RF-Baton! Transmitter Controller Installation and Operation System Description
June 1999 6880497G01-B 2-11
The Baton Control Module
The BCM controls all functions of the RF-B! transmitter controller. The BCM is primarily
responsible for receiving, processing, scheduling, and sending outbound messages to the
transmitter. While handling the outbound messages, the BCM also maintains GPS tracking,
monitors simulcast capability, monitors transmitter status, and provides a user interface.
Outbound Message Control and Processing
The BCM is the primary controller between the RF-C! controller and the paging transmitter.
The BCM accepts messaging data inputs from the RF-C! controller through the ethernet
auxiliary unit interface (AUI) input/output (I/O) connector on the backplane.
The BCM decodes and converts the messaging data into transmitter-compatible protocols.
The host processor unwraps the message contents from the communications protocol and
processes them. The BCM provides secondary voice processing, calculates launch time and
queues the message for transmission. Once a message launch time has arrived, the processed
message data and appropriate control data are supplied to the transmitter through the
plug-n-play (PnP) interface.
The outbound message dataflow processing occurs in four steps (see Figure 2-5).

• The Outbound Paging Protocol Manager (OPPM) receives the messaging data from the
RF-C! controller over the ethernet and converts the data into compatible protocols.
