Configuring a T1 or E1 Feature Card

This section shows how to configure a T1 or E1 feature card. On a Cisco AS5350XM or Cisco AS5400XM universal gateway,

you can allocate the available channels for channelized T1 and E1 in the following ways:

• You can configure all channels to support ISDN PRI.

• If you are not running ISDN PRI, you can configure all channels to support robbed-bit signaling (also known as

channel-associated signaling).

• You can configure all channels in a single channel group.

• You can configure mix and match channels supporting ISDN PRI, channel grouping, and channel-associated signaling

(CAS).

• You can configure mix and match channels supporting ISDN PRI, channel grouping, and robbed-bit signaling across the

same T1 line. For example, on the same channelized T1 you can use the pri-group timeslots 1-10,24 command,

channel-group 11 timeslots 11-16 command, and ds0-group 17 timeslots 17-23 type e&m-fgb command. This is an unusual

configuration because it requires you to align the correct range of time slots on both ends of the connection.

Note For configuration information about leased-line or nondial use, see the Cisco IOS Dial Technologies Configuration

Guide, available online. You can access this document at Technical Support & Documentation > Product Support >

Cisco IOS Software > Cisco IOS Software Release you are using > Configuration Guides.

Note The T1 and E1 controller numbering convention is slot/port in CLI commands. Feature card slot numbering starts from

the motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The CT1/E1 feature card slots

are numbered sequentially from 1 to 7. Port numbering is from 0 to 7.

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 1 to 7. Port

values range from 0 to 7 for T1 and E1.

Gateway(config)# controller [t1 | e1] slot/port

Gateway(config-controller)#

Step 4 Enter the telco framing type.

• For the CT1 controller, enter either esf or sf:

Gateway(config-controller)# framing esf

• For the CE1 controller, enter crc4:

Gateway(config-controller)# framing crc4
