Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+
Configuring a Channelized T3 Link
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router(config)#
controller T3 1/0
Router(config-controller)#
t1 1 channel-group 20 timeslots 1-5, 20-23
Note
Each T1 link may have up to 24 channel groups with an overall limit of 128 for the 28 T1 links on each
T3 port. Unused channel groups in one T3 port may not be used by the other T3 port.
Note
Each channel group defined with this command causes a serial interface to be created. Refer to the
“Performing a Basic Serial Interface Configuration” section on page 5-24
for instructions on configuring
these interfaces.
Note
All the encapsulation formats, such as PPP, HDLC, SMDS, Frame Relay, and switching types are
applicable to the serial interface and can be set using the serial interface configuration commands.
Removing a Logical Channel Group from a T1 Line
You can remove a logical channel group from a T1 line with the following controller command:
no t1
t1-line-number
channel-group
channel-group-number
where:
•
t1-line-number
is 1–28.
•
channel-group-number
is 0–23.
Remove logical channel group 10 from channelized T1 line 1.
The example that follows is for a port adapter on a VIP in interface processor slot 1:
Router(config)#
controller T3 1/0/0
Router(config-controller)#
no t1 1 channel-group 10
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router(config)#
controller T3 1/0
Router(config-controller)#
no t1 1 channel-group 10
Note
If logical channel groups had previously been configured on a port, and you switch to ‘no channelized’
mode, first remove all channel groups before invoking the ‘no channelized’ command.
Setting the Framing Format on a T1 Line
You can specify the T1 framing format using the controller command:
t1
t1-line-number
framing
{
esf
|
sf
}
where:
•
The default framing format is extended super frame (ESF).
•
t1-line-number
is 1–28.
Examples follow:
•
Set Super Frame (SF) framing format for T1 line 6.
