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-M7P (INTELLIGENT OPTICAL NETWORK; MMR)
The fibre-optic distribution system is designed for LTE 700 MHz services. Each fibre
is able to operate services of up to four providers. One Master Unit can operate up to
124 Remote Units.
An auto-levelling function for compensating different fibre losses and a
comprehensive supervision concept are implemented. Auto-levelling in the DL works
with optical power measurement, in the UL a 10.7 MHz signal is used for measuring
the optical loss.
The Remote Unit ION-M7P 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.

Page 14 MF0143A8A.doc
2.3. COMPONENTS OF THE ION-M7P REMOTE UNIT
2.3.1. Fan-Protection Kit
In order to protect the fan unit (e.g. against rain), a protective cover to be mounted
over the air inlet is delivered with the unit. For more details see chapter 3.1.4
Mounting of Fan Protection.
Mounting of the fan-protection kit is only mandatory for outdoor applications,
however, not mandatory for indoor applications.
2.3.2. Accessories
For the accessories available for the Remote Unit, e.g. overcoat housing, connecting
box or iso-trafo kit, a separate manual is available.

3. COMMISSIONING
3.1. MECHANICAL INSTALLATION
3.1.1. General
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
1. Do not install the unit in a way or at a place where the specifications
outlined in the Environmental and Safety Specifications leaflet of the
supplier are not met.
2. It is recommended only to use the mounting hardware delivered by the
supplier. If different mounting hardware is used, the specifications for
stationary use of the Remote Unit must not be exceeded.
Note: Exceeding the specified load limits may cause the loss of warranty!
3. The unit is considerably heavy. Make sure that a suitable mounting surface
is used. Ensure there is adequate manpower to handle the weight of the
system.
4. Due to power dissipation, the Remote Unit may reach a very high
temperature. Ensure sufficient airflow for ventilation as specified in the
individual mounting procedures.
5. When connecting and mounting the cables (RF, optical, mains, ...) ensure
no water can penetrate into the unit through these cables.
6. Also observe all additional rules or restrictions regarding mounting that
depend on the type of Remote Unit. For details refer to chapter 7.2.2
Mechanical Specification. Install the unit vertically with the fan unit at the
top. A maximum tilt angle of 25° from a vertical position must be kept, as in
the following illustrations:

7. A spacing of 40 mm (1.58 inch) around the unit is required.
8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two
lid openings (one for the air inlet and the other for the air outlet) have to be
provided. Do not block these air inlets and outlets when mounting the
Remote Unit. The size of each opening must equal at least 12 x 12 cm (144
cm2). Make sure, too, there is no thermal short circuit between the air inlet
and air outlet.
3.1.2. Wall-Mounting Procedure
Check the suitability of the wall-mounting kit and the wall.
Mark the position of the drilling
holes (for measurements refer to
figure 3-1 Wall mounting). Drill
four holes at the marked positions
and insert dowels *.
Use a cap nut or lock nut to screw
the four dowel screws into the
dowels and put the distance tubes
over the screws.
Hang the mounting brackets of the
Remote Unit into the screws, and
fasten them immediately using the
washers and nuts.
Ensure that there is free access to
the electrical connections as well
as to the cabinet. The approved
bending radius of the connected
cables must not be exceeded.

* The dowels are not part of the delivery since the suitable type depends on the on-site conditions
(material of wall). Therefore, use dowels that are appropriate for the mounting surface.
Page 16 MF0143A8A.doc

3.1.3. Pole-Mounting Procedure
Standard mounting hardware cannot be used to mount the Remote Unit to a pole, a
column or other similar structures. Additional hardware must be used for this type of
installation. Such a pole-mounting kit could include two threaded rods M8, two
U-beams and mounting material like bolts and nuts.
figure 3-2 Pole-mounting kit
Use the screw bands to fasten the two U-beams to the pole as illustrated in figure
3-3 Pole mounting.
Note: When fastening the U-beams make sure that they are installed
congruently and not at an angle to each other. To determine the
distance between the beams refer to 3.1.2 Wall-Mounting Procedure
for measurements.
Hang the mounting brackets of the Remote Unit into the threaded bolts of the
U-beam, and fasten them immediately using the washers and nuts.
Ensure that there is free access to the electrical connections as well as to the
cabinet. The approved bending radius of the connected cables must not be
exceeded.

3.1.4. Mounting of Fan Protection
Since the fan protection is required for the outdoor usage of a stand-alone Remote
Unit, the mounting of this optional equipment is also described in this manual.
To install the protective cover of the fan protection kit, first unscrew the four
screws with the respective lock washers from the cover of the air inlet of the
Remote Unit, and instead, screw in the four spacing bolts M4.0x30 with the four
lock washers M4.0 DIN125 that are part of the fan protection kit.
Place the protective cover into the right position by fitting its four bore holes over
the spacing bolts and fasten it using the original lock washers and screws of the
Remote Unit. (These lock washers and screws are also part of the fan protection
kit and can be used as spare parts in case of loss.)

3.2. ELECTRICAL INSTALLATION
3.2.1. General
Read the health and safety warnings in chapter 1.2.
1. This unit contains dangerous voltages. Loss of life, severe personal injury or
property damage can be the result if the instructions contained in this manual are
not followed.
2. Ground the unit before connecting power supply. A grounding bolt is provided on
the cabinet to connect the ground-bonding cable.
3. Although the Remote Unit is internally protected against over-voltage, it is
strongly recommended to earth the antenna cables close to the antenna
connectors of the Remote Unit for protection against atmospheric discharge. In
areas with strong lightning it is highly recommended to insert additional lightning
protection.
4. If the mains connector of the Remote Unit is not easily accessible, a disconnect
device in the mains circuit must be provided within easy reach.
5. Before connecting or disconnecting the mains connector at the Remote Unit,
ensure that mains supply is disconnected.
6. Make sure that an appropriate circuit breaker and an over-current limiting device
are connected between mains and Remote Unit.
7. A connection of mains supply to a power socket requires the power socket to be
nearby the Remote Unit.
8. Incorrectly wired connections can destroy electrical and electronic components.
9. To avoid corrosion at the connectors caused by electrochemical processes, the
material of the cable connectors must not cause a higher potential difference than
0.6 V (see electrochemical contact series).
10.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.
11.Use a voltage limiting device for unstabilized electric networks that frequently
generate spikes.
