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 low-
cost UV-protected STP (Screened Twisted Pair: 4 pairs) data cable and a UV-
protected 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.
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.
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 sub-
band. 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.

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 Channel Plan D
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
connec tion 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 installed.
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 performance. 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 link 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 interfe rence 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 recom mended 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 correc t 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 sub-
band, 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 ‘Low-
band 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 low-
band 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 isolation 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 AND 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 starts. 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 eac h site before starting the alignment
procedure.
SPEEDCOM SC5800 User Manual
34
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 leve l 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.

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
Indoor 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
mdrmteRFLinkPerf 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
• Outdoor 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 communicates with the agent’s software: the software
enables a unit to interpret MIB (Management Information Base) commands via SNMP
(Simple Network Management Protocol).

next page).
Frame Unlock RF link only. It looks at data received from the link. If the link is quality is
poor ( i.e., high PER at the RF level, ‘Frame Unlock’ is the result). AIS is
sent from the transceiver (from link direction) as long as ‘Frame Unlock’ is
true and no reliable data is available.
Packet Error Rate
Fault The PER Monitoring has been enabled and the Instantaneous PER has
exceeded the configured PER Fault Threshold for the RF link.
ESR Exceeded RF Errored Second Ratio has been exceeded due to Packet errors on the
RF link.
SESR Exceeded RF Seriously Errored Second Ratio has been exceeded due to Packet
errors on the RF link.
BBER Exceeded RF Background Block/Packet Errors Ratio has been exceeded due to
block errors on the RF link.
Default RF
Parameters
Activated
The Operational RF param eters 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.
SPEEDCOM SC5800 User Manual
55
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.

It is possible to purchase upgrades for E1/T1 Indoor Units (upgrades to 2E1/T1 or
4E1/T1). The user contacts the factory and provides the Indoor Unit Bar Code
number details. The factory then supplies a “Tributary Code”, unique to the Indoor
Unit, which is entered using the MIB (Version 2 product) or using the NMS (Version
2 product).
Note: SC5800 only comes in Version 2.

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 NMS-
GA) 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 the 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.
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.

12 APPENDIX D: SC5800 HARDWARE VERSION 2.X
DIFFERENCES, COMPATIBILITY SUMMARY
Version 1 hardware (Indoor and Outdoor Units) is incompatible with Version 2.x hardware. Note: THIS
MANUAL ADDRESS FEATURES SPECIFIC TO VERSION 2 OF THE SPEEDCOM SC5800 PLEASE
IGNORE REFERENCES TO OTHER VERSIONS.
• The Indoor Unit /Outdoor Unit Twisted Pair Data Interconnection for Version 2 hardware uses 2
twisted pair cables to convey payload and Outdoor Unit control signals.
Notes :
• Version 2.x firmware (can be uploaded into the Indoor Unit using the NMS’s Maintenance option).
• Updated RSSI and Power control functionality have been added to Version 2.x hardware and
firmware.
Version 2.x firmware has
1. FTP upload functionality (needs to be activated via the MIB)
2. IP Bridging functionality (half and full duplex – selectable via the MIB)
3. Band Plan C
4. Refer to the MIB section of this manual and look for the † symbol to see what MIB-related
functionality is in place/activated/planned for Version 2.x + firmware.
5. Functional RF Loopback built-in test feature.
Version 2.x NMS has
1. Ability to allow the user to connect to the Indoor Unit using PPP (via a serial cable interface to the
IU’s front panel Element Manager RS232 port) or via Ethernet (via the front panel RJ45 connector:
10BaseT).
2. Graphical Spectrum Analyzer display
By default, firmware provided for the Indoor Units does not provide a secure login feature (thereby limiting a
user’s ability to ‘set’ MIB variables). Suitably adapted firmware versions (dependent on hardware version)
need to be requested from the product manufacturer to allow activation of this feature.
INDOOR UNIT FIRMWARE UPGRADE NOTICE
• Version 2 hardware Indoor Units are identified as have 200+ serial numbers, Outdoor Units have
250+ serial numbers.
• If upgrading Indoor Units to use V2.02+ IU firmware, upgrade the IU firmware on BOTH sides of
the RF Link.
• Note that firmware upgrades of Version 1 Indoor Unit hardware do not require setting up of the
PCB Issue in the MIB (i.e., mdrmteIndoorUnitPCBrevision element.) Upgrade to IU firmware
Version 2+ of Version 1 hardware will NOT give improved RSSI functionality. This is only achieved
with Version 2 hardware or modified version 1 hardware.
• As a standard setting for mdrmteIndoorUnitPCBrevision, use MIB selection Issue_2. HOWEVER,
if an appropriate Indoor PCB modification (made at the factory) has been made to allow Full-
Duplex Ethernet operation, the Issue_2_Mod_A selection option in the MIB MUST be used.
