Question: Has anyone connected a Cisco 15310-CL multiplexor to a T-1 smartjack? The 15310 has a 96-pin centronics like connector on the front that supports 21 DS0's. However, the other end of the cable that fits over that interface is a separate transmit/received pair of what appears to be 32 pins apiece. I have the map of the cable and have attempted to attached wires to a 66-block. No joy. Has anyone seen this device? Or better yet, has anyone connected it to a RJ-45 smartjack?
