Technical Definitions:  smallredarrow.gif (103 bytes) BSC (Binary Synchronous Communications) protocol using binary data between mainframe computer systems and IBM 2780 and 3780 Remote Job Entry terminals (now used almost exclusively on PCs).  3780 BSC is widely used in many  market niches like: Retail (outlets like Wal-Mart and TARGET); Banking and Credit Unions; Collection Agencies; Electronic Data Interchange (EDI); EC (Electronic commerce), Government IRS (electronic tax filing); credit card verifications; Automotive (CAD file transfers); and other markets.  Data characters are gathered in a package called a frame that is marked by two (bi) start and stop synchronization bits.  It operates with EBCDIC or ASCII character sets.  smallredarrow.gif (103 bytes) Versus Asynchronous Transmission - a method of communications between computers whereby data bytes are separated from each other by preceding each with one or two start bits and following each one with a stop bit.  Bytes may be sent at irregular intervals. (Note - in synchronous transmission, a clock is used instead of start and stop bits).  smallredarrow.gif (103 bytes) RJE (Remote Job Entry) - a method of submitting work to and from a computer (usually a mainframe system) in either a batch "3780" (BSC) or a "3770" (SNA) format.  Though sometimes superseded by the 3270 interactive (versus a Batch) system. 

FastSync® 3780 is available in a configuration that does not require a synchronous hardware device.  Click here to review the SyncPack2000e product.  For all UNIX oriented products, click here.

Software Overview

FastSync 3780 from CTI is a very fast, easy to install, easy to use, powerful, and feature rich 3780/2780 IBM Remote Job Entry (RJE) bisynchronous file transfer program for Micro-to-Mainframe, Mainframe-to-Micro, and PC-to-PC communication applications.

The basic 3780 code was initially developed in the 1970s and has now matured into a true third generation software product. FastSync 3780 was designed for absolutely error free, reliable, maximum high speed data transfers. For a list of program Commands along with a quick overview, click here.  It operates not only over standard analog type Public Switched Telephone Network (PSTN) lines, but also over digital ISDN (Integrated Services Digital Network) Basic Rate Interface (BRI) lines. For an overview on how to functionally use FastSync3780 commands, click here.
