Part Number: MCR-1153030

Microcom DeskPorte Fast+ External Analog Modem. Features V.34 28.8Kbs Data Rates, Two-Wire and 2/4 Wire Leased Line Transmission, 300Kbs Throughput Rate with Advanced Parallel Technology, V.42, V.42bis and MNP 10 Error Correction. Plug-and-Play Compliant with 14.4Kbs Group III Fax, Standard Serial Interface and Flash Memory for Easy Upgradeability.


The DeskPorte (TM) FAST and DeskPorte FAST+ modem series are Microcom's most fully featured 28,800 bps desktop modems for dial line as well as leased line applications. V.34 technology enables both modems to transmit data at 28,800 bps and achieve throughput rates to 300,000 bps with V.42bis and MNP 5 data compression. At twice the speed of 14.4 modems, the DeskPorte FAST and DeskPorte FAST+ cut file transfer time in half, improve response time on interactive applications and create a more productive environment for remote users.

The DeskPorte FAST and DeskPorte FAST+ are compliant with the new ITU-T V.34 standard. This standard makes communications possible at data rates of 28,800 bps with throughput rates of 115,200 bps using V.42bis data compression.

Other advantages of V.34:

  1. Quick connections are achieved by using the V.8 start-up sequence, reducing the average time needed to establish a connection by up to two-thirds.
  2. Highest possible connection speeds are guaranteed with advanced techniques such as sophisticated line probing, 4D (four dimensional) trellis encoding and shell mapping.
  3. Rate renegotiations take place in less than one second by using Signal S, adapting the connection speed to match fluctuating line conditions.
  4. Data rates from 28,800 down to 2400 bps allow the modem to continue to use the V.34 modulation at all connection speeds, increasing reliability under poor line conditions.

THE PARALLEL PORT SOLUTION
Microcom is the first modem manufacturer to offer the parallel port interface solution.

The DeskPorte FAST modem series supports the standard serial port interface as well as Microcom's revolutionary parallel port interface. Parallel port operations utilize Microcom Windows drivers (included with each modem) loaded on the PC. Users can choose either serial or parallel port operation with minimal set up.

The parallel port interface optimizes the performance of Windows communications applications, where most PC serial ports are limited to throughput rates of 19,200 bps. These PCs can be upgraded to the 16550 UART to support throughputs of 38,400 bps. But to deliver true V.34 throughput, PCs must be retrofitted with high-speed accelerator cards. Therefore, most V.34 modems on the market today have a hidden cost associated with high speeds. And, notebook computers cannot be retrofitted at all!

Microcom's parallel port drivers reroute the data stream through the PC's high-speed parallel port. The parallel port driver is designed to support all third party Windows communications products, including Carbon Copy (TM), CrossTalk, pcAnywhere, Procomm, WinFax Pro, FaxWorks and others. As a result, the DeskPorte FAST and DeskPorte FAST+ provide 300,000 bps performance without costly PC serial port retrofits. And you can have 300,000 bps on your notebook computer too!

COMPATIBILITY WITH NON-V.34 MODEMS
The DeskPorte FAST modem series supports data communications with non-V.34 modems, including ITU-T V.32bis, V.32, V.22bis, V.22, V.21, Bell 212A and Bell 103, thus maintaining compatibility with the installed base of lower speed modems. During the initial link negotiation, the modem recognizes the highest modulation speed the non-V.34 modem will allow, and connects at that speed. Microcom's V.34 modems also support Rockwell's V.Fast Class (V.FC) technology. This enables Microcom's V.34 modems to maintain backwards compatibility with the large installed base of V.FC modems, many of which may not be upgraded to V.34. In addition, if the user has remote as well as central site 28,800 bps modems, it is only necessary to upgrade the central site modems to V.34 to ensure compatibility.

The DeskPorte FAST modem series supports MNP 10 (Microcom Networking Protocol Class 10), the de facto standard protocol for high-performance data communications. MNP 10 allows modem users to get connected, stay connected and achieve the highest throughput rates under all line conditions, including noisy land lines as well as cellular links. First, MNP 10 ensures a dialup connection is established even under the harshest transmission conditions. Second, MNP 10 automatically adapts data packet size and modem transmission speed in response to prevailing line conditions. By continuously optimizing throughput, MNP 10 reduces connect time, resulting in substantial telephone savings and increased user productivity.

FLASH MEMORY
Both modems are also designed with flash downloadable memory so software upgrades and enhancements can be downloaded via floppy disk or the Microcom BBS. Flash memory allows users to keep their modems up-to-date and protect their investment without costly hardware upgrades.

LCD DISPLAY INCREASES EASE OF USE
Combined with five front-mounted LEDs, the DeskPorte FAST modem series' LCD provides users with real-time information on modem operations, including Operating Speeds, MNP Operations, Off Hook, Ring, Connection, Fax Operations, Compression Rate, Carrier Detect (CD), Data Terminal Ready (DTR), Transmit Data (TXD) and Receive Data (RXD).

SECURITY FEATURES
The DeskPorte FAST modem series features two layers of security to help protect PC and network resources from unauthorized access:

Dial Access Security offers three types of security: pass through, fixed callback and/or variable callback. Upon connection, the caller is prompted for a valid user ID and password. If a match is found in the Dial Access Security database, the caller is either passed through for immediate access, called back at a fixed location, or called back at the number requested. This feature provides a built-in security database for up to 40 users.

Enhanced Password Connection Security (PCS(TM)) allows up to 50 encrypted passwords to be stored in the modem. Any one of the 50 passwords can then be verified at link negotiation, providing link security for the network manager and seamless operation for the user.

REMOTE CONFIGURATION
The DeskPorte FAST modem series allows you to change the security levels, password profiles or configurations of the modems from a distance and through any other modem. This allows a central site manager to change remote users' modem configurations without having the modems returned or making time-consuming field support calls. Configurations are password protected to prevent tampering.

V.25bis
Both modems support synchronous and asynchronous ITU-T V.25bis for special host dialing/response applications.

AUTO-LOGON
The modems also offer a flexible scripting language which allows you to customize and automate security logon procedures, enhancing ease of use, flexibility and convenience for the remote user.

UUCP AND KERMIT SPOOFING
The DeskPorte FAST modem series increase throughputs when operating in UNIX and when performing Kermit file transfers by optimizing protocol handling during a call.

AUTOMATIC REDIAL ON LOSS OF CARRIER
Both modems automatically redial and restore a dial connection lost due to poor phone conditions, eliminating the need to restart an aborted file transfer.

Additional DeskPorte FAST+ Features:

LEASED LINE
While both modems support two-wire leased line operations, the DeskPorte FAST+ also supports-four wire leased line applications with two-wire dial backup capabilities. If the leased line no longer supports data communications, the modem will automatically switch to the two-wire dial backup line. This automatic dial backup capability provides fail-safe connections for crucial data transfers, including mission-critical and real-time applications.

AUTOMATIC LEASED LINE RESTORAL
In the event the leased line does fail and the dial backup line is in use, the modem will periodically sample the leased line to determine whether it has returned to a state sufficient for data transfer. Once conditions have improved enough to drop the dial backup connection, the DeskPorte FAST+ will automatically restore leased line communications so that the user is not paying for two connections longer than necessary.

WHY THE DESKPORTE FAST?
With the DeskPorte FAST modem series, we are combining Microcom's 12 years of data communications experience and latest technology to provide you with the fastest speeds and most reliable connectivity at the lowest cost. With V.34 speeds and MNP 10 reliability, the DeskPorte FAST and DeskPorte FAST+ place users into a more productive environment while cutting annual dial charges. With the parallel port interface, both modems provide 300,000 bps in a Windows communications environment without the hidden costs associated with upgrading PCs.
