screens at both the HLU-200 List 1D and the HRU-412. The RS-232 terminal interface at the HRU-412 does

not allow the counters to be cleared.

Figures 33 through 35 show the ALARM HISTORY screens for Doubler applications. The alarms are defined

in Paragraph 6.1. The LOS and PWR system alarms are common to all spans. Only the LOSW, ES and

MARGIN are span specific alarms. The PWR-OPEN and PWR-SHRT alarms indicate alarm conditions on the

HLU-200 List 1D. Neither PWR alarm is available on the other spans. In Figures 33 through 35, the "First"

and "Last" columns contain the time and date stamp of the first and last occurrence of each alarm. The

"Current" column shows the status of each alarm. The "Count" column lists the number of times each alarm

occurred. All the data can be cleared by pressing C (Clear). The maximum non-overflowing count is 999. The

SPAN 1 Screen concerns alarms that occurred on the two HDSL loops between the HLU-200 List 1D and the

first Doubler (HDU1). The SPAN 2 Screen refers to the loops between the first Doubler (HDU1) and the HRU-

412 for one-Doubler circuits or between the first and second Doublers (HDU1 and HDU2) for two-Doubler

circuits. The SPAN 3 Screen refers to the loops between the second Doubler and the HRU-412 for two-

Doubler circuits.
