INTRODUCTION AND OPERATION 1.13.4 POWER SUPPLY The following Sections provide a brief description of the Multi-Net components see Figure 1-3. The 2000 Series Repeater Power Supply is a quad output 800W supply with power factor correction. A battery back-up module, PN 023-2000-830, can be added to the power supply to provide automatic battery revert in the event of AC power failure (see Section 2.5) The Battery Back-Up module charges the batteries when AC is present at the power supply (see Section 2.
PAGE 23
INTRODUCTION AND OPERATION Figure 1-3 MULTI-NET SYSTEM COMPONENTS There are three different types of links that can be selected for the data path between each repeater and the Switch. The MPC is programmed for the type of link used (see Section 2.9). The voice link routes transceiver voice to and from the Switch. The voice must be routed to the Switch when a call involves a dispatcher, telephone interconnect, or another RF channel or Multi-Net system.
PAGE 24
INTRODUCTION AND OPERATION 1.14.4 3000 SERIES SWITCH 1.15 MULTI-NET OPERATION The 3000 Series Switch (or RNT) along with the System Management Module (SMM) or newer Call Processor (CP) control the Multi-Net system. The Call Processor (or SMM) is connected to the Switch and it is an IBM PC or compatible computer running special Multi-Net software. It is used by the system manager to program and control Switch operation.
PAGE 25
INTRODUCTION AND OPERATION If a mobile is trunked to another repeater to receive a call, additional data messages are transmitted continuously by that mobile’s Home repeater, the Status repeater (see Section 1.15.4), and the repeater to which the mobile was trunked. The messages on the Home and Status repeaters tell mobiles just coming into service which repeater to switch to in order to receive the call.
PAGE 26
INTRODUCTION AND OPERATION • Site which access the same site. For example; if systems 1, 3 and 4 access site 128, those systems must be programmed with the same Status channel. Mobiles normally are not assigned to the Status repeater because they would not have Home channel backup. However, if the ID codes of the Status repeater are needed, they can be assigned without any loss in system calling efficiency. A set of repeaters connected to the same high-speed data bus.
PAGE 27
INTRODUCTION AND OPERATION Group ID from 1-225 that it is programmed to decode, it unsquelches and the call is received. The correct Unique ID code does not need to be detected to receive a Standard Call. Standard Calls are limited to other transceivers assigned to the same Home repeater. However, each selectable system of a transceiver can be programmed with a different Home repeater to allow calls to mobiles assigned to other Home repeaters if desired.
PAGE 28
INTRODUCTION AND OPERATION 1.16.6 MOBILE DISABLE Group and Unique ID codes. If an unauthorized ID code is detected, a turn-off code is transmitted to the mobile or mobiles receiving the call. This effectively disables the unauthorized mobile because it cannot talk to any other mobiles. If a transceiver is lost, stolen, interfering with communications or known to be monitoring sensitive transmissions, it can be permanently disabled by the System Manager.
PAGE 29
INTRODUCTION AND OPERATION 1.16.14 VOTER SYSTEM The portable can be programmed so that the emergency message is transmitted either automatically or manually. When automatic operation is programmed, the portable automatically transmits the programmed emergency code on the designated The Multi-Net Voter System may be used to enhance the ability to receive calls from mobiles on the fringes of the coverage area. A voter system utilizes satellite receivers located at outlying sites.

SERVICING SECTION 8 SERVICING 8.1 INTRODUCTION 8.2 SYNTHESIZER SERVICING 8.1.1 PERIODIC CHECKS 8.2.1 INTRODUCTION This repeater should be put on a regular maintenance schedule and an accurate performance record maintained. Important checks are receiver sensitivity and transmitter frequency, modulation, and power output. It is recommended that repeater performance be checked regularly even though periodic checks are not specifically required by the FCC.
PAGE 145
SERVICING 8.2.2 TCXO MODULE Modulus Control Signal Check the signal at TCXO, pin 5. It should be 17.5 MHz for Y201 and Y401 at a level of approximately 3V P-P. If the TCXO is defective, it is not serviceable and must be replaced with a new unit as described in Section 8.1.5. 4. The frequency of the modulus control signal on TEST 1, pin 9 should be equal to the N counter output frequency (either in or out of lock). When the VCO is in lock, this frequency should be 12.5 kHz. 5.
PAGE 146
SERVICING Example: Channel 300 (transmit) Measure the prescaler input frequency at fin, pin 11. Then measure the output frequency at TEST 2, pin 13 and calculate the divide number. If the VCO is not locked on frequency, the divide number should still be correct. The measured frequencies may not be exactly as calculated due to counter accuracy and resolution limitations.

SERVICING Standby Battery Jack Example: 15 pF capacitor This provides a connection point for a +24V DC standby battery. Current is drawn from the battery only when the repeater enable line is on and AC has failed, or no AC is connected. A trickle charger can be jumpered in to charge the battery when AC returns. The charger jumper is removed when a separate battery charger is used (see Figure 8-3). The standby battery connection to the power supply must be ordered installed from the factory.
