I have a situation where I'm trying to bring up three T1s across two VWIC-2MFT-T1-DI cards in built in WIC slots on a 2610. I can't get the serial int line protocol to ever come up, the MFR interface sees no LMI etc. But I can use two of the T1s on older WIC-1DSU cards and it comes up and runs like a champ. With the VWICs, the carrier sees slipping, but setting clock source line has no effect.
Anyone have any success with this? Command documentation for the "network-clock-participate" command indicates that the VWICs are limited to internal clocking unless this global command is used with the VWICs in an NM, which seems somewhat odd to me. Suggestions?
