1. GENERAL

This practice serves as an Installation and
Maintenance guide for the ADTRAN Total Access
1500 Fractional T1 Data Port (Total Access 1500 FT1
DP). Figure 1 is an illustration of the ADTRAN
Total Access 1500 FT1 DP, (P/N 1180405L1).
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.
