The Proctor Model 41434 Line Guard can be used in the home or office to give computer, facsimile and other types of data transmission devices uninterrupted use of the phone line once they access it. The module can also be used to protect telephones from eavesdropping and annoying interruptions.
How It Works
The 41434 Line Guard installs in series with the Central Office (C.O.) line, splitting it into two separate extension lines marked "Port 1" and "Port 2". Whichever port is used to dial out or answer a call first is given exclusive use of the C.O. line; the other port is prevented from accessing the line until the first port's call is terminated and the C.O. line is clear. Line ports "1" and "2" work with either voice or data devices and each port can serve multiple station devices . A balanced cutoff is provided on each port to provide maximum line privacy.
Typical Data Application

Each line port ("1" or "2") can serve multiple data or voice devices (the 41434 does not provide exclusivity between stations sharing the same port).
Easy to install; standard modular connectors are provided for the C.O. line and two extension ports.
Operates on telephone line current; does not require any external power source.
The modules do not affect transmission, signaling, or pulsing characteristics of the line.
