Configuring and Troubleshooting Line Card Interfaces
Available Configurations for the 1-Port Channelized OC-12/STM-4 (DS1/E1) ISE Line Card
The 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card channelizes up to 840 channel groups of
DS1, fractional DS1, or NxDS0 and 168 MLFR/MLPPP T1 bundles. It provides 12 STS-1 interfaces, in
either VT-15 mode or CT3 mode. In either case, each STS-1 contains 28 T1 channels for a total of 336
T1 channels per line card. In addition, E1 channels are supported under SDH framing, with
Administrative Unit Group (AUG) mapping set to AU-4. Configuration of the 63 E1s is done per
Tributary Unit Group-3 (TUG-3). Each TUG-3 comprises seven TUG-2s. Each TUG-2 can be configured
to carry up to three E1s mapped into TU-12s.
For more information on configuring the 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card, refer
to the Cisco IOS Software Configuration for the Cisco 12000 Series 1-Port Channelized OC-12c/STM-4
to DS1/E1 Line Card document.
Configuring the 1-Port Channelized OC-48/STM-16 ISE and 4-Port Channelized
OC-12/STM-4 ISE Line Cards
The following procedure describes how to perform a basic controller configuration. After you verify that
the new line card is installed correctly, enter the privileged EXEC mode with the enable command. The
system prompts you for a password if one is required. Use the configure command to configure the
controller.
