are the same on the test equipment as it is on
the 64G module.
7. Put the FOCUS framer(s) in loop back.
You do this through the FCS.
To make the loop back using the FCS,
execute the “Framer Local Loop Back…”
command on the FCS “Test” menu for each
transceiver (X1-1 and/or X2–1) on the
chassis. (See the FCS online help facility:
Loop Back Functions ↓ Transceiver Loop
Back Tests ↓ Turning On a Loop Back Test).
This method loops the signal back through the
64G module and the test set.
8. Observe the test results.
If the TX and RX LEDs on the module are lit,
this indicates that data is flowing through the
64G module. Also, if the Bit Error and Block
Error windows on the test set display a zero
(0), this indicates that data is flowing error
free and continuously through the 64G
module and the test set.
