Configuring the T3 Line Buildout

 

A T3 interface has two settings for the T3 line buildout: a short setting, which is less than 255 feet (about 68 meters), and a long setting, which is greater than 255 feet and less than 450 feet (about 137 meters). By default, the interface uses the short setting.

The long-buildout and no-long-buildout statements apply only to copper-cable-based T3 interfaces. You cannot configure a line buildout for a DS3 channel on a channelized OC12 interface, which runs over fiber-optic cable. If you configure this statement on a channelized OC12 interface, it is ignored.

To have the interface drive a line that is longer than 255 feet and shorter than 450 feet, include the long-buildout statement at the [edit interfaces interface-name t3-options] hierarchy level:

To explicitly configure the default short line buildout, include the no-long-buildout statement at the [edit interfaces interface-name t3-options] hierarchy level:
