- Description
- NA The John A. Volpe National Transportation Systems Center (VNTSC) is an organization within the Research and Special Programs Administration, U.S. Department of Transportation. In an effort to acquire equipment required to establish a communication terminal for application in Government civil aviation systems, the VNTSC is requesting information from industry sources. The focus of the requested information is on full-duplex microwave radio modem systems. This notice is not a request for bids or proposals. This request for information does not commit the VNTSC to any future acquisition activity. The VNTSC contemplates an initial procurement of at least ten (10) full-duplex microwave radio modem systems with anticipated delivery in the summer of 2004. Each microwave radio and included mode m (hereinafter referred to as modem) and an associated antenna with interconnections will comprise a communication terminal for application in various Government civil aviation systems. The modem shall be capable of operating in full and half-duplex in point-to-point configurations. The modem shall be a commercially available device modified to operate in the 5.091GHz to 5.150 GHz frequency band. Maximum authorized bandwidth (-3 dB points) shall be 500 kHz. When the modem is configured to exclusively support a 64 kbps data rate, the bandwidth (-3 dB points) allocated to support the 64 kbps data rate shall not exceed 100 kHz. The required data rates of 128 kbps, 256 kbps and 512 kbps shall be allowed greater bandwidth allocations, when necessary, within the 500 kHz limit. Assigned carrier frequencies shall be maintained within a tolerance of 6 2.5 ppm. The modem shall provide a minimum power of one watt to the antenna. The unwanted emissions of the transmitter shall be in accordance with the National Telecommunications and Information Administration (NTIA) Spectrum Manual paragraph 5.3.3 for digital modulation techniques over 1.71 GHz to 15.35 GHz. The modem shall maintain a Bit-Error-Rate (BER) of 10-6, or less, for the following set of synchronous data rates and corresponding minimum received power levels: (64 kbps, -101dBm); (128 kbps, -98 dBm); (256 kbps, -95dBm); (512 kbps, -92 dBm). The modem shall provide a means, such as a liquid crystal display, backlighted control pad or equivalent, for configuring and determining the status of all pertinent operational paramet ers. The modem shall include a means for configuring and determining its operational status via a TIA/EIA-232 asynchronous communication port or other computer industry standard interface. The modem shall include the capability of selecting one of a minimum of six levels of interleaving to be incorporated into the error-correcting algorithms. The dynamic range of the receiver shall be 65 dB or greater. The data interface of the modem shall be TIA/ EIA-530. The modem shall provide a transmit clock and shall also provide the capability to utilize an external source for the transmit clock. The modem shall include Built-In-Self-Test (BIST) features to monitor and display alarm/status. The BIST shall provide critical alarm/status via front panel indicators and alarm relays. The modem shall inc lude a Simple Network Management Protocol based remote monitor and control capability that communicates with and provides detailed results of the BIST. The modem shall operate using 115 VAC 610 %, 60 Hz 65 % power. The power required shall not exceed 100 W. The modem shall be 19-inch rack mountable and not exceed four rack units in height. The total weight shall not exceed 50 pounds. The modem shall operate as specified: 0?C to 50?C and 10 to 90 % RH, non-condensing. The modem, when rack-mounted, shall be capable of withstanding shock impulses of the type indicated in any orientation without subsequent malfunction (Operational: 5 g, 11-ms half-sinewave; Non-operational: l0 g, 11-ms half-sinewave). The modem shall not be susceptible to: an E-field emission of 10 V-m-1 over the frequency ra nge 14 kHz to 30 MHz; and an E-field emission of 5 V-m-1 over the frequency range 30 MHz to 5 GHz. The modem shall be subject to the same requirements imposed upon class A computing devices in the Federal Communications Commission (FCC) Regulations, Title 47, Chapter 1, part 15, subpart B. The specifications of all materials and parts shall have been derated to ensure that the modem will operate as intended over the full range of environmental and power conditions. The modem shall be fabricated from fungus-inert materials or have electronic assemblies conformally coated to provide an effective fungus resistant barrier. All metal surfaces on cabinetry, panels and structural parts shall be painted, plated or anodized to provide environmental protection. All marking shall be by silkscreen o r engrave-and-fill methods. The modem shall satisfy the following reliability and maintainability requirements: Mean Time Between Failures, including the BIST, shall not be less than 10,000 hours; Mean Time To Repair shall not exceed one hour; Mean Bench Repair Time shall not exceed 4 hours. Preventive maintenance shall not be required and the modem shall be maintainable using standard commercially available equipment. The modem design shall provide fail-safe features for safety of personnel during the installation, operation, maintenance and repair or interchanging of a complete equipment assembly or component parts thereof. Equipment design pertaining to personnel safety shall be in compliance with the appropriate requirements of the Occupational Safety and Health Act (OSHA) as identifie d in Title 29, Part 1910, of the Code of Federal Regulations. Firms involved in the design and/or manufacture of any of the above listed systems and/or components are encouraged to submit five (5) pages or less of product literature including a.) product descriptions; and b.) product capabilities. Requested information should be submitted electronically via e-mail to Shedd@volpe.dot.gov by August 21, 2003. Any questions should be directed to Alison Shedd, Contract Specialist, Phone: (617) 494-2631, Fax: (617) 494-3024, E-mail: Shedd@volpe.dot.gov.
