2 Introduction
Page 15
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/8P S (INTELLIGENT OPTICAL NETWORK; MMR)
The Andrew ION-M7P/8P S is a multi-operator remote unit with various extension
units. It is used in conjunction with a master unit in the ION optical distribution
system. This system transports the entire 700 MHz public safety and 800 MHz LMR
frequency bands simultaneously, providing a cost-efficient solution for distributing
capacity from one or more base stations.
The ION-M7P/8P S transports signals on the RF layer in a very inexpensive manner.
This means 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 is a cost-effective 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 at poles or along
side structures in such a way that it has a minimum visual impact.
The ION-M7P/8P S performance is available both in single or multi-band
configuration supporting 700 MHz, and 800 MHz in parallel. It has been specifically
tested and optimized for TDMA, CDMA2000, and WCDMA. Furthermore it is
provisioned for future improvements to modulations (e.g. HSPA, EV-DO and OFDM)
and frequency bands. In addition it is backwards compatible to legacy standards
such as Analog.
User’s Manual for
ION-M7P/8P S
Page 16 MF0132APA.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 is a
comprehensive management platform with SNMP protocol and X.733 standard
implemented. Should a sophisticated interface not be required, the master unit can
be directly connected to the alarm interface of a base station via relay alarming.
Features:
Multi-band, multi-operator support
Reduced visual impact form factor
High, efficient power amplifier
Single fiber for multiple bands and multiple remotes
Comprehensive operations and management system for configuration and
alarming
OMC with SNMP according to X.733 standard
Easy installation and commissioning

) 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 interrupted 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.
4.3. CONNECTION OF THE ANTENNA CABLES
The Main Unit has N connectors. For its location, please refer to chapter 4.2.2
Connections. However, the Combining Unit has 7/16 antenna connectors (described
in separate manual). 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.

Optical signals are transmitted by use of optical fibres. When connecting these fibres
observe the following instructions.
) Note: Care should be taken when connecting and disconnecting
fibre-optic cables. Scratches and dust significantly affect system
performance and may permanently damage the connector. Always
use protective caps on fibre-optic connectors not in use.
In general, optical fibres do not need special protective measures. However,
protection against environmental influences e.g. rodents and humidity must be
considered.
The optical fibre is a single-mode fibre. Type is E9/125 µm with the following
minimum requirements.
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
The specified bending radius of the optical fibres must not be exceeded. The pigtails
for the connection between mini master and remote unit must have a sufficient
length. A protection for the feeding into units must be given. For ION-M7P/8P S, the
system attenuation of the optical fibres, 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 fibre, at the input and
output of the device which has to be measured.
Fibre-cable connectors have to be of the same type (E2000APC) as the connectors
used for the unit. The fibre-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 fibre cables, follow the procedure below to ensure optimized
performance. It is important for these procedures to be carried out with care:
User’s Manual for
ION-M7P/8P S
Page 26 MF0132APA.doc
¾ Remove fibre-optic protective caps.
¾ Do not bend the fibre-optic cable in a tight radius (< 4 cm) as this may cause
cable damage and interrupt transmission.
¾ Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of
the fibre-optic cable that will be inserted in the optical connectors on the donor
interface box.
¾ Blow out the laser receptacle with clean and dry compressed air to remove
any particulate matter.
¾ Connect the fibre-optic cables by inserting the cable end into the laser
receptacle and aligning the key (on the cable end) with the keyed slot.
¾ 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.
4.5.1. Protective Plug
Connection:
A protective plug is provided for the connection of the fibre-optic cables.
figure 4-7 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.
* 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.

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.
4.5.2. Protective-Tube Kit
As additional protection for the optical fibres, this connector type can be
supplemented by a special tube kit. To fasten the tube correctly, first unscrew the

5.5. RELAY ALARM CONNECTING BOARD
5.5.1. External-Alarm Inputs and Outputs
There are four alarm inputs and four alarm outputs. The alarm outputs are potential-
free relay contacts. They can be used to monitor alarms with an external-alarm
indicator. Each alarm output can be set individually to any alarm at the remote unit.
For details please refer to the according chapter in the software manual of the master
unit.
) 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.
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 device to be monitored must be connected so that the alarm contacts will be
closed in case of an alarm (maximum switching power of 28 Vdc, 0.5 A).
The location of the external-alarm inputs and outputs is illustrated in the following
chapter 5.5.2 Layout and Connector Description. Settings have to be done via the
ION-M Master Controller and are described in the according software documentation.
Please note that at the remote unit (RU), the alarm ground of the external-alarm
inputs is linked with the ground at the RU.

6.1. 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.
Maintenance of the ION-M7P/8P S should be performed on a FRU (Field
Replaceable Unit) basis only. Do not damage the warranty labels on the
components, as this voids the warranty.
The spare parts list contains only units that can be replaced without tuning or
soldering work.
) Note: When sending back the unit, use an appropriate packaging. 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 that the unit has been disconnected
from mains.
) Note: Before disconnecting any cables, label any unlabelled cables to
ensure correct reconnection.
To replace an FRU, use the appropriate tools. Replacement tools may be ordered
from the supplier. All screws have a right-hand thread, turn the tool clockwise for
tightening and counter-clockwise for loosening.
SMA connectors have a specified torque of 100 Ncm. Use an appropriate tool to
fasten and unfasten these connectors. Do not over-tighten the connectors or screws.
