Strata CT I&M Manual October 2000
Configuration C – Three Music Sources
This configuration enables the MOH source to be connected to the RCA jack of the Strata CT
processor PCB (as in Configuration A). The digital or electronic telephone BGM source is
connected to a RSTU or PSTU PCB (as in Configuration B), and a separate BGM source is
sent to the external page speakers via the PIOU PCB (
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.)
