PPP-PT (Control LAN Packet/Port)
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 1-10baseT 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 combines the functions of the PGATE and PI
circuit packs into one circuit pack. The PGATE or PI can be used with the
CLAN to create an X.25 to TCP/IP bridge for adjunct and DCS connectivity.
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.

UU is the universal cabinet number (1 for PPN, 2 - 44 for EPNs). C is the carrier designation (A, B,
C, D, or E). SS is the number of the slot in which the circuit pack resides (01 to 21). pp is the two
digit port number (01, 02, etc.).
