Antenna Installation Warning
1. All antenna installation and servicing is to be performed by qualified technical personnel only. When servicing
the antenna, or working at distances closer than those listed in the tables below, ensure the transmitter has been
disabled.
Typically, the antenna connected to the transmitter is a directional (high gain) antenna, fixed-mounted on the
2.
side or top of a building, or on a tower. Depending upon the application and the gain of the antenna, the total composite power could exceed 20 to 50 watts EIRP. The antenna location should be such that only qualified technical
personnel can access it, and that under normal operating conditions no other person can touch the antenna or
approach within 4.34 meters of the antenna. This is a worst case scenario derived from maximum permissible exposure evaluation
for General Population/Uncontrolled Exposure using maximum permitted antenna gain (30 dBi) for LEDR Series

1.0INTRODUCTION
This manual is intended to help an experienced technician install, configure, and operate one of the digital radios in the MDS LEDR Series:
400S/F, 700S, 900S/F or 1400S/F. The manual begins with an overall
description of product features and is followed by the steps required to
install the radio and place it into normal operation.
After installation, we suggest keeping this guide near the radio for future
reference.
1.1Product Description
The LEDR radio (Figure 1) is a full-duplex, point-to-point digital radio
operating in one of three radio frequency bands and at several bandwidths as summarized in Table 1.
With the addition of an optional Fractional-T1 Interface card, a
LEDR 700S or 900S Series radio can be connected to industry-standard
G.703 T1 data interface equipment. See Page 115 for a complete
description of the Fractional-T1, Fractional-E1 and Full Rate E1
options.
All LEDR Series radios (with the exception of the 700S) are available
in a protected “1+1” configuration. The protected configuration consists
of two identical LEDR radios and a Protected Switch Chassis (Figure 2).
The protected configuration performs automatic switchover to a secondary radio in the event of a failure in the primary unit. See PRO-
TECTED CONFIGURATION on Page 103 for detailed information on
this mode.

3.0HARDWARE INSTALLATION AND
BASIC INTERFACE
REQUIREMENTS
3.1Introduction
Installation of the LEDR radio transceiver is not difficult, but it does
require some planning to ensure optimal efficiency and reliability. There
are two major installation objectives; first, obtain good radio communications between LEDR sites, and second, configure the data interface to
complement your data equipment.
This section provides information to assist you in successfully completing the first phase of installation. You will find tips for selecting an
appropriate site, choosing antennas and feedlines, minimizing the
chance of interference, and the basics of equipment installation. This
material should be reviewed before beginning the radio hardware equipment installation.
When the radio installation is successfully complete, you will need to
address the data interface and operational configuration of the LEDR
radio. It is likely that the radio has been configured by the factory to
meet your basic data interface requirements. Please review the factory
documentation accompanying your shipment for the radios current configuration.
What ever your situation, it is recommended you review the material in
the rest of the manual to gain insight to additional configuration options
and user functions.
3.2General Requirements
There are four main requirements for installing the radio transceiver—a
suitable installation environment, adequate and stable primary power, a
good antenna system, and the correct interface between the transceiver
and the external data equipment. Figure 6 shows a typical station
arrangement.

Site Selection
For a successful installation, careful thought must be given to selecting
proper sites for the radios and antenna systems. Suitable sites should
offer:
• An antenna location that provides an unobstructed path in the
direction of the associated station
• A source of adequate and stable primary power
• Suitable entrances for antenna, interface or other required
cabling
• Adequate clearance around the radio for ventilation
These requirements can be quickly determined in most cases. A possible
exception is the first item—verifying that an unobstructed transmission
path exists. Microwave radio signals travel primarily by line-of-sight,
and obstructions between the sending and receiving stations will affect
system performance.
If you are not familiar with the effects of terrain and other obstructions
on radio transmission, the following discussion will provide helpful
background.
Terrain and Signal Strength
A line-of-sight path between stations is highly desirable, and provides
the most reliable communications link in all cases. A line-of-sight path
can often be achieved by mounting each station antenna on a tower or
other elevated structure that raises it to a level sufficient to clear surrounding terrain and other obstructions.
8LEDR Series I/O GuideMDS 05-3627A01, Rev. D
Page 17
The requirement for a clear transmission path depends upon the distance
to be covered by the system. If the system is to cover only a limited distance, say 5 km (3.1 miles), then some obstructions in the transmission
path may be tolerable. For longer-range systems, any obstruction could
compromise the performance of the system, or block transmission
entirely.
The signal strength at the receiver must exceed the receiver sensitivity
by an amount known as the fade margin to provide reliable operation
under various conditions.
Detailed information on path planning should be reviewed before beginning an installation. Computer software is also available for this purpose
that can greatly simplify the steps involved in planning a path.
Microwave Data Systems offers path analysis (for paths in the USA) as
an engineering service. Contact the factory for additional information.
On-the-Air Test
If you’ve analyzed the proposed transmission path and feel that it is
acceptable, an on-the-air test of the equipment and path should be conducted. This not only verifies the path study results, but allows you to
see firsthand the factors involved at each installation site.
The test can be performed by installing a radio at each end of the proposed link and checking the Received Signal Strength Indication (RSSI)
value reported at the front panel LCD screen of each radio. If adequate
signal strength cannot be obtained, it may be necessary to mount the station antennas higher, use higher gain antennas, or select a different site
for one or both stations.
A Word About Interference
Interference is possible in any radio system. However, since the LEDR
radio is designed for use in a licensed system, interference is less likely
because frequency allocations are normally coordinated with consideration given to geographic location and existing operating frequencies.
The risk of interference can be further reduced through prudent system
design and configuration. Allow adequate separation between frequencies and radio systems.
C/I Curves
A carrier to interference (C/I) curve can help in frequency and space
coordination. The information in this curve can aid greatly in helping
plan geographic locations and frequency usage for radio systems. Contact the factory for additional information on carrier to interference
curves. A white paper (publication no. 05-3638A01) on the subject is
available from MDS at www.microwavedata.com. Search for the term
“LEDR” under the manuals download area to see this, and all other publications pertaining to the LEDR series.
MDS 05-3627A01, Rev. DLEDR Series I/O Guide9
Page 18
Keep the following points in mind when setting up your point-to-point
system:
1. Systems installed in lightly populated areas are least likely to
encounter interference; those in urban and suburban environments
are more likely to be affected by other devices operating in the
radio’s frequency band and adjacent services.
2. Directional antennas must be used at each end of a point-to-point
link. They confine the transmission and reception pattern to a comparatively narrow beam, which minimizes interference to and from
stations located outside the pattern. The larger the antenna, the more
focused the transmission and reception pattern and the higher the
gain.
3. If interference is suspected from another system, it may be helpful
to use antenna polarization that is opposite to the interfering system’s antennas. An additional 20 dB (or more) of attenuation to
interference can be achieved by using opposite antenna polarization.
Refer to the antenna manufacturer’s instructions for details on
changing polarization.
3.3Antenna and Feedline Selection
Antennas
The antenna system is perhaps the most crucial part of the system
design. An antenna system that uses poor quality feedline, or is improperly aligned with the companion site, will result in poor performance, or
no communication at all.
A directional antenna must be used for point-to-point systems to minimize interference both to and from nearby systems. In general, cylindrical or dish type antennas with a parabolic reflector must be used. Yagi
or corner reflector types may be acceptable in some applications. Check
government regulations for your region.
The exact style of antenna used depends on the size and layout of a
system. In most cases, a directional “dish” type of antenna is used with
the radio (Figure 7). Dish antennas maximize transmission efficiency
and restrict the radiation pattern to the desired transmission path.

MDS can furnish antennas for use with your LEDR radio. Consult your
sales representative for details.
Feedlines
For maximum performance, a good quality feedline must be used to
connect the radio transceiver to the antenna. For short-range transmission, or where very short lengths of cable are used (up to 8 Meters/26
Feet), an inexpensive coax cable such as Type RG-213 may be acceptable.
For longer cable runs, or for longer-range communication paths, we recommend using a low-loss cable suited for the frequency band of opera-
™
tion. Helical transmission lines, such as Andrew Heliax
or other
high-quality cable will provide the lowest loss and should be used in
systems where every dB counts. Whichever type of cable is used, it
should be kept as short as possible to minimize signal loss.
Remember that cable loss increases in direct proportion to the transmission frequency used. This means that a system operating at 900 MHz
will experience more cable loss than one operating at 400 MHz.

3.4Radio Mounting
The radio can be mounted either in a 19-inch equipment rack or on a
table top. It should be located in a relatively clean, dust-free environment that allows easy access to the rear panel connectors as well as front
panel controls and indicators. Air must be allowed to pass freely over the
ventilation holes and heat sink on the side panel.
The dimensions of LEDR Series radios are:
• 305 mm (12 in) deep
• 426 mm (16.75 in) wide—Excluding rack mounting brackets
• 45 mm (1.75 in) high—1RU
Maximizing RSSI
For newly installed systems, one of the first tasks is to orient the station
antenna for a maximum Received Signal Strength Indication (RSSI) as
shown on the LCD screen. See “Performance” on Page 40 for details. A
maximum RSSI ensures the antenna is properly aimed at the associated
station. Move the antenna slowly while an assistant observes the RSSI
display for a maximum reading. There may be a time delay between
moving the antenna and updating of the RSSI display. Be sure to allow
adequate time between antenna movements and observations.
Attaching the Rack Mounting Brackets
The radio is normally shipped with the rack mounting brackets uninstalled. To attach them, select the desired mounting position on the sides
of the chassis. (The brackets may be mounted in one of two locations—
flush with the front panel, or near the middle of the chassis.)
NOTE: Both short and long screws are provided with the brackets. Use
the long screws for the heatsink (left) side of the chassis and
the short screws for the right side of the chassis. Tighten the
screws securely.

Connectors
The front panel of the LEDR radio (Figure 10) has two connectors; both
of them are located on the lefthand side of the panel.
OrderwireThe RJ-11 jack with the telephone symbol above it is to connect an
orderwire handset. The orderwire is used by service personnel to communicate through the Service Channel to coordinate system activities
with personnel at another site in the network. The orderwire will not
interrupt the normal data flow through the LEDR data communication

Ethernet
The ETHERNET connector provides access to the embedded SNMP
agent and other elements of the TCP/IP network-management interface.
The connector is a standard 10Base-T connection with an RJ-45 modular connector.The LEDR Ethernet connections are provided for remote
equipment management (NMS).
Ethernet in
a Repeater
Configuration
At a repeater site with two LEDR radios, the ETHERNET connectors of
each chassis must be connected to each other through a cross-connect
cable or using standard cables to an Ethernet hub. This inter-chassis
Ethernet connection must be made in order for the Orderwire and Service Channel to function properly. (See Figure 13 on Page 21 for further
information.)
MDS 05-3627A01, Rev. DLEDR Series I/O Guide19
Page 28
Ethernet in
a Protected
Configuration
The Ethernet connections on the LEDR radio chassis in a protected configuration should not be used. The Ethernet connector of the Protected
Switch Chassis (PSC) provides a connection to the two radio units. Each
radio has a unique IP address and is individually addressable/controllable using SNMP over IP. See “PROTECTED CONFIGURATION”
on Page 103 for general information and Figure 34 on Page 128 for
ETHERNET connector pinout details.
EIA-530-A
The EIA-530-A connector is the main data input/output connector for
the subrate radio. The EIA-530 interface is a high-speed serial data connector. For detailed pin information, see “EIA-530-A Data—Rear
Panel” on Page 128.
NOTE: This connector is not operational on LEDR “F” Series (fullrate)
models.
Service Channel
The Service Channel provides a transparent ASCII “pipe” to which any
RS-232/EIA-232 device can be connected at data rates between 300 and
9600 bps. Whatever ASCII data is entered onto the network through the
Service Channel Port will be sent to the local radio and broadcast to any
other device connected to the Service Channel Port on other associated
LEDR radios in the network.
The Service Channel’s function is identical for all LEDR configurations—stand-alone, repeater, and redundant.
NOTE: Use of the orderwire will slow down data communications on
the Service Channel. It will not effect data traffic on the
primary data interface.
For detailed information on this 9-pin connector, see “Service
Channel—Rear Panel” on Page 129.

nector of the Protected Switch Chassis (PSC) provides a connection to
the two radio units. For further information on protected configurations
please see “PROTECTED CONFIGURATION” on Page 103.
RADIO B
Alarm I/O
This is a 9-pin connector that has both inputs and outputs.
Output ContactsThe ALARMS Port is outfitted with four optically-isolated relays that are
controlled by the LEDR radio’s CPU. The contacts (Pins 6, 7, 8, & 9)
are normally open and can handle a non-inductive load of ±60 Volts
Peak (AC/DC) at a maximum current of 1 Ampere. These are suitable
for the control of an external device or indicator when a radio event
occurs.
An alarm output could be used, for example, to sound a claxon when the
radio link goes down, or when the battery for the real-time clock is low.
Another example is to use the alarm outputs to drive the inputs of an
external monitoring system. (See the list of radio events for more
options.) These outputs are not suitable for data interface without the use
of an external “debouncing” circuit.
MDS 05-3627A01, Rev. DLEDR Series I/O Guide21
Page 30
Input ConnectionsIn addition, four external alarm input lines (Pins 1, 2, 3 & 4) are pro-
vided. Normally, the input is either left open or shorted to ground, to
indicate an alarm condition.
Each alarm input is diode-clamped to +3.3 Vdc or chassis ground, and
can tolerate inputs from -4 to +6 Vdc without drawing excessive current.
If left open, each input is pulled up. To indicate an alarm condition, short
the input pin to the ground provided on the alarm connector (Pin 5). The
maximum DC loop resistance is 2 KΩ. These alarm input lines can tolerate circuit “bounce” common with mechanical relays.
NOTE: The normal (unalarmed) state of the contacts (open or closed)
or input alarm state (high or low) can be selected by a software
subcommand. See “alarm” on Page 50 for details.
Alarm EventsThe events that cause alarm output signals can be configured in the radio
software. See “evmap” on Page 58 for information on programming
which events trigger an alarm.
See Figure 38 on Page 129 for Alarm I/O pinout information.
DC POW ER INPUT connector is a three-pin keyed connector used to
connect an external DC power source. A label next to the power connector indicates the nominal voltage of the radio. Table 9 lists the actual
operating voltage ranges.
The connector matches with a power plug (MDS Part No. 73-1194A22)
which contains binding posts for attaching the positive and negative
power leads. The polarity of the power connections does not matter; the
positive and negative leads may be connected to either the left or right
binding posts as shown in Figure 11 and Figure 12. The center conductor is not connected in the LEDR chassis and should be left unwired.
Table 9. Primary Power Input Options
Nominal Voltage Operating Range
24 Vdc19.2 to 28.8 Vdc
48 Vdc38.4 to 57.6 Vdc
Before connecting primary power to the radio, verify that the source
provides a voltage within the proper operating range. Improper voltages
may damage the equipment. Permissible voltage limits are shown in
Table 9.

Protected Configuration Connections
There are several connections between the LEDR radio chassis and the
Protected Switch Chassis. They include the primary data interface, RF,
Ethernet, orderwire and Service Channel. Details on cabling and other
items relating to the protected (redundant) configuration appear in PRO-
TECTED CONFIGURATION on Page 103.
3.7Bandwidths, Data Rates and Modulation Types
The hardware in the LEDR chassis is configured at the factory for a specific bandwidth. However, the modulation type and data rate can be
changed as long as the bandwidth is sufficient to support the modulation type and data rate. (If you need to change your radio’s bandwidth,
please see “INCREASE BANDWIDTH BY CHANGING TRANS-
MITTER AND RECEIVER FILTERS” on Page 120 for details.)
Use of the
modem command (Page 71) and configuration ([argument])
code automatically sets the combination of data rate, bandwidth and
modulation type if the radio is capable of supporting it
Table 10 shows the combinations of radio bandwidth, data rates and
modulation types that are available for subrate radios at the time of publication. Table 11 shows the combinations available for fullrate radios.

3.8Transmit Clock Selection (Subrate Radios Only)
For a subrate radio, transmit clock arrangement must be set by the user.
Clocking arrangements for fullrate radios is automatically handled by
the LEDR radios.
It is essential that there be only one master clock in a subrate radio network. The master clock can originate from the radio or from the Customer Premises Equipment (CPE).
LEDR radios are capable of several different clocking modes. Refer to
Figure 14 and Figure 24 for typical system clocking arrangements.

CONSOLE Port.
NOTE: When customer premises equipment (CPE) is operated in
looped clock mode, it is recommended that the radio not be set
to line clock mode. To do so may cause the transmitting
radio’s PLL to be pulled out-of-lock, especially when operating at 4E1 data rates.
The radio is commonly configured to parameters provided by the customer at the time the order was placed. Even so, there are some parameters that must be reviewed and set during installation. The following
steps summarize the initial set-up of a LEDR radio link. If this is your
first installation of a LEDR radio system, it is recommended the equipment be set up on a test bench.
4.2STEP 1—Power up the LEDR Radios
There is no primary power switch; simply connecting primary power to
the unit will start the radio operating. After a short self-test, a “default
screen” similar to the following appears on the radio’s LCD display:
NOTE: The LEDR radio is normally keyed continuously, and the radio
will transmit whenever power is applied. Ensure there is a suitable load on the antenna connector before connecting power.

4.3STEP 2—Establish Communications with the
Radio
There are four different methods available to set radio parameters and
query the radio. They are:
• Front Panel—The front panel is intended to serve as a convenient user inter-
face for local radio management. Most, but not all, parameters and functions
are accessible from the front panel. (See “Front Panel LCD Menu Descrip-
tions” on Page 32.)
• NMS(Network Management System)—The NMS is used via a terminal
connected to the front panel CONSOLE Port. It may be used to configure
and query every manageable radio parameter on a given network using the
out-of-band Service Channel. The Element Management System (EMS) may
be used on the local radio (login command) or through any remote radio in
the network using the rlogin command.
• Telnet—A standard network application protocol which provides a
NMS-type interface to configure and query most radio parameters.
• SNMP Network Management System—The SNMP agent interface is opti-
mized to fulfill the fault configuration, performance and user access requirements of the LEDR radio system. A separate manual, MDS P/N 05-3532A01
explains SNMP in more detail.
4.4STEP 3—Make Initial Login to Radio
Navigation Key
Method
When the radio is first powered up, it defaults to a read-only condition.
That is, the radio parameters may be viewed, but cannot be changed. To
enable changes to radio settings, a valid user name and password must
be entered.
When the radio is shipped from the factory, it is pre-programmed with
the following temporary login credentials:
Username:
SUPER
Password:SUPER
NOTE: User names and passwords are case sensitive. Do not use punc-
tuation mark characters. A maximum of eight characters are
allowed.
To log in from the front panel using the temporary credentials, follow
these steps:
1. Go to the Login screen and press the front panel key. The
Username screen appears with

NOTE: It is recommended that users log out when finished using the
front panel navigation keys or console terminal. This can be
done using the Logout screen on the radio, or the logout
command from a console terminal as appropriate. If there is no
key or terminal activity for 10 minutes, the radio automatically
logs out and reverts to read-only status.
4.6STEP 5—Review Essential Operating
Parameters
Review and set the following parameters to allow data throughput and
interconnection with the network. These are radio operating frequencies, data interface clocking, and data framing. Table 12 outlines these

for increased network addressing efficiency.
Example: Consider an IP address in a Class C network, such as
150.215.017.009. The Class C network means that the right-most group
of numbers (009) identifies a particular host on this network. The other
three groups of numbers (150.215.017) represent the network address.
Subnetting allows the further division of the host part of the address
(right-most group of numbers) into two or more subnets. A subnet mask
of 255.255.255.127 allows half of the host portion of the IP address to
be reused to define sub-networks.

6.4Command Detailed Descriptions
Introduction
The following commands are available through the CONSOLE port.
These commands all require the Enter or Return key be pressed after the
command.
The following conventions are used to help describe the usage of the
commands.
Square brackets
[ ] contain subcommands that may or may not be
needed as part of the desired command. If there is more than one
possible subcommand a vertical line
| separates the commands
within the square brackets. A subcommand is an optional extension of the command and changes the basic command.
Angle brackets
<> contain arguments. The arguments are values
needed to carry out the command such as a frequency value or
option.
Some commands are limited to use in certain radio models or configurations. These include subrate and fullrate. One or more of the symbols
as listed in Table 16 will identify these commands.

ais Alarm Indication Signal
FT1
E1
FE1
Usage:
ais [linelist] [-g <on|off>] [-f <on|off>]
This command enables or disables alarm signal generation [-g] and forwarding [
-f] on specified E1/T1 interface lines. When generation is
enabled, fault conditions within the link or at the line interface will cause
the appropriate AIS/RAI signaling to occur. When forwarding is
enabled, AIS/RAI signaling at the line interfaces will be detected and
passed to the other end of the link.
Command Example:
ais -f on -g on
Returns:
AIS on RAI on
NOTE: For protected configurations and full-rate radios, disable the
alarm generation through the use of the ais -g off command.
Background on AIS command:
In fractional operation, the radio extracts the required timeslots and data
at the input to a link, and reconstructs the full frame at the output end.
The
AIS -g (generation)> command, when enabled, allows the radio to
override the frame reconstruction process in order to generate a proper
all-ones alarm signal. For example, modem loss of synchronization will
cause all-ones to be transmitted from the active G.703 ports. When
AIS -g
is disabled, the output will consist of a framed signal with all-ones in the
active timeslots. In Fractional operation, AIS generation also creates a
yellow alarm/RAI back to the defective source when a problem is found
at the input. In FE1 mode, when
AIS -g is enabled, loss of Multi-Framing
Alignment Sequence (MFAS) at the line receiver will generate a
Multi-frame Yellow Alarm (MYEL) or Multi-frame Remote Alarm
Indication (MRAI) at the line transmitter.
AIS <-f (forwarding)> is the act of detecting a condition at the input and
causing an appropriate response at the other end. For example, with forwarding enabled, an all-ones signal applied at one end causes all-ones to
be output at the other. A Remote Alarm Indication (RAI) applied will
likewise appear at the opposite end. Disabling the forwarding function
limits the presentation of alarm signaling to the active timeslots at the
remote end. It is recommended that the
ais -f on or ais --g on command be
used for Fractional operation, to enable alarm generation and forwarding.
In full-rate modes, the radio will always output AIS when the unit is
unlocked—received radio signal is lost. When the modem is locked, and
the input is removed from one end, you will get all-zeros at the other end
unless AIS generation is enabled. Yellow alarms/RAI are not generated
MDS 05-3627A01, Rev. DLEDR Series I/O Guide49
Page 58
in the full-rate LEDR radio models; however AIS and RAI forwarding
are available. It may be desirable to have alarms generated (
full rate models, depending on the user's requirements as outlined in the
next paragraph.
Since the generation and forwarding operations require use of the Service Channel, the AIS/RAI response times are on the order of a few seconds. Generation and forwarding can be very helpful in correcting
problems with the network when they arise. However, in systems where
the response time is critical, these modes should be disabled: In fractional mode, enter
alarmAlarm I/O
ais -g on) in
ais -f off -g off. In full-rate mode, enter ais -g off.
Usage:
alarm [in|out] [1-4|all] [subcommand] [arguments]
This command is used to control the four (4) external alarm contacts and
display the state of the four (4) external alarm inputs.
Outputs (Relays)—Alarm outputs may be directly driven to a
state, or be mapped to, internal events via the
evmap command
(Page 58). When mapped to events, the active level may reprogrammed to be either active-open or active-closed. Active means
that an event is mapped to an e xternal alarm output that is currently
active. (See “Alarm I/O” on Page 21 for electrical parameters and
typical examples of alarm usage.)
Inputs—Alarm inputs are used to generate events in the event log
and also generate SNMP traps if so programmed by the
command. They may be directly read via the
alarm command, as
events filter
well. They may also have their active level set to be either active
high or low. (
alarm active high; alarm active low)
Naming—Finally, both inputs and outputs may be named by users
to allow for easy identification. For e xample, “Fire Alarm” could be
used as the name for Alarm Input 1. Traps are sent with this name
so that users may more easily identify the source of the alarm.
Subcommands:
active [open|closed]—Set alarm input/outputs active state.
set [open|closed] —Latch alarm outputs to one state to ignore events
which are assigned to them.
name [name_string]—Create a user defined “name” for each alarm. No
spaces, 16 characters maximum; not compatible with “
all”.

alertAlert another LEDR Radio in the Network
Usage: alert <3 digit unit ID>|all
This command is used to sound the alert buzzer on another radio. This
function allows you to signal a radio and alert someone that the Orderwire handset should be picked up.
The three-digit number following the command indicates the unit ID of
the radio that will be signaled. Radios available for signaling can be
determined by issuing the
network command. See “USING ORDER-
WIRE” on Page 99 for more information.

This command displays the contents of the radio’s ARP table, which is
a listing of IP addresses of which the radio is aware. It can also be configured to “spoof,” or proxy, for other (non-LEDR) devices that are
managed using the radio’s out-of-band Service Channel and directly

connected at some point to a radio’s Ethernet port, or to a common hub
with a LEDR radio. In other words, the radio network can be configured
for seamless integration of other IP-manageable devices by responding
to ARP requests and/forwarding IP traffic directed to those devices.
See the
route command on Page 77 for information on other necessary
configuration steps to allow for IP connectivity to LEDR radios and
associated devices using the radio’s network-management channel.

Background information on bert command:
The bit error-rate test command, bert, is used to evaluate the link
between the LEDR data interface and the customer premises equipment
(CPE). When used, the LEDR radio will send a test pattern out of the
LEDR FT1/E1 Data Interface lines towards the CPE while simultaneously attempting to receive the same pattern back from the CPE. For
example, you can loopback the CPE’s external data device’s I/O, then
issue a
bert command to the LEDR radio to check the integrity of the
wire connection. The test pattern can be user-selectable. (See bert command Options above for further information.)
NOTE: The bert command will not test or evaluate the integrity of the
LEDR radio link. (See “BENCH TESTING OF RADIOS” on
Page 122 for further information.)
NOTE: When operating FT1 or FE1 interfaces, this command tests all
T1/E1 timeslots without regard to the timeslot command’s
configuration.
bootBoot from Active/Archive Software
Usage:
boot [<1|2|-s|-o>]
This command is used to view or change the radio’s active software
image. If
2) is displayed. A selection of 1 or 2 after the command (e.g.,
boot is entered alone, the currently active firmware image (1 or
boot 2) ini-
tiates a reboot from that image. (A message appears to confirm that you
wish to reboot the radio firmware.) Upon reboot, the radio and all radio
functions are restarted in a manner similar to turning the radio power off
and then on again. The radio is taken out of service until it re-initializes,
and the link loses synchronization until the reboot process completes
and the demodulators at both ends reacquire the radio signals.
A choice of software images allows booting an alternate version of radio
software. The ability to have two radio-resident software images allows
radio software reprogramming over-the-air and the ability to restore
operation to the original software if required.
Subcommands:

clkmodeClock Mode (Subrate Radios Only)
530
FT1
E1
Usage:
clkmode [<internal|exttx|looped|extdce>]
This command displays or sets the source of the radio’s transmit clock.
For synchronization purposes, several different clocking schemes can
be used. See Table 10 on Page 23 for the combinations of radio bandwidth, data rates and modulation types that are available for subrate
radios. Table 11 on Page 24 shows the combinations available for full
rate radios.
Subcommands:
internal—Internal oscillator sources TC; RC derived from far end
of radio link (default).
exttx—ETC accepted from external equipment on EIA-530 inter-
face; RC derived from far end of radio link.
looped—Recovered RF (RX) clock; TC is synchronized to RC;
RC is derived from far end of radio link. Note: Do not use looped
clocks at both ends of any radio link.
extdce—ETC and ERC are accepted as inputs on the EIA-530
interface.
NOTE: Earlier versions of the software may display the Clock Mode
as NORMAL instead of INTERNAL.
Firmware Version 2.4.0 and Later – Use the
clkmode command to
determine which port has been selected to drive the timing at the interface.
Firmware Version 2.3.1 and Earlier – This command allows the various possible clock sources to be prioritized. As timing sources become
available, the highest-priority source will be chosen by the system. If
attaching to the network or equipment that provides timing, a universal
form of the command would be
clkmode 1 2 3 4 internal. If attaching to
equipment that will provide looped-back timing, a universal form of the
command would be
clkmode remote internal. If both ends of the link pro-
vide looped timing, the internal clock source should be selected at one
end by entering
clkmode internal. Note that at least one end of the link
should have either network or internal timing selected.
MDS 05-3627A01, Rev. DLEDR Series I/O Guide55
Page 64
NOTE: Firmware versions 2.3.1 and earlier, require that this parameter
be properly configured for correct operation of the link. More recent
firmware versions do not require that this item be manually configured.
However, the
clkmode command may still be used to determine which
port is being used to drive the timing.
Firmware Version 3.0.0 and Later– The

Usage: con (baud [300|1200|2400|4800|9600|19200|38400|115200]) (parity
[none|even|odd])
This command sets or displays the CONSOLE Port’s operating parameters. The
CONSOLE Port data rate is set or displayed using the baud sub-
command. The parity is set or displayed using the
The default setting is 9600 bps, no parity, 8 data bits and 1 stop bit.
This command is used to get or send a radio configuration file.
The radio stores its configuration data in a file that you can download
using the
config send command. The output can be directed to a file or to
the NMS window, either in a Telnet session or a serial NMS session.
The
config send command allows sending the configuration file over the
Ethernet management channel and storing it on a PC running a TFTP
server.
Subcommands:
send—Upload entire radio configuration file to host (includes all
radio-specific data)
get—Download radio configuration file from host (DOES NOT
download radio-specific data)
getall—Download entire radio configuration file from host
(including all radio-specific data)
Radio-specific data includes IP address, network settings, frequencies,
target power thresholds, calibration data, and IP routing table.

Group [<0-99>]
Demodulator: ERROR FREE
Savail: 1036
Sunavail: 0
ES: 0
SES: 0
Page 69
This command sets or displays the network group in which the radio is
operating.
Example Response:group: 1
In a typical system, all the radios would operate in the same group,
allowing the flow of network-management and orderwire activity
between radios and from one radio link to any other in the system. At a
repeater site, all radios must be set to the same “group number” (and not
group zero) for this flow of information to take place. Setting group
numbers differently in repeater systems isolates links from each other
from a network-management perspective, allowing segmenting networks and controlling the flow of network-management information.
Across a radio link, groups can differ from each other; only radios physically connected by Ethernet cables to each other or to the same hub
must have the same group number to intercommunicate.
Setting a radio’s group to zero prohibits all network management traffic
from flowing to and from that radio’s Ethernet port.

Each radio stores two independent firmware files that control the radio’s
operation. The radio uses one of the files as the active software, which
is running. The other software file is inactive and is not running. The
ability to have two firmware images allows firmware reprogramming to
be done over-the-air and provides the ability to restore operation to the
original software if required. The

NOTE: 1E1 through 4E1 data rates are not supported when using the
interleaveInterleave
EIA-530 interface. The maximum EIA-530 data rate is 768
kbps.
Usage:
interleave [1-12]
This command is used to set or display the interleave depth. The depth
range is 1–12 with settable values of 1, 2, 3, 4, 6 and 12. Default setting
for Subrate is 2, Default setting for Fullrate is 12. The interleave setting
must match at both ends of a radio link, or the link cannot synchronize
regardless of any other radio settings or signal strength. Larger interleave settings cause longer link latency; in latency-sensitive applications, interleave value should be reduced to as small a value as is
possible while maintaining good link performance (See the
g821 demod
command).
Example Response:
interleave: 1
Background:
In digital communications, interference often occurs in the form of short
noise bursts. These bursts normally corrupt a series of consecutive bits.
Interleaving is a digital algorithm that allows Forward Error Correction
(FEC) to better handle bursts of noise. Interleaving reorders the data so
that the symbols that would normally be neighbors in a given block are
spread among multiple blocks. FEC works on a block of data of a specific size and can properly correct errors as long as the number of errors
is small enough. With interleaving, the number of errors that occur
within a single block is reduced, thereby allowing the FEC to more
effectively correct burst errors.
The value of the interleaver function should not be changed unless there
are latency limitations for the radio link. If low latency is required, then
the interleave can be changed, but the ability to correct for the influence
of burst-noise on the BER will be reduced.
This command sets or displays the Internet Protocol (IP) settings for the
LEDR radio. The subcommands allow you to set the IP
mask
, IP gateway, or IP port. The port setting determines whether IP com-
address, IP net-
munication to and from a particular radio occurs over the radio link or
via a PC (or other networked device, such as a router) directly connected
to the radio’s
ETHERNET port. See “Network” on Page 39 for additional

local—Enables a local digital loopback mode. With this test, incoming
bits on the EIA-530 interface are sent back out the radio’s
DATA con-
nector before the modem module. This can be used to verify proper
interconnection between the radio and the connected equipment. None
of the radio’s RF circuitry is involved in this test
. (This description
covers only EIA-530 operation.)
For T1/E1 operation, the local subcommand enables a local digital MUX
loopback in the radio transceiver’s FT1 Interface Board before going out
to the main transceiver board.

remote—EIA-530 Operation: Instructs the radio at the other end of the
link to “echo” all of the data it receives. This is an effective way of
testing the entire communications system, including the transmission
path over the air. (In the event of a communications failure with the
remote radio, the message “Remote Error” is displayed, and no loopback mode is selected.
T1/E1 Operation: The
remote subcommand mimics the ior subcommand
described below.
rf—Enables an RF loopback mode. This mode allows testing of the local
radio transceiver’s transmit and receive chain. The receiver is rechanneled to the transmitter frequency.
NOTE: RF loopback testing is a valuable diagnostic tool, but it should
not be considered an exhaustive test of the transceiver. In some
cases, interaction between the transmit and receive
phase-locked loops (PLLs) can occur, causing erroneous
results during testing. Changing the transceiver’s RF output
setting may resolve these problems. Also, in some configurations, insufficient signal strength for RF loopback testing may
exist.
In addition, on all LEDR radios except the LEDR 1400 Series,
the transmit and receive frequencies must be within the same
subband for RF loopback to function.
Variables:
ior—An abbreviation for “I/O remote”, refers to the remote line loop-
back. Remote loopback port selection is relative to the local port. The
radio link will translate any line mapping to select the correct physical
remote port to loop back, based on the selected local port.
linelist—Represents a list of local line interfaces. It can consist of a single
line number or line name, a comma-separated list of line numbers or line
names, a range of line numbers (i.e., 1–4), or if linelist is not given all
lines. See Table 19 on Page 59 for a list of line numbers.

rdntRedundant (Protected Operation)
The
rdnt command is used to manage protected operation of the LEDR
radio and display operating status.
Usage:
rdnt [subcommand] [arguments]
Subcommands:active
default
hitless
ip
mode
nsd
status
swxcvr
temp
mode
The following subcommands are divided into two groups: read only and
read and set.
Read Only:
active—Shows whether the currently selected transmitter is active or
inactive.
default—Displays whether the radio is the default radio in a protected
configuration.
status—Protected status of this radio and the sibling radio.
Read & Set:
hitless—Sets or displays the hitless (error-free) switching status of the
receivers. It can be enabled or disabled using the
hitless on|off command.
In protected operation, either receiver (regardless of which transmitter
is active) can provide data to the user data port(s) in hitless mode. In
non-hitless mode, only the receiver in the active radio provides received
data. Radios operated in a space-diversity configuration must be configured to use hitless switching.
ip—Used to set or display the IP address to be kept in the memory of this
unit of the associated (sibling) radio in a redundant pair of transceivers.
In other words, the
rdnt ip setting of the top radio in a protected pair must
be set to the bottom radio’s IP address for proper switching and network-management functionality.
74LEDR Series I/O GuideMDS 05-3627A01, Rev. D
Page 83
NOTE: The associated radio (sibling) IP address should be
programmed to the IP address of the other radio connected to
the Protected Switch Chassis. The associated radio IP address
is used by the redundant radio to share information between
the units. This address is necessary for warm-standby
switching. The associated radio IP address parameters do not
affect IP routing and forwarding, SNMP, or Telnet.
The rdnt swxcvr will not operate correctly if this parameter is
not set correctly.
mode [#]—Set or display one of three redundant operation modes
status—Shows the state of both radios. Two status lines are displayed;
This Radio and Other Radio.
swxcvr—Forces a switchover to the inactive radio transceiver. (The
newly selected unit becomes the active transceiver.) The
eter must be configured correctly on both radios in order for the
rdnt ip param-
swxcvr
command to operate correctly.
NOTE: The rdnt swxcvr command should not be used within 2 minutes
of a power-up to ensure reliable communications exist
between the two transceivers.
temp—Set or display an over-temperature threshold (final amplifier
temperature in degrees Celsius), at which temperature switchover to the
other radio occurs.
nsd—Enable or disable network self-discovery between the units in a
protected pair
Example Response for
rdnt {status}: This Radio = OK
rdnt {status}: Other Radio = OK
rdnt {active}: inactive

number or linename, a comma separated list of line numbers or line
This write command loads the radio application software (firmware)
into the LEDR chassis from an external resource using Trivial File
Transfer Protocol (TFTP). A TFTP server must be running on the network and properly configured to serve the necessary file(s). See
“OPTION 3: Uploading Firmware from a Remote Server via Ethernet”
on Page 97 for further details.
rfocalTransmitter RF Output Calibration Table
Usage:
rfocal <freq region#> <cal-point#>
This command starts the RFOUT Calibration Sequence and should only
be used when directed by MDS factory personnel.
CAUTION:This command is used to recalibrate the internal transmitter
power output metering circuitry and may affect the accuracy of
the power output level measurement. Contact the Technical
Services Department at MDS for further instructions
before using this command. Ask for technical publication,
Retuning Procedure for LEDR II Radios, P/N 05-3633A01.
Recalibration may be necessary if the radio’s transmitting
frequency has been significantly changed. For the LEDR 400
and 900 radios, this is generally a change of more than two
radio channels. In addition, it is very important to verify the
power calibration is incorrect on the new frequency by
measurement with a calibrated external wattmeter before using
this command.
The radio frequencies of the LEDR 1400 radio can be changed
without impacting the accuracy of the power metering circuit’s
calibration.

The route command is used to add, delete or modify the IP routing table
entries. Other radios in the network are automatically added to the
routing table using the radio’s “Network Self-Discovery.” Routing IP
traffic to other devices via the radio’s management channel can be performed by adding routes to the radio’s routing table.
Once the IP configuration is set using the
routing entries will appear in the routing table. The first of these routes
is the default route which has a destination address of 0.0.0.0. This route
is used when a more appropriate route is not available. Thus it becomes
the “catch-all” route. The second route that will appear is the default network route. This route has a destination address calculated by “anding”
the IP address and subnet mask together. The Next Hop address of this
entry will be the default gateway configured using the
the Interface will be the default port. This route is used to tell the radio
how to reach its base network.

Page 87
Background on this command:
The LEDR Series of radios can be configured to pass IP management
traffic across the radio’s raw service channel. A process called “network
self-discovery” automatically configures IP routes between all radios in
a network (provided that the
group command has been correctly config-
ured throughout the system. (See “group” on Page 60). Also, see the arp
command on Page 51.
IP management traffic routing allows configuring and monitoring
devices other than LEDR radios using the same management channel,
providing clean integration of SNMP, Telnet, TFTP, and other IP management methods via one channel that doesn’t use any of the customer
payload bandwidth of the radio network.
Routes must be added to the radios at two points in the system to support
routing IP traffic to and from the connected devices: 1. At the gateway
end (where the management station is located), and 2. At the destination
end. Routes are added to the radios using the same convention as used
in the MS Windows, Windows NT, and DOS operating environments.
The exceptions here are that a mask and port must be specified, as well
as the target and gateway IP addresses. At both ends, the command used
is exactly the same (see command Example 1, above). In the command
example given above, the route is being added at the gateway end. The
difference is that at the gateway end, the port is
end, the port is
eth. Routes do not need to be added at points between the
air, and at the destination
gateway and destination, because the radio network handles the routing
between radios via network self-discovery. However, in each radio, the
IP gateway must be specified as the IP address of the radio at the network-management gateway in the system.
NOTE: Gateway Settings in Connected Devices
In the connected IP-manageable device, use the local radio’s
IP address as the default IP gateway for the device.
NOTE: Routing in Protected Systems
Each route added to a protected radio must be added to both
units in the protected pair, as they are stored separately. The
radios in a protected pair proxy for one another depending on
which radio is active, so the routing functionality is unchanged
and either radio in a protected pair can be specified as the
gateway for a connected device; but if a protected LEDR radio
is removed for servicing, all the routing information must be
programmed in the remaining radio for proper IP management
functionality.

timeTime of Internal Clock
Usage:
time [HH:MM[:SS]
This command displays or sets the time of the radio’s internal real-time
clock. The radio’s real time clock operates from an internal lithium battery so it is running even if the radio has no DC power connected.
The real time clock is fully compliant with Year 2000 standards.
timeslotTime Slot Assignment
FT1
FE1
Select which timeslots to transmit. This command has two uses; in
Usage 1, the timeslots can be set or displayed. In Usage 2, all pending
timeslots are committed/made active.
The timeslots may be different at each end of the link. They will be
monotonically mapped; that is, Slot 1 is mapped to Slot 13, Slot 2 is
mapped to Slot 14, etc. To select timeslots 1 through 12, enter the command
timeslot 1-12.
Usage 1:
timeslot [-d] [slotlist]
Usage 2: timeslot -c
Variables:
–dDisable timeslot(s)
–cCommit pending timeslots
Modifications to the timeslot list are kept pending until all available
slots have been assigned. The user can choose to commit slots when the
last available slot is added to the pending list, or by using the
-c option.
(See Usage 2.)
The default action is to enable given timeslots. If no arguments are
entered, the currently active timeslots and pending timeslots are displayed.
If rearrangement of timeslots is desired, some simple rules must be followed when CAS framing is used. Refer to the chart below for this discussion, where “TS” = “Timeslot”:
TS00
TS01–TS15TS16TS17–TS31
1M1N
84LEDR Series I/O GuideMDS 05-3627A01, Rev. D
Page 93
If the timeslots are rearranged such that M is to the “left” of timeslot 16,
and N to the “right,” then the timeslot numbers at the other end of the
link must agree (M and N). They may be re-positioned within their part
of the E1 frame (to the left or right of TS16) but may not be moved to
the other side.
slotlist variable is a list of timeslots and can be a single slot number,
The
comma separated list of slot numbers, or a range of slot numbers (i.e.,
2-8). Timeslots can be entered in any order and are automatically configured. Extra slots will be ignored. Unassigned timeslots in the pending
list are signified by
MA (must assign).
NOTE: Enough slots for the full data capacity of the modem setting
must be specified or the link will not synchronize.
NOTE: FT1 timeslots are 1–24. E1 timeslots are 0–31.
NOTE: In FE1 mode timeslot 0 is always selected. When frame struc-
tures are selected that contain CAS (
fstruct 4-7) timeslot 16
must be selected.
trapfilterTrap Filtering for SNMP
Usage:
trapfilter [<critical|major|minor|inform>]

The vox command sets or displays the level/threshold at which the orderwire microphone will key the transmitter.
NOTE: When the orderwire microphone is spoken into, the audio will
be heard by all LEDR radios in the network which currently
have a handset plugged into the front panel handset jack. Only
one station can transmit at a time; the circuit is half-duplex.
Example Response:

This command displays users currently logged in to the radio operating
system.
6.5Disabling the Front Panel Alarm LED for
Unused E1 Option Ports
To disable the ALARM LED on the front panel for a particular E1 port,
use the commands found in Table 27 below according to the E1 port
number. When alarm events are pending, the alarm condition for the
unused E1 ports remains until a valid input signal (as defined by G.703)
is applied.

You must log into the LEDR radio as a user with “Administrator” privileges to execute these commands. If you are using a terminal program
connected to the radio, send one command sequence at a time to the
radio with a 5 ms delay between each line.

7.0STANDARDIZING RADIO
CONFIGURATIONS
7.1Introduction
Setting up and configuring a network of point-to-point systems can be a
frustrating task. To make the task easier and more predictable, the
parameters of one LEDR radio can be used as a template for other radios
in your system. You need only address the parameters that are site or
unit-specific, such as an IP addresses.
The
config command allows the user to upload/download the radio’s
configuration data from/to a PC. There are two classifications of configuration data—radio-specific data and standard data.
90LEDR Series I/O GuideMDS 05-3627A01, Rev. D
Page 99
Radio-Specific data is:
• Frequencies
• Target Power
• Thresholds
• Calibration Data
• IP Address
• IP Routing Table
• Network Settings
Standard radio data are the configuration parameters that are common in
all LEDR radios.
Both types of data can be uploaded and downloaded between the radio
and a PC. It is up to the user to decide whether to download both types
or just the standard (core) data. Once the data is on a PC, the file can be
edited off-line, for example, the configuration data, if desired. The customized configuration file can then be downloaded to other LEDR
radios in your system from your PC.
7.2Setup by TFTP
To use this function the user will need:
• A PC with a TFTP server running.
• The IP address of the PC running the TFTP server.
Finding IP Addresses
T o determine the IP address of a W indows NT/2000/XP computer , select
Run from the Start menu, and enter cmd. At the cmd prompt, type ipconfig.
(For W indo ws 95/98 platforms, select
winipcfg
ip command.
.) The IP address of the radio can be determined using the radio’ s
Run from the Start menu and enter
Downloading Procedure
To download the configuration data from the LEDR radio to a file
filename.txt) on the user’s PC, enter the following command:
Ideally, the process of updating a system would go like this:
1. Upload the current configuration data from each radio to a specific
file on your PC.
At radio 1
CONSOLE Port enter: config send radio_1.txt 1.2.3.4
At radio 2 CONSOLE Port enter: config send radio_2.txt 1.2.3.4 (etc.)
2. Upgrade the software on each radio.
3. Boot from the new software.
4. Download the saved configuration data from Step 1 back into each
radio using the
getall subcommand so that you will get both the stan-
dard and radio-specific parameters.
At radio 1
CONSOLE Port enter: config getall radio_1.txt 1.2.3.4
At radio 2 CONSOLE Port enter: config getall radio_2.txt 1.2.3.4 (etc.)
7.3Setup Through the DB-9 CONSOLE Port
You have the option of sending the configuration data to the CONSOLE
Port instead of sending it to a file on a PC. Then the terminal program
can be set to log the data as it is created by the radio. The advantage of
this option is that you do not need to use the TFTP server, routing, etc.
on the PC.
During the upload, the LEDR software will prompt you to begin/end
recording at the terminal program. You will also be prompted on how to
end a download.
When the
config get downloading option is chosen (standard data only),
the software will filter out all the radio-specific parameters as they come
through.
To upload the data to the
LEDR> config send console
CONSOLE Port:
To download only the standard data via the CONSOLE Port:
LEDR> config get console
To download standard and radio-specific data: LEDR> config getall console
