1 Introduction MobileAccess2000 QX (QX) is a member of the MobileAccess2000 family. It is a compact, modular, cellular indoor coverage remote unit supporting up to four services (currently, CELL/PCS, LTE and AWS). 1.1 Key Features and Capabilities All services are received from the head-end, over a single optic fiber and reconverted to RF for convergence and distribution over a common DAS antenna infrastructure. • Multi-Service Platform - Supports up to four services.
1.2 System Architecture The QX and SCU-F are located at the floor level remote end. QX receives RF over optic service signals from the head end, reconverts the signals to RF over copper, adjusts them to the required level and outputs each service to dedicated interfaces. The signals are combined by the SCU-F (along with services from other QX units) and distributed over a common DAS (Distributed Antenna System) infrastructure.
• RF to Optic converter unit – this can either be a Base Unit (BU) or an Optical Control Head End Unit (OCH), where the OCH is QX model specific. These are wideband units that convert the RF Downlink (DL) signals from the RIU into optical signals for routing over single or multi-mode fiber optic cabling (SMF/MMF) to/from the QX units located at the remote locations up to 2Km away.
1.3 QX Interfaces and Internal Modules 1.3.1 QX Interfaces This section provides a full, detailed description of the QX unit and relevant interface connections (Table 1-2) and LED indicators.

1.3.2 QX Main Internal Modules The QX main components consist of the following internal modules: • Remote Hub Unit (RHU) – service specific unit, supports two voice services, converts the optical signals received from the BU/OCH to RF signals (and vice versa) and routes them to the coax antenna infrastructure (via the Four Port Service Combiner Unit – SCU-F).
1.4 SCU-F Interfaces The SCU-F is a passive unit which interfaces to the QX RF service ports and internal AMU module and to the DAS infrastructure. All of the interfaces are located on the front panel (shown in Figure 1-6). DB-15 port to QX DB-15 port Antenna Ports 1-4 SCU-F Front Panel Low Band (1-4) ports; High Band (5-8) ports Figure 1-6 Table 1-4.
2 Installation Guidelines 2.1 Infrastructure Preparation This following installation rules are based on the assumption that site survey and installation planning (including power requirements) have been completed. 2.2 Installation Requirements The infrastructure preparation consists of two main phases: Floor Planning: Planning the distribution of the antennas on each floor to provide the required coverage.
x 2.3.2 RF Rules • 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).
2.4 Fiber Optic Rules • Either single mode or multimode fiber can be used with QX products. • 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.
2.5 Power Consumption, Connections and Power Supplies 2.5.1 Power Safety Instructions SAFETY WARNINGS When installing or selecting the power supplies: • It is required to install a circuit breaker of 7.5A for the DC supply circuit. • Be sure to disconnect all power sources before servicing. • Calculate the required power according to the requirements of the specific installation and then determine the configuration of the power supplies.
3 System Installation The following sections provide an overview of the installation procedure for the QX and an SCU-F unit. Note: The QX must be installed with the SCU (in rack installations - preferably below the SCU).
3. Verify that all supplied items have been received for the QX (see Table 3-1) and Table 3-2). Table 3-1: Package Contents Kit Item P/N Description QTY.

3.3 Inserting an RHU/AO Module in to QX Chassis The QX chassis and Remote Hub Unit (RHU) and Add-On (AO) modules are provided separately, whereas the modules must be inserted in to the chassis. This requires opening the QX chassis front panel door and inserting the modules into their respective slots. The RHU/AO modules are hot swappable and can be inserted either before or after the system installation. To insert an RHU/AO Module 1. Open the QX door, by unscrewing the two captive screws.
Positioning New Module in Designated Slot Figure 3-3 4. Push the module all the way back until it “clicks” in to the chassis backplane. 5. Close ejectors and close both captive screws to secure the module in place. Refer to Figure 3-4. 6. For each Add-On module, connect the internal DC power feed to the module DC power connector. Refer to Figure 3-4. Securing Module in Slot and DC Connections Figure 3-4 NOTE: The RHU service module does not have an internal power feed connection.
3.4 Mounting 3.4.1 Rack Mount Installations 3.4.1.1 Plan the rack installation NOTE: The unit can also be wall mounted using dedicated brackets (ordered separately). For wall mounted units – it is recommended to install the service modules first. 1. Verify that the height of the rack can support QX unit being installed, as well as additional equipment, SCU-F, AC or DC power, and space for the broadband coax connection. Also consider room for future expansions. 2.
3.4.1.2 Rack Installation Safety Instructions Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation. • Only trained and qualified personnel should be allowed to install or replace this equipment. • Verify that ambient temperature of the environment does not exceed 50°C (122°F) • To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack from the bottom to the top.
