Ringing in Series I peripherals 2-9

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

Ringing generator takeover and take back

Both ringing generators in each bay provide ringing signals for the lines in the

LM or RLM bay. The signal processor and RGI program the ringing generators

and, through the ring multiplexer, connect each ringing generator output to the

appropriate line. If either ring generator fails, the SP/RGI restricts ringing to

the alternate RG. The ringing system can still function in this conﬁguration.

However, the ringing capacity in the affected bay is reduced.

LM and RLM ringing generator parameters

The NT2X05 power converter +24 V card used in the LM or RLM as the

ringing generator has the following operating parameters:
