Field

Description

 

 

 

Circuit Configuration

 

 

G.703

Indicates the interface standard for G.703 data port.

n TS

Indicates the number of time slots (n) mapped to the G.703 interface.

Timing

Indicates the primary source the unit uses for clock synchronization:

EXT

External 2.048 MHz clock.

G.703

G.703 port receive clock.

Application mode

Indicates that the Single Pair (SINGLE) application mode is in effect.

 

 

 

Performance

 

 

MAR1

Displays the Margin value for each HDSL interface or displays link status (SIG, ACQ, etc.) if the link

 

is not up.

MAR2

Reserved

 

 

ES1

Displays the Errored Seconds (ES) counts for each HDSL interface. The counts are for the latest

 

24-hour period, calculated as the sum of the counts in the previous 95 15-minute intervals, plus

 

the count in the current 15-minute interval.

ES2

Reserved

 

 

 

Alarms

The Alarms field displays a list of all active alarms at each LTU/NTU and HDSL interface.

 

 

 

Possible LTU/NTU Interface Alarms

 

 

Loss of Signal (LOS)

Loss of signal at the G.703 input.

Loss of Frame Alignment (LFA)

Loss of frame alignment at the G.703 input.

Receive Alarm Indication

Alarm indication signal (unframed all ones) received at the G.703 input.

Signal (AIS)

 

Remote Alarm Indication

Remote alarm indication signal received at the G.703 input (through A-bit).

Signal (RAI)

 

Loss of Clock (LOC)

Applies to loss of external clock when EXT timing is used. The external clock was lost for the

 

previous second. This alarm is reset when the clock is active again.

 

 

 

Possible HDSL alarms

 

 

Margin (MAR)

Margin has fallen below threshold set for the HDSL interface.

Errored Seconds (ES)

Errored seconds count has exceeded threshold set for the HDSL interface.

Loss of Sync Word (LOSW)

Loss of sync word at the HDSL interface. Remains active during restart, but not a cold start.
