3. Check the LED on the Switch Module and compare it to the
LED diagnostic sheet as in Table 4-1. The Switch Module may
be defective.
4. Check that the DIP switches on the Switch and Remote
Modules are set properly. Unless your system administrator
tells you otherwise, all of the DIP switches should be OFF.
5. Have there been any electrical storms that may have popped
the line fuses?
6. Go on-line and monitor call progress on the Remote Module
speaker.
7. If there still is no dial tone, do the following:
a. Check the cables on the Remote Module; replace if
necessary.
b. Use a regular telephone to get dial tone on the CO line
jack. If there is no dial tone, check the installation wiring
or call the telephone company. If there is dial tone
present, the cable to the Module or a popped line fuse is
probably the problem.
8. If there is a ring but no answer, do the following:
a. Check the telephone number.
b. Check the power for the Switch Module.
