58 -- VHF-FM RADIO DIRECTION FINDING SYSTEMS SOL DTCG89-00-Q-65D001 DUE 020400 POC Contact Robert Townsend, Contracting Officer 510/437-3009 E-MAIL: click here to contact the Contracting Officer via, rtownsend@d11.uscg.mil. This notice is to provide answers to vendor questions about Request For Quotations DTCG89-00-Q-65D001. The due date for quotes of 04 February 2000 is unchanged. Question 1: Is the multiplexed data coming from the various remote location available into 1 physical interface and somehow tagged by means provided by the vendor or the CG (as it could be expected in 'CAN over WAN' environment)? Answer 1: No. Serial data streams from remote sites are sent through CG telecomms system and then multiplexed into 1 physical interface provided by the vendor into the PC at the OPCEN. Question 2: Is it available in the form of multiple RS-232C ports present at some CG provided device (one port by remote location) in such fashion that will require a multiple serial port intelligent controller in the PC (i.e. Digi International Intelligent Multiport Controller)? Answer 2: See answer to Question 1. Question 3: Is it time de-multiplexed using a standard Telco strategy, such as the many devised to convert a T1 (or fractional T1) into up to 24 usable data and/or voice channels? Answer 3: No. See answer to Question 1. Question 4: Is it a multipoint X.25 based approach? Answer 4: No. Question 5: If any or none of the above apply, can the vendor suggest (software and maybe hardware) approaches which will enhance the response time of the overall system, increase the through output, and minimize the 'network' latency, without any cost increase? Answer 5: No. Must meet minimum requirements. Question 6: Could it be of interest to the CG, to design the overall system to be able to use RS-232C now, and TCP/IP in the future while maintaining backward compatibility, so it could be designed that way at once, making future major changes in form, fit, or function, unnecessary? Answer 6: No. Must meet minimum requirements. Posted 01/31/00 (W-SN420392). (0031)
