Abstract

A radio communication system of base stations, and a telephone system, are linked and controlled by a control center. A housing having a plurality of control modules electrically and mechanically engaged therein, each control module having a front panel with a patch switch and a plurality of indicators thereon, the control modules each adapted to be connected to a transmitter/receiver base station for receiving all communications to and from the base station on an associated communications channel and controlling the operation of the base station, a plurality of buses mounted in the housing and a patch board on each of said modules for electrically connecting any of said modules to said buses upon operation of the patch switch on said module, a phone patch module mounted in the housing and adapted to be coupled to a pair of telephone lines and including a switch for patching any communications channel to the telephone lines upon operation of the switches in the control module for the communications channel and in the phone patch, an operator module mounted in the housing and including a monitor speaker, microphone, and push-to-talk switch and associated circuitry connecting the aforesaid to audio and push-to-talk buses in the housing, and a patch tone encoder module mounted in the housing and supplying a plurality of tones on a tone encoder bus, said tones being utilized by predetermined ones of said control modules to control the base station.

Claims

1. A control center for a radio communications system with interchannel patching capabilities comprising:

a. a housing adapted to have a plurality of control modules electrically and mechanically engaged therein;

b. a plurality of electrically conductive buses mounted in said housing;

c. a plurality of dedicated control modules having a front panel and mounted in said housing, each of said modules being adapted to be electrically connected to a transmitter/receiver base station for controlling all communications to and from its respective base station on an associated communications channel and for controlling the operation of said base station, each of said modules further having a plurality of terminals thereon one each of which is electrically connected to each of said buses;

d. a switch mounted on the front panel of each of said control modules; and

e. a plurality of patch boards one each mounted on each of said plurality of control modules each of said patch boards including associated circuitry electrically connected to the plurality of terminals, to various communications output terminals on the mounted control module and to said switch on the front panel, said switch being connected to provide electrical contact between predetermined ones of the various communications output terminals and predetermined ones of the plurality of terminals for providing selected patching between said normally dedicated communications chanels.

2. A control center as claimed in claim 1 wherein the housing contains a plurality of plugs for receiving modules in electrical and mechanical engagement therein and each module includes a plug for receiving a patch board in electrical and mechanical engagement therein.

3. A control center as claimed in claim 1 including in addition a phone patch module mounted in the housing, said phone patch module including a switch and associated circuitry electrically connected to the buses in the housing and adapted to be coupled to a pair of telephone lines for coupling the telephone lines to predetermined ones of said buses upon operation of said switch.

4. A control center as claimed in claim 1 wherein the buses include an audio and a push-to-talk bus, the center further including an operator module mounted in said housing and including a monitor speaker, microphone, a push-to-talk switch and associated cicuitry, said associated circitry connecting said speaker, microphone and switch to said audio and push-to-talk buses in said housing.

5. A control center as claimed n claim 4 wherein each control module includes compressor amplifier means connected to couple audio between the control module and the audio bus.

6. A control center as claimed in claim 1 wherein the buses include a tone mute bus and a tone encoder bus and the center includes in addition a patch tone encoder module mounted in the housing, said tone encoder module including tone generating means coupled to said tone encoder bus for supplying a plurality of tones in sequence and further including tone mute generating means coupled to said tone mute bus for supplying a signal to mute at least one of the plurality of tones is selected ones of said plurality of control modules.

7. A control center as claimed in claim 1 wherein each control module includes an indicator mounted on the front panel and connected to the switch for indicating when the switch is operated and a patch is in process.
