Performance Monitoring
7
From any unit in a system, HDSL performance data may be accessed for each
HDSL span in the circuit, including up to two HDSL doublers (three total HDSL
spans). Access to all PM data is through the faceplate RS-232 port only. Any unit
provides access to the following:
■
HDSL Span Current Status:
■
Alarms
■
Loopbacks
■
Margins
■
HDSL Pulse Attenuation
■
HDSL clock offset (PPM)
■
24-hour HDSL Errored Seconds
■
24-hour HDSL Unavailable Seconds.
■
HDSL Span History:
■
15-min, 24-hour, 7-day HDSL Errored Seconds
■
15-min, 24-hour, 7-day HDSL Unavailable Seconds.
■
HDSL Alarm History
