ADTRAN T200 IDSL warranty Latching Loopback Timeout, Loopbacks, OCU-R Network Customer

Figure 13 shows the Loopbacks display, allowing loopback testing to be initiated or terminated while graphically displaying the testing status of the IDSL system.

Latching Loopback Timeout

When latching loopback timeout is enabled, latching loopbacks will drop out after 120 minutes returning the system to normal operation.

At the top right corner of the screen the time display indicates the current time. At each 15-minute interval, the performance information is transferred to the

15-minute performance data registers accessed from the Performance Monitoring screen. All 15-minute performance data registers are available for the last 25 hours. At each 24-hour interval, the performance data is transferred into the 24-hour performance data register also accessed using this screen. The Performance Monitoring screens are shown in Figure

14through Figure 18.
