The Current System Status screen, illustrated in
Figure 7, provides quick access to status information
for both the FT1-DP and FNID. The Elapsed Time
display indicates the period of time since the unit
began collecting performance information.
Current information for the DSL and DS1 interfaces is
consolidated on this screen. A key to the information
provided is found in the center of the screen. Arrows
indicate the key applies to both the FT1 DP and FNID.
LOSS ........................ Pulse Attenuation Measurement
SYNC ....................... HDSL Loop 1 Sync Status
ES 15M/24H ............ Errored Seconds
SES 15M/24H .......... Severely Errored Seconds
UAS 15M/24H ......... Unavailable Seconds
For example: ES 012/264 indicates that 12 errored
seconds have occurred in the current 15-minute period
while a total of 264 errored seconds have occurred in
the last 24 hours.
