Problems With or Without a PCS Interface Present
This section deals with Test Systems that do not include a PCS Interface.
Mobile will not
camp on a Control
Channel.
❒
Verify that you have correctly connected the mobile to the Test System. See
“Connecting a Mobile” on page 38
.
❒
Verify that you have set the
System Type
field (on the CALL CONTROL screen) to
DCCH
.
❒
Verify that you have set the
Cntrl Chan
settings to match the capabilities of your
mobile.
❒
Verify that you have set the
SID
(System Identification number) to match the
programming of your mobile.
❒
Verify that the
Amplitude
field is set to a level that provides a Control Channel with
great enough amplitude for the mobile to camp on. This level may have to be adjusted
higher than expected if another strong Control Channel signal is being generated at a
different frequency near the mobile under test.
❒
Press the DUPLEX key to access the DUPLEX TEST screen. Verify that the
Input Port
field is set to
RF In
, and that the
Output Port
field is set to
RF OUT
.
These settings assume you are connecting the mobile’s antenna port directly to the RF
IN/OUT port of the mobile. If the mobile’s receive and transmit connections have been
separated for testing, set these fields according to the configuration you are using.
Message “DTC msg
not acknowledged
by mobile” occurs
during attempt to
page mobile.
(This assumes the mobile does register successfully.)
❒
Verify that you have selected the correct vocoder setting for your mobile in the
Voc:
field (on the CALL CONTROL screen).
❒
Verify that the
MS ID
field is set to
Phone Num
and that the correct phone number for
the mobile is entered.
Mobile successfully
answers page but
immediately drops
the call.
❒
The
Traffic Chan Assignment
settings are not compatible with your mobile. Be
sure to set the
Type:
,
Band:
, and
Chan:
fields for the traffic channel you want the
mobile to go to when paged.
The message
“Squelch Interrupt
Overfull. Press
MEAS RESET” is
displayed.
This message occurs because the Test Set’s squelch threshold is continually being
crossed by the digital signals from the mobile, overflowing an internal memory
buffer. This situation does not affect measurement ability or accuracy, and should
be ignored.
