Verifying Controller Configuration

Use the show controllers command to verify the controller configuration:
Router(config)# show controllers e1 0/3/0 brief
E1 0/3/0 is up.

Purpose
Selects the framing type.
• sf—Specifies Super Frame as the T1 frame type.
• esf—Specifies Extended Super Frame as the T1 frame type. This is the default
for E1.
• crc4—Specifies CRC4 as the E1 frame type. This is the default for E1.
• no-crc4—Specifies no CRC4 as the E1 frame type.
Defines the time slots that belong to each T1 or E1 circuit.
• t1 t1-number— Channel-group number. When configuring a T1 data line,
channel-group numbers can be values from 0 to 23. When configuring an E1 data
line, channel-group numbers can be values from 0 to 30.
• timeslots range— One or more time slots or ranges of time slots belonging to the
channel group. The first time slot is numbered 1. For a T1 controller, the time
slot range is from 1 to 24. For an E1 controller, the time slot range is from 1 to
31.
• unframed—Unframed mode (G.703) uses all 32 time slots for data. None of the
32 time slots are used for framing signals.
• speed—(Optional) Specifies the speed of the underlying DS0s in kilobits per
second. Valid values are 56 and 64.
The default is 64. Speed is not mentioned in the
Note
configuration.
Note Each channel group is presented to the system as a serial interface that can be
configured individually.
Once a channel group has been created with the channel-group command, the
Note
channel group cannot be changed without removing the channel group. To
remove a channel group, see the
on page 233.
Exits configuration mode and returns to the EXEC command interpreter prompt.
