Hi,
I have an asterisk box with a sangoma a102 (two PRI ports).
Is is possible to connect port A to port B in order to use port B as a
simulation of a telco PRI line?
If yes, is there a special cable needed? How can I configure the card
and zaptel.conf?
Yes. You'll need a T1 crossover cable to do it. Google for which pins to
swap.
Configure one port as pri_net (acts as a central office switch) and the
other port as pri_cpe (acts as a pbx). See the sample configs for other
parameters (including /etc/zaptel.conf timing parameters).
Your zapata.conf entries will look something like these:
resetinterval=never ; gets rid of the many restart messages
context=pri-in
signalling=pri_net
switchtype=national
pridialplan=unknown
channel=>1-23
context=pri-out
switchtype=national
signalling=pri_cpe
pridailplan=unknown
group=7
channel=>25-47
And, /etc/zaptel.conf something like this:
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
span=2,0,0,esf,b8zs
bchan=25-47
dchan=48
