ETH-PT (Control LAN Ethernet)
The TN799 Control LAN (CLAN) packet port ci rcuit pack provid es TCP/IP
connection to adjunc ts applications suc h as CMS, Intuity, and DCS Networking.
The CLAN circuit pack has one 1 0baseT Ethernet connection and up to 16 DS0
physical interfaces f or PPP connections. Multiple CLAN circuit p acks (maximum
2 per switch) in a system g ives additional TCP/IP capacity.
A remo te soc ket c ont rol lin k (RSCL ) link s the C LAN a nd th e SPE to p ass c all
control and other managemen t information. Since one link serves all the port s on
the circuit pac k, 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 adjunc t 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.
