58 -- ULTRA-SMALL EARTH STATION SYSTEM FOR SATELLITE COMMUNICATIONS. DUE 091195. POC NTT America, Inc., Head Office, 101 Park Avenue, 41st Floor, New York, NY 10178, 212/661-0810 also NTT America, Inc., Pacific and Western Division, 800 El Camino Real West, Suite 103, Mountain View, CA 94040, 415/940-6565. This public notice is to request suppliers to provide NTT with general referential information on similar products or technology prior to procurement of the intended product (mentioned below) by NTT. This public notice is also to request that any suppliers wishing to participate as a subcontractor in the procurement program of this product should declare their intentions to that effect. This public notice is not intended to guarantee public notification of procurement of the product. (1) Name: Ultra-small earth station system for satellite communications. (2) Overview: Ultra-small earth station system for satellite communications consists of a great number of ultra-small earth stations possessing excellent portability, hub earth stations (main/sub stations) that communicate with ultra-small earth stations, and supervising and control stations (main/sub stations) that remotely supervise and control the working status of stations as well as the status of communications. Requirements of the system are as follows: (i) System requirements: (a) Frequency band for satellite communications: Ku band (14/12Ghz) (b) Communications service: voice or low-speed data communications through one circuit (two-way communications) using one ultra-small earth station (c) Circuit connection methods: demand assign connection and pre-assign connection (d) Necessary functions: supervising and control over satellite communications networks and connection with general public networks (ii) Ultra-small earth station requirements Installation: (a) There are two types of ultra-small earth station installations, one is portable installation (transportable by human strength) and the other is fixed installation (b) Necessary functions: terminal interface for communications (iii) Hub earth station requirements: (a) Installation: fixed installation (b) Necessary functions: general public network connection interface (iv) Supervising and control station requirements (a) Installation: fixed installation (b) Necessary functions: supervising and control over ultra-small earth stations and hub earth stations. (3) Number of dealing: (i) Ultra-small earth station: approximately 2,000 stations (ii) Hub earth station: two stations (main and sub stations) (iii) Supervising and control station: two stations (main and sub stations) (This quantity is the current estimate; it may change during public notification of procurement.) (4) Contents of RFI: Applicants are requested to supply NTT with the following information on similar products, or on technology relating to the product mentioned above. (All supplied information will be regarded as non-secret information and may be disclosed to third parties in the form of, for example, inclusion in the corresponding Procurement Documentation, or may become available to third parties. In any case, NTT will not assume any responsibilities for possible disclosure or use of the supplied information.) (i) Technical information: (a) Electric Characteristics: system diagram, antenna gain, antenna off-beam radiation pattern, transmit output power, transmitting and receiving frequency range, frequency stability, modulation, operating threshold C/N and bit error rate, phase noise, bid rate, information rate, error-correcting system, coding system, interface condition between external equipment and this system, power consumption (b) Functional characteristics: function to supervise and control satellite communications networks, function to connect with general public networks, function to substitute when main/sub hub earth stations experience trouble, function to control transmitting power according to up-link signal attenuation (c) Mechanical characteristics: outward appearance when operated and transported, size, weight (d) Accessories (e) Electric/physical conditions; environmental conditions (temperature, humidity, power outlet, etc.), conform to VCCI* standard *VCCI is Voluntary Control Council for Interference by Data Processing Equipment and Electronic Office Machines. (Abbreviated VCCI) (f) Other: conform to the rules concerning technical standard conformity certification for specified radio equipment (an ordinance of the Ministry of Posts and Telecommunications), technologies that are included in design specifications to reduce the effect of interference to/from neighboring satellites (ii) Price and Calculation conditions: (a) Unit price and Calculation conditions for an ultra-small earth station: for portable installation type, for fixed installation type (b) Unit price and Calculation conditions for a hub earth station (c) Price and Calculation conditions for supervising and control stations (two stations). If these prices can be divided into hardware parts and software parts, please distinguish these prices between hardware parts and software parts, and describe precisely. (iii) Standard delivery period after an order is placed (iv) Sales results, (v) Others: (a) Troubleshooting support system, Maintenance support system (b) Active proposal that can contribute to NTT's business (5) Request for Declaration of the Intention of Subcontracting: Any suppliers wishing to participate as a subcontractor in the product procuremet program of NTT, is requested to supply NTT with the information listed below. After preparing a list of supplied information, NTT will provide the list to applicants who request the list; those who have responded to the request for supply of the information listed in Item (4); and to those who have purchased the Procurement Documentation relating to procurement of the product. NTT, however, will not assume any responsibility for outcomes arising from supply of the list. (i) Name of the applicant (ii) Place of contact (Address, name of the person in charge, telephone number, and facsimile number) (iii) The products and/or services that the applicant can supply as a subcontractor. (6) Deadline for Acceptance of Offers for Supply of Information and Declaration of Intention to Subcontract: 3:00 PM, September 11, 1995. (7) Language: Japanese or English (8) Information Offices: (i) NTT America, Inc.
