COMPLEX REPEATER OPERATION
The MT-4R and MT-4D Repeater modules may be confi gured to operate in complex repeater
confi gurations of up to four sets of transceivers using the CI-RC-4M multiple link controller.
The receiver and transmitter modules connect to the CI-RC-4M repeater controller through RJ45 cables
connected to the front panel of the transmitter and receiver modules. The CI-RC-4M repeater controller
is a 1RU height controller that is installed separately from the radio subrack as shown in Figure 3-2.
Figure 3-2: P25 Repeater System shown with four pairs of transceivers
The CI-RC-4M repeater controller is software programmable to allow fl exible programming options for
the radio system. The CI-RC-4M controller provides the following features:
- interconnection of up to four receiver and four transmitter modules in any confi guration (repeater,
repeater with links, cross-band systems, etc.).
- multiple CTCSS tones and NAC codes may be selected to operate each connection between
receivers and transmitters (up to seven CTCSS/NAC for each link).
- DTMF control of receiver to transmitter links.
- setting of receiver priorities.
- transmitter channel switching based on received CTCSS or NAC.
- auxiliary E&M connections.
- four independent general purpose outputs that can be controlled by NAC, CTCSS or DTMF (open
collector 750 mA / 30 Vdc max).
