Initial Configuration Procedures
Configuring Digital Voice
To configure basic T1/E1 controller settings to support PPP, High-Level Data Link Control (HDLC), or
Frame Relay (FR), follow these steps, beginning in global configuration mode:
For additional information about configuring specific features, see the following references:
• For PPP, HDLC, or FR, consult the online master index for the Cisco IOS release you are using.
• For loopback diagnostics, or for configuring controller channel groups, channel-associated
signaling (CAS) voice groups, or time-division multiplexing (TDM) cross-connects, see the
Cisco IAD2430 Series Integrated Access Devices Software Configuration Guide.
Verifying and Saving Your Configuration
To verify the configuration and save it in NVRAM so that the configuration remains in effect if the
Cisco IAD is restarted, enter the following commands:
Step 7 Router(config-ctrl)# no shutdown Activates the T1/E1 controller.
Step 8 Router(config-ctrl)# exit Exits controller configuration mode.
Step 9 Router(config)# exit Exits configuration mode.
Step 10 Router# show controller T1/E1 1/0 Verifies the controller configuration. Slot and port
numbers vary.
Command Purpose
Command Purpose
Step 1 Router(config)# controller T1/E1 1/0 Enters controller configuration mode by controller
number. Slot and port numbers vary.
Step 2 Router(config-ctrl)# mode cas Configures channel-associated signaling.
Step 3 Router(config-ctrl-cas)# framing esf Configures framing.
Step 4 Router(config-ctrl-cas)# linecode b8zs Configures line encoding format.
Step 5 Router(config-ctrl-cas)# framing {sf | esf} If necessary, changes the DS1 link framing format.
The default is SuperFrame (sf).
Step 6 Router(config-ctrl-cas)# ds0-group 1 timeslots 1-24
type e&m-immediate-start
Configures the DS0 group.
Step 7 Repeat Step 3 through Step 6 for each additional DS0 group. Configures additional DS0 groups on the T1/E1
interface. You can configure as many as 24 DS0
groups on a T1/E1.
Step 8 Router(config-ctrl-cas)# exit Exits controller configuration mode.
Step 9 Router(config-ctrl)# no shutdown Activates the T1/E1 controller.
Step 10 Router(config-ctrl)# exit Exits controller configuration mode.
Step 11 Router(config)# exit Exits configuration mode.
Step 12 Router# show controller T1/E1 1/0 Verifies the controller configuration. Slot and port
numbers vary.
