F: 11/09/98 3.1 GL-T8500-CN/GL-T8600-CN System Manual DESCRIPTION DESCRIPTION Introduction sec_3 The Gold Line GL-T8500 and GL-T8600 paging site is generally just one of several sites in the larger paging network. Equipment and options that comprise a particular site may vary depending on paging system requirements. Paging site operating characteristics are determined by hardware options and controlling software features. Note the distinction between the paging site and the paging transmitter. A GL-T8500 or GL-T8600 paging site consists of a Gold Line paging transmitter, a receiver (non-wireline applications), and a transmitter controller. A paging transmitter consists of an exciter, a power amplifier, and a power supply. The receiver and transmitter controller provide support functions for the paging transmitter which allows it to function as a part of a larger paging network. The purpose of a paging transmitter is to modulate a specific RF carrier channel with paging information and amplify it for broadcast. The paging transmitter cannot function in a paging network without the other site equipment. The purpose of a paging site is to broadcast paging information on a specific channel (frequency) at a specific time. Paging site equipment is racked together for practical and functional reasons. The paging site broadcasts paging information in response to commands from the paging terminal. All of the paging site equipment is usually part of a larger paging network, which is typically comprised of several paging sites. 3.2 Physical Description Refer to Figure 3-1 and Figure 3-2, for equipment names, identifying features, and equipment racking order.

It is racked where shown and is held in place with four machine screws. The top cover is removable for access to subassemblies, jumpers, and adjustments contained in the unit. All but one of its connectors are on the back of the unit. The front of this unit has a connector which allows the VDT to be connected to it. 3.2.2 Power Amplifier (PA) The Gold Line PA is normally installed above the power supply and is held in place with several machine screws. By removing the front cover, internal components and subassemblies can be accessed without removing the PA from the rack. All PA I/O connections are made from the back. Each power amplifier is equipped with an RF circulator mounted on the PA heatsink. 3.2.3 Power Supply The Gold Line power supply is supported by a shelf that is mounted to the bottom of the rack and is held in place by several machine screws along the bottom front. The perf panel on the supply front is for cooling ventilation; do not obstruct it. Some components can be accessed by removing the perf panel; to access others, the supply must be removed from the rack. All interconnections are made at the back where the connectors are accessible. A connector-ended cable inside the supply allows quick disconnection from the equipment rack wiring harness.

F: 11/09/98 3.2.4 GL-T8500-CN/GL-T8600-CN System Manual DESCRIPTION Transmitter Controller sec_3 The transmitter controller is normally racked at the top. A controller may or may not be mounted to the rack with slide rails. By loosening the two thumbscrews on the front of the TXC, the controller slides forward from the rack. By loosening the four top cover thumbscrews, the top can be removed for access to the subassemblies, jumpers, indicators, and adjustments contained in the unit. On the back of the transmitter controller are a variety of connectors which are not all used for any one particular application. When using a QT1000 controller, do not rely on identifiers which are molded in the back of the TXC; use the applicable figures provided in this manual. 3.2.5 Link Receiver 3.2.5.1 RL-903 The receiver is racked below the transmitter controller. By loosening the top cover screws, the top can be removed for access to the subassemblies, jumpers, and adjustments contained in the unit. All interconnections to other site equipment are made to connectors on the back of the receiver. Refer to the receiver user manual for more information. 3.2.6 Video Display Terminal (VDT) The VDT is required for setup, local control, and monitoring of the Gold Line transmitter. It is also required for local interrogation of the transmitter controller. The VDT can be any compatible laptop or desktop computer running a VT-100 emulation program. The VDT has a brightness and contrast control to accommodate various lighting conditions and probably has its own power conversion and supply system. 3.2.7 Rack Cabinet An air plenum covers the back of the power amplifier when the transmitter is installed in a 72-inch rack cabinet; this provides improved cooling. Connectors are accessible with the air plenum removed. 3.3 Simplified Functional Description 3.3.1 Paging Site Refer to Figure 3-9, for a block-diagram representation of the paging site equipment. The paging site receives paging and command information from equipment outside the paging site through telephone land lines or a link receiver. Incoming information is decoded by the transmitter controller and sent to the exciter / PA control unit, which uses a microprocessor to translate received information into useful paging functions. The exciter / PA control unit generates modulated RF and control signals which are sent to the power amplifier. The PA amplifies and broadcasts the modulated RF . Print Date: 11/10/98 Copyright © 1998 Glenayre Page: 3-3 GL-T8500-CN/GL-T8600-CN System Manual DESCRIPTION Glenayre Document Number: 9110.00163 Rev. F: 11/09/98 The purpose of the exciter/PA control unit is twofold. The exciter section generates a modulated RF carrier which is applied to the input of the PA. The PA control section controls and monitors the PA using a microprocessor based system. 3.3.2 Paging Site Control The Gold Line paging transmitter has divided control functions. Since the power amplifier has no internal control circuitry, the exciter / PA control unit sends commands to the PA and receives status information from the PA. 3.3.3 Link Receiver The link receiver connects the paging site equipment to the off-site paging equipment when telephone land lines are not used. It receives paging data and commands and forwards that information to the transmitter controller. 3.3.4 Video Display Terminal The VDT interfaces the transmitter through the connector on the front of the exciter. Refer to the VT-100 VDT user manual for screen display details. 3.3.5 Interface I/O Board The interface board is mounted to the rear of the exciter / PA control unit with four machine screws. The terminal board and D-sub connector on the interface I/O board provide identical electrical interface through different physical configurations. Refer to the exciter / PA control unit user manual for more information.

F: 11/09/98 6.1 GL-T8500-CN/GL-T8600-CN System Manual THEORY OF OPERATION THEORY OF OPERATION Introduction sec_6 Refer to Figure 6-1 and Figure 6-3. The Gold Line GL-T8500 and GL-T8600 transmitters operate in a larger paging network. This figure shows how the paging transmitter fits into the overall paging network. The following paragraphs provide a block diagram-level functional description of a typical Gold Line GL-T8500 and GL-T8600 paging sites. 6.2 Simplified Functional Descriptions 6.2.1 Paging Site Refer to Figure 6-4. This figure shows basic signal flows between the various paging site equipment pieces. 6.2.2 Paging Transmitter The Gold Line paging transmitter converts audio from the receiver or wireline, into modulated and amplified RF. This function is performed in response to commands from the transmitter controller via the exciter/PA control unit. The transmitter monitors its functions and reports its status to the VDT via the exciter/PA control unit. The paging signal is normally supplied via the transmitter controller, which permits the transmitter to be controlled and monitored from a remote location. Local control and monitoring is performed through a VT-100 video display terminal (VDT). Note If this equipment is to transmit 4-level or higher FSK data, the data lines (1-4) must not be separated by more than 1.8 microseconds in order to operate properly. 6.2.3 Exciter / PA Control Unit The exciter / PA control unit combines functions of an RF exciter and a PA controller. The exciter generates modulation using digital signal processing (DSP) to achieve accurate, stable modulation that does not vary with time or temperature. The PA control section monitors transmitter status signals in the form of fault logic and voltage samples. The microprocessor in the exciter reports PA status to the controller, VDT, and the exciter front panel. If a malfunction occurs, the transmitter enters a reduced operating condition depending on the level of the fault. PA control and status monitoring is performed by the microprocessor, which consolidates control logic from the controller or the locally operated VDT. Both the exciter and controller receive continuous status reports from the microprocessor. The exciter is the control and status-monitoring interface between the transmitter and the user.

F: 11/09/98 Power Amplifier The Gold Line PA performs amplification of the RF signal generated by the exciter. An indicator visible on the front panel lights when the PA is receiving operating power. The PA amplifies a nominal 0.25-watt signal to 250 or 500 watts for application to the antenna system. Monitoring circuitry is on the metering board in the PA chassis. PA functions include those listed below. • overheat sensing • over-current protection • general fault detection • output level monitoring • input level monitoring 6.2.5 Power Supply The standard Gold Line power supply takes ac input, converts it, rectifies and filters it, and supplies dc output to all racked equipment. Each dc circuit is individually fused on the front of the supply. A circuit breaker on the front of the supply doubles as a transmitter power on/off switch. 6.2.6 Link Receiver The link receiver monitors specific RF channels for data, command, and control information and forwards it to the paging site equipment. The receiver is used in place of a telephone wireline to link the paging site equipment to the paging network. 6.2.7 Video Display Terminal The VDT, though not part of the transmitter, is required for setup, local control, and local monitoring of the transmitter. The VDT can be any laptop or desktop terminal with a VT100 type program. The VDT interfaces the transmitter through the connector on the front of the exciter. The Gold Line transmitter VDT software is menu driven. 6.3 Site Signal Flows 6.3.1 Site RF Signal Flow The on-frequency carrier is created by the VCO circuitry in the exciter / PA control unit. It is then modulated with paging information, amplified, and sent to the PA via connector J3 on the back of the exciter / PA control unit. Through coaxial cable, the carrier goes to the back of the PA where it is further amplified to a preset level. The amplified carrier is cabled from the PA output to the input of the isolator where it is cleaned up and sent to the antenna system. Note that some installations have a ten MHz reference signal cabled from the controller to connector J8 on the back of the exciter / PA control unit.

F: 11/09/98 6.3.2 GL-T8500-CN/GL-T8600-CN System Manual THEORY OF OPERATION Site Audio Signal Flow sec_6 The audio signal arrives at the site either through a link receiver or by wireline. The signal can be either analog or digital and is first routed through the transmitter controller. The controller checks for and responds to appropriate embedded commands. Paging information is supplied to the exciter. The exciter modulates this signal using digital signal processing, then up-converts this modulated signal to final RF. This modulated RF from the exciter is supplied to the PA, which amplifies the signal to the RF output level. This modulated, amplified RF from the PA is supplied to an antenna for transmission. An audiomonitoring speaker is available on the RL-903 receiver. 6.3.3 Site Control Signal Flow Gold Line transmitter paging site control is done two ways: remotely (normal operation), and locally. In either case, the paging site broadcasts when the transmitter controller commands the transmitter, via the Gold Line exciter / PA control unit, to key and transmit. Control functions are shared by the transmitter controller and the G/L exciter / PA control unit, which controls the power amplifier. The exciter / PA control unit also controls the power amplifier, locally, by responding to commands from the video display terminal (VDT). Control signals enter and exit the paging site via the transmitter controller, which has overall control of the paging site. The TXC is part of the larger QT-1000 paging control system even though it is racked with paging site equipment. Controller functions include those listed below. • transmitter alarm gathering • transmitter alarm dispatching • simulcast parameter implementation • remote transmitter operation interface. Remote control of the paging site is done through commands being sent to the transmitter controller from the external paging control system. Control commands originating from a remote site are supplied to the exciter through the controlling device. Control and setup commands may be applied to the exciter locally through the VDT. A microprocessor within the exciter interprets each command and responds by performing the appropriate function. 6.3.4 Status Signal Flow The exciter monitors extensive transmitter status signal in the form of fault logic and voltage samples. The microprocessor within the exciter reports transmitter status to the controlling device, VDT, and the exciter front panel. If a transmitter malfunction occurs, a reduced operating condition is entered depending on the level of the fault. 6.4 Site Signals Refer to Figure 6-4 and Figure 6-5.
