Analog phones must be provided with a voltage that allows them to ring. The Analog Ring
Generator 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 a 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.
