70 -- REMOTE LAN ACCESS EQUIPMENT AND MAINTENANCE POC Patricia H. Drew tel: (410) 966-1325 The Social Security Administration (SSA) has a requirement to purchase equipment allowing high performance LAN connectivity to SSA's data network for Remote dial-in users using IBM compatible, notebook personal computers, and/or personal computers through the circuit switched public and FTS-2000 network. This access must be provided as seamlessly and transparent to the user as possible by connecting to SSA provided, 16/4 Megabit per second, Novell Token Ring 802.5 based Local Area Networks (LAN). SSA is planning the installation of communications server(s) having a capacity of 96 ports (Year 1) and a quantity of 1-96 in years 2 and 3) at each of SSA's Nodes. The Node's are located at Baltimore, MD, Philadelphia, PA, Kansas City, MO, Birmingham, Al, New York, NY, Richmond, CA, and Chicago, IL. These networks currently run traditional LAN applications, 3270 Host applications, CD ROM based document image retrieval applications and LAN server based, graphical user interface (GUI) applications. SSA users on the LAN currently have multi-session access to all LAN and 3270 applications (five simultaneous sessions per user). SSA desires near real time service to the remote user for all applications currently supported in a manner as equivalent as possible to local LAN access today. The network, including the LAN, is managed via Netview and all terminals remotely connected must appear to Netview as individual local users. Users typically use Dynacom/Elite, Attachmate or PC3270 terminal emulation software, (Vendor must specify which 3270 emulator software works with their product) in LAN connected PCs to access 3270 Host based applications, through 3745 communications processors. SSA will use notebook PCs that operate in a Microsoft Windows 3.1, OS/2 or Windows NT environment. Since real time applications will be supported, SSA envisions support for at leaast 14.4 Kbps Modems, Auto Baud capability, and encourages compression for speeds of 38.7 Kbps and above. Operational compatibility shall be demonstrated using internal modems contained within notebook compatible PCs. Server modems shall be housed in 19'' racks. The Remote LAN Server shall also have the capability of providing either switched 56 or ISDN support. SSA may employ ISDN terminal adaptor based modem pooling through the SSA telephone system, when such service is available to eliminate the need for separate trunk groups, ports or servers for simultaneous user transparent analog and ISDN support. SSA desires remote access to its current architecture through Remote Node technology. SSA currently accomplishes data access security via: 1. A separate dial-up access control consisting of user identification and password; 2. Host site call-back to a pre-determined remote site telephone number, with control of the call-back number technically restricted to the host site; This option shall have the option of being selected or de-selected by SSA. 3. Data Encryption shall be incorporated in positively identifying the dial-in terminal to the host port. These security capabilities shall be provided in addition to other SSA provided LAN security for local users. SSA requires security capabilities which meet or exceed our current level of security but desires information regarding new more advanced approaches of meeting our access security requirements. For example SSA is interested in security via secured single logon. Organizations which manufacture or distribute remote LAN access equipment as described herein are invited to submit complete information including descriptive literature on all required hardware and software, a connectivity block diagram, and any unusual operational or installation requirements within 15 days after this publication. Also, identify and submit the names, addresses, and telephone numbers of three (3) of your Customer accounts which have integrated and installed the above in a normal production environment (i.e., not a test site). An indefinite quantity contract with a systems life of 7 years is planned. No award will be made on the basis of this synopsis. Requests for copies of a solicitation will not be honored. The Government does not intend to pay for information received in response hereto. (0116)
