You need a C6 module, and service from the carrier. Connect line one to the W/Bl pair on the amphenol off the C6. Then from the W/Bl pair (yes, straight through)continue to the phone system. DO this for each line, W/O pair is line two, W/Gr is line three..
Customer will have to use Feature 811 (caller ID inspect to view prior to picking up the line. Only prime set will display info with nothing further to do.
