Release Information

Statement introduced before Junos OS Release 7.4.


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

This statement applies to copper-cable-based T3 interfaces only. You cannot configure a line buildout for a DS3 channel on a channelized OC12 interface, which runs over fiber-optic cable.


A T3 interface uses the short line buildout setting (no-long-buildout) for wires shorter than 255 feet (68 meters).
