F: 11/09/98 DESCRIPTIONsec_3Print Date: 11/10/98 Copyright © 1998 Glenayre Page: 3-13 DESCRIPTION3.1 IntroductionThe Gold Line GL-T8500 and GL-T8600 paging site is generally just one of several sitesin the larger paging network. Equipment and options that comprise a particular site mayvary depending on paging system requirements. Paging site operating characteristics aredetermined by hardware options and controlling software features.Note the distinction between the paging site and the paging transmitter. A GL-T8500 orGL-T8600 paging site consists of a Gold Line paging transmitter, a receiver (non-wirelineapplications), and a transmitter controller. A paging transmitter consists of an exciter, apower amplifier, and a power supply. The receiver and transmitter controller providesupport functions for the paging transmitter which allows it to function as a part of a largerpaging network.The purpose of a paging transmitter is to modulate a specific RF carrier channel withpaging information and amplify it for broadcast. The paging transmitter cannot function ina paging network without the other site equipment. The purpose of a paging site is tobroadcast paging information on a specific channel (frequency) at a specific time. Pagingsite equipment is racked together for practical and functional reasons. The paging sitebroadcasts paging information in response to commands from the paging terminal. All ofthe paging site equipment is usually part of a larger paging network, which is typicallycomprised of several paging sites.3.2 Physical DescriptionRefer to Figure 3-1 and Figure 3-2, for equipment names, identifying features, andequipment racking order. Refer to Table 3-1, for equipment part numbers, and brief descrip-tions. Refer to Figure 3-3 and Figure 3-4, for connector names and locations. Refer to theindividual equipment user manuals for more information.Refer to Figure 3-5, Figure 3-6, Figure 3-7, and Figure 3-8. These provide similar infor-mation as those listed above but feature the C2000 transmitter controller.

A controller may or may not bemounted to the rack with slide rails. By loosening the two thumbscrews on the front of theTXC, the controller slides forward from the rack. By loosening the four top cover thumb-screws, the top can be removed for access to the subassemblies, jumpers, indicators, andadjustments contained in the unit. On the back of the transmitter controller are a variety ofconnectors which are not all used for any one particular application. When using a QT1000controller, do not rely on identifiers which are molded in the back of the TXC; use the appli-cable figures provided in this manual.3.2.5 Link Receiver3.2.5.1 RL-903The 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 adjustmentscontained in the unit. All interconnections to other site equipment are made to connectorson 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 anycompatible laptop or desktop computer running a VT-100 emulation program. The VDThas a brightness and contrast control to accommodate various lighting conditions andprobably has its own power conversion and supply system.3.2.7 Rack CabinetAn air plenum covers the back of the power amplifier when the transmitter is installed in a72-inch rack cabinet; this provides improved cooling. Connectors are accessible with theair plenum removed.3.3 Simplified Functional Description3.3.1 Paging SiteRefer 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 thepaging site through telephone land lines or a link receiver. Incoming information is decodedby the transmitter controller and sent to the exciter / PA control unit, which uses a micro-processor to translate received information into useful paging functions. The exciter / PAcontrol unit generates modulated RF and control signals which are sent to the power ampli-fier. The PA amplifies and broadcasts the modulated RF .

The Gold Line GL-T8500 and GL-T8600 transmittersoperate in a larger paging network. This figure shows how the paging transmitter fits intothe overall paging network.The following paragraphs provide a block diagram-level functional description of a typicalGold Line GL-T8500 and GL-T8600 paging sites.6.2 Simplified Functional Descriptions6.2.1 Paging SiteRefer to Figure 6-4. This figure shows basic signal flows between the various paging siteequipment pieces.6.2.2 Paging TransmitterThe Gold Line paging transmitter converts audio from the receiver or wireline, intomodulated and amplified RF. This function is performed in response to commands from thetransmitter controller via the exciter/PA control unit. The transmitter monitors its functionsand reports its status to the VDT via the exciter/PA control unit. The paging signal isnormally supplied via the transmitter controller, which permits the transmitter to becontrolled and monitored from a remote location. Local control and monitoring isperformed through a VT-100 video display terminal (VDT).NoteIf 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 tooperate properly.6.2.3 Exciter / PA Control UnitThe exciter / PA control unit combines functions of an RF exciter and a PA controller. Theexciter generates modulation using digital signal processing (DSP) to achieve accurate,stable modulation that does not vary with time or temperature. The PA control sectionmonitors transmitter status signals in the form of fault logic and voltage samples. Themicroprocessor in the exciter reports PA status to the controller, VDT, and the exciter frontpanel. If a malfunction occurs, the transmitter enters a reduced operating conditiondepending on the level of the fault. PA control and status monitoring is performed by themicroprocessor, which consolidates control logic from the controller or the locally operatedVDT. Both the exciter and controller receive continuous status reports from the micropro-cessor. The exciter is the control and status-monitoring interface between the transmitterand the user.

F: 11/09/98Page: 6-2 Copyright © 1998 Glenayre Print Date: 11/09/986.2.4 Power AmplifierThe Gold Line PA performs amplification of the RF signal generated by the exciter. Anindicator visible on the front panel lights when the PA is receiving operating power. The PAamplifies a nominal 0.25-watt signal to 250 or 500 watts for application to the antennasystem. Monitoring circuitry is on the metering board in the PA chassis. PA functionsinclude those listed below.• overheat sensing• over-current protection• general fault detection• output level monitoring• input level monitoring6.2.5 Power SupplyThe standard Gold Line power supply takes ac input, converts it, rectifies and filters it, andsupplies dc output to all racked equipment. Each dc circuit is individually fused on the frontof the supply. A circuit breaker on the front of the supply doubles as a transmitter poweron/off switch.6.2.6 Link ReceiverThe link receiver monitors specific RF channels for data, command, and control informa-tion and forwards it to the paging site equipment. The receiver is used in place of atelephone wireline to link the paging site equipment to the paging network.6.2.7 Video Display TerminalThe VDT, though not part of the transmitter, is required for setup, local control, and localmonitoring of the transmitter. The VDT can be any laptop or desktop terminal with a VT-100 type program. The VDT interfaces the transmitter through the connector on the frontof the exciter. The Gold Line transmitter VDT software is menu driven.6.3 Site Signal Flows6.3.1 Site RF Signal FlowThe on-frequency carrier is created by the VCO circuitry in the exciter / PA control unit. Itis then modulated with paging information, amplified, and sent to the PA via connector J3on the back of the exciter / PA control unit. Through coaxial cable, the carrier goes to theback of the PA where it is further amplified to a preset level. The amplified carrier is cabledfrom the PA output to the input of the isolator where it is cleaned up and sent to the antennasystem. Note that some installations have a ten MHz reference signal cabled from thecontroller to connector J8 on the back of the exciter / PA control unit.

F: 11/09/98 THEORY OF OPERATIONsec_6Print Date: 11/09/98 Copyright © 1998 Glenayre Page: 6-36.3.2 Site Audio Signal FlowThe audio signal arrives at the site either through a link receiver or by wireline. The signalcan be either analog or digital and is first routed through the transmitter controller. Thecontroller checks for and responds to appropriate embedded commands. Paging informa-tion is supplied to the exciter. The exciter modulates this signal using digital signalprocessing, then up-converts this modulated signal to final RF. This modulated RF from theexciter is supplied to the PA, which amplifies the signal to the RF output level. This modu-lated, amplified RF from the PA is supplied to an antenna for transmission. An audio-monitoring speaker is available on the RL-903 receiver.6.3.3 Site Control Signal FlowGold Line transmitter paging site control is done two ways: remotely (normal operation),and locally. In either case, the paging site broadcasts when the transmitter controllercommands 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 controlunit, which controls the power amplifier. The exciter / PA control unit also controls thepower 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 hasoverall control of the paging site. The TXC is part of the larger QT-1000 paging controlsystem even though it is racked with paging site equipment. Controller functions includethose 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 transmittercontroller from the external paging control system.Control commands originating from a remote site are supplied to the exciter through thecontrolling device. Control and setup commands may be applied to the exciter locallythrough the VDT. A microprocessor within the exciter interprets each command andresponds by performing the appropriate function.6.3.4 Status Signal FlowThe exciter monitors extensive transmitter status signal in the form of fault logic andvoltage samples. The microprocessor within the exciter reports transmitter status to thecontrolling device, VDT, and the exciter front panel. If a transmitter malfunction occurs, areduced operating condition is entered depending on the level of the fault.6.4 Site SignalsRefer to Figure 6-4 and Figure 6-5.
