indicates the status of E1 tributary 1, 2, 3 and 4.
Green Light On: The tributary is in In Service status
and no error occurs.
Red Light On: The tributary is in In Service status
but has lost signal.
Green Light Blinking: The tributary is in Remote
Loopback status.
Red Light Blinking: The tributary is in Local Loopback
status (CID control model only).
Orange Light Blinking: The tributary is receiving loopback
signal from far end.

3. Loopback Testing
This section explains the loopback testing theory. For
operation details, please refer to Unit 4 DIP Switch
Operation or Unit 5 CID Console Operation.
SA-FOM4 is equipped with loopback testing function. This
function enables user to locate the fail point of signal
connection or equipment.
Notice
Please notice that while performing loopback testing,
either local loopback or remote loopback, the
corresponding E1 tributary should be set to Out of Service
(OOS) status.
3.1 E1 Local Loopback (E1LLB)
E1 Local Loopback loops the received E1 signal
immediately to the transmit direction at the E1 input for any
E1 channel as shown in the figure listed below.

3.2 Near End (NE) Local Loopback (NELLB)
This loopback mode tests the MUX/DEMUX function of
local SA-FOM4. If the transmission quality is as expected,
the electrical session of SA-FOM4 is not the cause of
transmission problem. This function is available on CID
Consol controlled model only.

3.3 E1 Remote Loopback (E1RLB)
E1 Remote Loopback function sets remote system to
perform E1 loopback. The signal path is shown as the
following figure.
If the transmission quality is OK after E1RLB is set, the
remote E1 connection or EIO card is the major cause of the
transmission problem.

Note: The E1RLB is set by the local CID. The system will
malfunction if the E1RLB is set by remote system
simultaneously.
