This may be interesting: to configure the NT1 Plus, I use a tone phone.
While in configuration mode, I hear a "click" sound every 30 seconds:
exactly when Asterisk logs the [PRI got event: HDLC Abort (6) on D-channel
of span 1]. So it's something coming from the local NT or even from the
TELCO. They say there are no issues on the line, so maybe it's the NT. The
"click" is every 30 seconds, not at random. Should wcb4xxp handle this? Why
is it going to Red Alarm? If I unload wcb4xxp, the NT stays up, so it's
wcb4xxp to hang it down.
