Typical Fully-Loaded TurboMAX Application Note 16 – version 1.1 page 3 pplication Note A 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. Application Note 16 – version 1.1 page 4 pplication Note A 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 page 5 pplication Note A 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.
