the company i work for has to change its WAN infrastructure. Our provider (Deutsche Telekom AG) provides us 2 Mbit/s lines to all our locations in Germany and these lines are E1 with unstructured G.703.
Alternatively we had the possibility to chosse G.703 with G.704 framing, but we choose unstructured G.703.
I got these lines working with the VWIC2-1MFT interfaces. Cisco also offers the VWIC2-1MFT-G703 interfaces.
My opinion was, that for the unstructured G.703-leased lines, I need the VWIC2-1MFT-G703 interface, but the normal and cheaper VWIC2-1MFT also work.
I am happy about this, but i am wondering, for what I would need the -G703 interfaces?
Can anybody tell me the difference?
The normal VWIC2-1MFt seems also to with unstructured G.703 (E1). For what would I need the G703-interfaces?
Thanks for all information and best regards,
