Due to a lot of restrictions, we can't share our data network with voice, and we only have analog phones now. Another limitation we have now is we only have a single Ethernet drop for each office. A phone company mentioned that they will bring in their own T-1, so they don't have to use our existing T-1 (for data only) and can still use the only existing Ethernet drop to route traffic out to different T-1 lines, by plugging in the computers to the back of the phone. My question is... is it even possible to separate the traffic so they go through different T-1 lines by using the same Ethernet drop? How can I be sure that the voice and data networks do not bleed into each other? Please advise. Thanks much!
