Press "Z" to zero registers, "X" to restart MIN/MAX, "M" for Main Menu,
Type the letter " " at the Current System Status screen in order to reset the current perfor-

mance registers to zero on both the Current System Status and Performance History screens.
A prompt requires user confirmation to execute the zero registers function.
Figures 8 and 9 consolidate current information for the HDSL, DSX-1, and DS1 interfaces. A
key to the information provided is found in the center of the screen and defined in
below. Arrows indicate the key applies to both the 220 HTU-C and HTU-R.

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
current 24-hour period (Loop 1 and Loop 2 numbers are displayed).
