Multiway Telephone Device Circuit Deisgn

I have 10 phone lines coming in to office with

an extension on each leading in to a patch panel in a seperate room

I need a cicuit diagram for the following:

10 modem shaped sockets for the lines to plug into modem type so only 2 wires used (patch leads will be used)

the board is to monitor the 10 lines and display a green led if the line is not being used and display a red led if the line is engaged.

if the line is free then the board will open it up for use.

The 10 lines go to 2no [url removed, login to view] head phone jacks, one for MIC and one for speaker. Only the lines that were not in use when the board is powered up will route through to the jacks, the others will remain uninterrupted. Ideally this is to be run on 9-12v.

see attached a basic look of the board without techincal detail whatsoever. If you can provide a PCB layour schematic and/or a full working PCB of this aswell let me know BUT DO NOT include this with your bid, this shall be taken out at a later date. ONLY quote for the circuit design.

Must be contactable via msn
