1. LOSS is typically several dB less than the insertion loss measured at 200 kHz.
The LOSS measurement is a better indication of the loop's attenuation of the
2B1Q signal than the insertion loss measured at a single frequency. ADTRAN
HDSL can operate on cables with an excess of 30 dB LOSS.
2. The first number is for the current 15-minute period and the second is the cur-
rent 24-hour period (Loop 1 and Loop 2 numbers are displayed).
An indication of Pair Reversal (if present) appears at the bottom of the first key column. Definitions
for this key are provided in
DSX-1 signals is located in the center of the screen near the bottom.
