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

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.
Page 20 MF0143A8A.doc
12. The unit complies with the surge requirement according to EN 61000-4-5 (fine
protection); however, it is recommended to install an additional medium (via local
supply connection) and/or coarse protection (external surge protection),
depending on the individual application, in order to avoid damage caused by
overcurrent.
13. Observe the labels on the front panels before connecting or disconnecting any
cables.

After loosening the hex nut, connect the earth-bonding cable between the two
washers as illustrated in the figures above. Then, fasten all parts again with the hex
nut.
Page 22 MF0143A8A.doc
3.3. CONNECTION OF THE ANTENNA CABLES
The Remote Unit has 7/16-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. POWER CONNECTION
Before connecting electrical power to the units, the system must be grounded as
described in the previous chapter.
Mains power must be connected at the mains connector of the unit (see chapter
3.2.2 Connections).
The power supply plug is part of the delivery. The correct wiring of the power supply
plug is as follows:
figure 3-9 AC mains plug figure 3-10 DC mains plug
For the AC power supply connection, a minimum cross section of 1.5
mm2 is required, and for the DC power supply connection a minimum
cross section of 2.5 mm2 is required. Each wire must observe the
applicable national regulations regarding loop impedance, voltage drop,
and methods of installation. Make sure to connect the correct voltage to
the unit.
Note: Do not connect or disconnect the power cord at the mains connector
while power is on. Turn off mains power * before connecting the
power cord at the Remote Unit, then, engage mains again.
* Mains power must be interruptible 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.

3.5. 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.
System 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:
Remove fiber-optic protective caps.
Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause
cable damage and interrupt transmission.
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.
Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.
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.
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.
Cleaning 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.

3.5.1. Protective Plug
Connection:
A protective plug is provided for the connection of the fibre-optic cables.
figure 3-11 Protective-plug assembly
Note: Only high-quality connectors must be used for this type of plug.
Qualified brands are Diamond or Huber & Suhner.
For plug assembly, observe the following instruction:
1. Pass one or two contacts through the
backshell and the clamp ring.
2. Place the contact(s) on the lower insulation body by pushing the groove of the
contact into the cavity. If there is only one contact, cavity A must be used. *
3. Then, mount the upper insulation body on the lower insulation body. **
4. Bring the insulator into the plug. The narrow groove of the insulator must be fitted
into the stamp of the plug.
Page 28 MF0143A8A.doc
* To release the contact for disassembling, push the inner snap to the side and pull the contact out.
** To release upper and lower insulation bodies for disassembling, use a small screwdriver and
carefully open the snap-connections at the left and the right side of the insulator without
damaging them.
5. Fasten the insulator by screwing the
backshell tight onto it. Use a spanner
with opening 32 to screw the
backshell tight (no gap).
6. Place the appropriate seal parts (with
one groove for one contact or two
grooves for two contacts) over the
cable(s) and push them into the
backshell.

7. Bring the plastic ring over the cable(s), push it into the backshell and compress
the seals and plastic ring by screwing the clamp ring tight (no gap) using a
spanner with opening 20. ***
8. Connect the plug to the optical-fibre
connector of the Remote Unit, again
by fitting a stamp on the plug into the
groove of the connector.
9. To lock the connector, push the black
locking ring forward.****
Screw tight until gap is closed
*** For disassembling, release the clamping ring and remove the seals and the plastic ring first.
**** Locking mechanism: The system of locking the plug is based on a “push-pull” mechanism. The
locking ring has to be pushed forward to lock the connector and pulled back to free the
connection.
3.5.2. Protective-Tube Kit
As additional protection for the optical fibers, this connector type can be
supplemented by a special tube kit. To fasten the tube correctly, first unscrew the
clamp ring (if already installed) of the original plug kit.
Then, proceed according to the following instruction:

4. ALARMS
4.1. BITe AND ALARMS
The Built-In Test (BITe) concept comprises the monitoring of the power supplies, the
power amplifiers and the optical interface.
All alarms occurring can be checked via software at the Master Unit.
4.2. HANDLING OF ALARMS
A message is transmitted to the Master Unit when the software acknowledges a valid
alarm.
A new alarm message will not be repeated if the reason for the alarm is cleared or if
the alarm continues.
A new alarm message will be generated if the alarm is interrupted for at least five
seconds after acknowledgement.
4.3. ALARM STATUS
Refer to the corresponding software documentation of the Master Unit for details.
4.4. STATUS LED ALARMS

4.5. 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 is available to connect external devices to the
external alarm inputs and outputs (for ID No see section 6.3 Spare Parts).
Page 36 MF0143A8A.doc
With 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.
Subminiature circular connectors series 712 with five and seven contacts, which are
contained in the alarm kit, can be ordered directly from the Binder Connector Group,
the manufacturer, or indirectly from Andrew Solutions (for ID No of the alarm kit see
section 6.3 Spare Parts).

5. MAINTENANCE
5.1. GENERAL
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
Note: The Remote Unit does not require preventative maintenance
measures.
Note: To prevent malfunctions of the cooling system due to dirt or
pollution, it is recommended to clean the heat sink at regular
intervals. These cleaning intervals depend mainly on the location
of the Remote Unit and the corresponding degree of pollution.
Maintenance of the ION-M7P should be performed by replacing only components
that are contained in this chapter. In order to maintain warranty, take care not to
damage unintentionally the seals on the modules.
The spare parts list, consequently, contains only units which can be replaced without
tuning or soldering work.
Note: When sending back the unit, use an appropriate packaging, see
chapter 6.2.3 Environmental and Safety Specifications. We
strongly recommend using the original packaging!
Note: Defect parts should only be replaced by original parts from the
supplier. All interventions inside the housing are at one’s own risk.
Note: During maintenance ensure the Remote Unit has been
disconnected from mains.
Note: Before disconnecting any cables, label any unlabelled cables to
ensure correct connection.
For most maintenance procedures appropriate tools are required to ensure correct
handling. All these tools can be ordered from the supplier. For screwing procedures
observe that all our screws have a right-hand thread, i.e. for fastening the screws
turn the tool clockwise and for unscrewing them turn it counter-clockwise.
Due to the design of the Remote Unit the only component recommended to be
replaced is the fan unit. For replacing any other component, please contact the
supplier.
5.2. REPLACING THE FAN UNIT
Replacement of the fan unit is not required as a preventative measure. Only if an
alarm indicates a malfunctioning of a fan must the unit be exchanged.
Note: Please observe that the fan unit can only be replaced as a whole. Do
not remove the fans separately.
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings as
well as the instructions in chapter 5.1 General before starting with the replacement.
1. Switch off the Remote Unit. Make sure mains is disconnected for the
following replacement procedure. Then, proceed as follows:
2. Loosen the four tallow-drop screws
M4x8 by which the fan plate is
screwed to the cabinet. Remove the
four screws and the corresponding
washers.
3. Remove the fan unit – by putting slight
pressure on the fan plate cover – to a
position that allows access to the fan
connector and the earth-bonding
cable.
4. Unscrew the fan connector and then
disconnect the earth-bonding cable.

5.3. CLEANING THE HEAT SINK
Note: Read the health and safety warnings in chapter 1.2 Health and
Safety Warnings as well as the instructions in chapter 5.1 General
before starting with the replacement procedure. Then, proceed as
follows:
1. Switch off the Remote Unit. For the following procedure ensure that mains has
been disconnected before!
3. Use compressed air (max. 5 bar) to
blow out the heat sink from back to
front:
2. Remove the fan plate with the fan unit
from the Remote Unit as described in
chapter 5.2 Replacing the Fan Unit,
steps 1 and 2:
4. In case the dirt cannot be blown out completely and parts of it stick to the ribs of
the heat sink, clean the parts concerned carefully from the front using e.g. a
