Installation & Methods MBTS Figure 2.1 Samsung CDMA BTS Unchannelized BTS provides RF interface to mobile PCS users BTS-1 . . . It is compliant to: J-STD-008 J-STD-0019 (packet) T1/E1 BTS provides wired interface to BSC via unchannelized (packet) T1/E1 BSC Unchannelized (packet) T1/E1 BTS-n Figure 2.2 2.1.1 2.1.1.
Installation & Methods MBTS 2.1.1.2 BSC WIRED INTERFACE FUNCTION BSC/BTS interfaces send/receive the packet information on the traffic information and control signals between BSC and BTS. The BSC/BTS interface supports either E1/T1 (copper or µ wave backhaul). The unchannelized method suitable for the packet data transmission is utilized as a frame structure, thus utilizing the full bandwidth offered by the T1/E1. 2.1.1.

Ensure the strap is properly grounded to the equipment ground plane. Do not touch the face of cards; handle cards by the edges or handles when available.
Installation & Methods MBTS h. With circuit breakers in the off position, install the PCU-B power supplies. No lights should be illuminated at this time. Note: refer to proper procedure for installing cards. i. Turn on the circuit breakers; the red fail light should be lit. j. Turn on the PCU-B’s on the front of the panel switch. Notice the red fail light is extinguished and the green power on light is lit. k. On the backplane of the rack, measure the voltage with a DMM at PWR1A and PWR2A.

Installation & Methods MBTS Appendix C Antenna Installation 1 ANTENNA INSTALLATION Selection of an antenna is made after determining the application, performance requirements, and location of the proposed system. Criteria for selecting an antenna and transmission system include operating frequency, radiation pattern, gain, polarization, and windload. Typical antennas used in the PCS band are Omni and directional.
Installation & Methods MBTS h. After securing the antenna-mounting platform to the rooftop, install the antenna using the manufacturer’s recommended installation material and procedures. i. Install the antenna-mounting bracket using the mounting hardware provided in the antenna mounting kit. j. Mount the transmit and receive antennas to the antenna mounting brackets. Torque the nuts and bolts to the manufacturer’s recommended specifications. k.
Installation & Methods MBTS 1.4 Cable Hoisting Obtain suitable hoist line that will adequately support weight of the cable. Refer to cable Manufacturers Installation Instructions for approximate weights per 100-foot (30m) length of various size cables. Use a cable pulley high on the tower to allow cable connection to antenna, and another pulley at the bottom of tower. Most lengths can be hoisted manually; however, a winch is recommended for heavy lifts.
Installation & Methods MBTS After the cable has been raised to the correct height, anchor it to a tower leg beginning near the antenna or masthead electronics. Attachment to lighting conduit or vertical angle iron is recommended for installation where tower members do not provide adequate or convenient hanger support. Space hangers one foot apart for the first three at the top of vertical run and three feet apart thereafter.
Installation & Methods MBTS Appendix D GPS Antenna Installation The GPS antenna with an N-Type connector, is typically a 3” diameter circularly polarized antenna with an integrated preamplifier. A +5 volt dc bias is required via the center conductor to provide dc power for the integrated low-noise preamplifier. Two GPS antennas are used for redundancy, the system will work with only one antenna with the signal being split to the two receivers.
