[asterisk-r2] chan_dahdi.c: Detected alarm on channel 2: Red Alarm

[Vicky Noverto]

Hi,

I'm having problem with on and off red alarm on TE121. I'm using Trixbox
with E1 MFC/R2 implementation using philipine telco provider.
The alarm keep raise and clear in every 5-10 minutes on every channel. If
the alarm raise, all the call drop. Here is the output:

[Feb 24 17:30:26] DEBUG[4067] chan_dahdi.c: Chan 2 - Alarm Raised
[Feb 24 17:30:26] WARNING[4067] chan_dahdi.c: Detected alarm on channel 2:

and also from the log, i see this :
