2. INTRODUCTION
2.1. PURPOSE
Cellular telephone systems transmit signals in two directions between a 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.
The optical transmission uses WDM-systems with a wavelength of 1550 nm in the
uplink and 1310 nm in the downlink.
2.2. THE ION™-M7P/85P/17P/19P (INTELLIGENT OPTICAL NETWORK; MMR)
The ION-M7P/85P/17P/19P transports signals on the RF layer in a way that multiple
operators and multiple technologies are moved simultaneously from a cluster of base
stations to a remote location over the same fiber.
The ION optical distribution system provides a coverage solution for dense urban
areas, tunnels, subway, airports, convention centers, high-rise buildings and other
locations where physical structures increase path loss. It has been specifically
designed to reduce zoning problems and to provide homogeneous coverage. The
compact, mechanical design is specifically architected to mount inside of poles or
along side structures in such a way that it has a minimal visual impact.
The ION-M7P/85P/17P/19P is available in single or multi-band configuration
supporting 700 MHz, 850 MHz, 1700 MHz/ 2100 MHz and 1900 MHz in parallel. It
has been specifically tested and optimized for LTE, iDEN, GSM, EDGE, CDMA2000,
EV-DO, WCDMA, HSPA+, and OFDMA. Furthermore, it is provisioned for future
improvements to the modulation and frequency bands. In addition it is backwards
compatible to legacy standards such as TDMA and Analog.
Page 14 MF0143AUB.doc
The ION is easily set-up and supervised via a graphical user interface (GUI). Remote
units can be commissioned through the use of built-in test equipment. An auto-
leveling function compensates for the optical link loss making installation easy and
quick. The entire system may be monitored remotely via an Andrew OMC. This
platform uses SNMP protocol and is compliant to X.733 standard.
Should a sophisticated interface not be required, the Master Unit can be directly
connected to the alarm interface of a base station via its contact relay.

3.2. ELECTRICAL INSTALLATION
3.2.1. General
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
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 (25 N-m / 19 ft lb) of
7/16 DIN connectors with 1 ¼-inch opening to tighten the 7/16-type antenna
connectors. For example, use torque wrench of item no. 244377 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 19 MF0143AUB.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 21 MF0143AUB.doc
3.3. CONNECTION OF THE ANTENNA CABLES
The Remote Unit has 7/16-type antenna connectors. Please refer to section 3.2.2
Connections for its location. Refer to the corresponding documentation of the
connector manufacturer for mounting the cable connectors.
The bending radius of the antenna cables must remain within the given
specifications.
Consider the type of cable best suited for the antenna. Remember that a cable with
higher loss is less expensive but impairs performance.
Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft
lb) of 7/16 DIN connectors with 1 ¼-inch opening to tighten the 7/16-type
antenna connectors. For example, use torque wrench of item no. 244377
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.
Page 22 MF0143AUB.doc
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 power supply 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:
N
n.c.
PE
L
figure 3-8 AC power supply plug
For the AC power supply connection, a minimum cross section of 1.5
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 power supply
connector while power is on. Turn off mains power * before
connecting the power cord at the Remote Unit, then, engage mains
power again.
* Mains power must be interruptible with an external power supply breaker. For the power supply
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.

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.
Page 24 MF0143AUB.doc
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 fiber-optic cables.
figure 3-9 Protective-plug assembly
Note: Only high-quality connectors must be used for this type of plug.
Qualified brands are Diamond or Huber & Suhner.
Page 26 MF0143AUB.doc
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 27 MF0143AUB.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.

8. Connect the plug to the optical-fiber
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
Page 28 MF0143AUB.doc
*** 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:

Alarms
3.7. BITE AND ALARMS
The Built-In Test concept comprises the monitoring of the power supplies, the power
amplifiers and the optical interface.
All occurring alarms can be checked via software at the Master Unit.
3.8. HANDLING OF ALARMS
As soon as the software acknowledges a valid alarm, a message is transmitted to the
Master Unit.
If the reason for the alarm has been cleared or if the alarm should continue, a new
alarm message will not be repeated. If there was an interruption of at least five
seconds after acknowledgement, a new alarm message will be generated.
3.9. ALARM STATUS
For details refer to the corresponding software documentation of the Master Unit.
3.10. STATUS LED ALARMS

3.11. EXTERNAL ALARM INPUTS AND OUTPUTS
G1038Z0 G1038Z0
figure 3-11 Flange connector, 5 poles figure 3-12 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 3-12 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 the exact designation, please refer to chapter
5.3 Spare Parts.
Page 35 MF0143AUB.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 the designation of the
alarm kit see chapter 5.3 Spare Parts.

4. MAINTENANCE
4.1. 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/85P/17P/19P 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 5.2.3 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 power supply.
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.
4.2. 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 as well as the instructions in
chapter 4.1 General before starting with the replacement.
1. Switch off the Remote Unit. Make sure the power supply connector is
disconnected for the following replacement procedure. Then, proceed as
follows:
2. Remove the fan guard by unscrewing (Torx 20) the four countersunk-head screws
(two at each side) by which it is fastened:1)
Page 38 MF0143AUB.doc
3. Loosen the four fillister-head screws
M4x8 by which the fan unit is screwed
to the cabinet (circle-marked in the
figure to the right). 2)
4. Disconnect the fan-unit connector and
take out the fan unit.
5. To mount the new fan unit, re-connect
the fan unit connector and place the
fan unit back into its original position.
6. Screw the whole fan unit to the
cabinet with the four lens-head screws
M4x8. 2)
7. Finally mount the fan guard and fasten
it with the four countersunk screws. 1)

4.3. CLEANING THE HEAT SINK
To avoid a malfunctioning of the Remote Unit, the heat sink should be cleaned in
case of pollution. In order to prevent any damage, proceed as explained in the
following.
Note: Read the health and safety warnings in chapter 1.2 Health and
Safety Warnings as well as the instructions in chapter 4.1 General
before starting with the replacement procedure. Then, proceed as
follows:
1. Switch off the Remote Unit. For the following procedure ensure that power supply
connector has been disconnected before and that the fans have stopped rotating!
2. Before any cleaning action, remove the fan guard and the fan unit from the
Remote Unit as described in the previous chapter 4.2 Replacing the Fan Unit.
3. Clean the ribs of the heat sink (see figure 4-1 Fan unit and heat sink) very
carefully with a soft brush (not metallic!). Take care that the material is not
scratched or damaged!
4. If necessary, use compressed air (max. 5 bar) to blow out the heat sink from front
to rear side.
Note: NEVER blow out the fan unit with compressed air! This would
cause permanent damage to the unit.
5. In case the dirt cannot be blown out completely from the heat sink and parts of it,
still stick to the ribs, clean the parts concerned carefully from the front with the
soft brush. Take care that the material is not scratched or damaged.
6. After cleaning the heat sink, mount the fan unit and the fan guard again according
to chapter 4.2 Replacing the Fan Unit. Then, reconnect mains power and power
up the unit.
