PRIVACY DEVICE
Single Line Privacy
Model 41403 Line Guard
| The Proctor Model 41403 Line Guard privacy devices can be used in the home or office to give modem, FAX and other types of data transmission devices uninterrupted use of the phone line as soon as they access it. The modules can also be used to protect private telephones from eavesdropping and annoying interruptions and to assure the integrity of private telephone conversations.
How It Works
The 41403 is a balanced exclusion module that installs in series anywhere in the tip and ring path, or inside the telephone or wall jack to be restricted. Any data device or telephone equipped with a Line Guard will be
restricted from accessing a call already in progress; devices or phones not equipped with a privacy module will always have access to the line. The modules allow add-on conferencing between Line Guard equipped and/or non-equipped telephones with a simple hookswitch operation.
