Recommended Analog Line Settings
Recommended Analog Line Settings
Overview
This chapter describes the recommended configuration settings for the three most
common radio applications of the Model 6300:
1. Extending a 4-wire balanced circuit with in-band control (e.g. tone remote
control) between a fixed radio and its wireline control equipment (e.g. desktop
remote or dispatch console).
2. Extending a 6-wire balanced circuit with out-of-band control using an external
PTT signal between a fixed radio and its wireline control equipment. This is
sometimes also known as Local control.
3. Connecting two radios together as a bridge between two radio bands or two
geographic coverage areas. In this scenario the radios may be either fixed types
(using balanced wireline) or mobile radios (using unbalanced wireline). This
scenario uses an external PTT signal in both directions. This is sometimes also
known as 4-wire E&M with the “Ear” and “Mouth” control signals being
separate from the audio pairs.
The following configuration descriptions focus only on audio and PTT. These various
scenarios may be used with or without simultaneous serial data or general purpose I/O.
