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: Command Description Step 1 Router(config)# controller t1/e1 1/0 Step 2 Router(config-ctrl)# clock source {internal | line | loop-timed} Enters controller configuration mode by controller number. Configures the controller clock source for a DS1 link. If the clock source is a network device attached to the T1/E1 port that you are configuring now, select the line option. For any other clock source (either internal or a network device attached to any other port), select the internal option. Note The IAD2435 IAD supports only two clock source options: internal clock source and line clock source. Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 Router(config-ctrl)# description line Router(config-ctrl)# cablelength short {133 | 266 | 399 | 533 | 655} or Router(config-ctrl)# cablelength long {gain26 | gain36} {-15db | -22.5db | -7.5db | 0db} Router(config-ctrl)# framing {sf | esf} Router(config-ctrl)# linecode {ami | b8zs} Router(config-ctrl)# no shutdown Router(config-ctrl)# exit Router(config)# exit Router# show controller t1/e1 1/0 Enters a description of the controller, such as the destination or its application. The description can be as many as 80 characters long. Configures the cable length if the length is 655 ft (200 m) or shorter. or Configures the receive gain and transmit attenuation if the cable length is longer than 655 ft (200 m). If necessary, changes the DS1 link framing format. The default is SuperFrame (sf). If necessary, changes the line encoding format for the DS1 link. The default is ami. Activates the T1/E1 controller. Exits controller configuration mode. Exits configuration mode. Verifies the controller configuration. Configuring Digital Voice To configure basic T1/E1 controller settings to support PPP, HDLC, or FR, follow these steps, beginning in global configuration mode: Step 1 Step 2 Step 3 Step 4 Step 5 Command Router(config)# controller t1/e1 1/0 Router(config-ctrl)# mode cas Router(config-ctrl)# framing esf Router(config-ctrl)# linecode b8zs Router(config-ctrl)# framing {sf | esf} Step 6 Router(config-ctrl)# ds0-group 1 timeslots 1-24 type e&m-immediate-start Description Enters controller configuration mode by controller number. Configures channel-associated signaling. Configures framing. Configures line encoding format. If necessary, changes the DS1 link framing format. The default is SuperFrame (sf). Configures the DS0 group. 32
