time, then TUC displays. The single x

 

 

 

indicates Loop 1 or Loop 2.

xxxx-LAx (d)

Loop Attenuation

The attenuation on the HDSL4 loop has

HDSL4 loop attenuation threshold.

 

xxxxdenotes TUC, TUR, or first (DU1U/DU1D) or second (DU2U/DU2D) doubler HDSL4 upstream or downstream interface. If TUC and TUR occur at the same time, then TUC displays. The single x indicates Loop 1 or Loop 2.

(a)The message, ALRM, displays prior to any alarm message.

(b)Message displays repeatedly as long as the alarm condition exists and is not included in the priority order.

(c)When the HDSL4 loop loses sync word (LOSW), a system alarm condition exists. However, since the H4TU-C-319 enters the acquiring mode, the front-panel status LED flashes red, and the ACQ or SIG message displays instead of the ALRM message.

(d)Only these alarms assert the System Alarm bus on pin H of the card-edge connector, if the ALM option is set to enabled.
