Fields in Main Console Screen
Field
Description
Circuit Configuration
V.35/V.36/X.21/RS-530
Indicates the interface standard for Nx64k serial data port.
n
k
Indicates the data rate (
n
) mapped to the Nx64k interface.
Timing
Indicates the primary source the LTU/NTU uses for clock synchronization:
INT
Internal oscillator.
EXT
External 2.048 MHz.
Nx64k
Serial data port receive clock.
HDSL
Recovered clock from received HDSL data.
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
second counts for each HDSL interfaces. 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 Nx64k port alarms
LOC
Loss of incoming clock (TT) at the serial data port (only enabled if the primary timing source is
Nx64k).
Possible External Clock Alarms
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
MAR1
Margin threshold has fallen below alarm threshold for the HDSL interface.
ES1
Errored second count has exceeded alarm threshold for the HDSL interface.
LOSW1
Loss of sync word for the HDSL interface. Remains active during restart, but not a cold start.
