MOH Contacts, 
BUSINESSCOM PLUS 
This section provides information on installing an
external device to MOH Contacts.
The B-HBU-A PCB has
an auxiliary relay for MOH that is energized when a
call is placed on Hold.
The energized relay provides
a closure for control of an audio source.

Installing Paging Equipment
External Paging 
ContactsExternal zones have normally open contacts. If a
zone is activated,the contacts close. When a zone
receives BGM,the contacts become continually closed.
The relays for each zone are energized when Paging
amplifiers are in use,including CO audible and BGM
(if programmed).The relay is on the 
 PCB in
the BUSINESSCOM PLUS 
 The relays are on the
B-GCU-A PCB,a daughter board on the tone sender PCB
(B-TSU-A) in the BUSINESSCOM PLUS
