RF SITE EQUIPMENT CONFIGURATION
The following sections provide information about programming the devices that provide the RF
interface (simulcast base radio) to the subscriber radios in your system and the devices that
support the RF interface.
TRAK 9100 SIMULCAST SITE REFERENCE
See “TRAK 9100 Simulcast Site Reference Configuration” on page 2-20 for a full description of
the configuration procedures that cover the general configuration points. This section provides
only the specific settings required for the remote site device.
At the digital simulcast subsystem remote sites, the TRAK 9100 provides 1 pps + 5 Mpps
composite signals to the simulcast base radio. For a total of 30 channels, a TRAK 9100 SSR
with two Digital Distribution Modules (DDM) configured for composite signals is required.
Each composite signal can drive up to six STR 3000 Base Radios. A 50 ohm impedance must
terminate the end of a daisy chain. The 50 ohm load is installed at the STR 3000 Base Radio’s
composite input terminal.
STR 3000 SIMULCAST BASE RADIO
The information provided in this section is for all simulcast base radios installed in the digital
simulcast subsystem at remote and co-located remote sites.
Using the TTY port, connect to the simulcast base radios, and program the IP address required
for this particular station on this channel number at this subsite. IP address information should
be obtained from your Motorola Field Representative. Using Configuration/Service Software
(CSS), program the proper operating frequency for the station and verify proper RF alignment.
Do this for all channels at all subsites. Table 3-1 gives an overview of information that is
configured.
Using the CSS Station Configuration tab, set Simulcast Operation to Enabled.
NOTE
Some fields in the CSS dialog boxes are marked with an asterisk (*). This indicates
a field that can be overwritten from the User Configuration Manager (UCM).
