Dial Tone Problems
A dial tone problem exists if the handset has no dial tone or if the user
is unable to hear the other party’s voice, hears echo or hears dead air.
Dial tone problems can be caused by a number of different situations
and should be investigated by following these steps:
1. Power on the handset in an active service area. If the handset does
not get a dial tone in an active area, continue with the steps below.
If the no dial tone problem is limited to a certain area, see Chapter
8, section Access Point Problems.
Any initialization or error messages should turn off a few seconds
after the handset is powered on.
2. Swap the Battery Pack with a Battery Pack from a functional
handset, power the handset back on and check for dial tone. If this
corrects the problem, try recharging the Battery Pack that was
removed.
3. Turn the handset off, then on again, and then test again for dial
tone. If functioning, place a call and determine voice quality.
4. While maintaining an active call, walk through several AP areas.
If fluctuation occurs see Chapter 8, section Access Point Problems.
5. Check for alarms on the SpectraLink 8000 Telephony Gateway or
the SpectraLink 8000 SVP Server (via System Status). If there are
alarms, see SpectraLink 8000 Telephony Gateway: Administration
Guide or SpectraLink 8000 SVP Server: Administration Guide for
information.
6. Make sure the handset’s gateway port is connected to a working
telephone line. Check the line at the demarc block. You may need
to contact your vendor to perform this check.
7. Check the cabling between the gateway and the demarc block and
between the demarc block and the telephone system ports.
8. Move the handset to a different port location and test again.
