Ringing in Series I peripherals 2-5

DMS-100 Family DMS-100 Ringing System BASE15 and up

Master processor

The LM and RLM master processor is the main processor. It contains the

software that performs the tasks requested by the DMS-100 CC. Under the

direction of the DMS-100 CC, the master processor directs the activities of the

subordinate processors in the LM and RLM.

Signal processor

The signal processor interfaces the master processor with the control units on

the line side of the LM or RLM, including the ringing generator interface.

SP and RGI interactions

The LM and RLM each contain one signal processor (SP) (NT2X25), one RGI

(NT2X27), and two ringing generators (NT2X05) in each bay; two SPs, two

RGIs, and four ringing generators in each unit. The signal processor and RGI

in each bay control the two ringing generators in their own bay. Crossover

circuits are provided between RGI cards in both bays to allow either SP/RGI

in one bay to take over the ringing generator in both bays if either SP or RGI

in either bay becomes inoperative. This conﬁguration is illustrated in the

following ﬁgure.

Figure 2-3 Normal ringing conﬁguration in LM/RLM

In normal operation, the signal processor and RGI in each bay control both

ringing generators in their own bay, RG 0 and RG 1. This conﬁguration is
