we have two locations, which are connected to the central via an E1 line. On each of the three locations (2 subsidiaries and the central) we have an Cisco 2811 with VWIC2-1MFT on the subs and WIC2-2MFT on the central location.
For connecting the PBXs of the locations we need a dedicated leased line from our telco. My idea is to provide the leased line by ourselves via our E1 line.
Is this possible?
Can I install a BRI interface (which one) in the routers and cross connect the BRIs in the sub and the central?
How can this be done and how do I have to configure it?
At the moment we use the VWIC2-2MFT like this:
controller E1 0/0/0
channel-group 0 timeslots 1-31
My idea is to change channel-group 0 to timeslots 1-29 and use channel 30-31 for crossconnecting the BRIs.
How can this be done?
Thanks for your assistance and best regards
