path ds3 mdl carrier
Use the no version to restart a disabled interface.
See path ds3 shutdown.
Use to enable SNMP link status processing for a T3 interface.
The default disables SNMP link status processing.
Example
host1(config-controll)#path 12 ds3 1 snmp trap link-status
Use the no version to disable SNMP link status processing.
See path ds3 snmp trap link-status.
Specify a SONET interface.
host1(config)#controller sonet 8/0
(Optional) Configure the interface to operate in an MDL carrier environment.
host1(config-controll)#path 12 ds3 1 mdl carrier
Specify the MDL messages.
host1(config-controll)#path 12 ds3 1 mdl string eic "ERX 1410"
host1(config-controll)#path 12 ds3 1 mdl string fic "FG786"
host1(config-controll)#path 12 ds3 1 mdl string lic "Bldg 2"
host1(config-controll)#path 12 ds3 1 mdl string pfi "Site 1"
host1(config-controll)#path 12 ds3 1 mdl string port 0800
host1(config-controll)#path 12 ds3 1 mdl string unit 080001
Enable transmissions of MDL messages.
host1(config-controll)#path 12 ds3 1 mdl transmit path-id
host1(config-controll)#path 12 ds3 1 mdl transmit idle-signal
host1(config-controll)#path 12 ds3 1 mdl transmit test-signal
