Music-On-Hold/Background Music Interfaces

Strata CTX provides up to 15 MOH/BGM music source interfaces via the ACTU or BECU system
processor PCB, one or two BIOU optional interface PCBs, and RSTU standard telephone interface
PCBs. The destination of each music source is determined by system programming. The music sources
can be standard CD music players, telephony MOH machines and/or tape players, etc. The music
sources are connected to standard RCA type jacks on ACTU or BECU and BIOU and via a dealer-
supplied isolation transformer to RSTU (see
MOH is sent to callers placed on hold and BGM is sent to DKT telephone speakers and/or external
page speakers.
The ACTU, BECU and BIOU interfaces provide an input volume level control for each music source.
The volume levels of music sources connected to RSTU circuits rely strictly on the music source
volume controls.
MOH/BGM source output requirements:
Output Impedance: 600 or 8 ohms
Output voltage level: 0.14VRMS (-15dbm) ~ 0.77VRMS (0dbm).
An additional separate BGM source can be connected to the building's external page amplifier to play
music over the paging speakers when the Strata CTX Page is not in use. This interface option requires
the BIOU zone relays or mute control (see External Page with BIOU Interface).
