Usage Guidelines
The FXOLS voice port is in the busyout state if the Digital Signal Processor (DSP) detects that no cable is connected between the analog FXSLS and FXOLS ports. If you have configured the no cable-detect command and the analog FXOLS voice port is in busyout state because no cable is connected, the Cisco software stops polling the cable connection. The analog FXOLS voice port remains in the busyout state until you use the shutdown and no shutdown commands to switch the analog FXOLS voice port to the idle state. The cable-detect command supports loop start and Central Automatic Message Accounting (CAMA) signaling.
Unlike FXOLS, for analog FXOGS, FXSLS, and FXSGS voice ports, the voice port state does not change when the cable status changes from connected to disconnected or disconnected to connected; only a syslog message is printed to indicate the new cable status. The cable-detect command will not show up under the voice port if the analog voice interface does not support cable polling.
For analog FXOGS, the cable-detect command can be configured on all FXO voice interface cards.
This command can be configured on the following analog FXOLS voice interface cards (VICs):
-
VIC2-2FXS
-
VIC2-4FXS
-
EM-HDA-6FXO
-

For analog FXSLS and FXSGS, this command can be configured on the following FXS voice interface cards:
-

-
VIC3-4FXS/DID
-
VIC3-2FXS-E/DID
-
EM3-HDA-8FXS/DID
-

-
SM-D-48FXS-E
-
Onboard analog FXS on Cisco 8xx platforms
-
Onboard analog FXS on Cisco VG20x and VG2435 platforms
