60 -- PROVIDE CAPABILITY TO REMOTE ALL OF THE USER INTERFACES ON INMARSAT B SATELLITE TERMINAL VIA FIBER OPTIC CABLE SOL CC-0720-99 DUE 072599 POC Cathy Carey, 702 295-0205 E-MAIL: Cathy Carey, careyca@nv.doe.gov. 1. The requirement for this product is to provide the capability to remote all of the user interfaces on the INMARSAT B Satellite terminal via fiber optic cable. The make and model is the California Microwave INMARSAT B LYNXX, fixed and transportable systems. The user interface ports RJ-45 Master Handset, RJ-11 Standard Phone Port, RJ11 Fax Port, RS449 (DB37 Pin) and RS232 (DB25 Pin). These interfaces must perform to the specification set forth and approved by California Microwave and AOS Inc (an approved vendor for the INMARSAT B). The solution should provide full capability to remotely control all functions as they appear at the terminal. The requirement is to be able to extend all interfaces and function up to 1000 feet on a single pair fiber optic cable (multi mode on 62.5-micron fiber). 62.5 is the preferred cable as it is in the existing cable plant. 50 micron is acceptable as a secondary solution but would incur additional expense in cable plant upgrade. In addition unit size is critical and theoverall footprint should be as small and lightweight as possible to meet requirements set forth for Emergency Response Systems by the Department of Energy. 2. For more detailed information, contact Cathy Carey at 702 295-0205 or fax your request to 702 295-2088. Posted 07/20/99 (W-SN356761). (0201)
