The Remote Loopback Switch (SW500)
The Remote Loopback Switch is factory configured to the left (Off) position for normal
mode (default), as shown in Figures 15. Once the firmware is downloaded, you can set
the Remote Loopback Switch to the right (On) position for loopback mode, as shown in
Figure 16. Loopback mode enables you to verify the T-1 connection. The switch
overrides any board modes set by the Dialogic System Software. The Remote Loopback
Test Indicator above the Remote Loopback Switch will light when the linecard is set to
loopback mode.
