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.
