Can we configure E1 links with no G.704 framing using the VWIC2-2MFT-T1/E1 (desc: 2-Port 2nd Gen Multiflex Trunk Voice/WAN Int. Card - T1/E1), as follows:
card type e1 0 0
controller E1 0/0/0
channel-group 0 unframed
I have a Cisco 2821 ISR installed with this VWIC but the above "unframed" keyword is not available.
Referring to URL below,
Table 2 outlines that VWIC2-2MFT-T1/E1 does not support Unstructured E1/G.703.
Does it mean it does not support E1 link with no G.704 framing?
