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
