I have a hayes V series 9600 internal modem which uses a proprietary method of sending at 9600. Can I upgrade this to the current standard? Is the current v.32, and how long would people think that this will remain the standard? Thanks in advance. John M Vinopal banshee@ucscf.UCSC.EDU ucbvax!ucscc!ucscf!banshee

- I have a hayes V series 9600 internal modem which uses a - proprietary method of sending at 9600. Can I upgrade this - to the current standard? Is the current v.32, and how long - would people think that this will remain the standard? V.32 is the one and only international standard for full-duplex transmission at 9600bps on two-wire dial-up telephone circuits. It has existed since 1984, but it is only recently that advancement in modem technology has allowed them to be offered at prices within the range of acceptability for most users. However, high user demand for throughput above 2400bps led modem manufacturers to develop proprietary schemes for higher-speed transmission. Several different and incompatible schemes resulted, including the Fast Turnaround Ping-Pong technique used in the V-series 9600 from Hayes, PEP from Telebit, HST from USRobotics, MNP6 from Microcom, and many others. Virtually all of these manufacturers have either delivered or announced products that include real CCITT V.32, usually along with backward compatibility with their proprietary schemes. Hayes is among those having announced such a product -- the V-series ULTRA Smartmodem 9600. ULTRA 96 has all of the features of the V-series Smartmodem 9600 V.42, including V.42bis data compression and MNP5, plus V.32 modulation, X.25 packet-network connections, and many other advanced features. The list price will be $1,199, and it is scheduled to ship within the next month or so. To directly answer your questions: no, Hayes has not announced an upgrade program from VSM9600 to ULTRA 96. The technology is completely different, and about the only thing the two modems have in common is the metal cabinet and black plastic "nose cones" -- and the little rubber feet; the innards are completely new in Ultra 96. With regard to the longevity of V.32 as a standard: I am Hayes' representative to the CCITT, and can assure you that V.32 is NOT going to be displaced as the standard for 9600bps communications any time soon (meaning, probably not ever). However, the CCITT is working on a new standard V.32bis which will include operation at 12000 and 14400 bps; this will probably be finalized within the next couple of years, maybe by the end of 1990 if we can resolve a couple of technical points in dispute between the US and the UK. We just finished a meeting of the technical subcommittee working on the issue (hosted by Hayes here in Atlanta), and reached substantial agreement on many of the issues; the next meeting is in April in Geneva. I hope I've been able to be helpful. -- Toby Nixon, Principal Engineer, Hayes Microcomputer Products Fax: +1-404-441-1213 Telex: 6502670805 Phone: +1-404-449-8791 Compuserve: 70271,404 MCI MAIL: TNIXON (267-0805) AT&T Mail: !tnixon Telemail: T.NIXON/HAYES Genie: TOBY.NIXON BBS: 1-800-US-HAYES FidoNet: 1:133/301 X.400: C=US / AD=ATTMAIL / PN=TOBY_L_NIXON / DD=TNIXON UUCP: ...!uunet!attmail!tnixon Internet: 70271.404@compuserve.com

I have a pair of Hayes Smartmodem-9600 (V.42) modems and want to know
if they can be upgraded.
