Abstract:
1. An assembly for connecting telephone service equipment to a network side of a security monitoring system comprising: a telephone service interface (TSI) modular plug adapted for mating with a security monitoring system jack on a network interface device (NID), wherein a first side of the NID is connected to a telephone network and a second side of the NID is connected to an inside wiring system, wherein the NID comprises the security monitoring system jack and wherein the telephone network is connected to contacts four and five of the security monitoring system jack and wherein the inside wiring system is connected to contacts one and eight of the security monitoring system jack; a TSI jack, wherein the TSI jack is connected to the TSI modular plug via first and second conductors, wherein the first conductor establishes a first circuit between contact one on the TSI modular plug and contact one on the TSI jack, wherein the second conductor establishes a second circuit between contact eight on the TSI modular plug and contact eight on the TSI jack, wherein contact four and contact five of the TSI modular plug remain open and wherein when the TSI modular plug is mated with the security monitoring system jack on the NID, the inside wiring system is connected to contacts one and eight of the TSI modular plug and the TSI jack and wherein the telephone network is isolated from the TSI modular plug and the TSI jack; and first and second leads, wherein the first lead is connected to contact four of the TSI jack and the second lead is connected to contact five of the TSI jack, wherein when the TSI jack is mated with a security monitoring system connection plug from a security monitoring system, the first and second leads are connected to the network side of the security monitoring system via contacts four and five of the security monitoring system connection plug and to a telephone service equipment.
