I removed my ADT Commander 2000 panel, phones dead. Where can I find ADT wiring Diagram? Three wires remain.?

There were 3 wires coming to box. Two normal phone wires (yellow, black, green, red) and one with 9 wires (blue, yellow, red, black, brown, orange, white, purple and green.) This system has not been in use. I traced the wires into attic and they disapear into wall. I can not trace them back to main phone panel in garage. How can I splice these to get phones up? I tried to hook the 4-wire lines together by color with no luck.
My phone is provided by comcast modem with phone line tied into nearest jack that feeds house. We have one line. Please help!
So you mean run another wire form teh demark and splice it in with the two 4-wire lines? What is the 9 wire line??
