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.

simultaneously.

4. DIP Switch Operation
This function is available on DIP Switch controlled model
only. Before operation, please make sure the control model
of product purchased. For CID operation, please refer to Unit
5 CID Interface.
Three DIP switches are presented on SA-FOM4 front panel
(see the following figure).
1. E1 Service: Turn on and off the E1 service. E1 Service
switch is the left switch on Figure 7.
2. Local loopback: Turn on and off the local loopback
function. Locates on the middle of Figure 7.
3. Remote loopback: Turn on and off the remote loopback
function. This is the right switch presented on Figure 7.

4.1 E1 Service
Each E1 tributary can be set to In Service (IS) or Out of
Service (OOS) status by switching the E1 Service DIP
switch to IS or OOS.
The numbers 1, 2, 3 and 4 listed on the switch represent E1
tributary 1, 2, 3 and 4.

4.2 E1 Local Loopback
By switching the DIP Switch to LLB or NLL, user can turn
on and off the local loopback function.
LLB The corresponding tributary interface is in
local loopback status.
NLL The corresponding tributary interface is not in
local loopback status.
4.3 E1 Remote Loopback
By switching the DIP Switch to RLB or NRL, user can turn
on and off the remote loopback function.
RLB The corresponding tributary interface is in
remote loopback status.
NLL The corresponding tributary interface is not in
remote loopback status.

This function is available on CID console control model only.
Before operation, please make sure the control model of
product purchased. For DIP Switch operation, please refer to
Unit 4 DIP Switch Operation
5.1 CID Connection
Connect CID port with RS-232 to the com port of PC.
SA-FOM4 software can be run under CRT, Telix or Hyper
Terminal. When setting up, please set the Baud Rate to
9600, Data Bits to 8, parity check to none and stop bits to 1.
