Ringing
Generators
Two CPS ringing generators installed in a single-shelf
plant provide redundant ringing power. Two-shelf
plants offer additional ringing capacity with up to two
ringing generators in each shelf.
Two ringers are installed in the shelf first beginning in
Slot 1, then rectifiers are installed beginning in Slot 2,
installing from left to right. Note: If ringers are not
installed, rectifiers are installed beginning in Slot 1.
The ringers feature ROM-based wave form generation
typical of Lucent Technologies Type-3 Ringing
Generators. CPS ringers feature a unique self-contained
ring switch unit that automatically detects a failed
ringing generator and switches the on-line spare into
active service.
Ringing output is provided on the shelf from the secondary bus output
connector J14. The ring signal cadencing and tripping device must be
provided by the end-use product.
Table 2-A provides information about the ringing power of the ringing
generators.
