Claim:
A system for modifying an existing HDSL chassis comprising: a cable harness comprising: a plurality of data lines; connectors connecting said plurality of data lines to craft access ports of an existing HDSL chassis such that each craft access port has a dedicated data line; and a harness bar assembly comprising: a protective channel for housing said cable harness, at least one locking arm extending from the protective channel, the locking arm including an oblong slot that allows movement of the harness bar assembly relative to the existing HDSL chassis, and a multiplexer formed unitarily with the harness bar assembly, wherein said harness bar assembly locks into a resting position so as not to obstruct access to equipment adjacent to said HDSL chassis, and wherein said harness bar assembly can be unlocked and moved to a retracted position sliding along the oblong slot so as to be temporarily displaced, thereby allowing removal or installation of one of said HDSL circuit cards without disturbing any other of said data line connections.
