Strata CT I&M Manual October 2000
1. Ensure that the MOH option is installed in accordance with
option" on Page 6-4 (see Figure
2. The output of the Strata CT Processor page/BGM control is applied through the
backplane to the output select switch (SW4) on the PIOU or PEPU. Set the SW4 switch
to either SPO or SPI, as required:
N
SPO – Directs external page and non-amplified BGM to the HESB or external
amplifier (pins 13 and 38).
N
SPI – Directs external page and BGM through the on-board 3-watt amplifier to the
external speaker output (pins 25 and 50).
Note
The PIOUS provides non-amplified BGM/page output only (SPT and SPR).
See Figure 6-8.
3. When using an HESB or external amplifier for paging/BGM, adjust volume using the
HESB or amplifier volume control.
4. When using the internal amplifier for paging/BGM, adjust the volume using the volume
control (VR1) on the PIOU/PEPU PCB.
A BGM source can be connected to a station PCB (RSTU/PSTU) to send music to all
electronic/digital telephone speakers and to the external page system via a PIOU, PIOUS, or
PEPU. The BGM source is separate from the MOH source connected to the Strata CT
processor PCB. An isolation transformer is needed to connect a music source to one of the
above standard telephone circuits
See Figures 6-4~6-6 and follow these steps:
1. Access Program 10-2. If the BGM source is connected to a RSTU or PSTU, LED 09
and 10 should be Off.
2. Using Program 19, identify (assign) the BGM slot.
If connecting the BGM source to a RSTU2/RSTU3/PSTU: Connect circuit 2 of the
RSTU/PSTU to a customer-supplied isolation transformer and BGM source.
Note The isolation transformer protects the BGM source from potentially damaging
RSTU2/RSTU3/PSTU voltage. Some music sources which are designed for
telephone system applications may have this protection built-in and do not require
the transformer. (Consult the documentation provided with the music source.)
3. Using the BGM source's volume control, adjust the BGM volume to the desired level
while listening to BGM via a telephone speaker and/or the external page speakers.
When BGM is sent to external speakers via a PIOU or PIOUS or PEPU PCB, use the external
amplifier volume control to balance the BGM and page volume levels.
