[Asterisk-Users] Is there a product to simulate a PRI trunk?

[Dey, Spondon, ALABS]

Charlie,
I appreciate the clarification on the cross over..... 
I haven't tried this yet but I do understand that in theory it should
work..... 
Glad to hear confirmation that this does work though.....
Thanks!!
Spondon

That is incorrect, you need a crossover cable to go directly between two
T1 jacks if the Telco isn't in the middle. A T1/E1 crossover cable swaps
pins 1&2 with 4&5.

For PRI, configure one end as pri_net, and the other end as pri_cpe.

Works just fine. Lots and lots of folks do this. Channel banks, legacy
phone systems, multiple asterisk systems, modem servers.
