Chapter 55 Troubleshooting

Table 106 Testing In-house Wiring (continued)

STEP

TEST

E

Reconnect the telephone wire to USER.

 

Connect a telephone to a lower port of MDF 3. If there is no dial tone, then the problem is

 

between your device and MDF 3. Check the pin assignments of the telephone wire’s

 

connector that connects to USER. Replace the telephone wire connecting your device to

 

MDF 3.

 

If there is no dial tone, then MDF 3 may be faulty. Contact the telephone company if that

 

is the case.

 

 

F

Disconnect the DSL modem from the wall jack and connect the telephone to the wall

 

jack. If there is no dial tone, then there is a problem with the building wiring between the

 

DSL subscriber’s home and the MDF. Contact your telephone company for

 

troubleshooting.

 

 

55.8 Local Server

The computer behind a DSL modem or router cannot access a local server connected to the IES-612-51A.

Table 107 Troubleshooting a Local Server

STEPS

CORRECTIVE ACTION

 

 

1See Section 55.5 on page 408 to make sure that the subscriber is able to transmit to the IES-612-51A.

2Make sure the computer behind the DSL device has the correct gateway IP address configured.

3Check the VLAN configuration (see Chapter 16 on page 145).

4Check the cable and connections between the IES-612-51A and the local server.

5Try to access another local server.

If data can be transmitted to a different local server, the local server that could not be accessed may have a problem.

55.9Data Rate

The SYNC-rate is not the same as the configured rate.

Table 108 Troubleshooting the SYNC-rate

STEPS

CORRECTIVE ACTION

 

 

1Connect the DSL modem or router directly to the DSL port using a different telephone wire.

2If the rates match, the quality of the telephone wiring that connects the subscriber to the DSL port may be limiting the speed to a certain rate.

If they do not match when a good wire is used, contact the distributor.
