Overview
You can install a T1 or E1 dial feature card in any dial feature card slot of the universal gateway chassis.
(See Figure 3-1 through Figure 3-3.)
Each T1 or E1 DFC provides physical line termination for multiple DS-0 channels and uses onboard
HDLC controllers to terminate digital (ISDN) calls. For network specifications see Table 3-1 and
Table 3-2. You can use the bantam ports on the DFC to monitor a line.
Note The Cisco AS5350 and Cisco AS5400 support only one type of WAN DFC at a time. Refer
to Chapter 6, “Troubleshooting” for more information.
