Moh Source As Bgm Installation; Music Source Configuration A - Toshiba Strata DK 280 Installation Manual

6.2.2 BCM 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:
n Configuration A-one music source: This
configuration allows BGM and MOH to share the
same music source. (See Figure 6-3.) With this
configuration, the MOH/BGM music source is
connected to the RCA Jack on the RCTU PCB.
The music source is sent to CO lines/stations on
hold, to electronic/digital telephone speakers, and
to the external page system via either the PIOU,
PIOUS, or PEPU optional PCB.
Note:
Telephone users can turn on BGM at their
station by pressing the
Tel Set Music
(BCM)
button; or by pressing the
Intercom
(INT) button and dialing # 4 8 1. (# 4 8 0
turns BGM OFF).
n Configuration B-two music sources: This
configuration allows the MOH source to be
connected to the RCA Jack of the RCTU PCB (as
in Configuration A) and a separate BGM source to
be connected to a PEKU (Circuit 3), PESU (Circuit
8), RSTU, RSTU2, RDSU, or PSTU (Circuit 2)
PCB (see Figures 6-4 and 6-5). With this
configuration, the MOH source is sent only to CO
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, or PEPU.

Music Source Configuration A
W Configuration C-three music sources: This
configuration allows the MOH source to be
connected to the RCA Jack of the RCTU (as in
Configuration A). The digital or electronic
telephone BGM source is connected to a PEKU,
PESU, RSTU, RSTU2, RDSU or PSTU PCB (as in
Configuration B), and a separate BGM source is
sent to the external page speakers via the PIOU
PCB (see Figure 6-6). When a separate BGM
source is connected to the PIOU, two customer-
supplied amplifiers are required to drive the
external speakers.
One amplifier drives the speakers for BGM when
page is idle and the other amplifier drives the
speakers during page. The PIOU switches BGM
or page to the external speakers via zone relays.
(The PIOUS and PEPU do not provide zone
relays; therefore Configuration C is not possible
with these PCBs.)
6.2.3 MOH Source as BGM Installation
Install the MOH/BGM option in accordance with the
following steps: (Refer to Figure 6-2.)
1. Ensure that the MOH option is installed in
accordance with Subsection 6.2.1, paragraph 2.
2. The output of the RCTU page/BGM control is
applied through the backplane to the output select
switch (SW4) on the PIOU or PEPU.
Note:
The PIOUS provides non-amplified BGM/page
output only (SPT and SPR). See Figure 6-8. '
