Initial Configuration Procedures
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 Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# enable password
password
Sets a password for the privileged EXEC mode.
Step 3
Router(config)# interface FastEthernet 0/0
Enters interface configuration mode.
Step 4
Router(config-if)# ip address
IP-address subnet-mask
Enters the IP address and subnet mask for the Fast
Ethernet (10/100BASE-T) port.
Step 5
Router(config-if)# no shutdown
Activates the 10/100BASE-T port.
Step 6
Router(config-if)# exit
Returns to global configuration mode.
Step 7
Router(config)# line vty 0 4
Enters line configuration mode.
Step 8
Router(config-line)# password
password
Sets a password for remote access to the Cisco IAD.
Step 9
Router(config-line)# end
Returns to privileged EXEC mode.
Step 10
Router# copy system:running-config nvram:
startup-config
Saves the configuration.
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)# clock source {internal | line |
loop-timed}
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.
Step 3
Router(config-ctrl)# description
line
Enters a description of the controller, such as the
destination or its application. The description can be
as many as 80 characters long.
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}
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).
Step 5
Router(config-ctrl)# framing {sf | esf}
If necessary, changes the DS1 link framing format.
The default is SuperFrame (sf).
Step 6
Router(config-ctrl)# linecode {ami | b8zs}
If necessary, changes the line encoding format for
the DS1 link. The default is ami.
