2 Functional Description   Page 11 2. FUNCTIONAL DESCRIPTION 2.1.  PURPOSE  Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) 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 and several Remote Units. The number of the Remote Units depends on the hardware and software configuration. The Remote Units are connected to the Master Unit with optical links. The optical loss must be less than 10 dB inclusive optical couplers or splitters.  The Master Unit is the connection to the base transceiver stations. The configuration of a Master Unit depends on the number of the Remote Units and the frequency range.   WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the UL, a wavelength within 1540 nm - 1562 nm is used. For the DL, a wavelength of 1310 ±20 nm is used. The maximum output power for the UL and DL is 5.7 mW.  2.2.  THE ION-M80/90/19P  The fibre-optic distribution system is designed for LMR and PCS services. Up to three bands (LMR800, LMR900 and PCS1900) can be transmitted. Each fibre is able to serve up to four Remote Units and to operate up to four providers. One Master Unit can operate up to 124 Remote Units point-to-point plus 32 x 4 Remote Units in a cascaded way.  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 Remote Units can be connected to the Master Unit via only one fibre and optical couplers.  The unit also provides a transparent link in the frequency range from 2496 MHz to 2690 MHz, which can be used e.g. for WiMAX applications in this frequency range.  The Remote Unit ION-M80/90/19P (Intelligent Optical Network; MMR) is connected to a central Master Unit via optical-fibre lines. Specific customer designs for lamp pole or wall mounting are available. Thus, the system provides many advantages in view of easy site acquisition.

Turn off mains* power before connecting the power cord at the Remote Unit, then, engage mains again.  *  Mains power must be interrupted with an external mains breaker. For the mains breaker, observe the following recommendation: 120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC service is needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt service. For the DC power supply, observe the local regulations of the DC service provider.
3 Commissioning   Page 233.3.  CONNECTION OF THE ANTENNA CABLES  The Remote Unit has N-type antenna connectors. For its location please refer to chapter 3.2.2 Connections. For mounting the cable connectors, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications.  For the selection of cable and antenna it should be considered that, on the one hand, a cable with higher loss is less expensive but, on the other hand, it impairs performance.  Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 available from the Andrew e-catalog. Do NOT use your hands or any other tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit.   To minimize passive inter-modulation (PIM) distortion, attention has to be paid to the physical condition of the connector junctions. Do not use connectors that show signs of corrosion on the metal surface. Prevent the ingress of water into the connector. Attach and torque the connectors properly.  3.4.  OPTICAL-FIBER-CABLE CONNECTION - RULES  Main optical system parameters:  Fiber:    Single mode fiber, type is E9/125 µm    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    Fibre-cable connectors E2000APC8°  ION-M system:    The specified bending radius ( < 4 cm) of the optical fibers must not be exceeded.    The pigtails for the connection between Master Unit and Remote Unit must have a sufficient length. A protection for the feeding into units must be given.     The system attenuation of the optical fibers, including the connectors, must not exceed 10 dB.
User’s Manual forRemote Unit ION™-M80/90/19P Page 24  MF0133ABA.docSystem 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 fiber, at the input and output of the device which has to be measured.  Fiber-System Installation:  Fiber-cable connectors have to be of the same type (E2000APC8°) as the connectors used for the unit. The fiber-optic cables are connected to the optical transceiver.    Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors.  Before connecting the fiber cables, follow the procedure below to ensure optimized performance. It is important for these procedures to be carried out with care:  ¾  Remove fiber-optic protective caps.  ¾  Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission.  ¾  Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fiber-optic cable that will be inserted in the optical connectors on the donor interface box. Use a fiber end-face inspection tool to scan both, the class fiber and its surrounding area.   ¾  Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.  ¾  Connect the fiber-optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot.  ¾  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.  ) Note:  Care should be taken when connecting and disconnecting fiber-optic cables - use the connector housing to plug or unplug a fiber. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fiber-optic connectors not in use.
3 Commissioning   Page 25Cleaning Procedure for Fiber-Optical Components:   Any contamination in the fiber connection results in additional optical transmission loss which could cause whole system failure. It is thus recommended that every fiber connector be inspected and cleaned prior to mating. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber-optic connection.   When you clean fiber components, always complete the following steps carefully: 1.  Turn off the ION system (laser sources) before you inspect fiber connectors.  Never look into a fiber while the system lasers are on!  2.  Check the connectors or adapters with a fiberscope before cleaning.  3.  If the connector is dirty, clean it with a lint-free wipe (dry cleaning).  4.  Inspect the connector.  5.  If the connector is still dirty, repeat the dry cleaning technique.  6.  Inspect the connector.  7.  If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning) followed immediately with a dry clean in order to ensure no residue is left on the endface.  8.  Repeat steps 5 through 7 until endface is clean.  Note: For a more detailed description please refer to:  http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml

EXTERNAL ALARM INPUTS AND OUTPUTS  G1038Z0  G1038Z0  figure 4-1 Flange connector, 5 poles  figure 4-2 Flange connector, 7 poles  The alarm outputs (open collector output 5 V / 1 mA) are normally low. In case of an alarm they are high active (5 V). They can be used to monitor alarms with an external alarm indicator.  The +28 V pin (for its location see figure 4-2 Flange connector, 7 poles) is protected by a 500 mA thermoswitch. In case of exceeding this current between pin 7 and GND and/or in case of a failure of the VSWR module, the thermoswitch turns into a high-resistive status. In this case no fuse needs to be replaced. Just wait a few minutes until the thermoswitch reaches the normal operating temperature again.  ) Note:  The manufacturer / supplier of this system accepts no liability for damage caused by equipment connected to external outputs or by effects from such equipment.  As accessory equipment the alarm kit (see chapter 6.3 Spare Parts) is available to connect external devices to the external alarm inputs and outputs.
User’s Manual forRemote Unit ION™-M80/90/19P Page 36  MF0133ABA.docWith the external alarm inputs it is possible to monitor the status of connected devices, e.g. a UPS, via software. All alarm inputs are normally high (5 V) without connection. The polarity (high/ low) can be set via the software at the Master Unit (for details please see according software manual).  The device to be monitored must be connected so that the alarm contacts will be closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with common ground.
