Specification for putting RS-422 electrical connections into DB37 connectors. 5000' limit.
EIA specification for general-purpose, 37-position, and 9-position interface for Data Terminal Equipment (DTE) and Data Circuit-terminating Equipment (DCE) employing serial binary data interchange. RS-449-1 includes Addendum 1. Now known as EIA/TIA-449.
Popular physical layer interface. Now known as EIA/TIA-449. See EIA/TIA-449.
Standard defined by EIA, aka. EIA-449. Deals with general-purpose 37- and 9-position interface for data terminal equipment and data circuit-terminating equipment employing serial binary data interchange.
Transmission interface between the codec and the transmission link that typically connects to a t1 Multiplexer. A user RS-449 port may also be available for data transfer.
The Electronic Industries Association (EIA) 37-pin standard for higher-speed (up to 2 Mb/s) serial binary data interchange using synchronous data-link lines.
An EIA standard for a 37-pin data communications connector, usually used with RS-422 or RS-423 electrical specifications. ()
The physical connection for RS449 is generally a DB37. RS-530 The physical connector use for RS530 is generally a DB25. This superseded the RS-449. The RS-530 is a balanced interface that was designed to replace the more expensive V.35 connector.
7EIA standard for serial interfaces.
An EIA specification for general-purpose, 37-position and 9-position interface for DTE and DCE, employing serial binary data interchange and operating at speeds up to 2Mbps.
The RS-449 specifiecs the functional and mechanical characteristics of the interface between data terminal equipment and data communications equipment. The electrical signalling standards intended for use with RS 449 are RS-422 for balanced signals, and RS-423 for the unbalanced signals, with data rates to 2,000,000 bits per second. The standard specified two D-subminiature connectors with 37 and 9 pins for the primary and secondary data circuits.
