Ringing in Series II peripherals 3-17

DMS-100 Ringing System

Detailed ringing schematic

The schematic in theFigure 3-6, "Detailed ringing schematic" on page 3-18

shows the signal path from the ringing generators to the line drawers located

in both units of the LCM. This signal path includes the NT6X53AA power

converters in both LCM units and the NT6X54AA BICs in the line drawers.

The schematic shows ringing generator outputs to only one LCM for clarity;

the outputs shown in this ﬁgure connect to both LCMs in the LCE. Also, only

two BICs are shown in the schematic; however, the connections are actually

made to the BIC in each of the 10 line drawers in the LCM.

As illustrated by the detailed schematic, the ringing generator provides two

important functions. The ringing generator generates both ringing signals and

ANI/coin signals. These functions are described next.
