[asterisk-users] Interfacing pri card to legacy pbx

[Nicolas Ross]

I cannot tell for sure for any system, but we have an old Portmaster PM3 
hooked-up from one port of our Sangoma A104d card, another one being from 
telco.

So, yes you can "emulate" the telco from a sangoma A10x card. Here's what I 
have in my zapata.conf :

;Sangoma A104 port 1 [slot:12 bus:0 span: 1]
switchtype=national
pridialplan=unknown
signalling=pri_cpe
group=1
channel => 1-23

;Sangoma A104 port 2 [slot:12 bus:0 span: 2]
echocancel=no
pridialplan=national
signalling=pri_net
group=2
channel => 25-47

You might have noticed that the signalling is different for both port. 
pri_net being the "telco emulatin" one. The clock needs also to be set on 
"master" in the wancfg utility.

Another thing, you might want to consider using a 2 port card for that, 
because the clock master needs a reference and I can't tell for sure if 
it'll work with a reference from another card.

Nicolas
