2.2 Radio Interface Unit (RIU)
The RIU is an operator dedicated unit that interfaces to up to three BTS sources and
automatically adjusts the signal output according to changing environmental conditions in order
to provide optimal coverage for the site. The RIU is remotely monitored and managed.
Each RIU can support up to three BTS Conditioner (BTSC) sub-modules, where each sub-
module provides interface to a BTS or BDA of
the same type of service
.
Each RIU can be connected to
Base Units.
Additional BUs can be supported by using splitters and combiners connected to the front panel
Expansion connectors.
The following figures shows an RIU with three BTSC sub-modules.

ATTENTION
The RIU is factory set to 0dB gain on the uplink and downlink. In order to operate
properly, an ADJUSTMENT process is required in the field.
Any unused input and output connectors MUST be terminated with 50 ohms –
otherwise the ADJUSMENT procedure results may be affected.

2.3 MA Base Units
The BUs (Base Units) perform RF to optical conversion of the signal on the BTS/BDA side. Each
can support up to two services (provided by the same operator). Two models of MA BUs are
available: four-port unit – supporting four RHUs, and eight-port unit supporting up to eight
RHUs. The RHU models correspond to the services supplied through the BUs.
The BU (and all the corresponding remote units) may be remotely monitored and managed via
the MA NMS (Network Management System).
The BUs are usually installed in the telecom room adjacent to the BTS/BDA signal source. RF
ports on the rear panel provide interface to the BTS side (through connection to RIU or passive
interface), while optic ports on the front panel provide interface to the RHUs (Remote Units).
This following sections describe the MA BU front and rear panels, including indicators and
connectors.

2.3.1.2 BU Rear Panel
The BU rear panel contains the RF, Alarms, NMS and power connections. Note that there are
two uplink and two downlink RF connections to the BTS side (to an Interface Box or RIU) - each
individual uplink and downlink connection corresponds to a four-port BU element. For a fourport BU, one uplink and one downlink port is connected; for an eight-port BU, two uplink and
two downlink ports are connected.
For systems that include MA 430 controllers, the RS 485 port is connected to the MA 410/430
controller to enable remote monitoring and management of the BU from a central location. For
systems without remote management, the Alarms dry-contact connector pins can be connected
to the BTS to provide alarms functionality.

3.1 Infrastructure Preparation
This following installation rules are based on the assumption that site survey and installation
planning (
including power requirements
) have been completed.
3.2 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. This includes the MA 850, 802.11 Access Points, cabling and other voice
service distribution systems that are relevant to the specific installation.
3.3 Coaxial Cable Connections
3.3.1 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). Each length of cable from the risers to each antenna must be concealed above
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.
27
Page 18
MA 1000 Installation and Configuration Guide
3.3.2 Fiber Optic Rules
• Use only single mode fiber for indoor applications.
• 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.
3.3.3 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.
• 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 RHUs in the
remote communication rooms
• Terminate all unused RHU and RIU ports with a 50 ohm load

3.3.6 Power Safety Instructions
SAFETY WARNINGS
• When installing or selecting the power supplies:
• Be sure to disconnect all power sources before servicing.
• Battery replacement in units - only the MA 410/430 controller has batteries. MA
410/430 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 – use only the power cords supplied with the units
• Install external over-current protective devices for the system according to the
requirements described in section
3.3.9.
