1 TECHNICL NOTES TN CIRCMG Multiple Link Controller MT Radio Systems The CIRCMG Multiple Link Controller provides control capability for up to four receiver / transmitter pairs in an MTE repeater radio system. The CIRCMG controller provides the following features: interconnection (LVS Serial ata routing, CORPTT routing, udio routing) of up to four receiver and four transmitter modules in any confi guration (repeater, repeater with links, crossband systems, etc.). fourway analog audio bridge allowing analog to digital and digital to analog conversions with up to four pairs of radios (with adjustable audio levels). multiple CTCSS tones and NC codes may be selected to operate each connection between receivers and transmitters (up to seven CTCSS/NC for each link). TMF control of receiver to transmitter links. setting of receiver priorities. transmitter channel switching based on received CTCSS or NC. auxiliary E&M connection. acknowledge tones for each transmitter on TMF disable / enable. custom jumperable Repeat isable line for controlling analog bridging (links) and E&M connections. current draw of m to m dependant on system confi guration ( m to m without audio bridging). independent general purpose outputs that can be controlled by NC, CTCSS or TMF (open collector 0 m / 0 Vdc max). The MTE receiver and transmitter modules all plug into the CIRCMG repeater controller via cables that plug into the RJ jacks on the front panel of all the modules. The CIRCMG comes with eight different cable lengths to plug into the eight repeater receiver and repeater transmitter modules. If the system only uses some of the cables, the other cables can be kept for future system expansion or as spare cables. The CIRCMG is rack mountable in RU of rack space.

5 TECHNICL NOTES TN CIRCMG Multiple Link Controller MT Radio Systems nalog udio Bridging Circuit: The CIRCMG controller is equipped with a way analog audio bridge. This audio bridge allows the user to interconnect RF modules using an analog audio interface similar to the CE and BCE products. It allows the user to interconnect up to four RF modules modules as well as an auxiliary audio input and output. On the multilink controller there is an audio adjustment pot for each audio path available. The block diagram on the next page (see Figure ) shows the audio routing and audio pot adjustments. To enable a specifi c audio path, the appropriate audio jumper must be removed. For the specifi c audio jumper required for enabling the appropriate audio path, refer to the jumper table below: JU RX to udio isable JU RXC to udio isable JU RX to B udio isable JU0 RXC to B udio isable JU RX to C udio isable JU RXC to C udio isable JU RX to udio isable JU RXC to udio isable JU RXB to udio isable JU RX to udio isable JU RXB to B udio isable JU RX to B udio isable JU RXB to C udio isable JU RX to C udio isable JU RXB to udio isable JU RX to udio isable JU RX to ux udio O/P isable JU0 RXB to ux udio O/P isable JU RXC to ux udio O/P isable JU RX to ux udio O/P isable To enable CORPTT routing of the signla, the following jumpers must be installed: JU COR to PTT Enable JU COR to PTT C Enable JUB COR B to PTT Enable JUB COR B to PTT C Enable JUC COR C to PTT Enable JUC COR C to PTT C Enable JU COR to PTT Enable JU COR to PTT C Enable JU COR to PTT B Enable JU COR to PTT Enable JUB COR B to PTT B Enable JUB COR B to PTT Enable JUC COR C to PTT B Enable JUC COR C to PTT Enable JU COR to PTT B Enable JU COR to PTT Enable Erie Street Canada VV P Toll Free Canada & U.S..
