  MobileAccessGX Installation and Configuration Guide   3  1.2  System Architecture MobileAccessGX  provides  a  complete  solution  consisting  of  GX  remote  units at  the  remote locations, and  head-end elements, which are shared with any existing  or new MA1000/MA2000 deployment. In the downlink, at the head-end, the BTS or BDA signal is conditioned by the  RIU, ensuring a constant RF level. The conditioned signal is then converted by the  FT-350 OCH (Optical Control Hub) to an optical signal for transport over single-mode fiber to the GX remote units, which are located at the remote locations. In the uplink, the process is reversed. The SC-450 Controller enables  local  and  remote  management,  as  well  as  controls  all  GX,  MA1000  and  MA2000 elements from a single, centralized location. The  MobileAccessGX  Remote  Unit  consists  of  a  uniquely  designed,  non-obtrusive  unit  that includes all of the required RF, F/O and power interfaces. The GX product supports four service types:  CELL/PCS/LTE  700/AWS  –  each  unit  supports  up  to  3  bands,  whereas  the  supported bands  depend  on  model  (see  Appendix  B:  Ordering  Information).  All  mobile  services  are distributed  through  service/band  dedicated  RF  connection  ports  over  antennas installed  at  the remote locations.    Figure 1-2. System Architecture    NOTE:  When  MobileAccess  GX  unit  is  deployed  with  units  supporting  the  800MHz  band,  an external filter is needed to be installed on the GX to avoid the disturbance between the 800MHz DL and the 850MHz UL frequencies.
  MobileAccessGX Installation and Configuration Guide   4  1.2.1  Signal Path 1.2.1.1 SISO Signal Path On the DL, combined signals  up  to  tri-band from the OCH converted  into optical signals. Then the optical signals are transmitted to the RU via optical fiber. The Optical TX/RX Module of RU converts  the  DL  optical  signals  into  RF  signals.  After  filtering  signal  for  each  band  and amplification, the signals are transmitted at the output port (700MHz/CELL850/PCS/AWS) to the service antenna.    On the UL, the signals transmitted by the mobile are converted into optical signals, and then via the UL optical fiber. The signals are transmitted to OCH, which then converts the optical signals back to RF signals.    The optical DL and UL signal are transmitted in a single optical fiber based on WDM technique.  OCH GXRIU To DAS antennasF/OTo signal source RF Figure 1-3. GX Functional Block Diagram – SISO Configuration  1.2.1.2 MIMO Signal Path In MIMO system, the principle is similar to the single system. In MIMO, Dual-DL and dual-UL are required,  e.g.  700LTE /  AWS.  So  two  GX  remote  units  are  connected  to  the  OCH. A  pair  of optical fiber in same length is needed for the remote units to ensure the same time delay to both units.

  MobileAccessGX Installation and Configuration Guide   8  22  SSyysstteemm  IInnssttaallllaattiioonn  This chapter describes the installation procedure for the MobileAccessGX Remote Units. 2.1  Site Considerations   The distance between the  GX service antenna and  the coverage area should correspond to LOS (Line of Sight) requirements for maximum coverage area.   The maximum fiber path loss is 6dB.   The  system  delay  of  the  optical  system  must  be  taken  into  consideration  when  there  are neighboring BTS sites overlapping in coverage.   When the GX  remote unit  is deployed with  units supporting the 800MHz band, an external filter is needed to be installed on  the GX to avoid the disturbance between the 800MHz DL and the 850MHz UL frequencies. See section Error! Reference source not found..  In  the  MIMO scenario,  two remote  units  shall use  a  pair  of optic  fiber  for  each  one.  This ensures to avoid the system delay difference between two units.  2.1.1  Installation Location  Mounting surface shall be capable of supporting the weight of the equipment.   In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize interference from electromagnetic sources such as large electrical equipment.  2.1.2  Environmental   Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in locations having stable temperature and unrestricted air-flow.  The  installation  location  for  the  system  should  be  well  ventilated.  The  equipment  has  been designed  to  operate  at  the  temperature  range  and  humidity  level  as  stated  in  the  product specifications  that  of  temperature  ranges  from  -40~55oC  and  the  relative  humidity  is  at  most 85%.  2.1.3  Powering  The power supply unit (PSU) provides power to all modules within the equipment. Depending on the product variant, it is recommended that the PSU operates on a dedicated AC circuit breaker or fused circuit.  2.1.4  Grounding Requirement  Verify  that  the  equipment  has  been  well  grounded.  This  includes  antennas  and  all  cables connected to the system. Ensure lightning protection for the antennas is properly grounded.
  MobileAccessGX Installation and Configuration Guide   9  2.1.5  Cable Routing  Ensure all  cables,  e.g.  power cable, feeder  cable, optic  fiber, commissioning  cable,  connecting are properly routed and secured so that they are not damaged.  2.1.6  Manual Handling  During  transportation  and  installation,  take  necessary  handling  precautions  to  avoid  potential physical injury to the installation personnel and the equipment.  2.2  Installation Requirements  Working  space  available for  installation  and  maintenance  for  each mounting  arrangement. Ensure unrestricted airflow.   Ensure grounding connector is within reach of the ground wire.    Ensure  a  power  source  is  within  reach  of  the  power  cord  and  the  power  source   has sufficient capacity.   Where appropriate, ensure unused RF connectors are terminated.    Do  not  locate  the  equipment  near  large  transformers  or  motors  that  may  cause electromagnetic interference.   Reduce signal loss in feeder cable by minimizing the length and number of RF connections.   Ensure the equipment will be operated within the stated environment (refer to datasheet).    Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.    Observe handling of all cables to prevent damage.   Ensure same length for a pair of optic length for units in MIMO scenario. 2.3  Fiber Optic Rules Attention! Please refer to the Laser Safety section in the document Preface.    Fiber  optic  cables  require  proper  handling.  Do  not  stretch,  puncture,  or  crush  the  fiber cable(s) with staples, heavy equipment, doors, etc.   Always  maintain  the  minimum  bending  radius  specified  by  the  cable  manufacturer.  The minimum bend radius is  usually  10  times the  cable's  outer diameter. In the case of single optical fiber that is not in a cable, the minimum bending radius to be observed is 30mm.  WDM, Wave Division Multiplexing, units require SMF  Use SC/APC connectors (green color) 8 deg only.  Use minimum splicing/connectors to achieve minimum losses on the fibers.  Use precaution while installing, bending, or connecting fiber optic cables.  Use an optical power meter and OTDR for checking the fiber optic cables.  Make sure the environment is clean while connecting/splicing fiber optic cables.   All fiber optic connections should be cleaned prior to attaching to termination points using a dry cleaning device (i.e. Cletop or equivalent).  Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are terminated.  Check the Fiber Optic connections.   Pay  special  attention  while  connecting  the  SC/APC connectors  -  you  must  hear  the  “click” when the connection is made.

  MobileAccessGX Installation and Configuration Guide   33  44  PPrroovviissiioonniinngg  tthhee  MMoobbiilleeAAcccceessssGGXX  Once  the  required  physical  connections  have  been  completed,  the   GX  unit  is  automatically detected (auto-discover) by the SC-450 and can be remotely monitored and managed. The MobileAccessGX Remote Unit is centrally managed via the MobileAccess SC-450 Controller.  Note  that  MobileAccessGX is  not  connected  directly  to  the  controller.  It  is  connected  to  the Optical  Control  Hub  (OCH)  (that  is  connected  to  the  controller).  Thus,  the  controller  mo nitors views and manages the GX via the OCH to which the GX is connected. Note: The provisioning procedure consists of two simple steps: assigning the unit name (Module Info tab) and clicking the Adjust  button (Adjustment tab). Additional configuration options are available as well. Each  GX  unit  can  be  managed  via  several  dedicated  panes  that  are  accessed  by  clicking  the relevant GX item in the SC-450 Topology Tree. 4.1  Accessing GX Management Options To access the MobileAccessGX management options In  the  Network  Topology  tree,  expand  the  relevant  Controller  item,  expand  the  relevant OCH  (to which the GX is connected) and click on the GX. The GX alarms and management tabs appear.  Figure 4-1: Example of GX Unit Module Info Tab    GX item Host OCH GX Alarm status Four management tabs Controller
  MobileAccessGX Installation and Configuration Guide   34  The  GX  Alarms  are  continuously  displayed  (to  the  left  of  the  tabs).  The  monitoring  and configuration options are distributed over four tabs:  Module Info - device version and identification definitions   RF Parameters – service control options.  RF Adjustment – provides the adjustment options.  Service Alarms – used for masking redundant alarms 4.2  Basic Setup Procedure To perform basic setup 1.  Verify that the alarms show green in the following tabs:  GX Cabinet Alarms – displays system level alarms  Figure 4-2: Example of GX Alarms The following table provides a description of the device alarms shown above. Alarm Description Door Open Enclosure door open Optical Link Alarm Low optical level from BU (link level < 56) Fans Alarm Faulty fans Service 1/2/3 Summary of all port x / PA x monitored parameters displayed in the Service Alarms sub-tab Overall status Calculated  according  to  its  active  alarms  – corresponds to highest alarm level detected.

  MobileAccessGX Installation and Configuration Guide   36  2.  Mask irrelevant alarm conditions, in both tabs via the Modify button, to avoid having them reflected overall status of the GX unit (displayed in the GX Alarms area). For Example In the example below, the GX Alarms dialog shows the alarm response if the Service 2 DL Output  Power  Low  alarm  is  NOT  masked  (enabled).  In  that  case  the Service  2 and Overall Status will be RED indicating a fault.      If the Service  2 alarm is MASKED (Disabled), then the LED for the alarm will be RED; but, the corresponding Service alarm in GX Alarms area will be GREEN – showing NO Fault. Note:  The  Overall  Status  alarm  will  only  show  green  if  all  of  the  generated  alarms  are masked (or if all alarms are green).                                        In the figure above the alarm condition for (Service 2) “DL Output Power Low” actually exists, while the masking prevents this condition from affecting the  overall status of the service and therefore the Service 2 LED in GX Alarms area is green.   Unmasked alarm RED - Unmasked alarm reflects on corresponding Service alarm and Overall Status Masked alarm GREEN - Masked DL Output Power Low alarm (for Service 2) alarm does not reflect on corresponding Service alarm in GX Alarms area.

Appendix B: Ordering Information   MobileAccessGX Installation and Configuration Guide   43  AAppppeennddiixx  CC::  SSiittee  PPrreeppaarraattiioonn  This  following  installation  rules  are  based  on  the  assumption  that  site  survey  and  installation planning (including power requirements) have been completed.  Installation Requirements The infrastructure preparation consists of two main phases: A. Floor  Planning:  Planning  the  distribution  of  the  antennas  on  each  floor  to  provide  the required coverage.  B. Telecom  Closet  Planning:  Planning the layout  of  the  devices and  cables in  the telecom closet or shaft.  Coaxial Cable Connections General Cable Installation Procedures Observe the general cable installation procedures that meet with the building codes in your area. The  building  code  requires  that  all  cabling  be  installed  above  ceiling  level  (where  applicable). The length of cable from the risers to each antenna must be concealed above the ceiling.  The cable must be properly supported and maintained straight using tie-wraps, cable trays and clamps or hangers every 10 feet (where practical above ceiling level). Where this is not practical, the following should be observed:  The minimum bending radius of the supplied ½” coax cable should be 7”.  Cable that is kinked or has a bending radius smaller than 7” must be replaced.  Cable  runs  that  span  less  than  two  floors  should  be  secured  to  suitably  located mechanical structures.  The cables should be supported only from the building structure.
Appendix B: Ordering Information   MobileAccessGX Installation and Configuration Guide   44  Fiber Optic Rules  Either single mode or multimode fiber can be used with MobileAccess2000M products, while MobileAccess2000 products can only be used with single mode fiber.  Only Multimode fiber, 50/125 or 62.5/125um complying with ANSI/TIA/EIA-568-B series, EN50173-1 or  ISO/IEC  11801  can  be  used.  The  fiber  length  can  be  up  to  300  meters assuming the following qualifications:  All fiber in a given length of fiber must be of the same core diameter.   All Bulkhead adapters must be Single mode SC/APC (Green) adapters.   All  terminations  cross  connections  or  patches  must  be  direct  fusion  splice  or MobileAccess specified patch cords listed below.  900 microns pathcord for splicing, 2 Meters, 2xSC/APC Diamond p/n ENC/1045341   Beige boots, 62.5/125/900 MA# 500001057 Diamond p/n ENC/1045340   Black boots, 50/125/900 MA# 500001058  Zipcord patchcord, 4xSC/APC, 50/125/900/2000/4500 micron Diamond p/n ENC/1045342   Black/Brown boots, 1Meter MA# 50000105 Diamond p/n ENC/1045343   Black/Brown boots, 3 Meter MA# 500001060  Zipcord patchcord, 4xSC/APC, 62.5/125/900/2000/4500 micron Diamond p/n ENC/1045344   Beige/Brown boots, 1 Meter MA# 500001061 Diamond p/n ENC/1045345   Beige/Brown boots, 3 Meter MA# 500001062   Use only 8-degree SC/APC connectors (green color).  Use only fusion splice for connecting two fibers.  Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB).  Use precaution while installing, bending, or connecting fiber optic cables.  Use an optical power meter and OTDR for checking the fiber optic cables.  Make sure the environment is clean while connecting/splicing fiber optic cables.   All  fiber  optic  connections  should  be  cleaned  prior  to  attaching  to  termination  points using a dry cleaning device (i.e. Cletop or equivalent).  Fiber  connector  protective  caps  should  be  installed  on  all  non-terminated  fibers  and removed just before they are terminated.  Verify the Fiber Optic connections. You may use the Optical Test Procedure described at the end of this manual.  Pay special attention while connecting the SC/APC connectors  - you must hear the “click” when the connection is made.  RF Rules  Use coax RG223, 50ohm, male-to-male N-type for RF connections from  the  BUs to the BTS/RBS and to the RIU.
Appendix B: Ordering Information   MobileAccessGX Installation and Configuration Guide   45   When using the MobileAccess system in an environment in which other indoor coverage systems are installed, it is recommended (where possible) that the antennas are placed at least two meters apart   When  bending  coax  cables,  verify  that  the  bending  radius  does  not  exceed  the  coax specifications.  Use wideband antennas supporting a range of 800Mhz to 2500Mhz   Use  a  VSWR  meter  (i.e.  Site  Master  or  equivalent)  for  checking  coax  cables,  including the antennas.  (<2).  The  VSWR  must  be  measured  prior to  terminating  the RUs  in  the remote communication rooms  Terminate all unused RU and RIU ports with a 50 ohm load  Power Consumption, Connections and Power Supplies Power Safety Instructions    SAFETY WARNINGS  When installing or selecting the power supplies:    Be sure to disconnect all power sources before servicing.  SC-450 Controller lithium type battery should only be  replaced by MobileAccess service personnel. Risk of exploding if battery is replaced by an incorrect type.  Dispose of used batteries according to the instructions.  Calculate  the  required  power  according  to  the  requirements of  the  specific  installation and then determine the configuration of the power supplies. The required DC cables will then be determined by the selected PS configuration.  Use only UL approved power supplies   AC and DC power supply cables – only use the power cords supplied with the units   Battery replacement in units  - only the SC-450 controller has batteries. These should be replaced (when necessary) only by MA Service Personnel.  Install  external  over-current  protective  devices  for  the  system  according  to  the requirements.

Appendix B: Ordering Information   MobileAccessGX Installation and Configuration Guide   46  Circuit Breakers Install fuse protections for the system according to the following criteria:   The following system  elements require  external fuse  protection:  RIUs,  BUs,  and  SC-450 Controllers.  Referring to Table 4-2, calculate the required fuse protection.   Example:  a  set  of  three  elements  consisting  of  a  BU,  RIU  and  SC-450  controller requires a 2A circuit breaker.  Types of Power Supplies MobileAccess  supplies  various  power supplies  that  can  be  installed  in  a  rack  o r  mounted  on  a wall, depending on your configuration.   Installation Conventions Some of the basic installation conventions are listed below for the MA 2000 system:  Base  Units –  are  usually  concentrated  in  the  same  location,  most  often  in  the  main communication room.   Remote  Cabinet/Lite  –  usually  placed  in  the  communication  shaft  or  closet  of  a corresponding  floor  so they  can be easily located.    Each cabinet  (or  MA2000-Lite) can typically cover a floor of up to 30,000 sq ft.   Fiber  optic  cable  -  bundled  fibers  are  terminated  into  the  Base  Units  in  the  main communication  room.    The  fibers  are  then  routed  to  each  coverage  locations  where individual  fibers  terminate  into  splice  boxes.  The  splice  box  couples  the installed  fiber into  the  remote  units.    Enough  spare  fibers  should  be  installed  to  take  into  account future expansion of the system.   For  example,  for  three  remote  units,  six  fibers  are  required.  However,  to  allow  for  futur e expansion, it is recommended to install additional optic fibers to be connected to additional RUs.   Continued on the following page...
Appendix B: Ordering Information   MobileAccessGX Installation and Configuration Guide   47  The following figure illustrates fiber optic routing to Remote Cabinets.  Figure 4-7. Illustration of Fiber Optic Routing   For  remote  power  supply  configuration  -  cable bundles are routed from the main communication  room  and  individual  wire  pairs  are  terminated  into  the  power  feed  of individual units.   By providing  power  from  a  single  distribution  point, maintenance  can be  reduced  and  UPS backup can  be easily  provided. The maximum  distance from  the  source  to  the  termination spot is 1000 feet using 18 gauge wires.   In many locations local codes do not require power to be run through conduit if 100 watts or less  is  used.    Please  consult  the  regulations  in  your  local  jurisdiction  prior  to  deploying remote power.  When power cables require distances greater than 1000 feet 14 or 16 gauge wire may be used.     On each floor - the antennas are connected to the Remote Cabinet or MA2000-Lite system using coax cables.
