23) Verify telnet communications with the IWP card by terminating the serial connection by entering
‘~.’ (tilde .), which returns the prompt to ‘build@craftpc:~>’.
After the serial connection is terminated, enter ‘telnet bts’ to display the ‘bts:A->’ prompt. This
shows that you are able to set up a telnet session with the TurboMAX.
Terminate the telnet session by entering ‘logout’. This causes the TurboMAX to display ‘Connection
closed by foreign host’ and the prompt changes back to ‘build@craftpc:~>’.
24) Reestablish a serial connection with the TurboMAX by entering ‘cu –l ttyS0 –s 9600’. The
TurboMAX responds with ‘Connected’. Press the [ENTER] key to display the ‘bts:A->’ prompt.
25) At the ‘bts:A->’ prompt, enter ‘runtrxpost’ to test the TRX card(s). The resulting output contains the
output for the various TRX tests, including one line for each TRX that reads: ‘TRX CARD IN SLOT
<2, 4, or 6>: COMPLETED TRX POST OFFLINE TEST: <PASSED/FAILED>’.
26) Review the E1/T1 and BTS POST test results by entering ‘postReportE1Trx’. The TurboMAX
displays a summary of the E1/T1 and TRX test results, which should all appear as ‘PASSED’ except
those which appear as ‘NOT-RUN’.
27) Reboot the TurboMAX after running the POST tests by entering ‘reboot’ at the ‘bts:A->’ prompt.
28) Have the E1 or T1 link provider certify that the links pass a BER (Bit Error Rate or Bit Error Ratio)
test at 10
-8
or better over 20 minutes.
29) Reconnect all E1 or T1 cables disconnected to run the POST tests.
3.6 Performing Racal Tests
30) Perform the Racal Test procedures for the TurboMAX as described in the interWAVE Field
Maintenance Guide for the 16W TurboWAVE. The only difference is that the output power of the
TurboMAX is slightly higher.
3.7 Off-Line Commissioning of a TurboMAX Daisy Chain
This is an optional section, and is only required if multiple TurboMAXs are to be daisy-chained off of a
BSC, BS Plus, or NIB. If this configuration is used, each TurboMAX must be installed separately, and must
have off-line commissioning procedures independently performed. Once each TurboMAX is installed and
commissioned, the TurboMAXs can be daisy chained together.
31) Before connecting any TurboMAXs, ensure that they are all installed and off-line commissioned.
32) Ensure that all the TurboMAXs have been tested using the Racal Test Set.
33) Ensure that a different Abis link has been set for each TurboMAX using the Abis Manager time slot
has been set for each TurboMAX as follows:
After each TurboMAX has been Racal tested, enter ‘getFlashE1Chan’ at the Craft PC ‘bts:A->’
prompt. The TurboMAX displays the timeslot reserved for the LAPD signaling timeslot (default =
16).
To change this value, enter ‘setFlashE1Chan <timeslot>’ at the Craft PC ‘bts:A->’ prompt,
where<number> is any unassigned E1 or T1 timeslot between 1 and 31, or between 1 and 24,
respectively.
Note that interWAVE recommends the following Abis timeslot assignments: First TurboMAX in the
daisy chain, Abis timeslot = 16. Second TurboMAX in the daisy chain, Abis timeslot = 17. Third
