ASTRO 25 Circuit-Based Analog-Only Simulcast Voting Subsystem Equipment Cabling

This section provides a high-level subsystem diagram and equipment cabling tables from the MLC 8000 device to other system devices. A port description table lists the system devices and refers to the device documentation for more information.

ASTRO 25 Circuit-Based Analog-Only Simulcast Voting Subsystem Diagram
ImportantHigh-level diagrams are provided as examples only and are not to be used for system planning purposes. “GPS” in the diagram refers to a Simulcast Site Reference device. The GPS should be connected to the MLC 8000 Subsite Link Converter only if it is connected to an Rx/Tx or Tx only BR.
NoteThis table provides part numbers for cables that are orderable from Motorola. Create the remaining cables using the provided pinout tables. See MLC 8000 Radio Ports Cabling.
