There are three types of call emulation tests: caller emulation test, callee emulation test, and
automatic emulation test. The call emulation test is irrelevant to protocols for the upstream
transmission. That is, it is applicable to SIP and H.248.
Before enabling an automatic emulation test, you need to enable a callee emulation test and then
analyze the test according to the returned results. The test is performed automatically.
Impact on the System
l
After callee emulation is enabled on the POTS port, the callee cannot hear the dial tone
after offhook but hears mute. After the POTS port is enabled with callee emulation, services
carried on the POTS port are interrupted. These services will be recovered after callee
emulation is complete.
l
After a POTS port is enabled with callee emulation, if the user of this port is not called by
a caller, the user will exit callee emulation in three minutes. Within these three minutes,
the VoIP service and other services are interrupted.
l
After a POTS port is enabled with the automatic emulation test, services carried on the
POTS port are interrupted. These services will be recovered after automatic emulation is
complete.
Precautions
l
Before enabling an automatic emulation test, enable a callee emulation test. This is because
when an automatic emulation test is enabled, the dialing operation will be automatically
performed. If the callee is not in the callee emulation state, the test will fail.
l
In the automatic emulation test, the preset called number must be the number of the callee.
Procedure
Step 1
Enable a callee emulation test for the callee. For details, see
Callee Emulation Test
.
Step 2
Enable an automatic emulation test for the caller.
1.
In the

Result
After an automatic emulation test is enabled, the caller automatically dials the number of the
callee to call the callee and the callee picks up the phone automatically. After the test is complete,
test results are displayed on the NMS.
4.5.8 Local Loopback and Remote Loopback on a POTS Port
The local loopback and remote loopback on a POTS port are used for determining the section
of the line where VoIP service failures occur.
Prerequisite
l
The user is a user with the operator authority or higher.
l
The OLT and the NMS communicate with each other properly.
l
The NMS is able to discover an online ONT and VoIP service parameters are configured.
Impact on the System
After loopback is set on a POTS port, normal communication is interrupted and an echo is heard
by the caller.

Precautions
l
The loopback can be set only after a call is set up.
l
After onhook, the communication ends and loopback is cancelled automatically.
l
Direct switching between local loopback and remote loopback cannot be performed. To
switch between local loopback and remote loopback, cancel the current loopback first.
Procedure
Step 1
Make calls between VoIP users on an ONT.
Step 2
In the
Physical Map
navigation tree on the
Main Topology
tab page, double-click the target
OLT, or select the target OLT, right-click, and choose
NE Explorer
.
Step 3

tab in
the lower pane.
Step 6
Select a record from the list whose
UNI Type
is

, right-click, and choose
Config Port
Loopback
from the shortcut menu, as shown in the following figure.

Step 7
In the dialog box that is displayed, select a loopback type and click
OK
to start a test. The
loopback types include
No Loopback
,
Local Loopback
, and
Remote Loopback
.
----End
Result
l
After local loopback is set, the local voice is audible. If the local voice is not audible, the
POTS port of the ONT is faulty.
l
After remote loopback is set, the peer end can hear his/her echo. If the echo is not audible,
the link from the peer end to the local ONT is faulty.
The communication recovers after loopback is cancelled or the phone is placed on the hook.
4.5.9 VoIP Loop-Line Test
A VoIP loop-line test is used for locating a fault that occurs on wires A and B. It includes the
voltage test, resistance test, and current test.
