Introduction
This document provides the technical and cable specifications for the EIA/TIA−449 serial cables.
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.
Conventions
For more information on document conventions, see the Cisco Technical Tips Conventions.
EIA/TIA−449 Speed and Distance Limitations
The use of balanced drivers allows EIA/TIA−449 signals to travel greater distances than the EIA/TIA−232
standard. The table below lists the standard relationship between baud rate and maximum distance for
EIA/TIA−449 signals. These limits are also valid for V.35 and X.21.
Data Rate (Baud)
Distance (Feet)
Distance (Meters)
2400
4,100
1,250
