or access point. See the appropriate LinkPlus Interface Guide or the Configuration
Guide for the access point in use at the site.
9.3 Infrastructure Problems
Calls ringing on the wrong handset, or multiple handsets not working, are likely to be
caused by faulty installation. The wires that connect the demarcation (demarc) block
to the NetLink Telephony Gateway could be installed incorrectly.
Contact your wireless LAN and/or PBX vendor for more information about
troubleshooting infrastructure problems.
9.4 Dialtone Problems
A dialtone problem exists if the handset has no dialtone, or if the user is unable to
hear the other party’s voice, hears echo or hears dead air. Dialtone 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
dialtone in an active area, continue with the steps below. If the no dialtone
problem is limited to a certain area, see section 9.1 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 dialtone. If this corrects the problem, charge the
Battery Pack that was removed.
3. Turn the handset off, then on again, and then test again for dialtone. If OK,
place a call and determine voice quality.
4. While maintaining an active call, walk through several access point areas. If
fluctuation occurs see section 9.1 Access Point Problems.
5. Check for alarms on the NetLink Telephony Gateway or the NetLink SVP
Server (via System Status). If there are alarms, see SpectraLink 8000 Telephony
Gateway: Administration Guide for SRP or SpectraLink 8000 SVP Server:
Administration Guide for SRP for information.
6. Make sure the handset’s gateway port is connected to a working phone 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.
