[Asterisk-Users] PRI concentrator

[Matthew Boehm]

Hey gang,
 We currently have a class 3 switch (CSX) that..well..it sucks. It does
terrible CDR writes, doesn't support LCR, the list goes on and on. We want
to replace this with several asterisk boxes each running one or two 4 port
PRI cards.
 The problem is: I can plug in 20 PRI lines into the CSX (from PSTN) and
have 1 come from CSX into asterisk. If 1 call comes in on each of the 20
pris, the CSX concentrates them into 1 pri into asterisk. Thus I only need a
single PRI card for asterisk box.

 If I want to completly replace the CSX, I would need several boxes with 1
or 2 4 port cards. But that is a big waste of money when I can concentrate
into less cables.

 Does anyone know of some piece of hardware (other than a carrier switch)
that will do the same thing? Keeping our current switch doesn't cost
anything except in terms of power consumption and physical space (its like
5U or 8U).

Thanks,
Matthew
