Configuring the Channelized DS3 Frame Relay Port Adapter

Configuring the T1 Lines on the CDS3 Frame Relay Port Adapter

To configure the T1 lines, perform the following steps, beginning in global configuration mode:
Command
Step 1
Switch(config)# controller t3 card/subcard/port
Switch(config-controller)#
Step 2 Switch(config-controller)# t1 line-number
framing {esf | sf}
Step 3 Switch(config-controller)# t1 line-number yellow
{detection | generation}

Configuring the Channel Group on the CDS3 Frame Relay Port Adapter

A channel group, also referred to as a serial interface, is configured on a T1 line by associating time slots
to it. The channel group can have from 1 to 24 time slots (DS0s). The transmission rate or bandwidth of
the channel group is calculated by multiplying the number of time slots times 56 kbps or 64 kbps.
A time slot can be part of only one channel group. Additionally, all time slots within a channel group
Note
must be on the same T1 line.
To configure the channel group on a T1 line, perform the following steps, beginning in global
configuration mode:
Command
Step 1
Switch(config)# controller t3 card/subcard/port
Step 2 Switch(config-controller)# channel-group
number t1 line-number
timeslots list [speed {56 | 64}]
You can group either contiguous or noncontiguous time slots on a T1 line.
Note
Example
The following example shows how to configure a channel group (with identifier 5), assigning time slots
1 through 5 on T1 line 1 using the channel-group command.
Switch(config)# controller t3 0/1/0
Switch(config-controller)# channel-group 5 t1 1 timeslots 1-5
Switch(config-controller)#
The example above creates the serial interface 0/1/0:5.
