host1(config-controll)#path 12 ds3 1 mdl transmit idle-signal
host1(config-controll)#path 12 ds3 1 mdl transmit test-signal
Use to specify that an interface is used in the carrier environment.
Example
host1(config-controll)#path 12 ds3 1 mdl carrier
Use the no version to restore the default situation, in which the interface does not
operate in the carrier environment.
See path ds3 mdl carrier.
Use to specify an MDL message.
Example
host1(config-controll)#path 12 ds3 1 mdl string port 0800
Use the no version to restore the default value to the specified MDL message or to all
MDL messages.
See path ds3 mdl string.
Use to enable transmission of MDL messages.
Specify the keyword path-id to transmit path identifications every second.
Specify the keyword idle-signal to send idle signals every second.
Specify the keyword test-signal to transmit test signals every second.
Example
host1(config-controll)#path 12 ds3 1 mdl transmit test-signal
Use the no version to disable transmission of the specified type of MDL messages or
all MDL messages.
See path ds3 mdl transmit.

Configuring T1 Channels on T3 Interfaces

To configure T1 and fractional T1 channels over T3 interfaces:
Configure the T1 path.
1.
Configure the clock source.
2.
You must coordinate this setting with the other end of the line to establish which
end is the transmit (internal) clock and which is the receive (line) clock.
(Optional) Assign a text description or an alias to the interface.
3.
(Optional) Configure the framing format.
4.
