helping them rectify hardware faults related to off-hook and playing of dial tone, busy tone, and
ringback tones.
8.7 POTS Port Loop Test
There are two kinds of loop tests: hardware tests and service tests. Loop tests used to test the
hardware and data configuration associated with the plain old telephone service (POTS) service.
Test personnel can use the test results to locate service faults.
8.8 Call Emulation Test
The call emulation test is used to emulate a voice user to make a call, and then check whether
the configuration of the voice service is correct based on the test result. When the voice service
is faulty, the result of the call emulation test is used to locate faults.
8.9 PPPoE Dialup Emulation Test
In the PPPoE dialup emulation test, the test device is emulated as the PPPoE client to perform
the dialup test on the BRAS. Thus, the test is used to check whether the PPPoE dialup is
successful through the check on the connectivity between the MA5612 and the BRAS. When
the PPPoE dialup fails, the result of the PPPoE dialup emulation test is used to locate faults.
8.10 Multicast Emulation Test
In the multicast emulation test, the test device is emulated as the multicast user to request for
programs. Thus, the test is used to check whether the communication between the device and
the multicast program source is normal through the check on whether the multicast program
stream arrives at the device. When the multicast user fails to request for programs, the result of
the multicast emulation test is used to locate faults.
8.11 DHCP Dialup Emulation Test
In Dynamic Host Configuration Protocol (DHCP) dialup emulation, an MA5612 simulates a
DHCP client and applies for an IP address from a DHCP server. The DHCP emulation tests
connectivity between the MA5612 and the DHCP server and verifies the DHCP configurations
on a DHCP relay, DHCP proxy, and DHCP server.
8.12 Capturing Voice Packets Remotely
You need to collect fault information such as signaling information and Dbwin information to
locate a fault when the voice service is faulty. This topic describes how to use the remote voice
packet capture function to obtain fault information and locate a fault, reducing onsite
maintenance workload.
8.13 Capturing Packets by Using Port Mirroring
Capturing packets on an Ethernet port allows you to monitor the traffic on a device, diagnose
network faults, and analyze the data. This requires a packet capture tool connected to the uplink
Ethernet port, which may interrupt the service on the uplink Ethernet port. Port mirroring
function allows you to mirror the packets on an Ethernet port to an idle Ethernet port and to
capture the packets to the destination port, preventing service interruption on the source port.
This topic describes how to capture packets by using port mirroring on an Ethernet port.
