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.
Network ATM Loopback Tests Screen Example
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.
