ACTION: Notice. ----------------------------------------------------------------------- SUMMARY: This announcement serves as notice that the Internal Revenue Service plans to discontinue the use of the bisynchronous communication protocol for IRS e-filing of Forms 1040 series, including the stand- alone Electronic Tax Document System. This includes Forms 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return and Form 9465, Installment Agreement Request. DATES: The effective date for this discontinuation is October 18, 1999 at the conclusion of the 1999 filing season. ADDRESSES: Questions or concerns should be directed to Carolyn E. Davis, Senior Program Analyst at IRS, Electronic Tax Administration, OP:ETA:O:S, 5000 Ellin Road C4-187, Lanham, MD 20706. FOR FURTHER INFORMATION CONTACT: Questions or concerns will also be taken over the telephone. Call 202-283-0589 (not a toll-free number) or via email to: carolyn.e.davis@m1.irs.gov. SUPPLEMENTARY INFORMATION: If transmitters are using the XMODEM, YMODEM, or ZMODEM file transfer protocols, they are using asynchronous and not bisynchronous protocol, and therefore are not affected by this notice. In addition to offering asynchronous connectivity, the IRS also is capable of receiving data via TCP/IP on 56kbs and ISDN lines. Other high-speed alternatives are also being considered. Concurrent with this action, the IBM Series/1 minicomputers will be decommissioned at the same time. All of the above returns/forms will be transmitted to the Austin Service Center in Austin, TX and to the Tennessee Computing Center in Memphis, TN for the 2000 e-file season. Approved: Carol Stender-Larkin, Acting National Director, Electronic Program Operations, Electronic Tax Administration. [FR Doc. 99-15571 Filed 6-18-99; 8:45 am] BILLING CODE 4830-01-P
