Configuring Channelized mode for the Cisco PA-MC-2T3+
Configuring MDL Messages for the T3 Controller
You can configure Maintenance Data Link (MDL) messages (which are defined in the
ANSI T1.107a-1990 specification) on the PA-MC-2T3+.
Note
MDL messages are only supported when the T3 framing is set for c-bit parity. (See the
Framing Type for the T3 Controller" section on page
To configure MDL messages, use the controller commands:
where:
•
•
•
•
•
•
•
Use the no form of this command to remove MDL messages. The default is that no MDL message is
configured.
Examples of MDL Message Configuration
Examples of configuring MDL messages follow:
•
•
•
OL-3526-05
mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator}
string
}
no mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port |
generator} string
}
eic is the equipment identification code (up to 10 characters).
lic is the location identification code (up to 11 characters).
fic is the frame identification code (up to 10 characters).
unit is the unit identification code (up to 6 characters).
pfi is the facility identification code to send in the MDL path message (up to 38 characters).
port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message
(up to 38 characters).
generator is the generator number to send in the MDL test signal message (up to 38 characters).
Enter controller configuration mode first.
The example that follows is for a port adapter on a VIP in interface processor slot 1:
Router# configure t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/0/0
Router(config-controller)#
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router# configure t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller T3 1/0
Router(config-controller)#
Enable the MDL path message transmission as follows:
Router(config-controller)# mdl transmit path
Enable the MDL idle signal message transmission as follows:
5-5.)
