1 Line Ring Shaper/Booster

The RG-4 ring generator is designed to reshape and increase the ringing power of an existing analog line, PABX extension, FXS port, IP phone system analog port 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. For multi-line applications, use Viking models RG-204 (4 line), RG-212 (12 line) or RG-224 (24 line). The Viking model RG10A may be used for single line higher drive output applications up to 12 REN.
