Note The Cisco AS5350XM and Cisco AS5400XM universal gateways each support only one type of
WAN feature card at a time. See Chapter 7, “Troubleshooting,” for more information.
The CT3 feature card provides physical line termination for up to 672 DS0 channels and uses onboard
High-Level Data Link Control (HDLC) controllers to terminate digital (ISDN) calls.
You can use the bantam jack ports on the feature card to monitor a T1 line or to test any of the individual
T1 channels in drop and insert mode.
You can install a CT3 feature card in any feature card slot in a universal gateway chassis.
