ethernet connection and up to 16 DS0
physical interfaces for PPP connections. Multiple CLAN circuit packs in a system
gives additional TCP/IP capacity.
A remote socket control link (RSCL) links the CLAN and the SPE to pass call
control and other management information. Since one link serves all the ports on
the circuit pack, maintenance of the RSCL is part of the CLAN circuit pack
maintenance.
NOTE:
The CLAN TN799 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 CLAN to create an X.25-to-TCP/IP bridge for adjunct and DCS
connections.
Control LAN Congestion Controls
The switch activates congestion controls on CLAN when it detects buffers
exceeding the threshold. The switch releases the congestion controls when the
CLAN reports that its buffer level has returned to normal levels.
