Electrical Safety CAUTION: Dangerous voltages exist in the AC power supply. Before installation activity begins, locate the AC power cutoff switch, make certain all on site personnel know the location of the power cut off switch in case of accidental contact. Make certain power is not on when performing the AC power connections. Do not remove the cover, plug or unplug the unit when the surrounding conditions are wet or when it is raining. Failure to follow these recommendations could result in death or serious injury to personnel or damage to the equipment. Follow all applicable local, regional and national codes when making AC power connections, grounding, and mounting of hardware. Outdoor mounted equipment, including antennas and cabling should never be installed during or prior to electrical storm activity. Any of these symbols may be used to mark a device as being electrostatic sensitive. Electro Static Discharge DRAFT FCC ID MXM-HIGHPOINT200 - 4 - WARNING: Use Electrostatic Discharge precautions (ESD). Static electricity can seriously damage this equipment. Damage from static discharges can be prevented with just a few simple precautions: a) Always use properly grounded wrist straps when handling the equipment. b) Workbenches where equipment is tested should have grounded antistatic mats. c) For equipment located indoors, tile floors around the equipment should be waxed with a static dissipative wax or grounded antistatic mats should be placed around the equipment racks. Equipment rooms with rugs should be avoided, however if it cannot be avoided, grounded antistatic mats must be placed around the equipment rack. d) Keep the equipment in the original packing material and sheltered until it is to be installed. e) Never use white styrofoam, clear plastic bags or paper to pack the units. Cellophane and masking tape should never come in direct contact with the units. Only use approved antistatic bags and styrofoam (pink in color) to pack and store the units (even temporarily or during transportation). f) Always ground the equipment to prevent static build up, this with also help prevent lightning damage. g) Do not handle the units unnecessarily. h) Handle defective modules with the same precautions as good modules.

The frequency ranges and transmit-to-receive frequency splits (approximately 100 MHz) are simply guidelines. The design is flexible enough to allow a variety of frequency ranges and Transmit/Receive separations to accommodate almost any channel plan in the 2.5 to 2.7 GHz frequency band.

They include a transposition of TX and RX frequencies as well as different TX and RX IF frequencies. The results are different local oscillator frequencies used in the conversion process. From a mechanical point of view, the two transceivers are packaged differently. The headend transceiver slides into a cabinet card rack in the base station cabinet and does not have to be weather tight (the cabinet is). Also the DC power for the headend transceiver is provided by a back-plane connection from a DC power supply located within the base station cabinet. The subscriber transceiver is mounted outdoors near the antenna and has to be weather tight and have adequate thermal mass for heatsinking purposes. The subscriber transceiver receives DC power through the IF cable, and therefore requires only a single cable to be installed between indoor and outdoor equipment. This requires extra circuitry to be added to the transceiver IF cable diplexer to extract the DC power for the transceiver. There is also a communications channel that is diplexed onto the IF cable at a low carrier frequency (500 kHz). The communications channel allows remote diagnostics and configuration of the transceiver by using a …

Reply to Correspondence Reference Number: 12808 731 Confirmation Number: EA96729 Applicant: Spike Technologies, Inc ____________________________________________________________________________________ FCC Item 1. 1.) Because of the different power output ratings / capability of the "HUB" and "SUB" units, they must be Certified under separate FCC ID's. (Please see FCC R&R Section 2.1043 which sets the guidelines for equipment of the same "Type".) Please respond by indicating which unit should considered under the current pending filing. A new and separate application for Certification should be filed for the other unit. Spike Reply to Item 1: The HUB and SUB transceivers work in tandem as part of the HighPoint BDS System. The HUB and SUB are electrically similar with the exception that the frequency plan is reversed. In other words the HUB transmits on the same frequency the SUB receives. And the SUB transmits on the frequency that the HUB receives. Therefore they are mirror images. We will drop the HUB power level to meet the SUB power level. FCC Certification was granted on our previous version (MXM-PRIZM100) pair of HUB and SUB radios under one file and FCC ID number. Spike is hopeful we can do the same here. ____________________________________________________________________________________ FCC Item 2. 2.)
