Configuring E1 Interfaces; Configuring Tdm Connect (Data Pass-Through) - Cisco 2620 Configuration Manual

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.
Command
Step 1
Router> enable
Password: password
Router#
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Step 4
Router(config)# controller e1 1/0
Step 5
Router(config-controller)# framing crc4
Step 6
Router(config-controller)# linecode hdb3
Step 7
Router(config-controller)# channel-group 0
timeslots 1,3-5,7
Step 8
Router(config-controller)# interface
serial
1/0:0
Step 9
Router(config-if)# ip address 10.1.15.1
255.255.255.0
Step 10
Router(config-if)# appletalk static
cable-range 3-3
Router(config-if)# appletalk zone ZZEth
Router(config-if)# ipx network B005
Step 11
Router(config-if)# exit
Step 12
Router(config)# Ctrl-z

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.

Chapter 3 Configuring with the Command-Line Interface
Purpose
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to .
Router#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Select the CE1/PRI interface to configure. This
example configures an E1 interface in slot 1 and
unit 0.
Specify the framing type.
Specify the line code format.
Specify the channel group and time slots to be
mapped. For multiflex trunk interfaces, only
channel 0 can be configured.
Configure each channel group as a virtual serial
interface. Specify the E1 interface, unit number,
and channel group to modify.
Assign an IP address and subnet mask to the
interface.
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.
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.
When you finish configuring interfaces, return to
enable mode.
