ETH-PT (Control LAN Ethernet)

ETH-PT (Control LAN Ethernet)
S8700 | 8710 / S8500 / S8300
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.
Note:
Note: S8300 / G700: Although the ETH-PT MO is provided for a G700 media gateway,
this MO only partially supports the G700’s MG-ANN virtual media module.
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:
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.

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