Network and Data Port PVC Tests do not appear on the Test menu when no PVCs have been configured on the interface.

Network ATM Loopback Tests does not appear if no ATM links are enabled on the network interface.

Tests can be commanded from the OpenLane SLM system using its enhanced Diagnostic Troubleshooting graphical interface, as well as from the menu-driven user interface.

Test Timeout Feature

A Test Timeout feature is available to automatically terminate a test (as opposed to manually terminating a test) after it has been running a specified period of time.

It is recommended that this feature be used when the FrameSaver device is remotely managed through an inband data stream (PVC). If a test is accidently commanded to execute on the interface providing management access, control is regained when the specified time period expires, automatically terminating the test.

To use this feature, enable the Test Timeout configuration option, and set a duration for the test to run in the Test Duration (min) configuration option (see Configuring General System Options in Chapter 4, Configuration Options).

NOTE:

These configuration options do not pertain to tests commanded by the DTE, like a DTE-initiated External Loopback.
