[asterisk-users] TE405P intermittent yellow alarm
Folks, I really hope you can help me here - I'm beginning to tear my hair out! About 10 days ago my company moved to a new office. As a result of this, we've plugged our PBX box, which has happily been running for the last three years, into our new E1 line. Since then, I've been seeing intermittent yellow alarms. Obviously, since this was working fine in the old office, the thing to suspect is the new line - but the telco (British Telecom) aren't really helping much. The box is a 2.4GHz Intel box, with a TE405P installed in it (we're only using one of the spans). I'm using the zaptel drivers version 1.4.4 (I've also tried 1.0.2 with similar results). zaptel.conf has: span=1,1,0,ccs,hdb3,crc4 bchan=1-15,17-31 dchan=16 Essentially it runs fine for a few hours; then zttool reports yellow alarm and calls can be made neither in nor out. After a while this clears itself again and all is well for another few hours. At this point, I'd really like to know what a yellow alarm actually means. I've read that it indicates that that the other end of the E1 is in an alarm condition: however BT's terminating unit seems quite happy with no alarm conditions at all. So, really hoping that someone can shed some light on what this might all mean.

Replace it with new stuff. Re-punch everything. It is obviously somewhere in the line. If the above does not fix it, maybe you can get a lucky and get a good tech out that will stick around to see the issue. Thanks, Steve
