58 -- COAST GUARD DATA NETWORK EQUIPMENT POC Contact: Contracting Officer: LCDR George Asseng, Ph: 202/267-6206 The Coast Guard intends to procure, on a sole source basis, hardware to update the Coast Guard Data Network (CGDN). The CGDN is a ''private'' packet switching network based on the X.25 protocol standard. The equipment used in the CGDN consists of Sprint Transport Protocol 3 (TP3) concentrators and TP4 series packet switches owned by the Coast Guard. Sprint TP equipment is the only known equipment compatible with the existing CGDN TP software and is believed to be the only reasonable and cost effective solution. The only alternative is to completely redesign the existing network with new equipment. The proposed Indefinite Delivery/Indefinite Quantity contract would be for the following minimum quantities: (20) HSLPU-405 cards - this card is an X.25 port card for the Sprint TP4855 and TP4228 switches; (3) APB Cards for the TP3325 - this card is a 4 port protocol card for the TP3325 concentrators. The APB is a packet assembler/disassembler (PAD) that encapsulates SNA, Async, 3270 and 3780 protocols for X.25 transmission; (3) AEB Cards - this card is a 4 port extender used in conjunction with the APB card in the TP3325 concentrator; (3) XEB Cards - this card is an X.25 extender card that provides 4 ports in the TP3325 concentrator; (12) TP3025 X.25 concentrators - this concentrator expands one X.25 circuit into 8 circuits.Other firms who can furnish this equipment are invited to submit clear and convincing data substantiating their capability to furnish the entire requirement. Vendors failing to provide complete information for an accurate comparison will not be considered. Responses shall be addressed to the following: Commandant (G-ACS-1A/GA), U. S. Coast Guard, 2100 Second Street, S.W. Washington, D.C. 20593-0001. Fax responses should be submitted to (202) 267-4018. All responses must be in writing. See Numbered Note 22. (0139)
