Required Configuration Tasks
Setting the Card Type
The interface module is not functional until the card type is set. Information about the interface module
is not indicated in the output of any show commands until the card type has been set. There is no default
card type.
Note
Mixing of interface types is not supported. All ports on the interface module must be of the same type.
To set the card type for the T1/E1 interface module, complete these steps:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# card type {e1 | t1}0 1
Step 3
Router(config)# exit
Enabling the Interfaces on the Controller
To create the interfaces for the T1/E1 interface module, complete these steps:
Command
Step 1
Router(config)# controller {t1 | e1}
0/number
Step 2
Router(config-controller)# clock source
{internal | line}

Chapter 2
Purpose
Enters global configuration mode.
Sets the serial mode for the interface module:
•
t1—Specifies T1 connectivity of 1.536 Mbps.
B8ZS is the default line code for T1.
•
e1—Specifies a wide-area digital transmission
scheme used predominantly in Europe that
carries data at a rate of 1.984 Mbps in framed
mode and 2.048 Mbps in unframed E1 mode.
Exits configuration mode and returns to the EXEC
command interpreter prompt.
Purpose
Selects the controller to configure and enters controller
configuration mode.
•
t1—Specifies the T1 controller.
•
e1—Specifies the E1 controller.
•
number—Specifies the location of the controller.
The number range for T1 and E1 is 1 to 16.
Sets the clock source.
The clock source is set to internal if the opposite
Note
end of the connection is set to line and the clock
source is set to line if the opposite end of the
connection is set to internal.
•
internal—Specifies that the internal clock source is
used.
•
line—Specifies that the network clock source is
used. This is the default for T1 and E1.
