Configuring a Channelized T3 Link
Router(config-controller)#
clock source line
•
Instruct the PA-MC-T3-EC to use an internal clock source.
The example that follows is for a port adapter in slot 1 of a Cisco 7200 VXR router:
Router(config)#
controller T3 1/0
Router(config-controller)#
clock source internal
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-T3-EC.
Note
MDL messages are only supported when the T3 framing is set for c-bit parity. (See the
“Setting the
Framing Type for the T3 Controller” section on page 5-10
.)
To configure MDL messages, use the
mdl {transmit {path | idle-signal | test-signal} | string {eic | lic
| fic | unit | pfi | port | generator}
string
}
controller commands where:
•
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).
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:
•
Enter controller configuration mode first.
The example that follows is for a port adapter in slot 1 of a Cisco 7200 VXR router:
Router#
configure terminal
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:
Router(config-controller)#
mdl transmit idle-signal
•
Enable the MDL test signal message transmission as follows:
Router(config-controller)#
mdl transmit test-signal
