`Recently someone has mentioned the Telebit T2500 Modem and his functions.
`Is the T2500 already available and how much does it cost?
` Thanx,

`
`n response to many similar requests, I am reposting the T2500 product
`announcement. Note in this announcement, we have also reduced the price
`to $1495 for both standalone and rackmount form factors.
`Telebit has been shipping the T2500 for close to two months. Also, this
`modem will be available through the Internet Discount Program (see posting
`of about 2 weeks ago) for $899 prepaid. I hope this helps to answer questions.

`
`NEW DIAL-UP MODEM FROM TELEBIT OFFERS
`FULL COMPATIBILITY WITH PEP, V.32 AND LOW-SPEED MODEMS
`MOUNTAIN VIEW, Calif.-- February 6, 1989 -- Recognizing the market's
`need for a high-speed modem that is compatible with today's universe of
`dial-up modems, Telebit Corporation today introduced the industry's
`first modem to provide full compatibility with CCITT V.32 and low-speed
`modems as well as multicarrier PEP modems.
`"High-speed connectivity has become critical for the long-term success
`of businesses and institutions of all sizes," said Lewis F. Ellmore,
`Telebit president and chief executive officer. "For this reason,
`organizations worldwide are seeking dial-up communication solutions that
`allow them to transfer data at speeds greater than 9600 bps while
`maintaining compatibility with V.32 modems and the installed base of
`low-speed modems. Telebit's T2500 PEP modem offers these organizations
`the ultimate solution: speed, connectivity and universal compatibility
`in one cost-effective package."
`The T2500 operates in both synchronous and asynchronous environments
`and supports all major modem-industry standards. It communicates with
`other T2500 modems and the installed base of Telebit and other
`multicarrier PEP modems at speeds up to 18,000 bps without data
`compression and up to 19,200 bps with data compression. When
`communicating with V.32 modems, the T2500 supports error-free
`transmission speeds up to 9600 bps with Trellis-Coded Modulation (TCM).
`For organizations with low-speed connectivity needs, the T2500 offers
`downward compatibility with CCITT V.22 bis, V.22, V.23, V.21 and Bell
`212A and 103J modems, at speeds from 300 to 2400 bps.

`
`V.42 compatible, the T2500 supports error correction and data
`compression through MNP Class 5 for speeds of 9600 bps and below. At
`higher speeds, the Telebit modem ensures data integrity with PEP 16-bit
`CRC error-detection and control protocols and delivers data compression
`using a Lempel-Ziv algorithm.
`In addition to providing universal compatibility, the T2500 offers users
`the connectivity benefits of Telebit's patented multicarrier PEP
`technology. Because Telebit's PEP (Packetized Ensemble Protocol)
`technology enables the modem to take advantage of the entire bandwidth
`of the telephone line rather than just one or two frequencies, the T2500
`maintains connections on telephone lines that modems using conventional
`technologies are not able to sustain. The T2500--like all other PEP
`modems--adjusts its transmission speed in 100 bps decrements when faced
`with deteriorating lines, rather than halving its transmission speed as
`do non-PEP modems. As a result, the T2500 delivers throughputs over
`ordinary telephone lines up to six times faster than possible with other
`dial-up modems.
`In asynchronous PEP mode, performance is maximized by providing
`integrated support for UNIX UUCP, Kermit, Xmodem, Ymodem, and SNA/SDLC
`file-transfer protocols.
`With the T2500, users do not need to invest in new data communications
`programs or modify their existing software. The factory default
`Conventional Command Mode allows the T2500 to be configured
`automatically using any software that supports the Hayes V-series
`command set, while Telebit's Enhanced Command Mode allows users to take
`full advantage of the T2500's advanced features, such as remote
`configuration management.
`"The T2500 provides organizations a means to realize the benefits of
`today's technology without putting their communications investment at
`risk," said Ellmore. "Telebit's software-defined architecture allows
`future standards to be incorporated readily.
`"Most important, Telebit's multicarrier technology continues to evolve
`-- users can expect to see further significant performance increases.
`In contrast, conventional, single-carrier technology has reached its
`ceiling for speed."
`The T2500 is available as a standalone unit or as a rackmount system
`card, which can be installed in a Telebit T9000 rackmount system
`chassis. Each chassis holds up to 12 modem cards and mounts into a
`standard 19-inch EIA rack for easy integration with other data
`communications equipment. An intelligent controller card permits local
`or remote configuration, monitoring, control and testing of up to four
`racks (48 modem cards) for system administration at a central site.
`List price for both units is $1695. Availability for the standalone
`model is April 1989 for asynchronous functions and second quarter 1989
`for synchronous functions. Rackmount cards are available third quarter
`1989.
`Upgrades are available for the standalone and rackmount versions of
`Telebit's TrailBlazer Plus, a 19,200 bps asynchronous modem. Also
`available are upgrades for the standalone and rackmount versions of the
`T2000, a high-speed SDLC modem.
`TrailBlazer Plus and T2000 standalone and rackmount card modems
`purchased before January 1, 1989, can be upgraded for $795. Upgrades
`for TrailBlazer Plus and T2000 products purchased after January 1, 1989
`will be available from Telebit for $395. Upgrades must be pre-paid and
`will require return to the factory.
`Additional product information can be obtained by calling 1-800-TELEBIT
`or (415) 969-3800.
`Telebit Corporation, a leader in the high-speed dial-up modem market,
`develops, manufactures and markets advanced high-speed communications
`products for dial-up networking and wide-area digital communications.
`The company's digital signal processing and packet transmission
`technologies allow for the software implementation of widely used
`communications protocols. Telebit markets its product worldwide through
`original equipment manufacturers, value-added resellers, distributors
`and direct sales to major national accounts.
