Troubleshooting
The Troubleshooting section includes information for the Office Module and Remote Module.
Whenever you encounter a problem, there are some general areas you should check first:
•
Ensure the AC power adapter is connected to the EXTender Module.
•
Ensure all interconnecting cables and connections to wiring blocks are secure and properly seated.
•
Ensure you are using the Remote Module at the remote site and the Office Module at the office site.
•
Verify the EXTender Module LEDs are flashing.
•
Eliminate potential causes of interference.
•
Check the error message on the telephone.
•
Verify the ISDN parameters and Dial Numbers.
No Remote Site Phone Display
•
Ensure you have a Remote Module and not a Office Module.
•
Ensure the AC power adapter is connected to the EXTender Remote and the LED is lit. Ensure the
phone is functioning correctly.
•
Ensure the installation has not been moved or any new wiring done.
No Office Module Connection
•
Ensure the correct dial numbers have been programmed into the Remote Module. Refer to Setting
the Dial Number earlier in this guide.
•
Ensure the AC power adapter is connected to the Office Module and all interconnecting cables are
properly seated.
•
Ensure you have a Office Module at the office site, and not a Remote Module.
•
Ensure your Remote & Office Modules have the correct ISDN parameters.
No Indicator Lights At Power Up
•
Ensure the AC power adapter is connected to the EXTender Module.
•
Ensure the AC power outlet is working. Check it with some other electrical device.
•
The module may not be operational (see LED sequences on next page).
Office Module Will Not Answer
•
Someone in the office could be using the port and is unaware you are trying to connect. Wait for a
short period, then try connecting again.
•
Ensure you entered the correct Office Phone Number (your Office Module DN1 number).
•
Your Office Module's DN1 may be entered incorrectly. If a DN is incorrect, the ISDN line will not
receive a call on that DN.
