Digital Repeater Line DSP85 Series Product Registration Information The product serial number is located on the label on the bottom panel, near the power connectors. Record the serial number, model number, purchase date and point-of-sale company in the boxes in Figure P-1 below. Retain this manual, along with proof of purchase, to serve as a permanent record of your purchase.
Digital Repeater Line DSP85 Series Use the following guidelines when considering separation distances. • Place indoor antennas such that, under normal conditions, personnel cannot come within 20 cm (~8 in) from any inside antenna. Adhering to this minimum separation ensures that bystanders cannot exceed RF exposures beyond the maximum permissible limit for uncontrolled exposure. • Position outdoor antennas such that, under normal conditions, personnel cannot approach closer than 183 cm (~6 ft.).

Digital Repeater Line DSP85 Series is in the boot up process. A blinking green LED (two seconds on/three seconds off) indicates a filter configuration file is loading. IMPORTANT Do not unplug the repeater while it is in the boot-up process. 1.4 Local Communication Interface Ports To allow monitoring and control, Westell repeaters are equipped with four ports that provide external communication access: one ethernet, one DB-9 serial, and two USB ports.
Digital Repeater Line DSP85 Series 1.7 Ethernet This port is used to provide local or remote access to the GUI. 1.8 Monitoring and Alarms The DSP85 Series can be monitored via an ethernet connection using SNMP, SSH and/or HTTP protocols. Public safety DSP models have dry contacts for traditional alarm panel monitoring as well. 1.9 Circuit Operational Description The repeater uses a single down-conversion/up-conversion scheme. There are multiple RF amplifier stages before each down-converting mixer.

Digital Repeater Line DSP85 Series 2 Optimizing the System during Installation 2.1 System Setup Considerations Check all cables for shorts and opens. Verify that there are no cables with loose or poor connections. RF leakage could cause oscillation to occur under some conditions. Check the rooftop antenna (donor antenna), if directional, for proper alignment along the calculated compass heading. Typically, the directional antenna is aimed at the same site that your handset uses, but it may not always be.
Digital Repeater Line DSP85 Series 2.3 Important Installation Notes Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. This feedback can cause the amplifier to emit a continuous signal at maximum amplitude and, in some cases, interfere with normal operation of the cell site. It is important to consider the layout and placement of the system carefully.
Digital Repeater Line DSP85 Series 2.4.2 Antennas • Use omnidirectional antennas indoors, and locate them centrally with respect to the intended coverage area to minimize signal leakage to the outside. Use directional antennas indoors only in special cases when higher gain and directionality would be helpful and RF exposure limits will not be exceeded.

You must verify that the ethernet port on your laptop is powered. If your laptop is on battery power, the ethernet port may be inactive by default. If this is the case, plug the laptop into a 110 VAC source or change the power settings to enable the ethernet port when the laptop is using battery power.
Digital Repeater Line DSP85 Series Appendix A Attenuation and Dynamic Range Guidelines A.1 Donor Port If a repeater is installed in an area with very strong wanted and/or unwanted signals, ensure that the overall signal levels are optimized to be within the best operating range of the repeater. Avoid de-sensing of a nearby base station site. You can accomplish these goals by properly attenuating the antenna port(s) in the path of the donor antenna(s).

Digital Repeater Line DSP85 Series F.2 DSP85-250 and DSP85-251 Series Mounting The following diagrams illustrate the methods for mounting the repeater(s) in a typical wall or rack installation. Brackets are provided for both options. Rack mounting a repeater requires two brackets mounted to the front corners of each module, Figure F-2. Figure F-2: Rack Mounting Wall mounting uses four brackets, one at each corner.
Digital Repeater Line DSP85 Series Mount the cross band coupler on the wall close enough to the repeater modules to allow the RF jumpers to reach from the CBC to the repeaters. The attachment system used to anchor the CBC to the wall must be able to support at least 8.4 lbs (3.8 kg). Use a wall anchoring system for the repeaters that can support at least 42.lbs (19.05 kg) for each dual band module and 23 lbs (10.43 kg) for each single band add on module.
