Chapter 8 MTR3000 Wireline
8.1 Description
The Wireline Interface Board is described in this section. A general description, identification of
inputs and outputs, a functional block diagram, and functional theory of operation are provided. The
information provided is sufficient to give service personnel a functional understanding of the module,
allowing maintenance and troubleshooting to the module level.
8.1.1 General Description
The MTR3000 Wireline board is used to connect an analog audio source and sink (such as a
console) to the MTR3000 Base Station/Repeater. The Wireline board supports Tone and DC Remote
Control modes that allow for channel selection and PTT signaling from compatible consoles. Local
PTT operation is also supported. The Wireline can be configured for either 2-wire or 4-wire operation
as needed.
Although the Wireline is installed as a card inside the MTR 3000 Base Station/Repeater, its operation
is similar to an External Tone Remote or a DC Remote Adapter. The Wireline board drives the same
GPIO signals that an external controller would drive if it were connected to the J7 DB-25 connector
on the back of the base station/repeater. Despite the similarities with an external controller, almost all
Wireline options are configured through the CPS and Tuner software configuration tools, just as the
other base station/repeater options are.
