4INITIAL TURNUP
4.1 SECTION INTRODUCTION
This section describes the procedures required to turn up the MDR-8000 Microwave
Digital Radios after installation.
This provisioning part of the section describes provisioning options available with the
MDR-8000 software application. Provisioning allows for the definition, editing, and storing
of specific functions. The MDR-8000 provides the ability to provision equipment and facili-
ties through a series of Windows™-based screens and messages. The Provisioning menu
lists equipment and functions which may be provisioned. You should use only those provi-
sioning screens that are applicable to your radio.
4.2 RECOMMENDED SEQUENCE
Perform the following initial turnup procedures in sequence:
A. Install software on PC.
Software installed at the factory before delivery should not be overwrit-
ten by downloading to the radio controller at initial turnup. Refer to
Maintenance section on the attached CD for procedure to upgrade exist-
ing software.
B. Turn on the radio.
C. Establish communication between radio and USI computer.
Saving provisioning on disk provides a reference for any future provi-
sioning changes.
D. Provision radio.
Note
Note
Note

4.3 SECURITY MANAGEMENT
A password is not required to operate the MDR-8000. The radio is
shipped without a password and if a password is desired, it must be
entered using the Change Password screen. Once entered initially, the
password must be entered each time the user wants to access the provi-
sioning screens (level 1 password required) or download software (level
2 password required).
The MDR-8000 application software offers user password security management using two
different levels of passwords. User security deals with access level assigned to specific
users. The level of user security affects the type and number of commands an individual
user may execute. This prevents an unqualified user’s access to high-level commands.
Level 1 password allows the user to perform all tasks except downloading software. Level 2
password allows access to all functions and is the highest level.
4.4 LOAD MDR-8000 SOFTWARE ON PC
Before operating the user system interface (USI) for the first time, the programs contained
on the CD ROM must be installed on the PC. The installation process configures the PC for
its unique requirements and prepares it to run the program.
A. Insert CD ROM disk into PC.
B. On Windows desktop, double click on My Computer icon. My Computer
window displays.
C. In My Computer window, click on CD ROM icon. Files window displays
D. See Figure 4 - 1. Follow directions and load USI software on PC.

4.5 TURN-ON PROCEDURE
For user safety, user should become familiar with locations of power
distribution units and circuit breakers associated with the MDR-8000
radio.
Perform the following procedure to turn on the radio.
A. On power supply module, set PA
ON/O
FF switch to OFF. Yellow PA OFF
indicator will light.
B. On power supply module, set POWER ON 1/OFF 0 switch to ON 1.
C. On power supply module, set PA ON/OFF switch to ON. Yellow PA OFF

4.7 TEST PROCEDURES
The radio has been properly aligned and tested at the factory before shipment eliminating
the need for testing after initial turn-up. The only time testing and/or adjustment is
required is after a maintenance action such as removal and replacement procedure and/or
constant alarms requiring corrective maintenance action. The completed maintenance
action procedure(s) will reference any required test procedure(s).
4.8 PROVISIONING RADIO
Changes to provisioning do not have to be made in any particular order.
Open radio provisioning screens. On main screen, double click on tower icon. Status and
alarm screen displays. Click on Provisioning. Check current provisioning and change as
required. See Figure 4 - 4 for recommended sequence.

UNUSED CHANNELS ARE DEFINED AS CHANNELS THAT HAVE
NEITHER LOCALLY INSERTED DATA NOR PASS-THRU DATA ACROSS
THE REPEATER CABLE. SELECT OFF IF LOCAL DATA IS NOT
INSERTED AND THE CHANNEL HAS PASS-THRU DATA ACROSS THE
REPEATER CABLE (NOTE: SELECTING NM IN THIS CASE WILL
CAUSE THE DATA FROM THE REPEATER TO BE OVERWRITTEN
WITH AN AIS SIGNAL PRIOR TO TRANSMISSION).
USING THE REPEATER CABLE TO PASS DS1 DATA ON CHANNELS
5-16 IS NOT RECOMMENDED ON MDR-8000 RADIOS. PASSING THE
DATA THROUGH ON THESE CHANNELS WILL PREVENT
INDEPENDENT SWITCHING BETWEEN THE DS1 I/O AND THE RADIO
TRANSMITTERS. THE DATA SHOULD BE DROPPED AND
REINSERTED AT EACH REPEATER NODE.
Note
The term "LINE" is used to describe an input/output
signal at DS1/E1 rate (1.544 MB/S 2.043 MB/S). The
term "CHANNEL" is used to describe a multiplexed
signal, at a higher rate than DS1/E1. The inserted
channel is output of multiplexer circuit. The dropped
channel is input to demultiplexer circuit. The
multiplexer and demultiplexer circuits are located on
I/O interface module.
Note
If installation at both ends of a hop are complete except for connecting to customer inputs/outputs and it is desirable to have an
alarm-free system, alarm reporting on the incomplete connections can be disabled temporarily through provisioning. You can
communicate over the hop even if you do not have the radio connected to customer DS1 inputs; however, you will alarm unless
you select
OFF
to disable
INSERT CHANNEL
(located on the USI DS1 Facilities screen) for all equipped lines. Disabling the DS1
insert function disables both the lines and alarm reporting for the lines. After all customer connections are complete, alarm
reporting can be restored to normal. To restore alarm reporting to normal, set
INSERT CHANNEL
on DS1 Facilities screen to
ON
.

Note
If installation at both ends of a hop are complete except for connecting to customer inputs/outputs and it is
desirable to have an alarm-free system, alarm reporting on the incomplete connections can be disabled
temporarily through provisioning. You can communicate over the hop even if you do not have the radio
connected to customer OC3 and wayside DS1 inputs; however, you will alarm. On the OC3 Facilities screen,
set Alarm Disable TRANSMITTER (IN) A and/or B and RECEIVER (OUT) A and/or B to ON to disable OC3 alarm
reporting for all equipped wayside DS1 lines. After all customer connections are complete, alarm reporting
can be restored to normal.

4.9.1 Auto-Negotiation
MDR-8000E auto-negotiation is not a stand-alone function, and proper operation and use
of all available functions depends on the capabilities of the external customer equipment
that is connected to the radio. Just because an autonegotiation function is checked for pro-
visioning does not automatically mean that function is fully operable. The device on the
other end of the cable must also have the capability and be provisioned with a matching
function.
4.9.1.1 Auto-Negotiate
Auto-Negotiate details are beyond the scope of this supplement. The rule of thumb to fol-
low when unsure of what functions to check or change from factory default provisioning is
leave at default (all autonegotiation functions are checked). Full autonegotiation capability
is becoming standard for manufacturers of Ethernet devices.
4.9.1.2 Allow 10, 100, and/or 1000 Mb Half and Full Duplex
If in doubt as to the link speed and mode of the external device connecting Ethernet to the
radio, check all boxes for speeds and modes. If you know the external Ethernet device has
speed and/or mode limitations, check only the boxes that apply.
Auto-Negotiate is automatically enabled when Allow 1000 Mb Full Duplex is enabled.
Auto-Negotiate must be enabled (checked) when more than one link speed is selected.
4.9.1.3 Input/Output Flow Control Features
Checking the box next to Input/Output Flow Control enables input and output pause func-
tions and the forward errored or large frame function. These flow control functions are
described in the following paragraphs.
4.9.1.3.1 Input Pause Feature
See Figure 4 - 16. This feature makes the auto-negotiation function willing to stop receiving
traffic. When the radio input buffers approach overflow, the function sends a pause mes-
sage to the link partner that is transmitting data to the radio, telling the device to tempo-
rarily stop sending data. The link partner will stop sending data if the device has and is
provisioned with the Allow Option Pause function.
If the link partner is either not equipped with or is not provisioned for input pause, data
overflowing the registers in the radio will be lost, regardless of the provisioning for input
pause in the radio. Any time there is an overflow, the radio will alarm and indicate
Dropped Frames on the Performance Monitor screens.
4.9.1.3.2 Pause Feature
This feature auto-negotiation function willing to stop sending traffic. When the input buff-
ers on the link partner approach overflow, the link partner sends a pause message to the
radio telling the radio to temporarily stop sending data. If the Input/Output Flow Control
function is checked, the radio will stop sending out data.
4-31
4.9.1.4 Input Pause Feature
See Figure 4 - 16. Checking the box next to Allow Input Pause makes the auto-negotiation
function willing to stop receiving traffic. When the radio input buffers approach overflow,
the function sends a pause message to the ink partner that is transmitting data to the
radio, telling the device to temporarily stop sending data. The link partner will stop send-
ing data if the device has and is provisioned with the Allow Option Pause function.
If the link partner is either not equipped with or is not provisioned for input pause, data
overflowing the registers in the radio will be lost, regardless of the provisioning for input
pause in the radio. Any time there is an overflow, the radio will alarm and indicate
Dropped Frames on the Performance Monitor screens.

Checking the box next to Allow Output Pause makes the radio auto-negotiation function
willing to stop sending traffic. When the input buffers on the link partner approach over-
flow, the link partner sends a pause message to the radio, telling the radio to temporarily
stop sending data. If the Allow Output Pause function is checked, the radio will stop send-

Audio provisioning is required only if 4-wire audio equipment (external equipment not part of
the radio) is supplied and the external audio equipment is connected to audio port 1 J316 or
audio port 2 J317 on the radio backplane. These provisionable 4-wire audio functions should
not be confused with the 2-wire audio handset. The handset is fully operational after it is
connected to the TEL jack on the radio controller module, provided the radio is provisioned
Audio 1.
The most common audio provisioning is: 1:, 2:, or 3: AUDIO 1 0/0 Norm.
Note
The 2-wire handset is transported over Audio 1 only.
Note
0/0 – RADIO REQUIRES 0 dBm AUDIO INPUT SIGNAL AT CONNECTOR J316.

this operation is not checked,
controller does not respond when
RDS, RAS, or RCD is polled.
Check RSS to allow Controller to
respond when Remote Station

is not checked, Controller does not
respond when RSS is polled.
Un-check J310 Modem to enable XMT, RCV,

Note
Each network element controller with ELMC must first be locally provisioned with a unique ELMC
or remote address. The ELMC address is not related to MCS-11. Any name can be entered as long as
the name is a 5-character, alphanumeric word. The address is case sensitive. Space, dash, slash,
asterisk, and underscored characters are not allowed. If small numbers are used as addresses, then it
is necessary to fill higher order digits with zeros. For example, if the address is the value 1, then the
address must be entered as 00001. No address, or the same address used on multiple network
elements, prevents ELMC access to that/those network elements. The remote address can only be
pro-visioned and changed locally. Service-affecting functions, including operation mode, radio
configuration, and remote address, cannot be provisioned or changed remotely.

5.1 INTRODUCTION
This section contains information and procedures to aid in restoring the equipment to
its proper operating condition after it has been determined that a problem exists.
The following warnings and cautions apply while operating, performance testing, trouble-
shooting, or repairing the MDR-8000 series radios.
Short circuits in low-voltage, low-impedance dc circuits can cause severe
arcing that may result in burns or eye injury. Remove rings, watches, and
other metal jewelry while working with primary circuits. Exercise caution
to avoid shorting power input terminals.
XMTR Crystals should never be shipped as replacements without being
soldered and tuned up in an oscillator assembly board at the factory.
Units with the electrostatic-sensitive (ESS) symbol contain ESS
devices. Store these units in an antistatic container when not in use,
and anyone handling a unit should observe antistatic precautions.
Refer to the Special Precautions pages in the front of the instruction
book for detailed handling information.

RF flex coaxial cable requires special consideration. The electrical char-
acteristics of the coax can be affected if it is accidentally twisted or bent.
Provide mechanical support to prevent any weight or strain to the coax
and connector when connecting or disconnecting equipment. Loosen the
connectors at both ends of a coax section if one end must be moved even
slightly. SMA connectors should be secured in place fingertight, and
then gently tightened using a torque wrench with a 5/16 in. head set for 7
to 9 inch-pounds. The connectors should not be left fingertight.
Ensure that all antennas are properly aligned and waveguide is in
good physical condition.
Before performing procedures that might in any way affect transmis-
sion, it is recommended that the person performing the procedure
understand the FCC Rules and Regulations pertaining to the equip-
ment and be properly authorized to operate the equipment.
5.2 MAINTENANCE PHILOSOPHY
This section provides information and procedures for equipment maintenance down to the
module level. Module repair is not covered in this manual. A replacement procedure for the
crystal oscillator subboard on the transmitter and receiver modules is provided to enable
future use of the local oscillator at a different frequency in another application or at
another location. Use the drawings in the appendix and those in the station drawing pack-
age to support the procedures in this section
The use of maintenance procedures in this section may result from failure of a periodic
check, an alarm indication, or unacceptable performance. These problems should normally
be resolved as shown in the maintenance philosophy flow chart (Figure 5 - 1).

Alarm names are radio/alarm equipment dependent. The Alarm List found under NOC
Alarm Troubleshooting on the enclosed CD, identifies every alarm name indicated by the
above alarm display equipment, in alphabetic order. By clicking on the alarm name, the
user can go straight to the description, cause, effect, and action for that alarm, regardless
of where the alarm is displayed. The alarm list is a summary of alarms designed for use by
NOC personnel. Refer to the detail troubleshooting later in this section for more informa-
tion.
5.7 ALARM MONITORING AND INSPECTION
Perform the following checks whenever a station is entered:
1Verify that no alarms are lighted; only the green status indicators should be
lighted.
2Momentarily press LAMP TEST switch. Verify all indicators light.
Keeping records of errors and alarm history can be an aid to system
troubleshooting.
The local status alarms screen displays the alarms of the radio to
which the USI is connected, either physically or addressed via the
ELMC.
3Using the USI computer, check local alarms on the Local Status Alarms
screen.
Note
Note
5-8
5.8 RECOMMENDED PERIODIC CHECKS
Perform XMTR local oscillator frequency verification (Para. 5.18) and XMTR output check
(Para. 5.19) 1 year after initial setting and at 5-year intervals thereafter to correct possible
drift caused by aging.
5.9 RADIO TROUBLESHOOTING
The digital radio system is equipped with alarm circuitry and automatic switching (in hot-
standby, frequency diversity, and space diversity configurations) to provide protection
against loss of traffic. This automatic switching, coupled with adaptive equalization of mul-
tipath distortion, provides protection against equipment outage and propagation varia-
tions. Because of the finite life of electronic equipment, failures occur.
5.9.1 Troubleshooting USI Alarms
First alert for an alarm is normally the USI Status Alarm Screen. See Figure 5 - 3 through
Figure 5 - 12 for detailed alarm information and troubleshooting guidelines. After isolating
the fault to the most probable cause, replace module or repair as directed.
5.9.2 Troubleshooting RCVR Lockup Problems
The radio is operational when the RCVR is locked onto the associated farend XMTR fre-
quency. Normally lockup occurs within minutes after power is applied. Successful lockup is
indicated by not having the channel alarm (Chan Alm) lit on the RCVR front panel.
5.9.2.1 Slow Lockup At Initial Turnup
Slow lockup at initial turnup is defined as lockup occurring five minutes or more after pow-
erup. If the radio is non-standby/no space diversity (one RCVR in A side), replace the
RCVR. If radio is non-standby space diversity or hot-standby (two RCVRs, A and B sides)
problem is probably the XMTR at the farend of the hop. The most common cause of slow
lockup is incorrect carrier null. First try switching XMTRs. If this clears the problem, per-
form carrier null (Para. 5.20) and XMTR/PA output level calibration procedure (Para. 5.21)
on the off-line XMTR. If the problem is not cleared, replace the XMTR.
5.9.2.2 Slow Lockup During Normal Operation
Slow lockup after a bad fade or other temporary interruption is defined as lockup occurring
less than a second after RSL is restored. Troubleshooting this type of slow lockup requires
knowing what the RSL is. Check RSL using the procedure in Appendix G on attached CD.
If the RSL is at least 4 to 5 dB above RCV threshold, the two most probable causes are carrier
leakage and the RCVR local oscillator. Perform carrier null test (
Para. 5.20
) on the farend
XMTR. If slow lockup continues, remove and replace the RCVR crystal oscillator subboard.
If the RSL is below or 1 to 3 dB above RCVR threshold, wait until RSL improves to at least
4 to 5 dB above RCVR threshold before starting troubleshooting.
5-9
5.9.3 Troubleshooting Performance Screen Errors
Path and intermod problems can occur that cause errors to be indicated on the Perfor-
mance monitor screens that are not severe enough to generate an alarm on the USI Alarm
and Status screen. Errors of this type fall into two categories: burst and dribbling errors.
The performance screens can be a useful tool in troubleshooting a radio with and without
alarms being indicated on the Status Alarm screen.
5.9.3.1 Troubleshooting Burst Errors
Burst errors are defined as multiple errors in a very short time. Burst errors can be caused
by many things, including loose connections on cable or waveguide at either end of the hop.
An aging oscillator can cause burst type errors. Burst errors can be identified by a high
number of Errors and low number of Error Seconds on the Performance screens. The
most probable cause of burst errors is a loose connection. Check/repair all shelf and exter-
nal cables and check all waveguide connections The next most probable cause is the crystal
on the crystal oscillator subboard at either end of the hop.If the radio has both A and B
XMTRS and RCVRS and both A and B are indicating burst errors, the fault is at the XMT
end of the hop. If only A is equipped and indicates burst errors, remove and replace the
crystal oscillator subboard on the on-line RCVR.
5.9.3.2 Troubleshooting Dribbling Errors
Dribbling errors are defined as small number of errors over long period of time (no frame
errors). Dribbling errors can be caused by a path problem, such as interference or fading,
or by a hardware problem such as a XMTR or PA that is being over driven, or high phase
noise in the XMTR or RCVR oscillator. Dribbling errors can be identified by observing the
Radio CRC Errors (DS1), Radio Errors (DS3), Receiver Errors (OC3), or RF Receiver
Errors (ETH) fields on the radio Performance screen. Typically, less than five Errors to one
Error Second identifies the fault as dribbling errors. Try isolating the transmitter by
switching transmitters in a protected system. You can further isolate a transmitter by
changing output levels using ATPC and or dropping the output power out of the XMTR to
the PA by one or two dB.
The DS1 radio performance screen has a Repeater CRC Error Sec field that indicates
errors over the repeater cable.
Two troubleshooting tips: 1) errors are displayed on the USI at the receive end in which
they are detected, and 2) these specific type of radio errors are not propagated down the
path.

In DS1 and OC3/STM-1 2-fiber switched and 4-fiber switched radios, if the RCVR alarms do not clear within the CLA window, after
ten 30-second periods (10 switches) the controller switches the I/O Interface modules and another 5-second CLA window is
opened. If the RCVR alarms clear during the 5-second CLA window following the I/O switch, the CLA will activate at the XMT end.
1. If RSL is ok, look for a digital signal problem at the farend XMTR:
a. Check XMTR capacity key.
b. Remove/replace XMTR.
c. Remove/replace I/O Interface.
2. If RSL is low, there will be a RCVR RSL alarm along with any others:
a. Check for prolonged fade. Use USI RSL screen and check history. Worst fading times are early in the morning and
late in the evening.
b. Look for equipment failure at XMT end:
Check for bad XMTR/PA. Verify correct output power out of XMTR/PA. Is output power correct?
Yes, check for bad cable or RF switch at the XMT end.
No, remove and replace XMTR, PA, I/O Interface, in that order.
CLA can be caused by many things. Troubleshooting is RSL dependent. Problems that can cause a CLA follow.
1. Path problems, such as fading, refraction, interference
2. Frequency problems due to aging or bad crystal oscillator
3. Bad capacity key on XMTR
4. Bad RF cable
5. Bad RF switch
6. Bad I/O Interface
If RSL is normal, look for a digital signal problem at the XMT end. The RCV end will probably have Eye Closure and Frame
Loss alarms, but not an RSL alarm. Since the RCVRs are receiving a strong signal (but not a good signal) from the farend
XMTR, the RCVRs will probably be locked on frequency.
Is RSL above or below alarm threshold?
Above, go to 1.
Below, go to 2.
Clearing the RCVR problem does not automatically clear the CLA at the XMT end. The CLA can be cleared using the ACO
switch on the controller module or by rolling the mouse over RF Common Loss on the screen and double clicking.
Since this is a silent alarm at the XMT end, no other alarm should show up at the XMTR.
Both RCVRs at the other end have a problem and have switched the
XMTRs to try and clear it. If the RCVRs clear within a defined time frame
(which we will hereafter call the CLA window) after switching, the CLA
appears. if the RCVRs clear by switching or any other way outside of the
CLA window, the CLA does not activate, but switching continues.
If RSL is above alarm threshold, the first XMT switch occurs 5 seconds
after the problem at the RCVRs is detected. The 5 seconds following the
first XMT switch is the "CLA window". If the RCVR alarms clear during the
5-second CLA window, the CLA will activate at the XMT end.
Since the RSL at the RCVRs is ok, equipment failure at the farend XMTR is
the most probable cause of the RCVRs failing.
If RSL is below alarm threshold, the first XMTR switch occurs 30 seconds
after the problem at the RCVRs is detected. The CLA window is the first 5
seconds of the second 30 seconds. If the RCVR alarms clear during the
5-second CLA window, the CLA will activate at the XMT end.
Switching times vary, depending on RSL.

The Eye Closure alarm, Radio Frame Loss

to form effective 3-level troubleshooting tools. If
the radio is provsioned correctly, Eye Closure
(the first level) should be the first indication that
there is a steady stream of errors (more than
dribbling errors) being detected by the RCV
circuit in the I/O Interface module. The second
level is the Radio Frame Loss alarm. This alarm
indicates that the errors have increased to the
point that complete frames are being lost. The
third level, the Channel Fail alarm, is the most
severe level. This alarm indicates that the RCVR
can no longer lock on the farend XMTR. Even
worse, the overhead with command path and
Service Channel is lost, inhibiting communication
with the farend, making troubleshooting more
difficult.

A Channel Fail alarm occurs when RCVR(s) have lost lock and are not
locked on the signal from the farend XMTR(s). Loss of signal also means
loss of CMD path. The most effective method of troubleshooting this type
alarm is to have a technician at both ends of the hop. Farend status
viewing and controls must be performed at the farend site. This alarm can
be caused by a failure at the farend XMTR, RF path/antenna/waveguide
problems, or a failure in the local RCVR or I/O Interface.
Start by isolating the fault to one end of the hop or the RF
path/antenna/waveguide. If the farend XMTR is protected, switch XMTRs
and see if alarms at the RCVR end clear. If so, the problem is at the XMT
end and the path and RCV end are ok. If the RCVR alarms do not clear
(and/or the XMTR is not protected) proceed as follows:
1.
Observe RX (RSL 1) dbm on the analog monitor screen and compare the RSL level with the TYPICAL
RCVR THRESHOLD (DBM) BER = 10-6, for the type and capacity of radio, listed on Tabe 1-3, Physical,
Environmental, and Electrical Characteristics, in the General section of this instruction book. If the RSL is
too low (below the RCVR threshold), the RCVR will not lock to the farend XMTR. The problem is in the
farend XMTR, is an RF path problem, or is a farend or local antenna/waveguide problem.
2.
Troubleshoot farend XMTR.
If the RSL is above the listed threshold, troubleshoot the local RCVR. Start by isolating the fault to the RCVR
module or I/O Interface module.
a. Observe
RX (AFC MON)
voltage on the analog monitor screen. This is the correction voltage for the
crystal oscillator. The voltage should be -3.0 ±0.5 Vdc, indicating that the crystal oscillator is on center
frequency. If not, remove and replace crystal oscillator subboard on RCVR. If the
RX (AFC MON)
voltage is correct, the failure could still be the RCVR or the RCVR circuits in the I/O Interface module.
The most probable cause is the RCVR.
b. Remove and replace RCVR. The crystal oscillator subboard and capacity key must be removed from
the suspected RCVR and installed on the spare RCVR. If the alarm is stil not cleared, remove and
replace the I/O Interface module.

Loss of radio frame from RCVR in I/O Interface RCVR circuits. Before
starting, check USI for receiver Channel Fail alarms and Common
Command Path alarm. If there is a Channel Fail alarm, troubleshoot and
clear that alarm first. If there is a Command Path alarm, troubleshoot and
clear that alarm second.
1. Verify farend radio configuration. Is farend radio hot-standby?
Yes, go to 2.
No, go to 4.
2. Check for Radio Frame Loss alarms on both A and B.
Are there Radio Frame Loss radio frame loss alarms on both A
and B?
Yes, go to 3.
No, only A or B has a frame loss alarm, go to 4.
3. Switch farend XMTRs. Do alarms clear?
Yes, replace farend off-line XMTR.
No, replace local I/O Interface on alarmed side. Do alarms clear?
Yes, stop. Procedure is complete.
No, replace local RCVR on alarmed side.
4. Replace local I/O Interface on alarmed side. Do alarms clear?
Yes, stop. Procedure is complete.
No, replace local RCVR on alarmed side.
Note
Always troubleshoot and clear the most severe alarm first.
Channel Fail is the most severe, followed by Radio Frame
Loss and Eye Closure.

Errors are being received by the RCVR at a rate exceeding the Eye
BER threshold error rate provisioned on the radio configuration
screen. This alarm could be caused by a faulty XMTR (farend), radio
interference on the RF path (RFI), antenna/waveguide problem, or a
faulty antenna/waveguide problem, or a faulty RCVR/RCVR local
oscillator failure. Troubleshooting is configuration dependent.
1. Check for Eye Closure alarms on both A and B RCVRs.
Are there Eye Closure alarms on both A and B RCVRs?
Yes, go to 2.
No, only A or B has an Eye Closure alarm. The failure is on
the RCVR end. Go to 3.
2.
The problem is in the farend XMTR, is an RF path problem, or is
a farend or local antenna/waveguide problem. Start by isolating the fault to one end of the hop or the RF
path/antenna/waveguide.
a. Check farend for XMTR alarms. Troubleshoot and clear alarms (if any) at far end as required. Go to b.
b. Check farend radio XMTR configuration as follows:
Hot-standby XMTRs? Go to c.
Frequency diversity? Go to 4.
Space diversity? Troubleshoot farend XMTR.
c. If the farend XMTR is hot-standby, switch XMTRs and see if alarms at the RCVR end clear.
Do RCVR alarms clear?
Yes, the problem is at the XMT end and the path and RCV end are ok. Replace farend off-line XMTR.
No, the problem is a path problem or a problem at the RCVR. Go to d to isolate the path.
d. The problem may be RF interference (RFI) on the path. While observing the RSL on the RCV end Analog
screen, disable the farend XMTRs.
Does RSL drop at least 25 dB?
No, there is high RFI on the path. Eliminate the RFI source.
Yes, RSL drops 25 dB or more. The problem is a path problem, such as an obstruction in the path, or
a problem with the antenna or waveguide, or is a RCVR problem. Go to 3.
3. Isolate failure to RCVR crystal oscillator subboard or the RCVR module as follows:
a. At RCV end, observe RX (AFC MON) voltage on the analog monitor screen. This is the correction
voltage for the crystal oscillator. The voltage should be -3.0 ±0.5 Vdc, indicating that the crystal oscillator
is on center frequency.
If not, remove and replace crystal oscil lator subboard on RCVR.
If the
RX (AFC MON)
voltage is correct, replace RCVR module.
Do RCVR alarms clear?
Yes, stop. Procedure is complete.
No, go to 4.
4. Problem is in path (not RFI) or antenna/waveguide. Sweep waveguide at both ends of hop. Repair or replace
as required.

More delay in system than elastic buffers on DS1 I/O
Interface can correct.
1. Isolate the delay to local or farend. Delay in the farend XMTR is a possible cause in frequency
diversity configurations. Is the farend radio frequency diversity?
Yes, go to 2.
No, delay is probably a local problem. Go to 3.
2.
Verify there are no farend XMTR alarms. Troubleshoot and clear farend XMTR alarms first.
3. Check/repair waveguide/path.
4. Isolate delay to A-side or B-side I/O Interface. On local controller front panel, observe I/O ALM
indicators. The A or B I/O ALM will be lit for the side with the excessive delay.
5. Remove/replace RCVR on alarmed side.
6. Remove/replace I/O Interface module on alarmed side.
Note

Problem Possible Cause Possible Solution
Unusually slow communi-
cation in radio network 1. Normal network management
traffic is saturating the communi-
cations channel.
1. There may be too many radios
being managed within a single
region. Split the radio network
management into different
regions and backhaul the traffic
for each region through sepa-
rate channels.
2. Polling radios for PM data or
missed alarms too rapidly 2. Poll the radios more slowly.
3. Multiple remote software down-
loads in process 3. Download to fewer radios at a
time.
4. IP traffic other than network
management traffic being routed
through radio network
4 Configure external routers to
allow only network management
related traffic through the Man-
agement network of the radios.
Dynamic route updates (OSPF,
RIP) may attempt to reroute high
speed traffic through the TMN
network if a high speed ink fails.
Unable to operate con-
trols using SNMP To perform control operations, the
Manager must be registered as a
craft device.
Register the Manager as a craft
device. Manager registration type
can be changed as needed to type
‘ct’ to allow control operation and
then be changed back to ‘nml’ for
normal operation.
Can Read SNMP objects
but cannot Write to
SNMP objects
1. Incorrect community string 1. Use the correct community
string.
2. Insufficient SNMPv3 privileges 2. Use the correct privileges:
a) The TMN Interface supports 4
view levels. Use a SNMPv3 user
account that supports write
access to the selected SNMP
object.
b) Use the correct Authentication
mode.
c) Use the correct Privacy pass-
phrase.
3. If the TMN Interface is config-
ured for SNMPv2, the write
community string is probably
wrong.
3 Use the correct write community
string.

Can ‘ping’ the TMN Inter-
face but cannot communi-
cate with the NE using
SNMP, or can only see a
few SNMP objects (mib-2)
in the NE.
1. Using incorrect SNMP version at
manager 1. Note the TMN card ships in
SNMPv3 mode. If SNMPv2
operation is desired, it must be
provisioned for SNMPv2 using
the TUI.
2. If using SNMPv2, using the
wrong community string. If using
SNMPv3 using wrong user-
name/passphrase pair
2. Verify community string or user-
name/passphrase.
3. A corrupt SNMPv3 security con-
figuration file may have caused
the module to revert to the previ-
ous copy of the security configu-
ration or to factory defaults.
3. Check to see if another user-
name/passphrase combination
works. Check to see if the previ-
ous passphrase works. Check
the Default username/pass-
phrase combination. It may be
necessary to re-initialize the
security configuration using the
TUI. Reprovision accounts as
required, and after the changes
have been committed, force a
reboot to copy the new security
configuration into the backup
configuration.

Units with the electrostatic-sensitive (ESS) symbol contain ESS
devices. Store these units in an antistatic container when not
in use, and anyone handling a unit should observe antistatic
precautions. Damage to the unit may result if antistatic pro-
tection is not maintained. Refer to the Special Precautions
pages in the front of the instruction book for detailed han-
dling information.
RF flex coaxial cable requires special consideration. The elec-
trical characteristics of the coax can be affected if it is acci-
dentally twisted or bent. Provide mechanical support to
prevent any weight or strain to the coax and connector
when connecting or disconnecting equipment. Loosen the
connectors at both ends of a coax section if one end must be
moved even slightly. SMA connectors should be secured fin-
gertight, and then gently tightened using a torque wrench
with a 5/16 in. head set for 7 to 9 inch-pounds. The connec-
tors should not be left fingertight.

Modules may be removed or installed with shelf power
applied. However, exercise reasonable care to prevent contact-
ing adjacent modules. If clearances are narrow, consider set-
ting the power supply to OFF while the module is being
removed or replaced. (Before setting any switch to OFF, verify
that traffic has been protected.)
Before replacing any module, refer to Table 5 - 6 to determine the actions, other than phys-
ical replacement, required. If the module has any options (switches, subboards, etc.), refer
to the removed module so that the replacement module can be set up the same way.
Any module installed in the card cage, except those having front-panel cable connections,
can be removed by grasping the module handle(s) and pulling firmly outward. Modules
with front-panel interconnects can be removed in the same manner after disconnecting the
cable from the module being removed and moving the cable out of the way.
To install a module in the card cage, insert the module card connector edge into the appro-
priate card slot. Engage module handles in card cage and press on module handles until
they are latched and the card is fully seated. After installing a module with front-panel
interconnections, reconnect the cable(s) to the front-panel connector(s).

PURPOSE
See Figure 5 - 19 and follow the procedure to correct the transmit frequency of the crystal
oscillator on the UD-35() Transmitter module.
Allow a 1-hour warm-up period for radio and test equipment before starting applicable
tests or improper frequency adjustment can result. If waiting for initial alignment is
impractical, it may be performed after a warm-up period of 5 minutes minimum; however,
crystal frequency should be rechecked after full warmup.

5.20 IN-SERVICE XMTR CARRIER NULL ADJUSTMENT USING SPECTRUM ANALYZER
See the following figures and follow the procedure to adjust carrier null on the UD-35A()
Transmitter, in service. For out-of-service carrier null procedures, refer to CD.
Carrier leakage can be nulled in the MDR-8000 using any one of three
methods. Method 1 (the preferred method) uses a spectrum analyzer to
determine if carrier leakage is present while a modulated signal is
being transmitted (in service) and then nulling any carrier present.
Methods 2 and 3 require that modulation be removed and the carrier is
nulled while the transmitter is out of service. Method 2 uses a DVM to
measure carrier leakage. Method 3 uses a spectrum analyzer.
Using the spectrum analyzer Span controls, reduce the frequency span until the
Resolution Bandwidth (
Res BW
) reaches the value defined as the
Res BW for measuring
carrier
. At this
Res BW
, observe the spectrum trace for a carrier signal. If a carrier signal,
rising above the spectrum floor, 3 dB or more is visible, use the procedure to null the
carrier. If no carrier is visible, the carrier is sufficiently nulled.
Ensure that the radio, and specifically the transmitter unit, is
allowed to warm up for at least one hour operating in the
radio before performing carrier null adjustments.
Note
CAUTION
Possibility of
Service
Interruption
5-49
cCarefully adjust the spectrum analyzer to center the transmitter
spectrum.
As the spectrum analyzer’s frequency span is reduced and the flat top of
the spectrum fills the spectrum analyzer display, it is extremely impor-
tant to keep the spectrum display (with carrier signal if any) centered
so that the carrier signal (if any) will remain visible as the span is
reduced.

Adjustment of the carrier signal for minimum amplitude is
critical. Do not attempt to null the carrier signal until the
correct Res BW is reached. Incorrect adjustment can result in
loss of traffic due to slow RCVR lock.
gObserve the display at the correct
Res BW
for measuring carrier for a
carrier signal rising above the floor of the spectrum. Is a carrier signal
rising 3 dB or more above the spectrum visible?
No. STOP. This procedure is complete. Carrier is nulled to an
acceptable level.
Yes.
1) Continue to reduce the frequency span until the spectrum
analyzer shows a Res BW equal to or lower than the
Res
BW For Nulling Carrier
value shown in the table.
2) Alternately adjust the I Carr and Q Carr controls on the
XMTR module for minimum carrier amplitude. Refer to
the following typical scenario for adjustment tips/prob-
lems.
TYPICAL ADJUSTMENT SCENARIO
Refer to the following step-by-step adjustment of 3 DS3/64 QAM radio. In this scenario,
carrier null adjustment is required due to slow RCVR lockup following a deep fade. The
Res BW
for nulling carrier for the 3 DS3/64 QAM radio is 3 kHz as listed in the table.

Note
You must watch the trace carefully on the spectrum analyzer when adjusting
the I and Q carrier controls on the XMTR module. the I and Q carrier controls
are interactive and the slightest change on one control causes a change on the
other. You must alternate between controls until carrier null is obtained. The
direction to turn the controls is not defined. If for example, the carrier level is
dropping as you are turning the I CARR control counterclockwise, continue to
turn counterclockwise until the carrier level on the trace stops dropping and
then starts to go up. Then turn the Q CARR control counterclockwise or
clockwise until downward movement is seen on the trace and continue to turn
in that direction. Watch for the slightest change in direction and then move to

5.24 PA REMOVAL AND REPLACEMENT
See Figure 5 - 25 and follow the procedure to remove and replace UD-51() PA.
This is an out-of-service procedure when on a nonstandby
(unprotected) system. On a hot-standby or frequency diversity
system, switch traffic on the channel under test to protect. Use
front panel OVRD controls on AE-37() Controller to lock on-
line XMTR (opposite side from failed XMTR) on line.
To prevent monitor point errors, use caution to ensure that
the front panel removed from the PA is replaced on that
same PA. No two monitor point levels labeled on PAs are the
same. Erroneous output levels can result from installing the
wrong front panel and calibrating the PA to the level labeled
on that front panel.

5.26 CHANGING FREQUENCY
Crystals are soldered and tuned up in a crystal oscillator sub-
board at the factory.
Changing frequencies requires changing the crystal on the crystal oscillator subboard in
the transmitter and receiver modules. Changing out the crystal requires tuning the crystal
oscillator subboard. Tuning the crystal oscillator subboard is a factory procedure.
An RF frequency change may require re-tuning the diplexer. Re-tuning the diplexer is a
factory procedure.
5.27 CLEANING
Do not use acid, alcohol, or brushes to clean modules because
damage to the silkscreen labeling and antistatic coating can
result. Cleaning should be confined to the removal of dust and
dirt using a damp cloth.
Cleaning should normally be confined to the removal of dust and dirt using a soft bristled
(natural fiber) brush and a low velocity blower (such as a vacuum cleaner with a plastic
blower nozzle). Do not use acid or synthetic bristled brushes to clean modules that contain
electrostatic-sensitive components.
