Configuring multiple Data T1s on NM-2W w/ VWIC-2MFT-T1

I am trying to get four (4) T1s running between a C3660 and C3640. Each router has a NM-2W and two (2) VWIC-2MFT-T1. So far, I have done the controller configs (setup framing, line coding and timeslots). This has created the associated Serial interfaces. Running Cisco default HDLC. At first, I left the clocking to the default, line, and could not get data to pass. Noticed that all for controllers on the NM-2W module use the same primary clock source. Carrier (AT&T and Verizon) say that they are NOT providing clock, so I set one side to internal clock and left the other side to line and this did not help.

Has anyone done this before?

TIA

Randy

What kind of circuit ? At one time local carriers would sell Local area data service that had no timiming, is that what you got ?
