Protection schemes:-
for the 3 schemes , there is a list of commands you should know for modification the state
of switching between the main and extension units
1) Lockout : this commands equals to switching off the unit, suppose that you apply lock out command on the extension unit , then if the main unit became faulty , then the link will
be down no protection available due to locking out command of ch0 , Gives abnormal condition indication, lock out command is available for the standby unit
2)Forced :to force the protection on one unit only, suppose that the main unit suffers from
HIGH BER then you can force the protection to the extension unit , then if you take the
corrective action for the main unit and HIGH BER alarm cleared, the extension
unit still the active unit due to the forced command , Gives abnormal condition indication, forced command is available for the active unit,
active unit ch1+forced command= spare unit ch1
3)Automatic switch: normal switching operation condition

Loopback:-
You can use this menu to do the following:-
1)IF you have communication alarm between the 2 sites as High BER, demodulator fail, modulator fail , RX fail you can use the RF loop back to
decide weather the fault is on your local site or from the remote site such that
IF you make RF loop and the alarms cleared and you have normal received
level then the problem will be on the other site
2)IF you have transmission alarm as AIS for a tributary carries a bts, and this
bts suffers from AIS, you can use tributary loopback to check the route
3)checking equipment (IDU, ODU , CONNECTORS AND IF CABLE)

3)Alarms Handling:-
to solve any of this alarms you should follow the following steps:-
1)Make RF loop to decide if the problem is in your site or in the remote site
if the alarms cleared and you have acceptable RX level at your local station
then go to the other site and do the following, you will make another RF loop
and this alarms will not be cleared then the problem will be on your site
to solve this problem follow this steps
2) check the connectors and the IF cable carefully ,then
3) Replace ODU after you checked the connectors and the IF cable
4) if the problem still exists then try to change the IDU and alarm will be cleared

last step: switch on the IDU after you plugged in all the cables(power, interfaces & IF)
3)Alarms Handling:-
Plug in the flash
card carefully to
the new IDU
170
-
other alarms:-
1)cable los: check the 2 IF Connectors and the IF cable carefully, if the problem still exists
,change IDU unit, then ODU if the problem still exists.
2)alarm replaceable unit type mismatch or 1.11.11.12.21 : ODU version is not compatible
with the software version installed on the flash card , to solve this problem you can do the
following a)change the new ODU with other one compatible with the flash card software
version b) activate the 2nd software version it may be compatible with the ODU
version and then reconfigure the link again
c)change the flash card with other one and its software version is compatible with the
new ODU
3)Internal communication problem: check the connectors, then IDU
4)los of alignment: a problem in the radio protection switching , this alarm appears in 1+1
HSB Configuration only, to solve this problem see slide 150
5)incompatible shifter: apply the right shifter value for the operating frequency see slide
127
3)Alarms Handling:-
171
-
some problems may cause HIGH BER alarms and loss of frame:-
1)alignment problem : the reason of this problem is bad weather conditions or the support
carrying the microwave is not well fixed , such that the RX level at both sites is not stable
this will cause High BER alarm
How can you identify that this BER alarm is due to alignment problem?
a)check the equipments at the two sites through RF loopback, then you will have
acceptable RX levels and alarms cleared this indicates that the equipments is good
b)open the power measurement table and monitor the RX levels for local and far ends
with their minimum, maximum and current values
c) the Rigger Must check that the line of sight is clear and there is no obstacles.
to solve this problem try to realign the link from the 2 sites using alignment tools to give
the best RX level at both sites, thus the BER alarm cleared and link is
3)Alarms Handling:-
172
-
some problems may cause HIGH BER alarms and loss of frame:-
2)Wave guide problem:-
the wave guide is rarely used in our network , this wave guide is used in nonintegrated
antenna, any cut in this wave guide will effect the RX levels at local and far end to be very
weak about -77 db which causes high BER
to solve this problem
Replace the wave guide with other one such that the RX level will be normal again and
the BER alarm will be clear
3)Interference problem:
This problem occurred when there is two microwave links have the same alignment and
same frequency, this will gives an interference problem leading to high BER alarm
3)Alarms Handling:-
173
-
some problems may cause HIGH BER alarms and loss of frame:-
3)Interference problem:
How can you identify the interference problem ?
1)switch off the transmission from your site and try to observe the RX level at the
remote site , you will have RX level (this RX level is not from your opposite site)
but this is due to interference problem with other link
2) switch off the transmission form the remote site and try to observe the RX
level at your local site, you will have RX level (this RX level is not from your
opposite site) but this is due to interference problem with other link.
from 1 & 2
you will observe that when you switch off transmission from any site, the other
site will receive signal , this means that there is interference problem
3)Alarms Handling:-
174
-
some problems may cause HIGH BER alarms and loss of frame:-
How to solve Interference problem?
a)avoid installation of links having the same alignment and frequency
b) using default frequencies : this frequencies can overcome the interference
problem the table below shows the default frequencies can be used for mobinil
bands.
3)Alarms Handling:-
175
Band Frequency high Frequency low
BAND 23 GHZ 23254000 22246000
Band 25 GHZ 25781000 24773000
Band 38 GHZ 38598000 37338000
-
some problems may cause HIGH BER alarms and loss of frame:-
4)Coupler problem:-
This problem occurs in 1+1 HSB configuration only , , if the coupler became
faulty it may effects the RX level at both sites it will make losses about -20 db
leading to high BER.
how can you identify that this is coupler problem?
a)check the equipments by RF loopback at the 2 sites.
b)remove the coupler form 1 site and observe the RX level at both local and far
ends, if the RX level became normal at both sites then the problem is in the
coupler
we can solve this problem by changing the coupler with new one and if you don't have spare available, you can remove the faulty coupler such that the link
