Configuring T1 and E1 Interfaces Chapter 3 Configuring with the Command-Line Interface Configuring E1 Interfaces Use the following procedure to configure a new E1 or CE1/PRI interface (balanced or unbalanced) or to change the configuration of an existing interface. Command Purpose Step 1 Router> enable Enter enable mode. Enter the password. Password: password Router# You have entered enable mode when the prompt changes to Router#. Step 2 Router# configure terminal Enter global configuration mode. You have Enter configuration commands, one per line. entered global configuration mode when the End with CNTL/Z. prompt changes to Router(config)#. Router(config)# Step 3 Router# ip routing Router# appletalk routing Router# ipx routing Enable routing protocols as required for your global configuration. This example uses IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing. Step 4 Router(config)# controller e1 1/0 Select the CE1/PRI interface to configure. This example configures an E1 interface in slot 1 and unit 0. Step 5 Router(config-controller)# framing crc4 Specify the framing type. Step 6 Router(config-controller)# linecode hdb3 Specify the line code format. Step 7 Router(config-controller)# channel-group 0 Specify the channel group and time slots to be timeslots 1,3-5,7 mapped. For multiflex trunk interfaces, only channel 0 can be configured. Step 8 Router(config-controller)# interface serial 1/0:0 Configure each channel group as a virtual serial interface. Specify the E1 interface, unit number, and channel group to modify. Step 9 Router(config-if)# ip address 10.1.15.1 255.255.255.0 Assign an IP address and subnet mask to the interface. Step 10 Router(config-if)# appletalk static cable-range 3-3 Router(config-if)# appletalk zone ZZEth Router(config-if)# ipx network B005 Configure routing protocols on the interface. You must have previously enabled these protocols as part of global configuration. In this example, AppleTalk and IPX are being configured on the interface. Step 11 Router(config-if)# exit Exit back to global configuration mode. Step 12 Router(config)# Ctrl-z Return to Step 4 if your router has more than one CE1/PRI interface that you need to configure. When you finish configuring interfaces, return to enable mode. Configuring TDM Connect (Data Pass-Through) For multiflex trunk interfaces using the time-division multiplexing (TDM) connect function, you can use the connect command to connect two groups of DS0 timeslots from two controllers. 3-16 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04

Chapter 3
Configuring with the Command-Line Interface
Configuring T1 and E1 Interfaces
Configuring E1 Interfaces
Use the following procedure to configure a new E1 or CE1/PRI interface (balanced or unbalanced) or to
change the configuration of an existing interface.
Configuring TDM Connect (Data Pass-Through)
For multiflex trunk interfaces using the time-division multiplexing (TDM) connect function, you can use
the
connect
command to connect two groups of DS0 timeslots from two controllers.
Command
Purpose
Step 1
Router>
enable
Password:
password
Router#
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
Router#
.
Step 2
Router#
configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router#
ip routing
Router#
appletalk routing
Router#
ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 4
Router(config)#
controller e1 1/0
Select the CE1/PRI interface to configure. This
example configures an E1 interface in slot 1 and
unit 0.
Step 5
Router(config-controller)#
framing crc4
Specify the framing type.
Step 6
Router(config-controller)#
linecode hdb3
Specify the line code format.
Step 7
Router(config-controller)#
channel-group 0
timeslots 1,3-5,7
Specify the channel group and time slots to be
mapped. For multiflex trunk interfaces, only
channel 0 can be configured.
Step 8
Router(config-controller)#
interface
serial
1/0:0
Configure each channel group as a virtual serial
interface. Specify the E1 interface, unit number,
and channel group to modify.
Step 9
Router(config-if)#
ip address 10.1.15.1
255.255.255.0
Assign an IP address and subnet mask to the
interface.
Step 10
Router(config-if)#
appletalk static
cable-range 3-3
Router(config-if)#
appletalk zone ZZEth
Router(config-if)#
ipx network B005
Configure routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example,
AppleTalk and IPX are being configured on the
interface.
Step 11
Router(config-if)#
exit
Exit back to global configuration mode.
Return to Step 4 if your router has more than one
CE1/PRI interface that you need to configure.
Step 12
Router(config)#
Ctrl-z
When you finish configuring interfaces, return to
enable mode.
