A pplication Note TurboMAX BTS Installing and Configuring Application Note AN – 16 Date December 13, 2000 Products Covered TurboMAX Applicable System Release 5.0 Subject TurboMAX Application Note Intended Audience Network Planners, Installers, and End Users Number of pages 15 1.1 Objective The TurboMAX BTS is being introduced as part of System Release 5.0. This document describes the TurboMAX, and gives instructions on how to install and configure it. 1.
A pplication Note 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.
A pplication Note 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.
A pplication Note 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.
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.
A pplication Note 12) Monitor the Power On Self Test (POST) by watching the front-panel LED sequence to verify proper POST indications. Figure 2 shows the normal TurboMAX LED boot sequence. Note that the TRXs are tested sequentially. Power on the TurboMAX.
A pplication Note 13) After bootup, verify that the front-panel LEDs are lit as follows: SCN (on IWP card only) lit, PWR lit, ON LINE on IWP and E1 or T1 cards lit, FLT not lit. Note that the ON LINE LEDs on the TRX cards are not lit until they are unlocked by the OMC operator. If the LED displays are different than that shown in this and the previous step, the TurboMAX has not passed the POST. Contact Technical Support for further information.

Connecting the Craft PC to the TurboMAX via the Serial Port 15) Power up the Craft PC, and allow the Linux operating system to bootup. 16) Logon as ‘build’, and start XWindows by entering ‘startx’.
A pplication Note 18) Verify the boot parameters by entering ‘bootChange’. A list of parameters appears as you press the [ENTER] key, as shown in Figure 5. ’.’ = clear field; ’-’ = go to previous field; ^D = quit boot device : qu processor number : 0 host name : craftpc file name : /home/target/vxWorks inet on ethernet (e) : 172.16.80.42:fffff000 inet on backplane (b): host inet (h) : 172.16.80.
A pplication Note 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’.
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.
A pplication Note Define the TurboMAX beacon TRX, and assigning ARFCN for each TRX. When the TurboMAX is daisy chained, setting the ‘E1 use type’, ‘Previous TurboMAX node’, and ‘Next TurboMAX node’ in the TurboMAX Manager View, and setting the ‘E1 Chan’ as the Abis channel in the Abis Manager View as described in the WAVEView OMC Operations and Maintenance Guide. The rest of the TurboMAX on-line commissioning requires that an on-site field engineer work with the OMC operator as shown in Figure 6.
A pplication Note 46) Provide the OMC operator with all part, revision, and serial numbers for the TurboMAX cards and modules. 47) Power down the TurboMAX by setting the Main and Amplifier Power Supply module switches to OFF. Have the OMC operator verify the changed state of the TurboMAX. 48) Power on the TurboMAX by setting the Main and Amplifier Power Supply module switches to ON. Have the OMC operator verify the changed state of the TurboMAX.
