2. INTRODUCTION

2.1. PURPOSE Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) / Node B and mobile stations (MS) / UE within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system. Such a system contains an optical Master Unit (consisting of up to 13 racks) and several Remote Units (RUs). The number of the RUs depends on the hardware and software configuration. The RUs are connected to the Master Unit with optical links. The optical loss must be less than 10 dB. The Master Unit is the connection to the BTS / Node B. The configuration of a Master Unit depends on the number of the RUs and the frequency range. The optical transmission uses WDM-systems with a wavelength of 1550 nm in the uplink and 1310 nm in the downlink.

2.2. THE ION-M MASTER UNIT The fibre-optic distribution system is designed for GSM, AWS and UMTS services as well as for AMPS/ PCS or iDEN/ PCS or Tetra services. In general, up to three frequency bands can be transmitted. Each sector will be able to serve up to four remote units and to operate services of up to four providers each in three frequency bands. The Master Unit is the link between BTS / Node B and the corresponding ION-M RUs connected to the Master through optical-fibre lines. It is the conversion unit from RF to fibre optic. One Master Unit can support up to 124 RUs in point-to-point connections or 124 RUs in a cascaded system with up to four RUs per link. The Master Unit controls the complete system and also the auto-levelling function. An auto-levelling function for compensating different fibre losses and a comprehensive supervision concept are implemented. Auto-levelling in DL works with optical power measurement, in UL a 10.7 MHz signal is used for measuring the optical loss. Thus a (“cascaded”) backbone structure can be used in the optical network, i.e. up to four RUs can be connected to the Master Unit via only one fibre and optical couplers. In newer revisions of RUs the optical wavelength will be tuned automatically. So there is no need for choosing different optical interfaces with different wavelengths. The new units are fully downwards compatible to the older versions. So it is also possible to combine older and new RUs to the same optical fibre.

3. FUNCTIONAL DESCRIPTION

3.1. GENERAL

E0975B9 figure 3-1 Overview of the ION-M Master Unit, first rack

In a typical configuration, the ION-M Master Unit comprises two signal chains per optical link. In the uplink direction, the optical signals from the RUs (transmitted via optical fibres) are converted into RF signals by the transceiver. Then, they are forwarded via a frequency separation unit denominated as duplexer and the four-way combiner or BTS connect (one for each band) to the connector, which transmits the signals to the BTS / Node B. In the downlink direction, the signals from the BTS / Node B are forwarded to the four-way combiner. After passing through the duplexer, the RF signals are converted into optical signals by the transceiver and finally are transmitted via optical fibres to the RUs. This typical configuration can vary depending on the respective ION-M system.

3.2. COMPONENTS OF THE MASTER UNIT The configuration and layout of an individual unit may vary from the figure below depending on customer requirements. The actual configuration of each Master Unit can be seen at the configuration list, which is part of the delivery. The basic sections of a Master Unit for multi-user and multi-operator: An optical and combining section consisting of subracks for OTRxs with

combiners, splitters or BTS-connects providing attenuation setting. In the first rack, the optional system alarmboard (SAB) is equipped in this section; depending on the individual customer configuration, optical splitters may also be equipped.

A duplexer unit located behind the optical and combining sections.

A master control unit consisting of the RMC / MMC Plus for supervising the system and alarm forwarding to the OMC as well as an optional monitor and keyboard.

All subracks are connected via an RS485 bus starting at the Master Controller (MC) and continuing from subrack to subrack (see chapter 3.2.2 Duplexer Unit). The last subrack in a cabinet is connected to the first subrack of the next cabinet in the system.

A power supply section; this section usually is located below the RMC600 / MMC Plus controller (see chapter 7.1 Illustrations).

3.2.1. Optical and Combining Section The optical and combining sections are located above the RMC600 of a Master Unit. Depending on the configuration, subracks of 3 HUs, which are intended for 19" rack mounting, are used for two up to four optical transceivers. From the front, the subracks provide plug in space for combiners and splitters, BTS connect (see also chapter 4.4 Commissioning the RF and Optical System) and optical transceivers .

Note: Optical transceiver (OTRx) is a synonym of Subrack Master Unit (SRMU).

Behind each optical transceiver the UL and DL band ports required for levelling the individual bands are located. Thus, the transceiver has to be removed for the levelling procedure (see chapter 4.4 Commissioning the RF and Optical System). Additional space is available for an alarm board, power supply or controller. Duplexers and splitters can be mounted behind the backplane. For subracks containing and supporting the MMC Plus Controller, which will replace all old subracks, the backplane of the subracks is moved 10 U to the left-hand side and the MMC Plus is mounted on the right-hand side, see e.g. figure 3-5 Subrack two OTRxs with MMC Plus and/ or figure 3-8 Subrack three OTRxs with MMC Plus.

3.2.1.1. Subrack Two OTRxs This subrack can manage up to two OTRxs with corresponding equipment. Further-more, there are additional slots of 20 U (1 U = 5.08 mm) where splitters, modems, PSUs or the system alarm board (SAB) can be mounted.

3.2.3. Master Controller

3.2.3.1. General The first master rack in a system contains a master controller for system control, either an RMC600 controller or the MMC Plus controller.

3.2.3.2. RMC600 Controller Locally, system control may either be accessed via the optional monitor and keyboard (see chapter 3.2.6.1 Monitor and Keyboard) or – if this option is not installed – the RMC600 provides RS232 and LAN interfaces for connection (locations see chapters 3.2.3.4 RMC600 Front and 3.2.3.5 RMC600 Rear Side). For further details please refer to chapter 4.5 System Startup and Local Login. The RMC600 will boot automatically two minutes after the respective power supply switch of the Master Unit has been set to on, i.e. when the required voltage has been fed for two minutes. To avoid the two-minute-delay, press the ON/OFF button after having waited for 10 seconds. For details see chapter 3.2.3.4 RMC600 Front. If the RMC600 is delivered separately, ensure for sufficient airflow at the air inlet and air outlets. The RMC is provided with an automatic shutdown function to prevent over temperature. At 70° C the system will send out an according alarm message via modem, and then shut down into standby mode. The software is factory set to initiate a reboot as soon as the temperature has fallen to 40° C. The system can be rebooted locally by pressing the ON/OFF button (see chapter 3.2.3.4 RMC600 Front). or via webpages (see software manual for the ION-M Master Controller).

3.2.3.3. RMC600 Battery Backup (BBU) The RMC600 is equipped with a battery-backup (BBU) to keep up system operation and transmit alarm information in case of power failure. The battery type is Ni-MH, 12 V. When fully charged the battery backup can support system operation for approximately 1.5 hours under normal environmental conditions. The BBU cannot be used to boot the system after a shut down. For this purpose, mains supply via the mains connector (see chapter 3.2.3.5 RMC600 Rear Side) is required. The battery-backup kit comprises a rechargeable battery pack, which has to be replaced after two years of usage at the latest as a preventative maintenance measure. For replacing the BBU, please refer to chapter 6.4 Replacement of RMC600 Battery Backup. Furthermore, an automatic battery refresh is generally factory-set to an interval of ten weeks. This interval may be changed by the customer via software to an interval in the range from 8 – 12 weeks. For details regarding interval setting, refer to the software manual of the Master Controller, which is also part of the delivery. However, it is not recommended to deactivate the refresh function, since this may considerably impair the lifetime of the battery.

3.2.5. Power-Supply Subrack The power-supply subrack comprises the power supply units as well as the mains switches for the unit and the switches, by which the subracks can be switched on or off individually. The system operates on the n+1 redundancy principle, i.e. one (redundant) power supply can be equipped to take over in case of failure of another power supply unit. The power supply units are designed for a hot-plug system, thus it is possible to exchange a power supply while the system is operating. Both AC and DC power supply subracks are either available in 3 HUs with space for up to 4 PSUs equipped or in 6 HUs with space for up to 8 PSUs. The following four different variants of subracks are available:

1. Subrack with 4 PSUs AC, 3 HU (Mains input voltage 115 VAC to 230 VAC /

Output secondary voltage: 12 V DC [for the fan units])

2. Subrack with 4 PSUs DC, 3 HU (Mains input voltage 48 VDC/ Output secondary voltage 12 V DC [for the fan units])

3. Subrack with 8 PSUs DC, 6 HU (Mains input voltage 48 VDC/ Output secondary voltage 12 V DC [for the fan units])

4. Subrack with 8 PSUs AC, 6 HU (Mains input voltage 115 to 230 VAC/ Output secondary 12 V DC [for the fan units])

For PSUs AC the wire-cross section is at least 3 x 1.5 mm2 up to 2.5 mm2.

For PSUs DC the wire-cross section must be chosen according to current consumption of the specific MU and the common rules for electrical installation. The appropriate mains cable to be connected at the terminal block depends on the MU configuration and the resulting power consumption of the unit. Decisively depending on the conduction length and on the laying procedure, the correct cable to be taken must be decided according to the local installation conditions. Master Units without PSU-subracks, such as ION MU with one AC and one DC PSU, shall be equipped with an external certified circuit breaker in the installation. The values for these circuit breakers shall be 6 A in the L-wire for AC and 10 A in the +-wire.

3.2.6.3. Input Power Protection (IPP) Option Optionally for GSM900, GSM1800, and UMTS, the combiners may be equipped with the IPP function (input power protection). The IPP boards, which are an integral part of the combiners, scan each port and measure the input power of the signals for each channel. If the input power exceeds the threshold set by software (for details see separate software documentation), an attenuation of 15 dB will be set for the port to protect the system. Depending on the maximum number of carriers set for a combiner, the input power threshold has to be set accordingly observing the total power specified for the system (see individual band specifications in the “User’s Manual” of the RU).

figure 3-35 Ports of IPP combiner

3.2.6.4. Low Input Power Alarm (Option) For the 800 MHz LMR band, a BTS connect with low input power alarm is available. The BTS connect scans each port and measures the input power for each channel. The alarm is raised if the input power falls below a user-set threshold. The threshold can be set individually for each channel. Additionally, the IPP alarm as described in chapter 3.2.6.3 Input Power Protection (IPP) Option is integrated for the 800 MHz LMR band into this BTS connect.

4.2.5. Rules for Optical-Fibre-Cable Connection Optical signals are transmitted by use of optical fibres. When connecting the fibres according to chapter 4.4 Commissioning the RF and Optical System observe the following instructions.

Note: Care should be taken when connecting and disconnecting fibre-optic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fibre-optic connectors not in use.

In general, optical fibres do not need special protective measures. However, protection against environmental influences e.g. rodents and humidity must be considered. The optical fibre is a single mode fibre. Type is E9/125 with the following minimum requirements. Attenuation: <0.36 dB/km @ 1310 nm / <0.26 dB/km @ 1550 nm Dispersion: <3.5 ps/nm km @ 1310 nm / <18.0 ps/nm km @ 1550 nm The specified bending radius of the optical fibres must not be exceeded. The pigtails for the connection between Master Unit and RU must have a sufficient length. A protection for the feeding into units must be given. The system attenuation of the optical fibres, including the connectors, must not exceed 10 dB. System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fibre, at the in- and output of the device which has to be measured. Fibre cable connectors have to be of the same type (E2000APC) as the connectors used for the unit. The fibre-optic cables are connected to the optical transceiver.

Note: Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors.

Before connecting the fibre cables, follow the procedure below to ensure optimized performance. It is important for these procedures to be carried out with care:

4 Commissioning

Page 57

Remove fibre-optic protective caps.

Do not bend the fibre-optic cable in a tight radius (< 4 cm) as this may cause

cable damage and interrupt transmission.

Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibre-optic cable that will be inserted in the optical connectors on the donor interface box.

Blow out the laser receptacle with clean and dry compressed air to remove

any particulate matter.

Connect the fibre-optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot.

Do not use any index matching gels or fluids of any kind in these connectors.

Gels are intended for laboratory use and attract dirt in the field.

4.4.2. Adjust the BTS / Node B DL Level

Note: To commission the system, the optical transceivers must be removed for levelling. Before, the DC switch of the corresponding subrack (see chapter 3.2.5 Power-Supply Subrack) must be switched to position OFF.

For each band, the DL level has to be measured and adjusted at each transceiver (see illustration below). After the components have been initialized to the Master Unit software, the input level for each band is displayed. The input level depends on the band standard, the number of carriers and the selected optimization. Further information on the input level calculation is provided in the SRMU * / Amplifier chapter software manual of the ION-M Master Controller. Depending on the Master Unit configuration, the input level has to be adjusted at a combiner, a BTS connect or a splitter. These components are normally located in the same subrack as the OTRx.

In case of a non-dedicated application, desensitization of BTS or Node B should be considered. When all provided levels have been adjusted, reinstall the optical transceiver. When all transceivers of a subrack have been reinstalled, do not forget to switch the DC switch of the according subrack back to position ON. To remove the transceiver, loosen the four captive screws (please see chapter 4.4.1 Setting the Transceiver Address) by which each transceiver is fastened to the subrack. Use the grip to pull the transceiver out.

For levelling, plug in the levelling adapter* that is part of the delivery at the position of the transceiver and fasten it with the two captive screws.

Connect a spectrum analyzer to the band connectors of the adapter. The

adapter connectors are SMA female, thus the spectrum analyzer requires SMA male. * If no levelling adapter is available, connect a spectrum analyzer to the DL band ports at the

backplane of the subrack (location and configuration see following illustrations on the configuration of band ports). The band ports are SMS male connectors, thus the spectrum analyzer requires SMS female.

Connect the base station / Node B (see also chapter 4.2.4 BTS / Node B

Connections) one after the other at the port connectors of the respective band combiner – or, depending on the individual customer configuration, at the connectors of the BTS connects (see chapter 3.2.1.1 Subrack Two OTRxs), splitters or modem (see chapter 3.2.6.10 External Modem) – and adjust the DL level by means of the corresponding stepless attenuators (see following description) until the required level (according to the calculated values from the Master Unit software) is reached.

At the three ports of the levelling adapter different bands for the different OTRxs can be measured. The position of bands is described in chapters 4.4.3 to 4.4.6.

For detailed information on alarms and troubleshooting please refer to the software manual of the Master Controller.

6. MAINTENANCE

6.1. HOT SWAPPING UNABILITY

WARNING: The ION-M MU OTRx is NOT capable of hot swapping, i.e. system components should not be removed and replaced without powering down the relevant subrack BEFORE. Although, hot swapping does not cause any damage to the OTRx, however, we recommend this to prevent any undesirable effects (i.e. settings of the software may be corrupted and possible system instabilities).

So PRIOR to replacing components, first power down the subrack that hosts the relevant OTRx by disconnecting it from mains. After replacement, power-up the subrack again.

Note: If for any operational reason, an OTRx has to be replaced without

powering down the hosting subrack, make sure the configuration is still correct and that there have been no modifications after the replacement. For new hardware modules to be detected by the software, auto setup needs to be executed. For detailed description please refer to the latest version of the corresponding software manual for the ION-M Master Controller.

6.2. RMC600 WARRANTY CONDITIONS It cannot be avoided to break the warranty seals of the RMC600 to perform preventive maintenance measures on the built-in accumulator or to increase the memory size of the equipped SODIMM module with 256 MB (KVR133X64SC3/256) to SODIMM module with max. 512 MB (KVR133X64SC3/512). The preventive maintenance actions described in this manual shall not void the warranty for this equipment. Thus, from this release of the manual onwards, a breaking of the warranty seals of the RMC 600 for user-conducted maintenance described in the following does not void the warranty as agreed in the customer's contract.

6.6. MAINTENANCE CYLE OF MMC PLUS BATTERY BACKUP

6.6.1. General and Basic Functions of the MMC Plus Battery Pack A mains-power failure (+12 V) will be indicated by the "mains power supply failure" alarm message in the ION-M Master Controller software (Current Alarm Status - Supervision - Active Alarms and Supervision - Alarm Status). In case of a mains failure the MMC Plus battery buffers MMC Plus operation. Under optimum battery-charge conditions (i.e. with battery in good state and fully charged), the battery pack will be able to buffer short mains failures for up to 2 minutes. When a mains failure lasts longer than 2 minutes, a shutdown of the Master Controller will automatically be started. When the battery-charge condition is not optimal, (i.e. the battery pack has not been charged entirely or is not new) this backup time of maximum 2 minutes will be reduced accordingly and the Master Controller starts the shutdown earlier than after 2 minutes. The following time-response diagram depicts when and how the MMC Plus carries out a shutdown (an interruption of mains power for a few seconds causes no shutdown of the MMC Plus).

6.6.2. Reasons why the Battery Pack has to be Replaced

Batteries have only a limited lifetime which is mainly affected by long-term impact of environmental temperature.

The battery has to be replaced in order to get complete functionality of the battery and to safeguard reliability of the unit.

A system crash due to mains failure of the Master Controller despite having sufficient time for charging (> 2 hours) indicates that the battery is at the end of its life.

Ageing of the battery contributes to a loss of capacity. => When the capacity of the battery is not sufficient to bridge short mains

failures, it must be replaced.

6.6.3. Restrictions on Battery Operation Warning: When two mains failures appear in short succession, it may happen that

the battery did not have enough time to be fully charged again and consequently to buffer the next mains failure, either. As the battery is not charged enough to back up the default time, the back-up time will be shortened as a result. During a mains failure the battery can keep the MMC Plus in operation only for a limited period of time. When a mains failure lasts longer, the Master Controller will be shut down.

Note: There is no hard and fast rule for replacing the battery as the lifetime of the battery depends on many criteria, e.g. on temperature, frequency of usage, location and on the individual type of the battery. Though to state a rough guideline for replacing the battery: To play save the battery should be replaced after 2 years of usage, but – depending on environmental influences - after 4 years at the latest. However, should the battery be (over)stressed or in case of system crashes, the battery has to be replaced. As a general rule we recommend to replace the battery after 3 years of usage.

In the following, an example is given: For applications in the temperature-controller room where the temperature range varies between 20°C to 40°C (with an average of 25°C and an average humidity of 20% to 60%) and assuming that a mains failure < 2 minutes occurs approx. 10 times a month (short interruptions in the range of some milliseconds or seconds can be disregarded), the battery should be replaced every 3 years of usage. In case of mains failures > 2 minutes (=> system will shutdown) occurring 2 - 3 times a month, the battery can also be replaced after 4 years of usage.
