Page 15: Tn152 Linked Repeater Networks
TECHNICAL NOTES MT-3/4 Radio Systems TN152 Linked Repeater Networks A linked repeater network is a series of repeaters that are linked together through RF links to create a wide area conventional repeater network that allows for a widely conﬁ gurable system with an expandable area of coverage for mobile and portable radios (subscribers).
Page 16 TECHNICAL NOTES MT-3/4 Radio Systems TN152 Linked Repeater Networks Technical Description Linked repeaters are made up of two transceivers, the repeater (sometimes referred to as the “Drop”), and the Link. The Drop repeaters are on separate frequencies, while the link frequencies are matched (and reversed).
Page 17 TECHNICAL NOTES MT-3/4 Radio Systems TN152 Linked Repeater Networks Linked repeaters can be linked together to form diﬀ erent conﬁ gurations depending on requirements. For larger systems a repeating link may be required as a centralized “hub” for the network as shown in Figure 3. Repeating Links are full duplex and require a duplexer for the antenna connection, and possibly multiple antennas with a power splitter or a multi-directional antenna.
Page 18 TECHNICAL NOTES MT-3/4 Radio Systems TN152 Linked Repeater Networks Some linked repeater conﬁ gurations may also require multiple switched links in order to form a “chain” of repeater links as shown in Figure 4. This requires another set of frequencies and another transceiver pair, but can allow more customizing of the conﬁ...
Page 19: Tn160 Base Station Or Link Conﬁ Guration Settings
The receiver and transmitter modules are used with speciﬁ c control cards to facilitate the external connections of a base station, or to allow the complex connectivity of a linked system. The MT-3 modules are connected to an AC-3E Audio Control Card and the MT-4 modules are connected to a CI-BC-4E Base Controller for base station operation, or a CI-RC-4L Repeater Controller or CI-RC-4M-G2 Multiple Link Controller for a linked system.
Page 20 MT-3 Systems require that two resistors within the receivers be replaced with 47K ohm resistors (1150-4B1002FP). R95 and R96 require replacement in FM receivers. AM receivers require that R35 and R83 are replaced.

Page 29: Tn182 Battery Level Reporting And Remote P25 Test Tone
TECHNICAL NOTES MT-4 Radio Systems TN182 Battery Level Reporting and Remote P25 Test Tone Battery Level Reporting is a method of activating a repeater remotely to have it transmit a signal that reports the battery voltage level over RF. The Remote P25 Test Tone is a remotely activated Standard 1011 Hz P25 test tone transmitted out of a repeater that allows a mobile coverage test to be done with a receiver performing a P25 Bit Error Rate test.
