Press "Z" to zero registers, "X" to restart MIN/MAX, "M" for Main Menu,
Type the letter " " at the Current System Status screen or the Performance History screen in
Z
order to reset the current performance 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 9 and 10 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 DDM+ 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).
