Revision History

This is the initial release of this document.  Future
revisions to this document will be explained in this
subsection.

Description

The Total Access 1500 FT1 DP is the Central Office
unit used to deploy an FT1 circuit using 2-wire
metallic facilities.  The Total Access 1500 FT1 DP
plugs directly into a standard Total Access 1500
channel bank.  Signals are provided to and from the
channel bank while 2B1Q HDSL signals are provided
to the local loop.
