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-M8P S (I NTELLIGENT OPTICAL NETWORK; MMR)

The Andrew ION-M8P 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-M8P 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-M8P 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.

13 of 42

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
 Redundancy configuration option

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 overcurrent 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. For unstabilized electric networks which frequently generate spikes, it is advised
to use a voltage limiting device.

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.

19 of 42

 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.

3.3. CONNECTION OF THE ANTENNA CABLES

The Main Unit has N connectors. For its location, please refer to chapter 3.2.2
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.

Use an appropriate torque wrench for the coupling torque of N-type
connectors (2 N-m / 20 in lb), with 13/16 inch 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.

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.

3.4. CONNECTION OF THE RF CABLES MAIN UNIT TO COMBINING UNIT

To connect RF cables to Combining Unit, connect corresponding ports according to
frequency as labelled. For orientation of the location of connectors please refer to the

20 of 42

3.5. OPTICAL-FIBRE-CABLE CONNECTION - RULES

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-M8P 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:

21 of 42

 Remove fibre-optic protective caps.
 Do not bend the fibre-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 fibre-optic cable that will be inserted in the optical connectors on the donor
interface box.

 Blow out the laser receptacle with clean and dry compressed air to remove

any particulate matter.

 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.

 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.

3.5.1. Protective Plug

Connection:
A protective plug is provided for the connection of the fibre-optic cables.

figure 3-7 Protective-plug assembly

 Note: Only high-quality connectors must be used for this type of plug.

Qualified brands are Diamond or Huber & Suhner.

22 of 42

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.

4. ALARMS

4.1. 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.

4.2. 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.

4.3. ALARM STATUS

For details refer to the corresponding software documentation of the master unit.

4.4. STAT US LED ALARMS

For local supervision, a status LED on the connector flange of the remote unit gives
an indication of possible reasons for alarms. The position of the status LED is
illustrated in chapter 3.2.2 Connections. This table shows possible on-site measures
that could be checked before referring to the master unit alarm list.

4.5. RELAY AL ARM CONNECTING BOARD

4.5.1. External-Alarm Inputs and Outputs

There are four alarm inputs and four alarm outputs. The alarm outputs are potential­free 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 manu facturer / 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 4.5.2 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.
