Configure the clock mode of a T3 channel the same as the global clock mode.
Examples
# Configure the clock mode as master for the T3 channel 3 on CPOS 2/0/0.

[Sysname] controller cpos 2/0/0
[Sysname-Cpos2/0/0] t3 3 set clock master
t3 set feac
Use t3 set feac to enable FEAC channel signal detection or FEAC signal sending on the specified T3
interface.
Use undo t3 set feac to remove the current FEAC settings.
Syntax
t3 t3-number set feac { detect | generate { ds3-los | ds3-ais | ds3-oof | ds3-idle | ds3-eqptfail |
loopback { ds3-line | ds3-payload } } }
undo t3 t3-number set feac { detect | generate { ds3-los | ds3-ais | ds3-oof | ds3-idle | ds3-eqptfail |
loopback { ds3-line | ds3-payload } } }
Default
Periodical FEAC signal detection is enabled.
Default
FEAC signal sending is disabled.
Default
Loopback code sending is disabled.
Default
FEAC signal detection and sending are disabled on a T3 channel.

Parameters
t3-number: Number of a T3 channel on the current CPOS interface, in the range of 1 to 3.
detect: Enables periodical far end alarm and control (FEAC) signal detection on the specified T3 channel.
generate: Generates and sends a specific type of FEAC signals. Specify ds3-los for DS3 LOS, ds3-ais for
DS3 AIS, ds3-oof for DS3 out of frame (OOF), ds3-idle for DS3 idle, and ds3-eqptfail for DS3 equipment
failure.
loopback: Sends a specific type of loopback code for activating far-end line loopback with the ds3-line
keyword or payload loopback with the ds3-payload keyword.
Usage guidelines
FEAC is a channel formed by using the third C-bit in the first subframe in C-bit framing. It is used to
transmit alarm state signals for the line test purposes, or to transmit loopback control code for activating
or deactivating far-end loopback during a loopback test.
