Base Station System This manual covers the R-8070 based TetraNode Base Station System. Available options, a technical description and guidelines for its installation, operation and maintenance are provided. This manual covers all available frequency band variants and standard configurations. Special configurations and external components such as power back up systems and back-haul networks are not covered by this manual. Guidance notes (for information) are written in italics. Where specifications are given, these are for illustration as they may be subject to change. The definitive figures should be checked on the appropriate product data sheet. The R-8070 transceiver MUST be operated in combination with the supplied antenna combiner system. i.e. The antenna filters, combiners and low noise amplifier are now part of the transceiver. 1.2 Base Station System overview A TetraNode Base Station System is designed to provide the radio frequency carriers for one TETRA base site. As standard it consists of one cabinet containing one to four R-8070 transceivers and all the associated cabling, antenna combining, synchronisation unit(s), optional fall-back site controller, line interfacing and optional power supplies. All Rohill Base Stations are supplied fully assembled and tested. It remains only for antenna connections, power and system (network) connections to be made. Issue 1.2, 06 January 2017 Confidential 16 TetraNode Base Station System 2 System Options 2.1 Number of carriers The standard number of carriers per cabinet is two or four. However cabinets can be sub-equipped for one or three carrier configurations. If more than four carriers per site are required, then multiple cabinets should be co-located. 2.2 Cabinet The standard R-8070 Base Station System (1 to 4 carriers) is supplied in a 1670mm high (32U internal) 19 rack unit. 600x600mm footprint with lockable front and rear doors. Colour light grey (RAL 7047). Front door is solid. Rear door is ventilated (exhaust air) top and lower/middle. Main air inlet is under rack, main air exhaust is lower/middle of rear door. 2.3 Power supply The standard R-8070 Base Station System is supplied from a single +24V

(nominal) DC connection. DC range is 18-36VDC negative earth. 3 and 4 carrier systems are dual-redundant supply as standard. Switching power control and backup (e.g. UPS) must be provided separately and externally. Supply options are available for:

18-36VDC (nominal +24VDC) negative earth AC mains. Input range 100-240VAC 50/60Hz The system is also prepared for 36-58VDC (nominal -48VDC) positive earth please enquire. Configurations can be:

non-redundant, or dual-redundant Figure 1, Single (Non-redundant) power supply, 1-2 carriers Single power input BSS Cabinet IP SWITCH, RMC etc. DC PSU PSU R-8070 R-8070 Optional carrier Optional AC/DC PSUs Issue 1.2, 06 January 2017 Confidential Simplified diagram 17 The R-8070 transceivers are each supplied from their own AC/DC PSU. For true redundant operation two power supply input connections are required. Normally, each input will power half of the equipment in the rack. TetraNode Base Station System BSS Cabinet IP SWITCH, RMC etc. DC R-8070 R-8070 IP SWITCH, RMC etc. Dual power inputs PSU PSU PSU PSU Optional AC/DC PSUs Figure 2, Dual redundant power supply, 2-4 carriers 2.4 Frequency bands R-8070 R-8070 Optional carriers Simplified diagram The transceiver unit(s) used in the system have a fundamental tuning bandwidth of 20MHz. The transmitter and receiver can be independently tuned anywhere in this range subject to permitted configurations [see ETSI TS 100 392-15]. Below 500MHz, this range is further constrained by the antenna filtering solution to a pair of 5MHz sub-bands (normally 10MHz duplex offset). Above 500MHz, with 45MHz duplex split, the full band is covered by one antenna system variant. Standard duplex split is 10MHz when below 500MHZotherwise 45MHz. Other duplex offsets are possible, but may be specials please enquire. Reverse operation is possible on all bands below 500MHz. 2.5 Transmitter output power All powers are quoted as continuous rated RMS values. The maximum output power of the R-8070 transceiver (before antenna combining) is +46dBm rms

(approx 40W). Lower powers (1dB steps down to 33dBm (2W)) are configured in software. Note: the approximate loss of a 2:1 hybrid + duplexer/Tx-filter is 4dB. Issue 1.2, 06 January 2017 Confidential 18 TetraNode Base Station System 2.6 TBS-SYN Timing reference The R-8070 site always contains at least one timing reference. This can be either with or without GPS receiver. Note - Seamless handover is only supported when the system is locked to GPS. A second reference is fitted for dual-redundant operation. The timing reference is normally powered from the R-8070 transceiver(s). Dual power inputs are available for sites with partial redundancy. Specify if required. Timing references without GPS are factory calibrated against GPS. They are designed to run for 10 years within specification. Caution:

The calibration of the crystal reference in the TBS-SYN can be detuned by mechanical shock. References so affected must be reconnected to a GPS signal until auto-calibration has settled and corrected any errors. Attention:

L'talonnage du cristal de rfrence du TBS-SYN peut tre dsaccord par choc mcanique. Les rfrences ainsi touches doivent tre reconnectes un signal GPS jusqu' ce que lauto-talonnage soit termin et les erreurs corriges.

Exposure to solar radiation should be limited. High humidity can be tolerated, but MUST be non-condensing conditions. Air conditioning is only required if the performance envelope of the equipment inside the rack would otherwise be exceeded. However, improved life time and performance will be achieved if temperature is kept below extremes. Temperature performance of the carriers is defined at the air-intake of the transceiver sub-rack. Issue 1.2, 06 January 2017 Confidential 21 TetraNode Base Station System 3 Technical description 3.1 R-8070 transceiver 3.1.1 Transceiver User Interface (MMI) The User Interface or Man-Machine Interface (MMI) is provided by a 4.3 inch full-colour LED-backlit touch-screen LCD display mounted in the front panel see Figure 5.

An alarm is something that is critical to continued operation, e.g. will/has caused failure. If a warning state occurs, the alarm tab-key is highlighted yellow. A warning is something that affects performance but is non-critical e.g. temperature unusually high. In normal operation, the alarm tab-key is black or blue(selected). For a full list of alarms & warnings see section 6.2 If the transceiver is in screen-saver mode, the display will wake-up when an alarm or warning occurs. 3.2 Synchronisation TBS-SYN The TBS-SYN provides a high stability reference clock from a precision oven-

controlled oscillator. Once calibrated, this oscillator will stay within specification for ten years or more. However free-running systems (no GPS antenna) should be periodically checked for accuracy in case of mechanical shock or other detuning. Fitting the GPS receiver antenna is strongly recommended. GPS satellite timing signals provide a master reference to phase lock and auto-calibrate the ovened crystal reference. GPS reception is essential for systems supporting seamless handover. One unit can synchronise up to 16 transceivers. Two units are fitted in dual-

redundant system designs. Connections to transceivers are made with star connected RJ-45 cables. Power and timing-reference cables are <3m to comply with EMC requirements. The TBS-SYN is designed to be powered from one or two R-8070 base station transceivers. The second power cable is only fitted as a special as it is only required by partially redundant systems. E.g. in the case that one TBS must be removed without disabling the other(s). A TBS-SYN contains one GPS receiver with a 3.3V DC power output on the receiver MCX connector for powering a remote active antenna. The antenna and lightning protection must guarantee a DC feed with no short circuit to the active antenna. Management and GPS signal quality information is available to the network via the transceiver control. Issue 1.2, 06 January 2017 Confidential 27 TetraNode Base Station System 3.3 Connections 3.3.1 R-8070 connections 3.3.1.1 IP connections In normal systems standard Ethernet network components can be used. However some basic checks should be made:

First make sure that the Ethernet backbone is a dedicated service with a high degree of reliability, say at least an availability of >99.99%. Virtual private networks over the Internet may be cost effective, but are unreliable, especially considering the packet delay and jitter. Secondly, it is desirable to use a Quality of Service mechanism using DiffServ, also called Differentiated Services Codepoint (DSCP). This allows the operator to carry different classes of traffic over the IP network, the service for connecting TetraNode base stations will use Expedited Forwarding mode. Make sure this is supported. 3.3.1.2 Transmit Antenna connector The female-N-type Tx power connector at the rear of the transceiver has a 50 W unbalanced characteristic impedance. It is connected to the antenna system with a good quality flexible double screened coaxial cable. The transmitter antenna system should always provide at least 80dB transmit to receive isolation. Therefore always ensure good connections and maximise Rx-

Tx cable separations. Isolators are built-into 20MHz bandwidth PAs as standard, thus the R-8070 is suitable for multi-Tx sites without supplementary intermodulation protection. Extra isolators are also present in the hybrid or cavity combiners. There is a red-LED next to the output connector. Do NOT remove the antenna/load if this is lit. Issue 1.2, 06 January 2017 Confidential 28 TetraNode Base Station System Caution:

transmitter cables are often critical lengths and should not be cut or mixed up. This is especially true for cavity combiners. Attention:

Les cbles de l'metteur ont souvent des longueurs critiques, et ne doivent pas tre coups, ni mixs. Cela est particulirement vrai pour les multiplexeurs de cavit. 3.3.1.3 Receiver Antenna connectors The three female snap fit QMA receiver antenna(s) connectors at the rear have a nominal 50 W unbalanced characteristic impedance. All three inputs are equivalent. To provide diversity gain, connect the receivers to physically separated antennas. Ideal diversity separation 7 to 10 lambda (wavelengths). For best performance, diversity antennas should be at the same height (so that they receive comparable average powers) If multiple R-8070s are used on one site, then received signals are normally split with a Receiver Multi-Coupler. The amplifier in the Coupler must have noise figure and OIP3 performance similar to the R-8070 in order to preserve performance. On sites with strong signals from other systems, ensure that the receiver amplifier is far from overload. A band limiting filter (pre-selector) should always be fitted

(usually part of receiver multi-coupler or duplex filter). Transmit-receive isolation should exceed 80dB. Use double-screened coax and maximize physical separations between Rx-Tx (e.g. dress cables on opposite side of the rack). Unused receivers should be disabled (see configuration) to optimize system performance. 3.3.1.4 Synchronization inputs The reference frequency and synchronization data from the TBS-SYN enters the R-8070 via the SYNC input connector. The spare input is for use in dual-

redundant systems. The R-8070 is designed for a (dual) star connection of synchronisation clocks. Issue 1.2, 06 January 2017 Confidential 29 TetraNode Base Station System 3.3.1.5 RS-232 / DE-9 connector An asynchronous RS-232 serial port is available on the DE-9 connector. This connector is intended only for testing and alignment of the R-8070 during manufacturing, and cannot be used during normal operation and maintenance. 3.3.1.6 Protective earth One of the rear panel mounting screws should be connected to the rack protective ground with a short heavy-gauge cable (minimum cable 7/0.85 mm (4 mm2)). To minimise inductance, this cable should NOT be looped/ coiled as it is to provide operator and equipment protection from fast transients and surges. The equipment rack/housing in turn should use a heavier gauge cable/strap to connect to the communications room protective earth. If in doubt, consult an expert on lightning protection. Warning:

The protective earths within the TetraNode Base Station should be adequately bonded to the electrical earth of the 19 rack cabinet and NOT to any lightning protection system for transmitter-towers/antennas. Avertissement:

This section describes the installation after delivery. The cabinets are shipped fully equipped and ready for use. The basic sequence for installation should be:

1. antenna earths and lightning protection 2. equipment room earths (separate from (1)) 3. antennas and cables 4. equipment room power-supplies and lighting 5. cabinet placement 6. cabinet earths 7. antenna connections 8. network connections 9. cabinet power connections 10. configure, test and commission (include updating site documentation) Warning:

Ensure that cables do NOT lie across any sharp metal edges. This applies to ALL cables of all types. Avertissement:

S'assurer que les cbles ne se trouvent PAS sur des bords mtalliques tranchants. Cela s'applique TOUS les cbles de TOUS types. 4.1 Equipment room requirements Equipment must always be operated in a secure manner i.e. with locked doors and/or in locked authorised access only areas. Thus, if possible, choose equipment room locations that are secure, but do not require extra special permissions/training for personnel requiring access (e.g. intrinsic safe areas in oil refineries or hygiene restrictions of drinking-water towers). All standard TetraNode variants are designed for installation in a weather protected (dry) environments, i.e. an equipment room, except for some specials, such as the ultra-lite and transportable cabinets Issue 1.2, 06 January 2017 Confidential 32 TetraNode Base Station System In all cases, humidity may be high, but must be non-condensing. Condensation may be prevented by keeping equipment temperatures higher than circulating air temperature. Consider the likelihood of rapid rises in air temperature that may leave equipment (with high thermal mass) temporarily at a lower temperature. In the equipment room, ensure that temperature remains within the maximum and minimum operating-limits of the equipment in use. This is usually defined with respect to the (ambient) air inlet of the component in question. It may be necessary to consider the effects of closed cabinet operation and (for specials) ancillary equipment that may be mounted in the rack. Requirements for air conditioning (chillers) can usually be avoided due to the wide operating range for TetraNode equipment, thus saving considerably on running costs. NB Low temperature operation will generally lead to longer equipment life. The equipment room should be dry and relatively dust free (clean) and vermin free. For all other environments, the equipment should be fitted in an appropriate environmental housing. 4.1.1 Equipment-room earth The equipment room should have its own low-impedance protective earth system separate from that of the antenna tower. All incoming/outgoing cables should also be protected (earthed) at the entry point to the equipment room. Equipment room earth should ideally be constructed as a halo over the equipment with connections to ground at the corners. This effectively creates a Faraday cage over and around the equipment. Warning:

Do not connect equipment-room earth to the same earth used for the tower lightning protection. Avertissement:

Ne PAS connecter la prise de terre de la salle dquipements la mme prise de terre du paratonnerre de la tour. When sited near railways also consider extra shielding from magnetic fields and anti-vibration mounts for equipment. Issue 1.2, 06 January 2017 Confidential 33 4.2 Installation floor standing cabinets TetraNode Base Station System Standard R-8070 Base Station configurations are supplied in a 37.5U 19 floor standing cabinet (600x600mm footprint) with supporting shelves or slide rails. The system components are held in the rack by M6 (pozidrive) screws. The cabinet is designed for internal-cable access at the rear and normal operation/monitoring from the front. External cables can enter either through the cabinet floor or the lid. The rack is supported on four feet, but also has two wheels at the front for easy installation. When in position, wind the feet down to equalise the support and level the cabinet. Ensure that the rear panel can be lifted off if required and the associated earth strap can be removed/replaced without damage. Ensure that the cabinet will be adequately lit when being worked on. NB. Doors are hinged on the left. Ensure the earth is connected first. 4.2.1 Ventilation and cooling Cool air is required at the front/underside of the R-8070 cabinet. Hot air is exhausted at the rear/top. Ensure that hot air is NOT recirculated into the inlet. Sufficient ventilation to remove typically 190 W per carrier (on full power) and worst case 250 W should be provided. Typically an area of 2 x (15 cm x15 cm) per carrier should be sufficient for the inlets and outlets respectively. Allow extra ventilation for cooling of hybrid combiner, power supplies, fall-back site controller, IP-switch and TEP-rack, as required. Ensure that the installation location is clean to prevent build up of dust in the ventilation grills. Ventilation ducts should be screened with a thin mesh of ~1 cm to keep vermin/debris out and yet not get clogged with dust. Issue 1.2, 06 January 2017 Confidential 34 4.3 Power-supply and Earthing TetraNode Base Station System Warning:

All power installations must additionally comply with all local wiring regulations. Avertissement:

Toutes les installations dalimentation doivent en outre se conformer aux rgulations locales de cblage. Warning:

The cabinet(s) must be supplied via READILY ACCESSIBLE power switch(es). Avertissement:

Les armoires doivent tre quipes dinterrupteur(s) d'alimentation facilement accessible(es). Warning:

If dual power supplies are used for redundancy, ensure warnings are clearly posted on the cabinet and double circuit isolators are provided. Each isolator must be double-pole, with certified breaking capacity and voltage rating suitable for the cabinet version in question. Avertissement:

En cas dutilisation de deux sources d'alimentation dans un but de redondance, prendre soin dafficher clairement les avertissements sur larmoire et de fournir une isolation double circuit. Chaque isolateur doit tre en double-pole, avec une capacit de rupture certifie et une tension nominale convenant la version de larmoire en question. Warning:

The protective earth point within the TETRA Base Station cabinet should be adequately bonded to the electrical earth of the 19 rack cabinet and NOT to any lightning protection system for transmitter-towers/antennas. Issue 1.2, 06 January 2017 Confidential 35 TetraNode Base Station System Avertissement:

Le point de mise la terre de l'armoire de la station de base TETRA doit tre adquatement joint la mise la terre de la grille 19" de l'armoire et NON au systme paratonnerre des pylnes dmission/d'antennes. Warning:

If connecting to floating power supplies take care to minimise touch-currents. Correctly earthed supplies are preferred over floating supplies. Avertissement:

Lors dune connexion une source dalimentation instable, prendre soin de minimiser les fuites de courant. A privilgier les sources fixes dalimentation, correctement mises la terre. 4.3.1 Earthing Firstly - All cabinets must first be permanently cross-bonded (connected) to the protective earth point(s) to protect operators from dangerous surges and possible touch currents from 3rd party equipment. Use only a single star connection point. Max cable length 2m. Use double crimped or soldered and strain-relieved ring terminals, do not use spade terminals. Earth connections must be low impedance (minimum cable cross section MUST exceed that of the (total) supply cable. In any case minimum 7/0.85 mm cable (4 mm2) per two carriers. Once the protective earth connection is made, other work may proceed. If multiple cabinets are installed, independently star-connect them to the safety earths. If third party equipment (e.g. power supplies, line equipment) are used, check that the touch currents (leakage to ground) will not accidentally trip building RCDs

(residual current breakers). 4.3.2 AC Power cables All cables must be installed so as to avoid abrasion (wear) and other forms of damage. Do not run cables over any unprotected metal edges. Issue 1.2, 06 January 2017 Confidential 36 TetraNode Base Station System The AC power cable must use conductors with cross sectional area 1.25mm2 per cabinet. Use only (marked) certified cable types (tested for safety and compliance with ratings). Supplied power cables can be directly connected into isolation switches. Always switch both live and neutral (or in a DC system + and - ). Switches MUST be located in a readily accessible location. Dual power supply installations must be clearly labelled and equipped with dual circuit isolators. Each isolator must be double-pole, with certified current-

breaking capacity and voltage rating suitable for the cabinet version in question. 4.3.3 DC Power cables A low impedance DC power supply should be connected to the transceiver power supply input connector (two pins only). The connector is a Phoenix type and is available from Rohill or your Rohill distributor. Use colour-coded multi-strand cable with a minimum cross-section of 2.0 mm2 per transceiver for the power supply. All cables should be insulated and be strain relieved as a short circuit could cause a fire hazard. If long cables are used (>1.5m), compensate for voltage drop and protect against transients and surges. Maximum cable length 3m. Power cables with 7/0.85 mm (4 mm2) cross section with conductors are suitable for one pair of carriers. A cabinet with 3 or 4 carriers is designed for double cables, 2 positive and 2 negative cables because the single cable alternative would be more than twice as heavy. Supply redundancy is therefore standard for 3 and 4 carrier configurations. 4.3.4 Power supply Ensure the power supply is capable of providing more than the rated power of the cabinet under all conditions, allowing also for turn-on surges. If necessary protect equipment from brown-out (voltage dip), over-voltage and supply failures. Although the power inputs are protected against transients and surges, if connecting to an alternator or generator system (especially a vehicular/generator power supply) care must be taken to provide additional filtering of noise/transients. 4.4 Network Connections IP over Ethernet requires 50 kbps bandwidth per R-8070. In either case, total delay to the TNX should not exceed 20ms. If it does, the system will still work, but PTT delays will be increased. Also ensure that the jitter is kept below 4 ms to minimise buffer sizes. Issue 1.2, 06 January 2017 Confidential 37 The IP address(es) for the transceiver can be entered via the front panel LCD. TetraNode Base Station System 4.5 Antenna system 4.5.1 Lightning protection Warning:

The reader is advised to seek specialist advice on this subject1. Rohill accepts no liability for failure of designs that may be based upon the following advice!

DO NOT WORK ON OR TOUCH ANY SYSTEM WHEN LOCAL ELECTRICAL STORM ACTIVITY IS PRESENT. Avertissement:

Il est recommand au lecteur d'obtenir des conseils spcialiss sur ce sujet1. Rohill n'accepte aucune responsabilit en cas dchec de conception qui peuvent tre fonds sur le conseil suivant !

NE JAMAIS TRAVAILLER OU TOUCHER N'IMPORTE QUEL SYSTME EN CAS DORAGE VOISIN/LOCAL. A correctly designed lightning protection system can protect a radio transmitter from the effects of most direct strikes. Adding effective protection to a system after initial installation can be considerably more difficult, therefore consider lightning protection requirements from the outset of system design. Lightning protection components are not supplied as standard and are the responsibility of the antenna-site engineer. 1 Issue 1.2, 06 January 2017 Confidential 38 4.5.2 Minimization of exposure to non-ionizing radiation TetraNode Base Station System Warning (IC RSS-102, Sec 2.6):

This base station emits radio frequency (RF) energy when transmitting. Make sure to observe all RF energy exposure standards when installing, testing and operating this radio equipment. Proper operation of this base station under normal conditions results in user exposure to RF energy below standard acceptable limits. Do not allow the antenna to touch or come in very close proximity with the eyes, face, or any exposed body parts while the base station is transmitting. The warnings in this document are not intended to include all hazards that may be encountered when using this base station. Avertissement (IC RSS-102, Sec 2.6):

Ce station de base met des frquences radio (RF) lors de la transmission. Assurez-vous de respecter toutes les normes d'exposition l'nergie RF lors de l'installation, les essais, la rparation et l'utilisation de ce matriel radio. Le bon fonctionnement de station de base dans des conditions normales entrane l'exposition de l'utilisateur l'nergie RF en dessous des limites du standard acceptables. Ne pas laisser l'antenne entrer en contact ou proximit des yeux, du visage ou des parties du corps exposes lorsque le station de base transmet. Les avertissements contenus dans ce document ne vise pas inclure tous les dangers qui peuvent survenir lorsque vous utilisez cette station de base. In Europe, in order to comply with Council Recommendation 1999/519/EC on "Limitation of exposure of the general public to electromagnetic fields

(0 Hz to 300 GHz)" the following actions should be performed for every new or re-engineered transmitter site. Figure 9, Non-ionizing radiation warning As a minimum, the commissioning engineer should perform a calculation to show that the general public will not be exposed to electromagnetic fields in excess of the recommended levels. This calculation is to be signed and stored with the commissioning documentation file for the site. Issue 1.2, 06 January 2017 Confidential 39 TetraNode Base Station System As an alternative to calculation, a measurement may be made to demonstrate compliance in which case calibration details of measuring equipment and measurement results should be recorded in the file. Where service/maintenance personnel require access to areas that will exceed the levels stated for exposure of the General Public, non-ionizing radiation warning signs are to be displayed (see Figure 9). Warning (IC RSS-GEN, Sec 8.3):

The BSS has been approved by the Industry Canada to operate with the antenna types listed in the table below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Avertissement (IC RSS-GEN, Sec 8.3):

At power on, the BSS carriers announce themselves to the TNX. The R-8070 identities are captured by the TNX by means of the Plug and Play procedure. The identities are matched against system configuration database and configuration are sent to each unit. New (unknown) carriers will be automatically added to the database and made visible in the NMS. The manual for the NMS describes the exact procedure used to configure an R-8070 carrier and also gives detailed information about the parameters. In summary, the following parameters are sent to a BSS to configure a carrier:

Channel number

(channel# = (frequency_in_MHz - Base_Frequency )/0.025) where Base Frequency = 300, 400 or 800 MHz. Transmitter output power (dBm, 1dB steps) Duplex orientation (Tx high | Tx low), default = Tx high, only variable for frequencies below 500MHz Duplex offset, (7 | 8 | 10 | 18| 45) default= 10MHz below 500MHz, otherwise 45MHz Receiver selection (enable | disable), default= all enabled To minimise received noise and reduce power consumption, unused Rx inputs should be disabled. The basic procedure is as follows:

1. Power-up the BSScabinet. The R-8070s announce to the TNX but the blue 2. Sync display marker is still off. If required, a TETRA site must be created in the NMS. All parameters for the site have a default value, which is sufficient in case of a single site system. For a multi site system the parameters need to be configured to enable handovers. Make sure the site is enabled. 3. Now the R-8070 carriers must be associated with site. Fill in the carrier number and select the channel plan profile. Select the required output power and enable the receivers to be used. 4. The carrier will now become enabled. The blue Sync display marker will illuminate to indicate that the R-8070 is registered and enabled on the TX. After a timeout only the heartbeat will be shown on the display to indicate that the device is in service and ready to operate. Issue 1.2, 06 January 2017 Confidential 41 TetraNode Base Station System 5 Maintenance and replacement 5.1 General This section describes the preventive maintenance actions for the TETRA Base Station System. It also describes the replacement of the components within a BSS. Defective units are replaced as a complete unit and repaired in the factory. 5.2 Maintenance policy There are NO end-user or distributor serviceable parts within the components of a TetraNode Base Station (such as an R-8070 or R-855 TBS-SYN). Spare parts are complete sub-rack components. Spares holding and support requirements should be negotiated through your Rohill representative. The network connection(s) can be used for actions such as remote download of software updates. The transceiver controller can hold multiple software versions and permits synchronised network change-over between software versions. 5.3 Maintenance The TetraNode Base Station System is designed as a maintenance-free installation. No alignment is normally necessary during the lifetime of the equipment. Also no consumables are necessary to keep the system in operation. Preventive maintenance should include the following checks to ensure the system is operating within specification limits. These tests can be performed from the NMS. See the NMS user manual for detailed information how to obtain the information. Check PA temperature (and fan speed); if this is significantly above normal limits, the airflow may be obstructed. Check the RF output power of the R-8070. The measured power should be within 2 dB of the selected RF output power. If the measured power is outside these limits, first check whether the problem is caused by antenna mismatch (fault). If not, the R-8070 should be replaced. To check for antenna system mismatch, check the reflected power. The measured reflected power should be below 30% of the selected RF output power. If the reflected power is higher, verify whether the antenna, coaxial cables, duplexer and combining equipment are working/tuned correctly. Check the Alarm and Failure flags. If there are any reported errors, take action to clear them as described in section Error codes R-8070. Issue 1.2, 06 January 2017 Confidential 42 TetraNode Base Station System 6 Troubleshooting 6.1 General Caution:

Service and /or maintenance of the equipment should only be carried out by qualified service technicians. Attention:

Les services et/ou la maintenance de l'quipement ne doivent tre effectus que par des techniciens de service qualifis. Diagnostics are performed locally or remotely with appropriate software and repair is by component replacement. Fault find should be step by step to prove that each component of the system is operating normally. Faults can often be isolated by swapping suspect units with known good ones, however exercise care not to damage further equipment e.g. due to faulty antenna or power connections. 6.2 R-8070 Alarm messages The R-8070 executes continuous measurements on critical parameters such as output power and level of linearization (which influences the quality of the transmitted signal). Errors are indicated by means of error codes shown on the front panel of the R-8070. Code A1 A2 A3 A4 Description No TNX connection Base station disabled IP data link failure Possible remedy 1.
