The Com-Power RS 368 Ringer Set is capable of supplying the ringer voltage for the On Hook impedance and billing protection testing.
The RS-368 on-hook impedance measurements evaluate if the telephone equipment being tested could harm the public switched telephone network or impair service when connected. The billing delay measurement checks telephone equipment to make sure that it does not disrupt the ability of the phone company to bill for services.
The RS-368 Ringer signal frequency can be adjusted from 15 Hz - 70 Hz. The voltage can be adjusted between 0 and 175 VAC.
