• A fault exists in the communications link
between the BSC and the BTS.
• Alarm can come in as either Major or Critical.
• Can come in on the CF, TRX, or both.
• 90% of the time is due to a down or faulty T1.
• Can also result from a faulty TRX or loss of
communication from the BSC to the TRX.
NOTE:
Prior to troubleshooting this or any other Ericsson alarm, always perform a right
click on the alarm in Netcool and chose the ―View alarms at this Location‖
option to view all alarms at this site to see if this could be a secondary affect
caused by power, maintenance, ECT and always search CTS to see if there is an
existing Ticket on the site for this or any related issue.

As we can see the MO’s in this TG show multiple OML faults indicating a down or
dirty T1. The next step is to status the primary DIP for the site to determine if it is
blocked.

This indicates that this site has a dead T1 and a Ticket should be created and
escalated to Telco to test the circuit.

Open a CTS ticket on this site from the OML fault alarm. Paste this information
along with the RXASP printout and the Granite (ED) path into the Ticket and
send it to Telco to have the circuit tested. No further actions will be needed at this
point.
If the DTSTP printout shows the DIP as WO or Working, the DIP may be working
but taking errors. In this case proceed on to step 4, checking the quality of the
DIP.
NOTE: The primary DIP is usually numbered the same as the RXOTG.
However, sometimes the OML links are placed onto the secondary DIP at
the site. If this is the case, the primary DIP may show WO when a portion
of the site is down (when in reality it is the second DIP that has faulted out).
You may need to determine what the secondary DIP is (if it exists) and
status it. It is important to get the correct DIP information to the field / telco
group so the correct circuit will be tested.

The next step would be to check the quality of the DIP by running the
DTQUP:DIP=___; command to see if it is taking errors
The quality printout shows this DIP is taking errors in the N-UAS section which is
the Unavailable seconds for unacceptable and degraded performance level for
the near end (incoming direction). In this case a ticket will need to be generated
and sent to telco as well with this printout, the RXSP printout and the ED path.
Any errors in these fields indicates a faulty T1 that will need to be ticketed and
tested by telco.
If the DIP counters read all zeros with no errors, the DIP appears clean and you
have verified the secondary DIP’s, then create a CTS ticket to send to telco with
your notes and troubleshooting steps and have them test the circuit to verify. If
the circuit tests clean and the OML faults are still present then forward the ticket
to the field to have them check the TRX’s. If the circuit test clean and the OML
faults clear, wait about 20 minutes and status the site again. If the OML faults
clear then the site has restored and you can close the TT. If the faults return then
send the ticket to the field tech with your troubleshooting notes to have him
investigate the issue.
It is important to note at this point that the CF/TG number are not always the
same as the DIP number. Secondary T1’s will have a number different than that
of the TG. There can be 2 or more DIP’s assigned to a CF/TG. In these cases
you will need to run a few extra commands to find the correct DIP number to
status and include in your ticket. Consider the following example using the same
commands used on the previous example.

The first command to run when looking for a secondary DIP is the
RXAPP:MO=RXOTG-__; This will show you the range of RBLT3 device numbers
attached to each DIP listed in sequential order.
Look at the result printout and find the range of RBLT or RBLT3 devices listed.
Usually it is easy to tell if there is more than one DIP assigned because the RBLT
range will have a noticeable skip in the numbering. In this case, the devices start
with RBLT3-1560 through 1583 (first DIP). Then jumps to RBLT3-2160 through
2183 (second DIP). Then Jumps again to RBLT3-5496 through 5513 (third DIP).
To find the DIP number form these devise ranges simply divide any number in
the device range by 24 and that will give you your DIP number. 1560/24=65 so
60RB3 is your first DIP. Then
2160/24=90, so 90RB3 is your second DIP.
5496/24=229 so 229RB# will be your third DIP. Now we can status all three DIP’s
to see which one is faulty.

During a possible outage situation where you have multiple sites showing OML
fault off the same BSC you can run the RXASP:MOTY=RXOCF; (you can
replace CF with TG, TRX, TS, ect..). This command will give you a printout of all
the CF’s that are in alarm with the site and condition for a quick count of how
many sites are affected.

Along with the RXASP:MOTY=RXOCF; command you can run the
DTSTP:DIP=ALL,STATE=ABL; command to help correlate the DIP’s that are
down to the sites that are in alarm from the previous command during an outage
situation. This will give you a printout of all the DIP’s to the BSC that that are
blocked. You can also use this information to cross reference you DIP’s in
Granite (ED) for your circuit information. It is important to note that this printout
will give you all the DIPS at the BSC that ore ABL. Some of these may be switch
DIPs or secondary circuits not related to cell sites.

As we can see here the DIP is ABL and the State is AIS (alarm indication signal).
When troubleshooting this alarm you can also begin, as I have done here, be
running the RXASP command and use the DIP number as the TG number since
often times the DIP number and the TG number are the same. This may be a
shortcut to correlating a site and TG to your DIP. You can cross reference the
info in the switch (which we will cover next) or in ED to check accuracy. In this
case The DIP is not the TG number so we will have to find the site/devices the
DIP is connected to the long way by checking the devices and SNT (switching
Network Terminal) it is connected to.

To find all the DIP’s connected to this SNT and their range of devises connected
to them, you will need to run the NTCOP:SNT=EMT3-2; command. Scroll
through the DIP's connected until you find the one you are looking for. In this
case 81RB3.

This shows the status of the devise range which we can see is ABL. Also it
shows us that the devises are provisioned for those time slots under the config
column with the PC or P (provisioned Configured and Provisioned) next to them.
If they were not configured it would show NP (Not Provisioned). It is important to
note the Config status as if they were listed as NP then this DIP has not yet been
provisioned in the Switch and the only further action would be to send a Minor TT
to the switch to have them turn this DIP down until provisioned so we don’t keep
getting alarms on it.
From here we can now find the TG and site connected to the DIP.

To find the TG and the site from the previous info, run the
RXMDP:MOTY=RXOTS,DEV=RBLT3-1952; command. This can be ran on any
provisioned device in the range. Also, you can replace the TS (time slot) for TRX.
What this output shows us is that the there is a timeslot allocated to this rblt3
deice and it is RXOTS-79-9-4. 79 is your TG number, 9 is your TRX number and
4 is the timeslot number. With this in mind we can now run the
RXASP:MO=RXOTG-79; command since we know this is on TG 79 from the
printout. This will of course give us the site ID and the alarm situation for that TG.

Our status here shows that this TG appears to be alarm free. However we know
this is not the case. With Ericsson, when you have a secondary DIP that goes
down, it may not always show up in the alarm printout for the RXASP command
but that doesn’t mean it’s not in alarm. We can view all the radios and the
timeslots and their status by running the RXMSP:MO=RXOTG-79,SUBORD;
command to verify that this TG does in fact have a bad T1.

From this Printout we can see the TRX’s, subordinate timeslots, and their status.
As we look we can see that in the BTS column there are several timeslots that
are DIS or disabled as well as the CONF column where you can see the same
timeslots listed as UNCONF or unconfigured along with the LMO column with the
HEX code stating an issue. At this point with all the information we have we
would create a CTS ticket to send to Telco with the DTSTP, RXASP, and the
RXMSP along with the correct ED path for the circuit to be tested.
Looking at this we see that not all the timeslots are in order or on the same
radio. This is done to split the rescores from the different T1’s to each sector for
redundancy purposes.

Determine if the fault is service-affecting or if any other MO’s are in alarm by
looking at the alarm list for the parent RXOTG. If it shows ―BTS INT
UNAFFECTED‖, this will generally not be service-affecting and will not warrant a
critical ticket on the RXOCF itself
If any other MO’s show ―AFFECTED‖ alarm situations, then troubleshoot them
appropriately. The fault codes reflected by the RXOCF will aid in determining the
problems on any subordinate MO’s.
When the RXOTX or RXORX show ―BTS INT AFFECTED‖, it is out of service
(blocked). Usually the RXOCF or the parent RXOTRX will show a ―BTS INT
UNAFFECTED‖ but will not be blocked. However, because the TX and RX are
blocked, from an operational standpoint the TRX is out of service as well since it
has no operating transmit or receive function.
Look the fault code up in the maintenance manual fault list to determine what it
means. The manual may also direct you to pull the fault codes from the parent
MO’s that are showing unaffected faults to help further isolate the problem.

Note: The actual faults are listed at the end of the printout. From here we can
see that the fault in on RXOTX-195-0 and 195-1. The fault code is 1B4. We can
now reference our documentation to see what the fault is and what actions are
required.
Slide 35
3. Reference the Fault code
Fault No. AO TX I1B:
4
Fault name: TX antenna VSWR limits exceeded
Related fault:
SO CF I2A:8 – VSWR limits exceeded
SO CF RU:40 – Antenna
Description: When VSWR at CDU output exceeds the class 2 limit
defined in IDB with OMT (default value: 1.8), the fault SO CF I2A:8
arises with RU map "Antenna". When VSWR exceeds the class 1
limit (default value: 2.2), the fault AO TX I1B:4 arises on TX.
Possible reas ons:
Faulty IDB
Faulty CDU
TX antenna/feeder faulty or disconnected
Pfwd/ Prefl cables faulty
Measurement receiver in TRU/CU (in some cases) faulty.
Action
Reference the fault code given from our documentation to view the fault and see
what are the next steps to take. From our documentation we can see that this is
a VSWR alarm
Fault Internal 1A 4 ―TX Antenna VSWR Limits Exceeded‖
This fault means that the VSWR (voltage standing wave ratio) on the transmit
antenna or antenna feeder is too high. To keep the reflected power from burning
up the transmitter or power amplifiers, the transmitter is shut down. The RXOCF
will usually also show unaffected fault internal 2A 8 as well.
This fault is NOT remote-repairable. Even if it is a bogus alarm, generally any
blocking/deblocking of TX, TRX, CF, etc will only remove the alarm for a short
period of time, and it will return on the next periodic VSWR measurement.
Cut a ticket to the field with RXASP and RXMFP printout and explanation that TX
has high VSWR. The radio is out of service.

additional alarms for the MO’s that have
caused the channel failures.
• Can present as a Critical or Major in Netcool.
• Can also be caused by a down T1.
Slide 37
Recommended Troubleshooting
Steps
1. Right click on the alarm in Netcool and
chose the ―View Alarms At This Location‖
option to see if there are secondary or
correlated faults that may be causing the
Alarm.
1A. If there are no secondary or correlated
alarms, search CTS on the site for
previously opened tickets.
Usually these are accompanied by secondary and/or correlated alarms. These
can come in as Major or Critical alarms. If you do find a secondary alarm, no
matter the severity, troubleshoot that alarm as instructed before moving on to the
next step. If there are no other issues at the site then we will proceed to find the
correct TG for the site in the alarm.

From looking at the alarm we do not have the TG number to status the alarm
situation. However, we can see the Cell ID in the alarm. From that we can get the
TG number. By looking at the alarm we see in the text that the alarm is on
sd0379 on sector ―Y‖. We can query the cell with the site and sector information.
To find the correct TG to a cell in these alarms you must first run the
RXTCP:CELL=SD0379Y,MOTY=RXOTG; command. This will give you the TG
ID from the cell ID and the sector. We can now see from the printout that the
correct TG to status is 91 and status the TG with the RXASP command.

the status of the sectors and get our fault codes for the problem. Basically
working this issue like any other internal fault problem. You will need to run the
RXMFP:MO=RXOTG-91,SUBORD,FAULTY; command to get your fault codes
for these devises. We will run this command next.

We already know from the RXASP printout that the faults are internal on
RXOTX91-4 and 91-5. From here we can see that the faults codes on RXOTX91-4 and 91-5 are fault code class 1B2. We can now refer to our documentation
to see what this fault is and if it can be cleared remotely or if it will need a ticket
to be dispatched to the field.
Slide 42
5. Reference our documentation to find
the proper fault code procedure.
Fault No. AO TX I1B:
2
Fault name: CDU output power limits exceeded
Related fault:
SO CF I2A:9 – Power limits exceeded
Description: When TX power at CDU output is 7 dB lower than exp ected,
fault SO CF I2A:9 arises. When the difference is 10 dB, fault AO TX I1B:2
arises.
Possible reas ons:
There is probably a fault on the TX path. Other reas on: TX high temperature
or saturation (see AO TX I1B:12 and AO TX I1B:14).
Action: Try the following actions until the fault is corrected:
Check all TX cables, both inside and outside cabinet.
Check the CDU — CDU P fwd/Prefl cables.
Check the RU logs to see which TRU is emitting the fault.
Switch positions bet ween TRUs/CDUs to find out it is the units or the RF
cables that are faulty.
Reinstall the IDB.
From our documentation we can see that this is a CDU power limits exceeded
fault. As the procedure indicates, there is no remote action that can fix this issue.
At this point you would create a ticket in CTS and send it to the field with the
RXASP, and the RXMFP printouts and a statement stating the problem.
It is important to note that the RXASP printout will not always display active
alarms but their could still be resources down in the sector. To check this we
would run the RXMSP command for this TG.

Again if there are no alarms displayed on the RXASP command then we check
the sectors to see if the resources are available. In this case we can see the
sector is OOS and needs attention. Often times if a secondary DIP goes down,
the Cell Logic Availability alarm will present itself with no OML fault or other
alarms in Netcool or in the RXASP printout.

From the RXASP printout we can see that the permanent fault is on RXOTRX32-8 and 32-9. We can status the sector to confirm the ratios status if desired
with the RXMSP command. You can always attempt to restore the radio (or radio
function depending on the MO, TX, RX) by blocking the TRX, testing it, and then
unblocking it. This will give the radio another chance to load and restore. It may
restore for 10 or 15 minutes and then go back into fault. If this happens send
ticket to the field explaining that you have attempted unsuccessfully to restore it.
This is the case more often then not, and this will require either hardware
replacement or a hard reset at the site. We will now go over the procedure to
restore the TRX.
NOTE: If the permanent faults are accompanied by OML faults in this printout,
investigate the issue as a bad T1.

To try and attempt to restore the TRX you must first block it down along with all
its subordinate devices. Use the RXBLI:MO=RXOTRX-32-8,SUBORD: command
to accomplish this. The Subord on the end of the command is to make sure that
all devices within the TRX are down. When you run this command you will notice
that the switch capitalize the command before any other output is given. It is
asking you to confirm your request to block. You will need to enter a ; and then
return to confirm. Then it will give you the printout you see here confirming that
the TRX is blocked. The next step is to test the TRX with the RXTEI command.

When the test is complete it will printout one of these 2 responses. From these
we can see the pass or fail indications. If it returns as failed the next step would
be to create a CTS ticket with the RXASP, and test result printouts and send it to
the field. If it comes back passed then wait a couple of minutes and status the
sector with the RXMSP command and status the TG with the RXASP command
to insure that the sector has restored.
It is important to note at this point that the alarm in Netcool may clear after
blocking and unblocking even though the problem has not gone away. Also, If the
test passes and the sector clears there is a good chance that the alarm and the
alarm condition will return in 15 or 20 minutes. In that case create a ticket and
send it to the field with the printouts and all troubleshooting steps taken.

alarms can not be fixed or restored remotely, you would now need to create a
CTS ticket, paste the allip information in the ticket and send it to the field tech. If
the alarm is not present in the external alarm list, these alarms can also be view

RXOTS (Timeslots) can generate TS SYNC FAULT alarms when the span takes
slips, or the path between the transcoder and the TRX is disturbed (ie congestion
in subrate switch). Generally, the RXOTS MO’s will show OPER, but the
corresponding TCH’s will show BLOC. To clear the TS faults, you must block,
loop test, and deblock the affected RXOTS MO(s). It is also helpful to check the
DIP for errors to resolve the origin of the problem.
Here we see that RXOTS-25-3-2 has faulted
If the RXOIS is in alarm PERMANENT FAULT, proceed directly to document
―RXOIS: PERMANENT FAULT‖. A faulty RXOIS can cause RXOTS problems.
In general, if a site only has 2 or 3 TS in fault, you should be able to clear them.
If all the TS under a TRX are down or multiple (more than 7) are down on the
site, additional troubleshooting will be required.

• Will need to be cleared manually
• Does not require a CTS ticket
A threshold alarm from the BSC triggered when a certain number of traffic
channels are continuously busy or unavailable. These are usually due to
secondary faults or conditions at the equipment or site they are originating from.
T1 failure, radio issues, ect… These are not alarm conditions within the BSC,
rather they are just informational alarms telling a certain number of traffic
channels are down. There is no remote troubleshooting remedy for this condition.
The condition can be cleared manually by clearing the traffic channel alarm data
in the BSC.

• AP/CP can occur for a wide range of issues
• Can present in Netcool as Critical or Major
• Can sometimes require reporting to Outage
Management for a SIR
• Should always be ticketed after verification
AP/CP faults can come in for a wide range of issues as both critical and major.
The can be verified by running the ALLIP for both A1 and A2. The severity of
these alarms is not always represented well by netcool meaning just because it
presents as a major in netcool it still may be a critical issue. CP issue tend to be
more critical and less common then AP faults.

From the ALLIP A1 we can see that the AP process has stopped. This will
require an immediate ticket to the Switch and a call as well. Also, report to the
Outage management team. If the AP or CP have gone single sided, as in this
case, they will need to send a SIR notification for lack of redundancy. Also, check
the ALLIP A2 printout as some of the alarms will only present as majors even
though they are critical.

It is important to note that not all AP alarms are not this serious. Most are majors
with process errors or faults that can just be sent to the switch without callout.
However, anytime you lose redundancy with either the AP or CP, a callout will
need to be made and the Outage Management team advised.

MO FLT= LOOP TEST FAILED
MO FLT= LOOP TEST FAILED
• Occurs when a manual or automatic loop
test has been performed while the DIP
takes errors, or the path between the
transcoder and the TRX is disturbed
• Presents in Netcool as a Major
• Can sometimes be restored If it is not a
DIP issue

Recommended Troubleshooting
Steps
1. Retrieve alarm printout from parent RXOTG

As we can see from the printout RXOST-63-0-0 is affected. If the RXOIS is in
alarm PERMANENT FAULT, proceed directly to document ―RXOIS:
PERMANENT FAULT‖. A faulty RXOIS can cause RXOTS problems. Also,
always check the DIP for errors since this is likely caused by a faulty DIP. If the
DIP shows errors create a ticket and treat this like a regular DIP issue.
If the DIPs are clean you can try to block the affected TS, run the TEI test, loop
test, and then unblock the TS like we did with the TSSYNC faults earlier,

Block the affected RXOTS MO(s). Test the affected RXOTS MO(s) (NOT
REQUIRED, BUT RECOMMENDED) After a few seconds, a result printout
should appear with ―NO FAULT INDICATIONS. Run a Loop-Test on the affected
RXOTS MO(s). This tests continuity between the transcoder and the TRX/TS.
The result should be ―TEST SUCCESSFUL‖. If RESULT = ―ABIS PATH
UNAVAILABLE‖, you may have a faulty DIP or the DIP resources have not been
assigned correctly. If RESULT = ―TEST PASSED‖, the fault may have just been
transient. Proceed with unblocking

Unblock the affected RXOTS MO(s). It will show ORDERED, then after a few
seconds, EXECUTED if you are successful. Otherwise it will just return a NOOP
result. At that point you would have to create a ticket and send it to the field.

The RXOCF is currently in a maintenance mode, normally set locally by a tech in
the site.
1) If a tech has reported for maintenance on the site or there is a ticket cut
against this device or other devices in the site, notate the alarm as LOCAL
MODE.
2) If no tech has called in and no relevant ticket exists against site, cut ticket and
note this information. There are times that devices go into local mode due to
problems.
). The RXOCF is currently reporting that the cabinet door is open, hopefully by a
tech at the site.
1) If a tech has reported for maintenance on the site or there is a ticket cut
against this device or other devices in the site, notate the alarm as OPERATOR
CONDITION.
2) If no tech has called in and no relevant ticket exists against site, cut a minor
ticket and note this information. There are times that the door alarm contacts fail,
or the weather may be affecting the door seal.
Note, the RXMFP printout on the RXOCF will show an External Fault 2B 9
(operator condition).
