3.4 No Voice on a VoIP Connection

Check the POTS and line card connections between the subscriber, the MDF(s) and
the VOP line card. See your VOP User's Guide for more information on
troubleshooting VoIP problems.

3.5 Testing Wiring

Use the following tests if there is no voice.
Systematically test wiring using a functioning telephone to determine if there is a
wiring problem. If the connection is good, the telephone will return a dial tone.
Letters in the figure shown next indicate the systematic tests to be done. Suppose
you're using installation scenario "B" as shown in the chapter on MDF connections.
The logic for other scenarios should be similar.

CORRECTIVE ACTION
Make sure the subscriber has a POTS splitter properly installed.
Check the telephone wire connections between the subscriber and the MDF(s).
Check the telephone wire and connections between the MDF(s) and USER
port(s). Refer to the pin assignments in the line card User's Guide.
Check the telephone wire and connections between the MDF(s) and the CO
port(s). Check the telephone wire mapping on the MDF(s).
Check the connection from the MDF(s) to the PBX or the telephone company
PSTN or ISDN switch.
Make sure the in-house wiring works and is connected properly.
Repeat the steps above using a different DSL port.
