Equipment interface reference points

The various pieces of equipment connected to the BRI
and PRI have their own interface classifications. The
interfaces between a Terminal Equipment (TE) and a
Local Exchange (LE), or Central Office (CO) are
conceptually known as the 'R', 'S', 'T' and 'U' interface
reference points.
The conceptual interface reference points are shown in
the following illustration.
