Configuring the T1 Buildout
A T1 interface has five possible setting ranges for the T1 line buildout: 0-132, 133-265, 266-398, 399-531, or 532-655 feet. By default, the T1 interface uses the shortest setting (0-132).
To have the interface drive a line at one of the longer distance ranges, include the buildout statement with the appropriate value at the [edit interfaces interface-name t1-options] hierarchy level:
[edit interfaces interface-name t1-options]buildout value;
