J -- J--PROVIDE PREVENTIVE AND REMEDIAL MAINTENANCE FOR COMMUNICATIONS FRONT END PROCESSOR (CFEP) AND AUTOMATED DIGITAL WEATHER SWITCH (ADWS) POC POC SSgt Anita Earthly, Contract Specialist, 334-416-5415, Contracting Officer 1Lt Artis Clayton, 334-416-5415. Headquarters Standard Systems Group (HQ SSG) intends to acquire hardware maintenance services for the Automtic Digital Weather Switch (ADWS) and the Communications Front End Processor (CFEP). The main focus of this contract effort shall be to provide hardware maintenance services for the ADWS and CFEP facilities to ensure that the ADWS and CFEP are operational 24 hours per day, seven days a week. The ADWS and CFEP shall be required to maintain a system of effectiveness level of 99.5% and a component efffectiveness level of 95%. Top level objectives shall include quality Preventive Maintenance and Remedial Maintenance services, developing maintenance records and documentation, enviromental, security and safety compliance with Air Force standards and cost effectiveness. The ADWS is a critical component of the Automated Weather Network (AWN) which is a world-wide network for the real-time collection and dissemination of enviromental and meteorological data and Notice to Airmen (NOTAM) information to support flying operatinal/safety and mission planning by the Department of Defense (DOD). The primary purpose of the AWN is to relay weather data from Europe and Asia via high speed circuits. At the core of AWN are three prime communications nodes which are referred to as the ADWS. The Contractor shall be required to maintain all three ADWSs which are located at Tinker AFB, OK, Hickam AFB, HI and RAF Croughton, UK. The CFEP is a computer system that accomplishes several communications functions for Air Force Global Weather Central (AFGWC) which is located at Offutt AFB, NE. These functions include communications processing for the AFGWC Weather Information Processing System (WIPS) and switching for weather facsimile products, Automatic Digital Network (AUTODIN) messages, the Satellite Data Handling System (SDHS), and the Automated Weather Distribution System (AWDS). The CFEP will also support future communications processing requirements of the AFGWC. The ADWS resides on Unisys 1100/72s mainframe computer systems arranged in a dual configuration (one on-line and one off-line) at RAF Croughton UK and Hickam AFB HI. The Tinker AFB, OK ADWS site resides on Unisys 1100/74 mainframe computer systems also arranged in a dual configuration (one on-line and one off-line). Each mainframe computer system consists of the processors, peripheral equipment, and Distributed Communications Processor (DCP). Automated Weather Distribution System (AWDS) medium speed format/class (modified ADCCP) and X.25 high speed format/class (CCITT 1988 X.25) communications circuits are connected to a dedicated line module per circuit on the DCP. Low speed (TTY) and Meteorological Data System (BEDS) circuits are connected to one indicator (GCS card) per circuit on the GCS. CAT8/VCAT high speed format/class (FAA designed) circuit terminates in an ISO GCS board. The host processor supports the CIDE protocol, IP, TCP, FTP, and SMTP. Protocols supported by the line modules and IOP include UNISCOPE, UDLC, NTR, DDN standard X.25, X.25, AWDS and TTY. The CFEP software currently resides on two Unisys 2200/443s mainframe computer systems arranged in a dual configuration (one on-line and one off-line) at Offutt AFB, NE. Each mainframe computer system consists of the processors, peripheral equipment, and Distributed Communications Processors (DCP). The software required to maintain the integrity of the system is proprietary Unisys 2200 system software. The CFEP runs Unisys EXEC 42R5 operating system software; however, several routines are in either FORTRAN or Meta Assembler language (MASM). (0171)
