2. INSTALLATION With the exception of the physical dimensions of the units, the FNID and T200 FNID units are functionally identical. The FNID terminates local loop DSL signals originating from the Central Office (CO) unit and transforms the DSL signal into fractional T1 C A U T I O N ! signals to be delivered to the customer. SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY. HANDLING PRECAUTIONS REQUIRED. The DSL local loop operates over a single twisted pair. The FNID communicates

A measure of signal quality for each HDSL loop is displayed in graphic form on the bottom right and left of the screen. The measure is from 0 (poor signal quality) to 9 (excellent signal quality). Guidelines for interpreting the indicators are: -7 0 Noise margin is ≤ 0 dB (≈ 10 BER) -7 1-8 Margin measurement above 10 BER in dB -7Ê 9 Margin is ≥ 9 dB (excellent quality) above 10 BER Predicting performance based upon signal quality varies with each loop. Generally, a noise margin of 0 or higher

There is one loopback available to the FT1 Repeaters. loopback is initiated by the DDS latching loopback The FT1 Repeater Network loopback is a digital code for NEI Position 1 (N1000001) for a loopback toward the CO as shown in Figure A-4. The non-repeatered loop, or NEI Position 2 (N1000001) loopbacks are initiated by the DDS latching loopback for a single repeater loop or by NEI Position 3 codes for NEI Position 1 (N1000001) for FT1 #1 or (N1000001) for a two repeater loop; by the craft NEI
