Viking's Teleguard Automatic Privacy Devices

Prevent your phone calls or fax/modem transmissions from being interrupted if someone accidentally picks up another extension. Teleguard also protects against eavesdroppers.

With Viking's Teleguard, whichever device accesses the C.O. or PABX line first denies any other teleguard-equipped device access to the line until the call in progress is terminated.

Incoming calls will ring into all devices simulataneously. The device that answers first denies any other teleguard-equipped device access.

Any telecom device not equipped with Teleguard can always break into a phone call or transmission.
