Problem with a splitter card or the splitter chassis.

Reconnect the Telco-50 cable to the splitter chassis’ Telco-50 

CO

 connector.

Disconnect the Telco-50 cable from the splitter chassis’ Telco-50 

USER

 connector. Connect 

a telephone to the appropriate pins of the splitter chassis’ Telco-50 

USER

 connector (refer to 

the line card User’s Guide for the proper pin assignments). 
If there is no dial tone, make sure that the splitter card is properly installed. Try a different 
splitter card. If using a different splitter card solves the problem, replace the first splitter card.
If using a different splitter card does not solve the problem, the splitter chassis may be faulty, 
contact your vendor.

E

Wiring problem between the USER Telco-50 connector on the splitter chassis and MDF 
3.

Reconnect the Telco-50 cable to the splitter chassis’ Telco-50 

USER

 connector.

Connect a telephone to a lower port of MDF 3. If there is no dial tone, then the problem is 
between the splitter chassis Telco-50 

USER

 connector and MDF 3. Replace the Telco-50 

cable connecting the 

USER 

port to MDF 3.

If the problem remains, check the pin assignments of the USER Telco-50 connector. If the 
problem remains, then the IES-6000 or MDF 3 is faulty. Repeat the test in step A using MDF 
3 to determine if MDF 3 has problems. Contact the telephone company if that is the case.
If not, contact your IES-6000 vendor outlining the problem and the steps you took to solve it.

F

Building-wiring problem between the subscriber’s wall jack and MDF 3.

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.
