Field Descri
p
tion
Bits received (since test started) Number of bits received since start of the BERT test.
Bit errors (since latest sync) Number of bit errors received since last synchronization.
Bits received (since latest sync) Number of bits received since last synchronization.
feac
Use feac to enable FEAC channel signal detection and sending on the CT3 interface.
Use undo feac to remove the current FEAC settings.
Syntax
feac { detect | generate { ds3-los | ds3-ais | ds3-oof | ds3-idle | ds3-eqptfail | loopback { ds3-line |
ds3-payload } } }
undo feac { detect | generate { ds3-los | ds3-ais | ds3-oof | ds3-idle | ds3-eqptfail | loopback
{ ds3-line | ds3-payload } } }
Default
Periodical FEAC channel signal detection is enabled.
Default
FEAC signal sending is disabled.
Default
Loopback code sending is disabled.

Default command level
2: System level
Parameters
detect: Enables periodical far end and control signal (FEAC) channel signal detection. generate: Sends
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 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 line test purposes, or to transmit loopback control code for activating or
deactivating far-end loopback during a loopback test.
According to ANSI T1.107a, the frame format used by FEAC channels is bit oriented protocol (BOP).
At the startup of your router, FEAC channel signal detection is enabled on the CT3 interface with FEAC
signal sending disabled.
After far-end loopback is activated with the feac generate loopback { ds3-line | ds3-payload } command,
you may remove it with the undo form of the command.
