1 INTRODUCTION

1.1 SC5800 Description

The SC5800 is a 5.8 GHz digital radio system that provides short to medium range,
point-to-point digital communication with high data security at rates of E1, 2E1 or
4E1. Alternatively, the radio can be software configured to convey T1, 2T1 or 4T1.
The radio can also be configured to bridge or route IP via a 10BaseT Ethernet port.
The data rates scale depending on the number of enabled E1/T1 tributaries and
whether the data is being bridged or routed. The product makes use of spread
spectrum technology and may be operated license-free in the 5.8 GHz ISM band. It
is ideal for applications such as:

• Telecommunications companies, cellular operators and private carriers.

• Cellular/PCS base station interconnects.

• Internet distribution.

• Video surveillance data distribution.

• Rural communications.

The SC5800 consists of two main parts:

• An Outdoor Unit operating in the 5.8 GHz ISM frequency band.

• An Indoor Unit, available with a Telecommunications (1, 2 or 4E1 or 1, 2 or

4T1) interface and a Data interface (10BaseT Ethernet).

Interconnection between the Outdoor Unit and Indoor Unit is achieved using a low­cost UV -protected STP (Screened Twisted Pair: 4 pairs) data cable and a UV­protected 2-core power cable. The SC5800 series product uses a split Indoor Unit
and Outdoor Unit configuration for lowest loss between the antenna and the
transceiver, thereby ensuring optimal long -range performance.

SC5800 Outdoor Unit uses a Type-N RF (female) output connector for connection to
any 5.8 GHz antenna for applications where long range is required.

2 TECHNICAL DESCRIPTION

2.1 System Overview

A SC5800 digital radio link (DRL) consists of a pair of SC5800 radio stations.

SC5800 ODU

SC5800 IDU

SC5800 ODU

SC5800 IDU

The SC5800 radio station consists of two main parts:

• An Outdoor Unit operating in the 5.8 GHz ISM frequency band. The Outdoor
Unit provides the radio transceiver functionality by accepting radio link data from
the Indoor Unit and converting it to the 5.8 GHz ISM frequency band using
spread spectrum modulation. The received signal is de-spread and transmitted
to the Indoor Unit in a digital format.

• An Indoor unit, available with 1, 2 or 4 E1 and 1, 2 or 4 T1 data interfaces
(choice of E1 or T1 is software selectable). The Indoor Unit combines nE1 or
nT1 data with Wayside Service Channel serial data and link IP data to be
transmitted across the radio link. The Indoor Unit also provides power to the
Outdoor Unit.

Interconnection between Outdoor Unit and Indoor Unit is achieved using low cost
data and power cables.

2.2 Outdoor Unit

The SC5800 Outdoor Unit makes use of Spread Spectrum modulation technology for
license-free operation in the 5.8 GHz ISM band.

User Data

User Data

For SC5800 operation, the 5.8 GHz ISM band is divided into upper and lower
frequency sub-bands. An SC5800 ‘High Band’ Outdoor Unit transmits in the higher
frequency sub-band and receives in the lower frequency sub-band, while a ‘Low
Band’ Outdoor Unit transmits in the lower sub-band and receives in the higher sub­band. An SC5800 radio link will use a ‘Low Band’ Outdoor Unit on one end of the
link to communicate with a ‘High Band’ Outdoor Unit on the other end.

The SC5800 Outdoor Unit uses a Type -N RF output connector for connection to any

5.8 GHz antenna for applications where long range is required.

SPEEDCOM SC5800 User Manual

2.2.1 Frequency plans

The SC5800 Outdoor Units operate in the 5.725 GHz to 5.850 GHz ISM frequency
band. The SC5800 has predefined frequency channel plans (termed A, B, C and D).

2.2.1.1 Frequency Channel Plan A, B and C

Transmit-to-receive channel spacing for frequency channel plans A, B and C is 69
MHz. The channel spacing is based on the bandwidth occupied by the spread
spectrum signal (approximately 17 MHz) and is used to optimize link performance.
In the case of plan A, plan B and C, note that both Outdoor Units of a link must be
set up to the same frequency channel plan (i.e., A, B or C).

Frequency plan D allows independent control of transmit and receive frequencies.
This enables a very flexible frequency plan and can be used to overcome interference
in the 5.8 GHz ISM band.

The frequencies that can be used in the lower or upper sub-bands can be selected in
1 MHz increments. Performance degradation can be expected when operating
using channel plan D mode and the chosen frequencies are close to the sub-band
edges, such as a choice of one of the high frequencies in the lower sub -band and
one of the lower frequencies in the upper sub-band.

The allocation of Channel plan D frequencies is shown in Table 2.

3 PLANNING

This chapter is aimed at management and planning staff to enable them to assess
the requirements for installing an SC5800 digital radio link.

3. 1 System Type Selection

! The SC5800 system uses an Outdoor Unit with a type-N RF output for

connection to a range of antennas.

! Antenna polarization can used to co-locate multiple SC5800 systems.
! Antenna polarization can be used to overcome interference.

3.1.1 Antenna Selection (SC5800)

The antenna type must be selected before the SC5800 system is to be insta lled.
The chosen antenna must enable the system to operate with sufficient link fade
margin without excessive cost and allow the user’s ‘link availability requirements’ to
be met.

The main consideration when selecting an antenna is antenna gain measured in dBi.
A path loss analysis is highly recommended to determine the antenna gain needed
for adequate fade margin. The table below shows antenna selection guidelines for
some configurations. The distances are calculated for a 20 dB link fade margin.

3.2 Site Evaluation

When planning a site for a digital radio link, it is of the utmost importance that you
take the operational environment of the proposed site into account.

The combined effect of atmospheric environmental factors such as rain and lightning,
atmospheric attenuation, signal path obstruction, propagation fading, air temperature
gradients, ice build-up, wind and solar radiation can contribute towards reducing the
level of performance of the system. In the higher frequency bands, rainfall is the
main attenuation mechanism that limits error performan ce. Ice and snow will have a
similar effect. Severely cold and excessively warm climatic conditions outside the
scope of the operating temperature range can affect the function of the system,
especially the outdoor equipment (see Section 8.1, Environmental Characteristics,
page 59 of this manual).

Also, if masts are not sufficiently rigid, very strong winds can affect the antenna
beam alignment and outdoor equipment reliability due to wind force build-up and/or
vibration of the mast-mounted equipment.

3.3 Multipath Effects

The SC5800 digital radio operates at frequencies close to 5.8 GHz and can be
influenced by the effects of multipath propagation. Understanding these effects will
help when installing an SC5800 digital radio li nk and maximize the reliability of the
link.

Multipath fading occurs when the receiving antenna receives not only the direct
signal from the transmitting antenna but also a signal from the transmitting antenna
that has reflected off the ground or nearby obstacles. The reflected signal takes a
longer path to reach the receiver and acts as interference since it is not in-phase
with the direct path signal. The amplitude of the interference can be almost equal to
that of the direct path signal, thus degrading the performance of the link .

Multipath propagation is dependent on transmit frequency and the specific geometry
of the link such as antenna heights, distance between the antennas and the local
terrain. To counteract multipath propagation, the installer can change the frequency
at which the link operates or adjust the height of one or both of the antennas.

3.4 Interference Considerations

The ISM frequency bands are used by devices that can cause interference to the
SC5800 radio system. Interference can be avoided by careful planning of the
system installation. The available methods for providing isolation from interfering
radiators are the following:

• Frequency diversity

• Antenna polarization

It is recommended to scan the proposed installation areas (using a spectrum
analyzer) to establish the presence of interference. The frequency spectrum should
be scanned over a sufficient time period to ensure that periodic transmissions are
recorded.

Interferers will cause problems if their amplitudes are not more than 20 dB below the
intended receive power level. A link path loss calculation should be performed to
determine the expected receive power level.

The procedure for selecting the optimum antenna polarization and system frequency
plan is the following:

• Perform a spectral analysis at each site in the link direction using a high gain
antenna.

• Repeat the spectral analysis for vertical and horizontal polarization.

• Select the polarization with the lowest interfering levels as the system

antenna polarization.

• Consult the SC5800 frequency channel plan as shown in Section 2.2.1,
Frequency Plans, page 12. Then, select the frequency plan that would operate
in an interference-free band. Give preference to channel plans A, B and C as
these are optimized for best receiver sensitivity.

• Install the ‘High Band’ and ‘Low Band’ Outdoor Units at the sites where they
would experience the lowest interference in their respective receive bands.

3.5 Micro- cell Backhaul Applications of SC5800 Digital
Radios

In applications where more than one independent and separate links, need to radiate from a
central site, a number of parameters can be taken advantage of, to provide isolation and minimize
interference between these links:

• Frequency multiplexing

• Antenna polarization

• Choice of High Antenna Gain

It is important to note that these methods only provide isolation between two radio systems, and
that power levels in the separate systems should be balanced to ensure correct operation.

3.5.1 Setting the Transmitted Power Levels

To minimize interference, received power levels should be balanced between separate radio links.
This means that transmit power levels should be set to provide similar levels of received power, as
indicated by the RSSI values of the adjacent receivers at the central site.

3.5.2 Frequency Multiplexing

The SC5800 offers four frequency channel plans. A radio link requires two channels (one for
transmit and one to receive) to provide full-duplex operation. Each radio has a high and a low sub­band, one that it uses for transmission and another for reception. Terminology definition: the
‘High-band Outdoor Unit’ of a system transmits on the higher of the two sub-bands. The ‘Low­band Outdoor Unit’ of a system transmits on the lower of the two sub-bands. A system (link)
always has one High Band and one Low Band Outdoor Unit. It is important to note that unwanted
transmitted signals in adjacent frequency bands can affect other receivers operating in an
adjacent band if insufficient antenna isolation is provided. A solution is to group high-band or low­band Outdoor Units at the central site, rather than group high and low-band Outdoor Units
together.

3.5.3 Antenna Isolation

Separate links at a central site will have sufficient isol ation when radio systems operate outside
the radiation beamwidth or side lobes of the system antenna. The achievable isolation can be
established by examining the measured radiation patterns of the system antennas. Directional
isolation can be used if the antenna radiation is 15 dB or lower relative to the adjacent main
beam. Antennas with high directionality will allow reduced angular separation of adjacent
systems. Antenna cross-polarization isolation can be used for adjacent radio links, radiating in
the same direction. Typical isolation of 30 dB can be achieved using high quality antennas.

5 ANTENNA ALIGNMENT AN D SOFTWARE SETUP

This chapter describes the procedure for software setup and antenna alignment. The
setup is done with a PC running the supplied NMS software. For more information,
see Section 6, NMS Software, page 39.

5.1 Installation Equipment Required

The following tools and instruments are required for software setup and aligning the
antenna:

• RSSI test cable

• Voltmeter

• Spanner, also called a Wrench, (see appropriate details in installation chapter

depending on the antenna being used)

• PC with NMS software and supplied serial data cable.

• Binoculars (optional) used for locating the far end site. This will assist in the

antenna alignment operation.

• GPS or Standard Compass (optional) used for locating the far end site. This
will assist in the antenna alignment operation.

• Bit Error Rate Tester and connecting leads.

5.2 Information Required

You should know:

• Proposed frequency channel plan for each station.

• Expected receive level based on the chosen system configuration and a

pathloss analysis.

5.3 Antenna Alignment

5.3.1 Introduction

The SC5800 should be installed on both sites before alignment st arts. Perform the
following steps at both stations:

1. Switch the Indoor Unit power ON.

2. Install and run the SC5800 NMS Software application.

3. Configure the radio channel plan as required.

4. Set the transmitted power to maximum.

5. Perform a RF loopback test at each site before starting the alignment
procedure.

33

SPEEDCOM SC5800 User Manual

5.3.2 Alignment Procedure

1. Locate the far site and point the antenna to the antenna at the far site, as
accurately as possible using binoculars or a compass.

2. Connect the multimeter to the RSSI connector on the Outdoor Unit using the
supplied RSSI test cable and set the multimeter to measure volts.

3. Check the RSSI level and refer to the figure below for received power level.

4. Align the antenna until the maximum RSSI is attained.

5. Secure the antenna.

6. Measure the RSSI level and record the value (see Section 5 .7, SC5800Test
Record, page 37).

7. Compare with the value with that calculated for the link (i.e., using the
pathloss calculation done when planning the link).

Figure 5. Typical Version 2 OU RSSI Voltage as a function of RF input power
level

-80dBm Average 0.436 ± 0.029 V: MIB RSSI 95 ± 1 dBm (see comment below)

-30 dBm Average 1.333 ± 0.047 V: MIB RSSI 54 ± 2 dBm (see comment below)

The MIB lists a dBm value representative of the received signal level. The value
detected is representative of the level that would be measured should a CW signal
be input at the Outdoor Unit's Diplexer RF Port - a Spread Spectrum signal will
appear to be 20 dB lower. The NMS makes an adjustment for this by using a 20 dB
offset (addition to the Indoor Unit MIB-indicated value).

The front panel RF Link LED, the Received Signal Strength Indicators (RSSI : on
NMS, via SNMP or as an Electrical signal on the Outdoor Unit), Carrier-detect
(NMS, SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with
link installation and alignment.

The front panel RF Link LED, the Received Signal Strength Indicators (RSSI: on
NMS, via SNMP or as an Electrical signal on the Outdoor Unit), Carrier -detect
(NMS, SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with
link installation and alignment.

5.3.3 Set Transmitted Power Level

It is good practice to match received power levels by adjusting transmitted powers if
co-located systems are being installed. This is important to avoid interference
between co-located systems. An attenuator can be fitted between the Outdoor Unit
and the antenna if the power level cannot be sufficiently reduced. The dBm output at
the OU N-type connector (socket) levels are set via the NMS or using a SNMP
Management application.

34

SPEEDCOM SC5800 User Manual

5.4 Software Setup

Refer to Section 6, NMS Software, page 39, for setting up the following:

• Payload interface.

• Service Channel (Wayside) serial port.

• Auxiliary in/out port.

• General link parameters.

5.5 Functional Test

After completing the physical installation of the Indoor Units, antennas, Outdoor
Units and the interconnection cables, you need to commission the system. This
procedure describes how to set up the minimum requirements for successful
SC5800 system operation.

5.5.1 Link Bit Error Rate Performance Test

To start: when the link is setup correctly, the RF Link LEDs on both IUs on both
sides of the RF link should be GREEN.

When the link has been setup and is running error-free:

1. Clear the Indoor Unit Log using Reset Button Position ‘2’

2. Clear the Indoor Unit Errors using Reset Button Position ‘1’

Perform a link bit error rate performance test as follows:

• Connect a bit error rate tester to the payload interface of the link.

• Run data over the link for a period of 24 hours.

• Record the BER.

• Record the LED statuses.

Check the Indoor Unit Packet Error Results via the NMS or via SNMP access to the
In door Unit MIB – for the NMS, right-click on the antennas in the NMS for either side
of the link and select the “Diagnostic/Error Monitor” option. Record the results by
saving the data to a file. For SNMP access, use a MIB Browser and check the
mdrmteRFLi nkPerf and mdrmteG826 Performance groups.

Record all results on a test record. See Section 5.7, SC5800 Test Record, page 37
for an example.

6 NMS SOFTWARE

6.1 Introduction to the Network Management System

The purpose of the Network Management System, hereafter called the NMS, is to
allow you to configure, manage or interrogate the following primary functional
elements of a Digital Radio Link (Local or Remote Stations within the link):

• Indoor Unit

• Ou td oor Unit

The NMS is a PC-based software package that provides you with a graphical
interface that is used to perform on-site element management of a Microwave Digital
Radio (SC5800) System. It allows you to configure, manage and interrogate the
SC5800 System by selecting various menus and options.

It provides extensive management functions on site and, via the microwave radio link,
can be used to access the remote SC5800 station.

The hardware as well as the software constituting the NMS is collectively called the
NMS Terminal.

The NMS Terminal is the principal system support equipment associated with the
SC5800 System for system installation and commissioning.

It connects to a designated NMS Terminal port (labeled Element Manager) on the
front panel of the Indoor Unit of a SC5800 Station installation, by means of a serial
data interface (this cable is supplied in the IU box).

The NMS communicates with SNMP agent software that is contained in each
SC5800 Indoor Unit. The NMS communic ates with the agent’s software: the software
enables a unit to interpret MIB (Management Information Base) commands via SNMP
(Simple Network Management Protocol).

The Operational RF parameters were programmed into the Outdoor Unit by

the local and remote Indoor Units. Communication between the two Indoor
Units has not reactivated within 5 seconds. To recover communication the
Indoor Unit has selected the ‘Default’ RF parameters and programmed the
Outdoor Unit with them.

6.7.2 Packet Error Rate Thresholds

Packet error rate (PER) is calculated as the ratio of the number of uncorrectable
blocks over the number of blocks transmitted per second. Three PER thresholds
are provided for each monitored link, these are:

• Minor PER Threshold – this threshold defaults to 0.0002 and triggers an alarm
if the calculated PER exceeds this value.

• Major PER Threshold – this threshold defaults to 0.02 and triggers an alarm if
the calculated PER exceeds this value.

• Fault PER Threshold – this threshold defaults to 2.0 and triggers an alarm if the
calculated PER exceeds this value.

54

SPEEDCOM SC5800 User Manual

6.7.2.1 G.826 Thresholds

Three G.826 thresholds are provided for each monitored link. Each of these ratios is
calculated once every second and will trigger a fault condition if the ratios exceed the
programmed thresholds that are:

• Errored Second Ratio Threshold – this threshold which defaults to 4 X 10 -2
triggers an alarm if the calculated ESR exceeds this value over the measurement
period (Report Time).

• Severely Errored Second Ratio Threshold – this threshold which defaults to 2
X 10-3 triggers an alarm if the calculated SESR exceeds this value over the
measurement period (Report Time).

• Background Block Error – this threshold which defaults to 6.25 X 10 - 2 triggers
an alarm if the calculated BBER exceeds this value over the measurement period
(Report Time).

6.7.2.2 Link Availability

A period of unavailable time begins at the onset of ten consecutive SES events.
These ten seconds are considered to be part of unavailable time. A new period of
available time begins at the onset of ten consecutive non-SES events. These ten
seconds are considered to be part of available time. The figure below illustrates this
definition.

6.7.3 RF Link Error Monitor

The Link Error Monitor screen provides the user with detailed Packet Error Rate
(PER), G.826 and link availability monitoring for the RF link. There is a status field,
Total Seconds, which applies to the link. Total Seconds is the total number of
seconds since the counts were last cleared. It is used to determine available and
unavailable seconds on a link.

10 APPENDIX B: MANAGEMENT OF THE SC5800

All management of the SC5800 product is implemented using SNMP (Simple Network
Management Protocol), an open standard. The SC5800 product can be managed by:

1. Standard SNMP managers such as HP OpenView or SNMPc (i.e., there is Open Network
Management compatibility).

2. For rapid product installation, the NMS GUI Application (hereafter referred to as the NMS­GA) provides extensive management functions on site and, via the microwave radio link,
can be used to access the SC5800 station on the opposite side of the link. The SC5800
NMS -GA is a software application that runs on a PC workstation such as a laptop or
notebook computer that is connected to an SC5800 Indoor Unit (IU) serial port (DB9 DTE)
or an Ethernet connection (10BaseT DTE) (both accessed via the IU front -panel).

10.1 SNMP and the SC5800

Use of SNMP within the product allows remote: configuration, monitoring of performance,
notification of alarms and firmware upgrades via an IP-network. Within an IP network supporting
routing of IP data, the radios can be supported from any remote location. The product can be
accessed via the Internet if the necessary gateways are provided. A GSM/PCS modem dial-up
capability provides another remote management option.

The SPEEDCOM (SC) Indoor Units have built-in SNMP agents and an extensive MIB
(Management Information Base). The SC5800 product uses SNMP V1 (RFC1155, 1157). The
user has access to an Enterprise MIB (obtainable though customer services) and MIB II (RFC

1213).

Access to the MIB via the IU SNMP agent is via Ethernet (10BaseT interface on the product's
front panel) or PPP (RFC 1661) via the product's serial channel Element Manager port. The use
of SNMP provides flexibility for operators with central equipment monitoring. It provides
management access to radio configuration (all data interfaces), interface status and statistics,
fault and maintenance information.

SNMP security (if enabled) is ensured by using a login and password to give th e user
administrator or basic user rights (a standard user rights option limits the ability to SET MIB
variables).

The product has threshold-based alarm generation (there is an extensive SNMP trap list with a
trap filter that is adjustable via SNMP). Network access (wired or wireless (i.e., GSM/PCS
Modem) allows over-the-air remote firmware uploading (FTP) with a load verification (and reversion)
capability.

81

SPEEDCOM SC5800 User

Manual

There are three principle requirements to use SNMP with the SC5800 Radio Stations.

1. A Management Station that runs a SNMP Management Software package that is
installed on a networked or stand-alone PC that can be connected to an Indoor Unit either
using a serial connection or an Ethernet connection. From the Management station, the
agents within the SC5800 Indoor Units can be configured or polled for information.

2. Agent: The agent accepts SNMP GET, SET or GET-NEXT commands from the
Management Application software and collects or adjusts information from the Indoor
Unit's MIB.

3. Management Information Base (MIB): the MIB is a database that is accessed based on
the OID (object ID) the SNMP Manager has chosen. The SPEEDCOM (SC) Indoor Unit
used an Enterprise MIB and a standard MIB (MIB II) to store or allow access to
information relevant to the SPEEDCOM (SC) Link.
