ETH-PT (Control LAN Ethernet)
The TN799 Control LAN (CLAN) packet port ci rcuit pack provid es TCP/IP
connection to adjunc ts applications s uch as CMS, Intuity, and DCS Networking.
The CLAN circuit pack has one 10b aseT Ethernet connection and up to 16 DS0
phys ical inter fac es for PPP con nect ions. Mult iple CLAN c irc uit p ack s in a s ystem
gives additional TCP/IP capacity.
A remo te soc ket c ontr ol lin k (RSCL ) link s the C LAN a nd th e SPE to p ass c all
control and other management information. Since one link serves all the ports o n
the circuit pack, maintenance of the RSCL is part of the CLAN circ uit pack
maintenance.
NOTE:
The CLAN TN799 circuit pack replac es the PGATE and PI circuit packs in
the G3r and G3si/G3vs systems, respec tively. The PGATE or PI can be
used with the CLAN to create an X.25-to-TCP/IP bridge for ad junct and
DCS connections.
Control LAN Congestion Controls
The switch activates cong estion controls on CLAN when it detec ts buffers
exceeding the threshold . The switch releases the congestion c ontrols when the
CLAN reports that its buffer level has returned to normal levels.

If congestion: Then the switch:
Persists for a 14-minute interval, Raises MINOR alarm.
Exhausts buffers, Raises MINOR alarm.
Ceases for 12 minutes, Retires MINOR alarm.
