Max Ringers (Route: SFE,2)
The maximum number of SLTs which can be fed ring generators simultaneously from
each PS19 DC-D is 33. By default, however, its value in the Coral database is set to
20. This default value can be altered via the Coral PI database’s System Features
(
Route: SFE,2
) branch, by changing the system-wide MAX_RING parameter value.
See Chapter 6 of the Program Interface and Database Reference Manual for further
details.
Defining Ringer Shelf Number (Route: RPS)
The ringer power supply (RINGER PS) definition in the PI database of the RPS branch
must be defined to reflect the actual power supply hardware setup per cage. The
(RINGER PS) default definitions are set up for Double Power configurations. For the
Economical and Redundant Power configurations, the RINGER PS definition per
cage must be updated to reflect the actual system setup - especially when increasing
MAX_RING.
When a PS19 DC-D supplies power to SLT ringers located on two adjacent cages
( Redundant or Economical configurations), the two adjacent cages must share the
same RINGER PS definition, via the Coral database
(Route: RPS)
.
See Chapter 6 — Ringers , of the Coral Program Interface & Database Reference
Manual for details on the parameter definitions.
