6.0 Configuring The Common Audible Ringing Interface
The services board provides relay actuation dry-contact terminals that you can use for controlling external ringing
equipment. These relays are under programming control. You can program them to provide dry-contact
actuations that track the ringing pattern of any of the programmed flexible ringing assignment ringing patterns.
CAUTION
Do not exceed a 1 amp at 24 volts (0.5 amp at 48 volts) load on these control terminals. If the load
requirements exceed this limit, connect the load through an external slave relay. DO NOT CONNECT
THESE CONTROL TERMINALS DIRECTLY TO THE 120VAC LINE.
