How to Commission the Cisco AS5850 Universal Gateway

Task 3. Configuring Channelized T1 or E1

This section shows how to configure channelized T1 or E1. You can allocate the available channels for

channelized E1 and T1 in the following ways:

• All channels can be configured to support ISDN PRI.

• If you are not running ISDN PRI, all channels can be configured to support robbed-bit signaling

(also known as channel-associated signaling).

• All channels can be configured in a single channel group.

• Mix and match channels supporting ISDN PRI, channel grouping, and channel-associated signaling.

• Mix and match channels supporting ISDN PRI, channel grouping, and robbed-bit signaling across

the same T1 line.

To configure a basic T1 or E1 controller, perform the following steps.

Step 1 Use the enable command and password to enter privileged EXEC mode. You are in privileged EXEC

mode when the prompt changes to Gateway#.

Gateway> enable

Password:

password

Gateway#

Step 2 Enter global configuration mode. You are in global configuration mode when the prompt changes to

Gateway(config)#.

Gateway# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Gateway(config)#

Step 3 Enter controller configuration mode to configure your controller slot and port. Slot values range from

0 to 5 and 8 to 13. Port values range from 0 to 23 for T1 and E1.

Gateway(config)# controller [t1 | e1]

slot/port

Gateway(config-controller)#

for the Sonet controller:

Router(config)# controller E1

slot

port.path:E1 contoller

Router(config-controller)#

Step 4 Enter your telco’s framing type for the CT1 controller: esf or sf.

Gateway(config-controller)# framing esf

or enter the framing type for the CE1 controller.

Gateway(config-controller)# framing crc4

Step 5 Define the line code as binary 8 zero substitution (B8ZS) for the CT1 controller.

Gateway(config-controller)# linecode b8zs

or define the line code as high-density bipolar 3 (HDB3) for the CE1 controller.

Gateway(config-controller)# linecode hdb3

Step 6 Return to privileged EXEC mode.

Gateway(config-controller)# Ctrl-Z

Gateway#
