To be master or not

I have a T1 point-to-point between the two sides. Each router 1760 has a WIC-1DSU-T1-V2. When I set both routers to slave mode - service-module t1 clock source line - ( which is wrong ) then the connection is up, and I can access the remote side, but the interface shows a high number of timing error.

When I set one router to master ( service-module t1 clock source internal ) then the connection is absolutely broken.

I called the telephone comany and they confirmed that my T1 is point-to-point and I must provide the clock from one router.

Could you please share some advice ?

Thanks,

DT
