1. GENERAL

This practice provides installation and maintenance

procedures for the ADTRAN Single-Wide

Fractional T1 (FT1) Repeater, (ADTRAN P/N

1245211L1), illustrated in Figure 1.

The ADTRAN Single-Wide FT1 Repeater is a

device used to extend the effective range of an

ADTRAN FT1 circuit. It is capable of doubling the

deployment range of standard HDSL, providing a

carrier service area (CSA) compliant loop on both

sides of the Single-Wide FT1 Repeater.

Features of the Single-Wide FT1 Repeater include:

• 2B1Q line coding

• Range up to 12 kft of 24-gauge wire each direction

from FT1 Repeater

• Lightning protection

• Remote loopback control

• Coexists with DDS and ISDN repeaters in same

apparatus case

• Remote performance monitoring capability

This unit is used in conjunction with any span

powering FT1 DP for the central office and span

powered FNID remote end as follows:

Part Number Unit Name

1245207L1 ........... Northern Telecom FT1 DP

1245208L1 ........... ALCATEL FT1 DP

1245205L1 ........... WECO D4 FT1 DP

1242040L2 ........... AT&T FT1 DP

1242041L2 ........... FNID (T400)

1242042L2 ........... FNID (standalone)

The ADTRAN Single-Wide FT1 Repeater provides

a means of extending the digital subscriber loop

serving range using a centrally-located unit. There

are no manual option settings on the Single-Wide

FT1 Repeater.
