Connecting a PBX tie line to a Cisco Router

    Hi, I rolled a hub site from a PBX to cisco voip solution. The PBX had a tie line to 5 remote PBX's via a Newbridge mux which split channels on the point-to-point T1's to each site into some data channels and some voice channels.

    I still have the newbridge in the picture. The data channels are connected to a old school serial interface and working good to each remote site.

    We took the PBX at the hub site off line, so the voice channels coming from each remote site that are mux together that used to goes to the PBX, now goes to an MFT port on the router.

    I've tried various E&M sig type and can't get the port out of alarm mode. I thought I had a cabling issue so I tried cat5, rolled cable, cross over then found the orginal PBX cables. Using those gets me a CD light.

    Does anyone have experience in this scenario?
    Thanks, Geo
