Network ATM Loopback

A Network ATM Loopback is a nondisruptive test that can be run on a Virtual

Channel Connection (VCC) for an ATM link on the network interface.

Select an enabled ATM link so available VCCs can be selected for testing on the link.

The ATM Loopback causes the FrameSaver device to send either a segment or end-to-end loopback packet toward the network on the selected VCC, then wait for a response.

A RndTrip Time(ms) message appears in the Result column when a response is received within 5 seconds, indicating that the FrameSaver unit at the remote end is alive (operational and connected), and the round trip (RT) time is shown in milliseconds (ms), with a resolution of 1 ms. If a response is not received within 5 seconds, No Response appears in the Result column and the test is automatically stopped.
