RING-GEN
Analog Ring Generator
Analog phones must be provided with a voltage that allows them to ring. The
Analog Ring Generator MO represents the device that provides the ringing
voltage for every analog phone associated with a given cabinet. In a multicarrier
cabinet, the ring generator resides in the power distribution unit. It is protected by
a fuse located next to the main circuit breaker on the front of the unit. In
single-carrier cabinets, the ring generator is part of the WP-91153 power supply.
Failure of the ring generator results in loss of ringing on analog phones. Ringing
on digital and hybrid phones is not affected.
The ringing voltage is monitored by the Tone-Clock circuit pack. In a port network
with duplicated Tone-Clocks, the active Tone-Clock performs this function. In an
PN made up of single-carrier cabinets, the Tone-Clock monitors the ringing
voltage of only the carrier where it resides.
The TN2036 Voltage Range circuit pack provides easy access for testing the
various voltages on the backplane pins. For more information, see
