Configuring a T1/E1 Port for a WAN Connection

The T1/E1 port supports balanced T1/E1 according to ANSI T1.403 and has a built-in CSU/DSU.
To configure basic T1/E1 controller settings to support Point-to-Poing Protocol (PPP), High-Level Data
Link Control (HDLC), or Frame Relay (FR), follow these steps, beginning in global configuration mode:
Command
Step 1
Router(config)# controller T1/E1 1/0
Step 2
Router(config-ctrl)# clock source {internal | line |
loop-timed}
Step 3
Router(config-ctrl)# description line
Step 4
Router(config-ctrl)# cablelength short {133 | 266 |
399 | 533 | 655}
or
Router(config-ctrl)# cablelength long {gain26 |
gain36} {-15db | -22.5db | -7.5db | 0db}
Step 5
Router(config-ctrl)# framing {sf | esf}
Step 6
Router(config-ctrl)# linecode {ami | b8zs}
OL-4234-06
Purpose
Enters global configuration mode.
Sets a password for the privileged EXEC mode.
Enters interface configuration mode.
Enters the IP address and subnet mask for the Fast
Ethernet (10/100BASE-T) port.
Activates the 10/100BASE-T port.
Returns to global configuration mode.
Enters line configuration mode.
Sets a password for remote access to the Cisco IAD.
Returns to privileged EXEC mode.
Saves the configuration.
Purpose
Enters controller configuration mode by controller
number. Slot and port numbers vary.
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 (internal
or a network device attached to any other port),
select the internal option.
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.
