Installing The
Ring Generator
You can connect a maximum of two customer-supplied music sources
to the DXP to provide background music and music on hold. The
music sources connect to the jack on the services board. The input
impedance of the music interface is approximately 500 ohms. You can
create a special announcement on hold for outside callers. Remember
that it’s illegal to use a radio station as your music-on-hold.
The ring generator (DXRNG) provides ringing voltage and message
waiting voltage to the industry standard devices. Remember that you
need a ring generator in each cabinet that has an IST board. The ring
generator mounts directly above the power supply in either cabinet,
and it plugs into the backplane. You must have a ring generator in
each cabinet that you use industry standard telephone boards.
