The ADTRAN FT1 DP occupies one physical channel unit of an AT&T

Network System (WECO ™ ) D4. The ADTRAN FT1 DP works with the ADTRAN

Fractional T1 Network Interface Device (FNID). Together the units support two-way fractional T1 transport at rates of 128, 256, 384, 512, 640, and 768 kbps over an existing CSA loop plant, without loop conditioning or service degradation. The technology used in the FT1 DP is High-bit-rate Digital

Subscriber Line (HDSL). The HDSL transport complies with the specifications contained in Bellcore TA-NWT-0001210, FA-NWT-0001211, and ANSI

T1E1 HDSL Technical Report - TR28.

The FT1 DP can span power the (FNID). In addition, the FT1 DP is capable of span powering a Fractional T1 repeater which can be used to double the deployment range of a circuit. The FT1 DP maintains all provisioning options of the FT1 circuit. These options are set either manually (through

DIP switches) or through a craft access RS-232 interface (DB-9). The FT1 DP also provides extensive Operation, Administration, Maintenance, and

Provisioning (OAM&P) information through faceplate features or the terminal interface.

HDSL local loop operation is independent of the channel bank chosen to deploy the FT1 DP units. The FT1 DP is the master in the master/slave relationship with the FNID. The FT1 DP provides span powering to the

FNID, if required by the application. Additionally, the FT1 DP provisions and maintains the FT1 circuit. Provisionable options may be selected through manual switch selections and through a controlling terminal interface. Once selected, these options can be changed by either of these two methods; the FT1 DP remembers the last change implemented.
