Configuring a Channelized T1 or E1 DFC
This section shows how to configure channelized T1 or E1. On a Cisco AS5350 or Cisco AS5400, 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 (CAS).
• 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 configure 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.

your application.
The CT1/E1 controller numbering convention is dfc-slot/port in CLI commands. DFC slot numbering starts from the
Note
motherboard and works up from left to right. Slot 0 is reserved for the motherboard. The CT1/E1 DFC slots are
numbered sequentially from 1 to 7. Port numbering is from 0 to 7.
Use the enable command and password to enter privileged EXEC mode. You are in privileged EXEC mode when the
Step 1
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# 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)#
Enter your telco's framing type for the CT1 controller, either esf or sf:
Step 4
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
.
Gateway(config)#
