Online Installation and Removal of the T1 or E1 Feature Card Figure 3-3 8-Port T1 or E1 Feature Card Chapter 3 T1 and E1 Feature Cards 29030 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. Each T1 or E1 feature card 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 jack ports on the feature card to monitor a line. Table 3-1 T1 Feature Card Network Specifications Description Line rate Data rate (per port) Standards Input impedance Specification 1.544 Mbps number x 56 or number x 64 kbps, where number = 1 to 24 AT&T Pub. 62411, 54016, and 43081, and ANSI T1.403 100 ohm per port Table 3-2 E1 Feature Card Network Specifications Description Line rate Data rate (per port) Input impedance Specification 2.048 Mbps number x 56 or number x 64 kbps, where number = 1 to 31. 75 or 120 ohm per port Note The factory default setting for the E1 ports is 120 ohm. For information about changing the impedance, see the "Configuring Input Impedance for the E1 Feature Card" section on page 3-11. Online Installation and Removal of the T1 or E1 Feature Card To remove a feature card without dropping any calls or connections, you will need to take the feature card out of service by using the busyout command to disable the feature card. The busyout command is executed on a per-feature card basis and will disable the card after waiting for the active services to terminate. If there are active calls on the feature card after you execute the busyout command, wait for the calls to drop. To view the status of the termination process, use the show busyout command.
