The Following Speed Information Covers various Electronic Mailbox Systems for Transferring Large CAD, Graphic Files and Other Bulk Data

CTI's most popular modem package for Dial-Up 3780 BSC File Transfers is the SyncPack2000e


Several large Tier I suppliers  are using various CTI dial-up file transfer programs to OEMs and other suppliers. CTI’s latest TCP/IP Intranet oriented mailbox system generates considerable speed (throughput) improvements over other linkages.

The graph below shows speed advantages using CTI’s latest high-speed, TCP/IP bulk data mailbox solution versus other mailboxes using IBM 3780 oriented packages. This graph displays typical actual time to send a 1.0 megabyte compressed CATIA binary CAD file into various locations including the Chrysler CTX Mainframe system (top bar), and Toyota’s 3780 Mailbox Server system (2nd bar from top) versus sending the same file into CTI’s central Mailbox Server (bottom bar) using TCP/IP. The other bars within the graph are for reference purposes only. These speeds reflect dial-up file transfers - NOT transfer times over a LAN or WAN...

New Speed Record - Fastest to Date

In September, 1998 one of the Internet Service Providers in the Detroit area who specializes in high-speed file transfers began speed tests downloading large graphics files over a (10Mbps) wireless connection using CTI's managed TCP/IP Store-and-Forward Mailbox System

The ISP, Speedchoice, was able to download a 44.5 MB file in just 85 seconds (this is over 31 megabytes per minute).  Is this fast enough for you?  For companies which need to transfer truly large files and maintain management control, this appears to be the way to go.

At these high-speeds it would hardly even measure on the graph to the left. 

If a company’s future traffic volume is anticipated to increase, then the TCP/IP oriented mailbox system may be the best choice - especially since it operates over standard telephone lines and does not require suppliers to purchase special synchronous software and related hardware.

Special Note:  CTI's TCP/IP based Store-and-Forward Mailbox System also supports MLPPP (MultiLink Point-to-Point Protocol) that allows for even faster data throughput by bonding more than one modem (or ISDN BRI Terminal Adapter) together to form a single faster link, however, this protocol speed improvement is not reflected in the above chart.

What does all this mean? Actual data throughput, not the speed of a modem and not necessarily the use of a special class of telephone line (like digital ISDN), is what really counts in compressing time to market. CTI’s software and related V.34 business modems can provide the speed you need. CTI’s latest Windows based, TCP/IP Mailbox Package has been designed “from the ground, up” and is not a collection of miscellaneous industry software packages assembled together for a quick Netscape internet browser system with limited speed and throughput potential. CTI’s 32 bit Windows version is providing the fastest known communications packages for moving critical data over standard low cost analog telephone lines (although not limited to analog lines). Hayes has done some interesting things in terms of data compression with their 8:1 compression capabilities.

A company sending and receiving data from divisions, customers and suppliers will benefit from the speed of CTI’s TCP/IP mailbox system. This graph will be up-dated when additional data becomes available. Please telephone CTI with any questions.
