[Asterisk-Users] E1 problems

[Steve Underwood]

I think you have something backwards. PRI on E1 is great - 100% standard 
throughout the world, apart from some very old leftovers. Its the CAS 
stuff which needs endless new state machines. They really do need state 
machines. Write them in C, or do as we did (draw them graphically in 
Autocad, and compile them directly down to ROM tables). Either way you 
build a state machine.

Regards,
Steve
