Peripheral Installation

BGM Options

The BGM options allow music to play over optional external speakers (external page system)
and/or digital and electronic telephone speakers. BGM can be configured in three ways:
Configuration A – One Music Source
This configuration enables BGM and MOH to share the same music source
With this configuration, the MOH/BGM music source is connected to the RCA jack on the
Strata CT processor PCB. The music source is sent to Exchange lines/stations on hold, to
electronic/digital telephone speakers, and to the external page system via the PIOU, PIOUS,
or PEPU optional PCBs. Station Port 000 must dial #491 to send MOH over BGM and
#490 to disable the option.
Source (SHARED)
600Ω, 0.15 - 0.77 Volt RMS

Configuration B – Alternate Background Music Source
This configuration enables the MOH source to be connected to the MOH RCA jack of the
Strata CT Processor, (as in Configuration A) and a separate BGM source to be connected to a
RSTU or PSTU (circuit 2) PCB
source is sent only to Exchange lines/stations on hold, while the BGM source is sent directly
to electronic/digital telephone speakers and to the external page system via the PIOU,
PIOUS, PEPU or BGM 600 ohm RCA jack.

MOH/BGM Music Source Configuration A
Telephone users can turn on BGM at their station by pressing the Tel Set Music
(BGM) button; or by pressing [PDN] + #481 (#480 turns BGM Off).
The BGM source port connected to the system must have the same EN60950
classification as the Strata CT. This port must therefore be of a SELV (Safe Extra
Low Voltage) classification.
