[Asterisk-Users] TE410P PRI T1 problem

[Dan Iordanescu]

Hello All,

I am doing the following E1 and T1 PRI tests. Two SIP phones and two
Asterisk boxes. Only one span is used in each case. See the test setup
explained below. The E1 PRI works well. The T1 PRI doesn't work; every
now and then (random time intervals) AsteriskA reports RedAlarm and
AsteriskB reports YellowAlarm. When alarms are reported the existing
calls get dropped.
Anybody has any ideas what is causing this?

SipPhoneA ----- AsteriskA(NTE) --pri-- (CPE)AsteriskB ----- SipPhoneB

The PRI link is configured as T1 for one test and as E1 for another
test. The zaptel.conf and zapata.conf for each box in each test is given
below:

AsteriskA(NTE) as T1
** zaptel.conf **
span=1,0,0,esf,b8zs
bchan=1-23
dchan=24
loadzone=us
defaultzone=us

** zapata.conf **
[channels]
context=default
switchtype=national
signalling=pri_net
group=1
channel=>1-23

AsteriskB(CPE) as T1
** zaptel.conf **
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
loadzone=us
defaultzone=us

** zapata.conf **

AsteriskA(NTE) as E1
** zaptel.conf **
