Viking RG-4 1 Line Ring Shaper and Booster

The Viking RG-4 ring generator is designed to reshape and increase the ringing power of an existing telephone line, PABX extension, or any other telecom device which provides ringing. The RG-4 duplicates the incoming ring cadence allowing it to be compatible with custom ringing features. The RG-4 is capable of ringing four 1 REN or eight 0.5 REN telephones and does not affect normal operation of the telephone line or features provided by the phone company, such as caller ID and call waiting. The Viking model RG-10A may be used for higher drive output applications.
