What should I do? What is a good result?
What does a good
result mean?
What if I do not get a good result?
A
Confirm EUM status Telnet to the CCU and
go to the CLI prompt.
Telnet is successful. Go to Test B. Check the upstream data path and
equipment, or go to CCU Troubleshooting on
page 145.
B
Verify the CCU
configuration for the
affected EUM
Check the Authorization
Table in the CCU.
Affected EUM ID is not
DENIED.
The affected EUM is
enabled and can transmit
and receive data. Go to
Test C.
If the EUM is DENIED, change its GOS to BE,
BRONZE, SILVER or GOLD. Retry Test B.
If the affected EUM does not appear in the
Authorization Table, but the default GOS is
BE, Bronze, Silver or Gold, then the EUM will
actually be
enabled, and Test B is a PASS.
Go to Test C.
C
Check the radio link to
the EUM
<ping> the affected
EUM from the CCU. Use
long and short pings.
No ping failures or time-
outs.
The radio link to the EUM
is likely good. Go to Test
D.
If there is no ping response, the radio link may
be down. Go to the local troubleshooting
procedures outlined in Table 32 on page 140.
If you are having partial ping failures, the
radio link may be poor. Go to Test D.
D
Telnet to the affected
EUM and, through the
CLI prompt, enter
<ra
rssi>
.
The RSSI value should
correspond to the
original installed value. A
signal > -80dBm should
provide robust service,
with a low transmission
error rate. Refer to
Permanent Configuration
File (CCU and EUM)
on
page 193 to find out how
to convert from RSSI to
received signal level in
dBm.
The radio link is
confirmed. The reported
problem will likely be a
PC configuration issue.
You may be able to
resolve this issue with
the end-user on the
phone. Alternately, go to
the local troubleshooting
process outlined in Table
32 on page 140.
