4. Additional Function
4.1 Loopback
XG2 has loopback function for the trouble shooting of network. Loopback test is the method to
send out signal and quickly back to the same source entity to test the transmission and route
problem of infrastructure. Test equipment with this troubleshooting technique sends specific
patterns, and counts any errors that come back (BERT, Bit Error Rate Test).
From the operation of console port, user can active loopback test. When it is enabled, data
stream from test equipment to the XG2 flows returns to their source entity.
Here it illustrates how loopback works.
A
: XG2 that loopback function is enable for other test equipment or network infrastructure.
B
: Signal with test patterns such as BERT is sent.
D
: Signal with test patterns is back to original entity (test equipment).
C
: Network equipment or test equipment with 10GBASE-T port that is able to send test patterns
with destination of itself via XG2
E
: Network equipment or test equipment with 10GBASE-R port that is able to send test patterns
with destination of itself via XG2
