[cisco-voip] BRI S/T to U interface convertor

[Eric Pedersen]

We bought a couple ISDN Link devices to connect BRIs to our Telepresence units. They take BRIs as 4-wire (S/T-interface), but from our service provider we get them as U interface (2 wires) ... seems like this is the standard in North America. Does anyone have recommendations for conversion units? Our old Polycom V/Cs have Alpha Telecom NT4 terminators. It looks like there are a few places that they can be ordered from but I don't know if they are new or used.

I'd rather get fractional PRIs for ISDN, but the SP said that PRIs are a voice service and BRIs are a data service - I assume that's a differentiation they make internally, not an ISDN limitation.

Thanks,
Eric
