Description & Operation

Privacy Switch has been designed to allow an OUTGOING ONLY telephone device to share an existing Voice, Fax or PBX line. This will save the installation and rental costs associated with operating a separate telephone line.

Privacy Switch will ensure that the PRIMARY DEVICE, such as a Fax Machine or PBX will be unaffected.

The Primary Device will continue to be able to Receive Calls and Make calls as normal.

The Accessory Device will only be able to make OUTGOING Calls when the telephone line is not in use.

An EXCLUSION FACILITY is provided to ensure that the attached devices cannot interfere (Barge-In) with each other, if the telephone line is in use. In this situation, the other device will not be able to access the line until it is free.




For EFT-POS users, a separate product is provided for using an EFT-POS device on an existing Voice, Fax or PBX line. Our EFT-POS Switch, which is supplied at the same price, has special modifications that are important for EFT-POS applications. Click for details here EFT-POS Switch
