Can I run a long distance leased line between two routers with VWIC-2MFT-G703 and VWIC-2MFT-T1 interfaces?
No, VWIC-2MFT-G703 can be used for E1 only:
Please refer to:
However, for intercontinental leased lines, you can have situations in which the circuit is T1 on one side, and E1 w/ 24 timeslots on the other, so the answer to the original question would be yes for that particulal case. Note again that to terminate such frame circuit the more expensive VWIC-2MFT-G703 would not be necessary, as a simple VWIC-xMFT-E1 would be enough.
Hope this helps, please rate post if it does!
