The information in this chapter addresses some of the scenarios likely to
be encountered by Customer Field Engineering (CFE) team members
while performing BTS optimization and acceptance testing. This
troubleshooting guide was created as an interim reference document for
use in the field. It provides “what to do if” basic troubleshooting
suggestions when the BTS equipment does not perform according to the
procedures documented in the manual.
Comments are consolidated from inputs provided by CFEs and
information gained from experience in Motorola labs and classrooms.
1If the GLI LED is solid RED, it implies a hardware failure. Reset GLI by re-seating it. If this persists,
install GLI card in GLI slot and retry. A Red LED may also indicate no termination on an external
LAN connector (power entry compartment at rear of frame).
2Verify that the span line is disconnected at the Span I/O card. If the span is still connected, verify the
CBSC has disabled the BTS.
3Try to ‘ping’ the GLI.
4Verify the LMF is connected to the primary LAN (LAN A) at the LAN shelf below the CCP2 cage. If
LAN A is not the active LAN, force a LAN switch to LAN A by following the procedure in
Table 11-2.
5Verify the LMF was configured properly.
6If a Xircom parallel BNC LAN interface is being used, verify the BTS-LMF cable is RG-58 (flexible
black cable less than 2.5 feet in length).
7Verify the external LAN connectors are properly terminated (power entry compartment at rear of
frame).
8Verify a T-adapter is not used on LMF computer side connector when connected to the primary LAN
at the LAN shelf.
9Try connecting to the Ethernet Out port in the power entry compartment (rear of frame). Use a
TRB–to–BNC (triax–to–coax) adapter at the LAN connector for this connection.
10Re-boot the LMF and retry.
11Re-seat the GLI and retry
12Verify GLI IP addresses are configured properly by following the procedure in Table 11-3.

StepAction
1If LAN A is not the active LAN, make certain all external LAN connectors are either terminated with
50Ω loads or cabled to another frame.
2If it has not already been done, connect the LMF computer to the stand–alone or starter frame, as
applicable (Table 6-6).
3If it has not already been done, start a GUI LMF session and log into the BTS on the active LAN
(Table 6-7).
4Remove the 50Ω termination from the LAN B IN connector in the power entry compartment at the
rear of the stand–alone or starter frame. The LMF session will become inactive.
5Disconnect the LMF computer from the LAN shelf LAN B connector and connect it to the LAN A
connector.
6If the LAN was successfully forced to an active state (the cards in any cage can be selected and
statused), proceed to step 13.
7With the 50Ω termination still removed from the LAN B IN connector, remove the 50Ω termination
from LAN B OUT connector. If more than one frame is connected to the LAN, remove the termination
from the last frame in the chain.
8If the LAN was successfully forced to an active state (the cards in any cage can be selected and
statused), proceed to step 13.
9With the 50Ω terminations still removed from LAN B, unseat each GLI card in each frame connected
to the LAN, until all are disconnected from the shelf backplanes.
10Reseat each GLI card until all are reconnected.
11Allow the GLIs to power up, and attempt to select and status cards in the CCP shelves. If LAN A is
active, proceed to step 13.
12If LAN A is still not active, troubleshoot or continue troubleshooting following the procedures in 13.
13Replace the 50Ω terminations removed from the LAN B IN and OUT connectors.

The code domain power test verifies the noise floor of a carrier keyed up
at a specific frequency per the CDF file.
Code domain power is the power in each code channel of a CDMA
Channel. The CDMA time reference used in the code domain power test
is derived from the Pilot Channel and is used as the reference for
demodulation of all other code channels. This test verifies that
orthogonality is maintained between the code channels. When transmit

Test Equipment Preparation– continued
Agilent R7495A T est Equipment
Setup
B
This test equipment requires a warm-up period of at least 30 minutes
before BTS testing or calibration begins.
Using the Agilent E7495A with the LMF
The Agilent E7495A does not require the use of the 19MHz frequency
reference; if connected, it will be ignored. The Even Sec SYNC
connection is required.
The Agilent E7495A signal generator is only calibrated down to –80db.
In order to achieve accurate FER testing, be sure the RX setup includes
at least 40db of attenuation. This will ensure the signal generator will
output sufficient power to operate in the calibrated range.
Set the IP Address as described in Table B-1.
Table B-1: Set IP Address on Agilent E7495A test set
n StepAction
1Use the System Button > Controls >IPAdmin to set an IP address on the E7495A as 128.0.0.49,
and Netmask to 255.255.255.128.
Connections
It is recommended that you use a hub with BNC and RJ–45 connections.
[Suggested models: Netgear model EN104 (4 port) or EN108 (8 port).
Do NOT use model numbers ending with “TP”; those have no BNC
connectors.]
The LMF will connect to the hub which in turn is connected to the BTS
and to the Agilent E7495A.
Agilent E7495A to Hub – This is an Ethernet cable, RJ–45 to RJ–45.
LMF to Hub – Use one of the following cables to connect the LMF to
the Hub:
– Ethernet cable, RJ–45 to RJ–45 (be sure that the LAN card is set for
either AUTO or to use the RJ–45 only).
– Coax cable between LAN card and Hub. (Use a “T” on the hub and
connect a cable between the other end of the “T” and the BTS LAN
connection).
Hub to BTS – Use BNC “T” connector on the hub. [If your hub doesn’t
have BNC ports, use a BNC to UTP adapter.]

Follow the directions in the WinLMF program to calibrate cables.
– Calibrate the short cable (see Figure 6-12 or Figure 6-13) and two
10 dB pads to get a base line and then calibrate the TX and RX
setup. Since you need at least 40 dB of loss when doing the FER
test, the setup for RX is the same as TX.
ATP Setup
TX Path Calibration setup is shown in Test Equipment Setup (see

test equipment as configured to perform automatic tests. All test
equipment is controlled by the WinLMF via an IEEE–488/GPIB bus.
The WinLMF expects each piece of test equipment to have a factory-set
GPIB address (refer to Table B-9 and Figure B-9). If there is a
communications problem between the WinLMF and any piece of test
equipment, verify that the GPIB addresses have been set correctly and
that the GPIB cables are firmly connected to the test equipment.
Figure B-15 shows the connections when not using an external 10 MHz
Rubidium reference.

Downloading ROM Code
Exception Procedure –
Downloading ROM Code
This procedure is not part of a normal optimization.
Perform this procedure only on an exception basis when no alternative
exists to load a BTS device with the correct version of ROM code.
C
NOTE
One GLI must be INS_ACT (bright green) before ROM
code can be downloaded to non–GLI devices.
CAUTION
The correct ROM and RAM codes for the software release
used on the BSS must be loaded into BTS devices. To
identify the correct device ROM and RAM code loads for
the software release being used on the BSS, refer to the
Version Matrix section of the SCt CDMA Release Notes
(supplied on the tapes or CD–ROMs containing the BSS
software).
All devices in a BTS must be loaded with the ROM and
RAM code specified for the software release used on the
BSS before any optimization or ATP procedures can be
performed.
If a replacement device is loaded with ROM code which is
not compatible with the BSS software release being used,
the device ROM code can be changed using the LMF
before performing the BTS optimization and ATPs. A
device loaded with later release ROM code can not be
converted back to a previous release ROM code in the field
without Motorola assistance
If it is necessary to download ROM code to a device from the LMF, the
procedure in Table C-1 includes steps for both ROM and RAM codedownload using the LMF.
Prerequisites
Prior to performing this procedure, ensure the correct ROM and RAM
code files exist in the LMF computer’s applicable <x>:\<lmf homedirectory>\cdma\loads\<codeload#>\code folder for each of the devices
to be loaded.

Downloading ROM Code – continued
CAUTION
The Release level of the ROM code to be downloaded
must be the one specified for the software release installed
in the BSS. The release level of the ROM code resident in
the other devices in the BTS must also be correct for the
BSS software release being used. ROM code must not be
downloaded to a frame loaded with code for a BSS
software release with which it is not compatible.
This procedure should only be used to upgrade
replacement devices for a BTS. It should NOT be used to
upgrade all devices in a BTS. If a BTS is to be upgraded
from R15.x to R16.0, the upgrade should be done by the
OMC–R using the DownLoad Manager.
