2 Description
The interWAVE TurboMAX is a high-power, low-cost, compact BTS used to provide WLL (Wireless
Local Loop), microcell expansion, and specialty GSM deployment. It complies with all relevant GSM
specifications related to Abis and Air (Um) Interfaces, so it can be used with any other GSM-compliant
BSCs and mobile stations. The TurboMAX is 25” (63.50 cm) tall, 11” (27.94 cm) wide, and 19” (48.26 cm)
deep.
The TurboMAX consists of a chassis, one IWP card, one E1 or T1 Trunk card, two or three TRXs, an
EEPROM RFD card, one Main Power Supply module, one Amplifier Power Supply module, one Clock
module, two Fan modules, a high-power Amplifier module, and a CMA (Cable Management Assembly),
which contains combiners, diplexers, and/or filters, and which routes external cabling into the TurboMAX
chassis. Figure 1 shows the front view of a fully-loaded TurboMAX.

3 Installation
3.1 Mounting the Chassis
1)
Mount the TurboMAX chassis as you would any other interWAVE chassis, either in an equipment
rack, on a wall, or on a table, as described in the WAVEXpress BTS Installation and Commissioning
Guide.
3.2 Verifying and Configuring the E1 or T1 Card
2)
When your TurboMAX is equipped with an E1 Trunk card, verify that the trunk impedance is set
correctly on the eight-position DIP switch on the edge of the E1 card. For 75 Ohm coaxial cable,
DIP switches 1, 2, 3, 5, 6, and 7 must be set to ON, and DIP switches 4 and 8 must be set to OFF, as
indicated on the DIP switch housing. For 120 Ohm twisted pair, all the DIP switches must be set to
ON.
If you have set the E1 Trunk card for 75 Ohm coaxial cable, you may also need to ground the E1
coaxial cable shields. Note that only one side of the coaxial cables should be grounded to avoid
ground loops. To ground the Port 0 Transmit shield, place a jumper across P9 pins 1 and 2. To
ground the Port 0 Receive shield, place a jumper across P8 pins 1 and 2. To ground the Port 1
Transmit shield, place a jumper across P10 pins 1 and 2. To ground the Port 1 Receive shield, place
a jumper across P11 pins 1 and 2.
3)
When your TurboMAX is equipped with a T1 Trunk card, configure the trunk for the cable distance
to the DSX1 T1 demarcation point using the eight-position DIP switch on the edge of the T1 card.
For Port 0, use DIP switch pins 1 – 4, and for Port 1, use DIP switch pins 4 – 8.
For Port 0, when the TurboMAX is connected directly to another WAVEXpress chassis or if it is
connected to a T1 DSX1 demarcation point at 0-133ft (0-40m), set DIP switch 1 to OFF, and set
DIP switches 2, 3, and 4 to ON, as indicated on the DIP switch housing. When the TurboMAX is
connected to a T1 DSX1 demarcation point at 133-266ft (40-80m), set DIP switches 1 and 2 to OFF,
and set DIP switches 3 and 4 to ON. When the TurboMAX is connected to a T1 DSX1 demarcation
point at 266-399ft (80-120m), set DIP switches 1 and 3 to OFF, and set DIP switches 2 and 4 to ON.
When the TurboMAX is connected to a T1 DSX1 demarcation point at 399-533ft (120-160m), set
DIP switches 1, 2, and 3 to OFF, and set DIP switch 4 to ON. When the TurboMAX is connected to
a T1 DSX1 demarcation point at 533-655ft (160-200m), set DIP switches 1 and 4 to OFF, and set
DIP switches 2 and 3 to ON.
For Port 1, when the TurboMAX is connected directly to another WAVEXpress chassis or if it is
connected to a T1 DSX1 demarcation point at 0-133ft (0-40m), set DIP switch 5 to OFF, and set
DIP switches 6, 7, and 8 to ON, as indicated on the DIP switch housing. When the TurboMAX is
connected to a T1 DSX1 demarcation point at 133-266ft (40-80m), set DIP switches 5 and 6 to OFF,
and set DIP switches 7 and 8 to ON. When the TurboMAX is connected to a T1 DSX1 demarcation
point at 266-399ft (80-120m), set DIP switches 5 and 7 to OFF, and set DIP switches 6 and 8 to ON.
When the TurboMAX is connected to a T1 DSX1 demarcation point at 399-533ft (120-160m), set
DIP switches 5, 6, and 7 to OFF, and set DIP switch 8 to ON. When the TurboMAX is connected to
a T1 DSX1 demarcation point at 533-655ft (160-200m), set DIP switches 5 and 8 to OFF, and set
DIP switches 6 and 7 to ON.

3.3 Verifying the Internal Cabling
4)
Verify that the clock, antenna, and the other RF cable ends are correctly tightened to 7 to 10 in. lbs.
(79 to 113N.cm).
5)
Verify the cable from the IWP card ENET connector to the external alarm terminal block on the
front of the TurboMAX chassis.
Application Note 16 – version 1.1

A pplication Note
3.4 Connecting External Cabling
6)
Connect the E1 or T1 cabling directly to the E1 or T1 card using individually-shielded twisted-pair
cables, using the standard RJ-48C pinout. The RJ-48C pinout is as follows: Pin 1 – Receive
Ring/Shield; Pin 2 – Receive Tip; Pin 4 – Transmit Ring/Shield; Pin 2 – Transmit Tip.
When you are connecting the TurboMAX directly to another TurboMAX or another piece of
equipment via an E1 or T1 port, make sure you use a crossover cable that connects the Receive leads
to the Transmit leads.
7)
The TurboMAX comes in two configurations: low-power, with a single antenna, or high-power, with
up to three antennas.
When you are adding an antenna to a low-power TurboMAX, connect the antenna to the N-type
connector on the Antenna Plate Assembly on top of the TurboMAX.
When you are adding antennas to a high-power TurboMAX, make sure you connect one antenna to
each of the three N-type connectors on the Antenna Plate Assembly on top of the TurboMAX. Since
one antenna is shared by the receive paths for all TurboMAX TRXs, and since one antenna for the
transmit path for each TRX, you must connect an antenna to all available N-type antenna connectors.
8)
If required by local codes, ground the TurboMAX chassis by loosening a nut inside the Cable
Management Assembly and tightening the grounding wire under the nut, per local requirements.
9)
Connect any customer-defined alarm inputs to the external alarm terminal block as follows: Make
sure the external alarm inputs use normally-open relay contacts. For Alarm Input 1, connect the
alarm relay across terminal block pins 5 and 6. For Alarm Input 2, connect the alarm relay across
terminal block pins 5 and 7. For Alarm Input 3, connect the alarm relay across terminal block pins 5
and 9.
10)
Connect external power to the two (Main and Amplifier) power supply units as follows:
When you connecting –48VDC to the two chassis power supplies, (1) set the circuit breaker on both
power supplies to OFF, and (2) connect the –48VDC leads from the power source to the terminal
blocks on the front of both power supplies. Leave the circuit breakers OFF.
When you connecting 110 through 230 VAC to the two chassis power supplies, (1) set the circuit
breaker on both power supplies to OFF, and (2) connect the AC cables from the power source to the
IEC 320 receptacles on the front of both power supplies. Leave the circuit breakers OFF.
3.5 Off-Line Commissioning
11)
Turn on power to the TurboMAX chassis by setting the circuit breakers on both power supplies to
ON.

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 ’ at the Craft PC ‘bts:A->’ prompt,
where 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
Application Note 16 – version 1.1
page 10
A pplication Note
TurboMAX in the daisy chain, Abis timeslot = 18. Fourth TurboMAX in the daisy chain, Abis
timeslot = 19.
Verify that the Abis timeslot has been changed correctly. Enter ‘getFlashE1Chan’ at the ‘bts:A->’
prompt. The TurboMAX displays the timeslot reserved for the LAPD signaling timeslot.
34)
Reboot each TurboMAX by entering ‘reboot’ at the ‘bts:A->’ prompt.
35)
After all TurboMAXs in a daisy chain have been assigned unique Abis LAPD links, connect them to
each other and to the associated BSC, BS Plus, or NIB with E1 or T1 links as described in Section
3.4.
3.8 Shutting Down the Craft PC and Disconnecting the Serial and
Ethernet Connections
36)
Terminate the serial connection with the TurboMAX by entering ‘~.’ (tilde .), which returns the
prompt to ‘build@craftpc:~>’.
37)
Exit the XWindows session by pressing [CTRL][ALT] and [BACKSPACE] simultaneously. At the
‘build@craftpc:~>”’ prompt, enter ‘exit’.
38)
At the ‘craftpc login:’ prompt enter ‘root’ to display the ‘craftpc:~#’ prompt.
39)
Shut down the Craft PC operating system by entering ‘shutdown –h now’. After about one minute,
the Craft PC displays ‘System halted’ and ‘INIT: No more processes left in runlevel 0’.
40)
Turn off the Craft PC by toggling the power switch. The serial and ethernet connections can now be
removed between the Craft PC and the TurboMAX.
41)
Inform the OMC operator that the TurboMAX is ready for on-line commissioning.
3.9 On-Line Commissioning
On-line commissioning of the TurboMAX requires that an on-site field engineer work with the OMC
operator, after installation and off-line commissioning.
42)
Verify that the TurboMAX is fully commissioned, that it is connected to a BSC, BS Plus, or NIB
network element, and that the OMC is communicating with the connected network element.
43)
Have the operator verify that the RF frequencies are cleared to transmit.
44)
Have the OMC operator download the TurboMAX configuring and correct software version and
operational parameters as defined in the WAVEView OMC Operations and Maintenance Guide and
the interWAVE Network Implemetation Manual.
45)
Have the OMC operator perform the following:
Create a planned cell in the OMC database corresponding to this TurboMAX. The planned cell
should at minimum include the Cell ID and LAC for the TurboMAX.
Define neighbor relationships for the planned cell.
Create a managed cell from the planned cell.
Set the TurboMAX parameters, including its base station identity code.
Set the TurboMAX Abis parameters, including the corresponding E1 or T1 card slot and Abis
LAPD link.

Note: The BCCH can be assigned to any TRX in the TurboMAX. The label ‘First TRX’
applies to the TRX to which the BCCH is assigned. The OMC operator determines which
physical TRX is ‘First’, ‘Second’, or ‘Third’.
Troubleshooting
Other than the POST testing done in Section 3.5, the TurboMAX TRXs, EEPROM RFD card, high-power
Amplifier module, and CMA (Cable Management Assembly) combiners, diplexers, and/or filters are
replaced as a unit. Contact Technical Support for detailed troubleshooting information.
