asterisk users - Jan 2006 - red alarm?

Hi,

What is the meaning of:

Jan 17 18:05:21 WARNING[2388]: chan_zap.c:6315 handle_init_event: Detected alarm
on channel 2: Red Alarm
Jan 17 18:05:21 WARNING[2388]: chan_zap.c:1432 zt_disable_ec: Unable to disable
echo cancellation on channel 2
Jan 17 18:05:21 WARNING[2388]: chan_zap.c:6315 handle_init_event: Detected alarm
on channel 3: Red Alarm
Jan 17 18:05:21 WARNING[2388]: chan_zap.c:1432 zt_disable_ec: Unable to disable
echo cancellation on channel 3

This happened once today with my 30 channels, but then everything came back to
normal.

Thank you
Dov

Red alarm on PRI is a physical layer problem, as in your telco had an outage
or soemone unplugged the cable.
