EIA Tone Control

Tone control, also known as an EIA Tone control, is a signaling system used to operate a two-way radio by some form of remote control. Catalyst offers Tone remote control capabilities in each of its dispatch console systems to initiate the Push-to-Talk function and to change channels on the base station or control station. Most radio manufacturers offer a tone control interface for their control stations, allowing tone control to be used for a variety of trunking and conventional over-the-air protocols including SmartNet, MotoTrbo, P25, etc. The use of tone control allows greater flexibility in choosing the base station or control station but has a limited feature set when compared to the Advanced Interfaces that Catalyst provides with specific radio equipment. Contact Catalyst to discuss your specific needs and the trade-offs of using Tone Control versus an intelligent interface.

The simplest tone remote system uses a two-wire audio circuit to operate a simplex base station. If simultaneous transmit and receive is required, a four-wire or full duplex audio path to the base station is required. Catalyst supports both 2 wire and 4 wire tone remote control and MDC 1200 signaling may be optionally added.
