Two CPS ringing generators installed in a single-shelf plant provide
redundant ringing power. Two- and three-shelf plants offer additional
ringing capacity with up to two ringing generators in each shelf.
Intershelf signal cable adaptor, comcode 847922135, is to be installed at
J7 on each supplementary shelf that has ringers present. This cable is to
be used in conjunction with the two- or three-shelf cable assemblies.
The output ringing power on each shelf is provided on connector J14,
and is electrically isolated from the output ringing power of the other
shelves and from frame ground. Either one of the outputs at J14 may be
connected to frame ground to reference the ringing voltage to frame
ground.
Caution
Do not parallel the output ringing power of a multi-shelf plant
together. Ringer damage may result.
