[c-nsp] PRI to BRI Conversion with Cisco IAD

[Chris Taylor]

Working on my first video teleconferencing project.

 

Problem:

                Equipment I inherited; Polycom VSX 7000 with a BRI Interface
needs to interface and call out over a 3 Channel PRI ISDN Circuit.  Also
received a NT384 device (U Interface)  that doesn't seem to work over the
PRI circuit.

 

Is there a configuration that could be used with following IAD 2431 to
perhaps mux down the PRI channels to hand off a BRI interface to my VTC unit
(Polycom VSX 7000)
