Terminating B1 lines from Voice Gateway

I will have a voice Gateway router as the endpoint for our DR site Voice DS3.

I am wondering about terminating some b1 lines from the carrier for FAX, modem and analog phones.

Can you simply put a NM-HDA module in the router with 8FXS ports, plug the amphinol connetion to the punch down block and punch doen the B1s for access?

I realize the router will have to be configured to do this as well, but is the concept feasable?

You would need FXO ports to terminate B1 lines. You would then need FXS ports, ATAs, or a VG224/248 to plug in the analog devices.

Hope this helps.

Re: Terminating B1 lines from Voice Gateway

Thanks for the reply.

The router I am thinking of doing this on is a 3845 that will be a voice gateway router.

Verizon will be terminating a DS3 to the router and routing our voice calls across the DS3.

What would plug into the FXO ports?

If Verizon is already terminating the voice trunk on the DS3, isn't all I need are the FXS ports?
