I have a Cisco 3640 router with a NM-HDV and VWIC-2MFT-E1-DI, interface
that was used for a VoIP link that is no longer used.
I would like to use this hardware to connect a WAN data link that came
to me with a G.703 interface but I'm having troble to configure.
I'm setting using this:
channel-group e1 timeslots 1-31
I use the IOS 12.1(5)T7
Is there any document that can halp me, since I don't have the interface
