access point. See the appropriate LinkPlus Integration Guide or the Configuration Note
for the access point in use at the site.
8.3 Infrastructure Problems
Calls ringing on the wrong Wireless Telephone, or multiple Wireless Telephones 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.
8.4 Dialtone Problems
A dialtone problem exists if the Wireless Telephone 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 Wireless Telephone in an active service area. If the Wireless
Telephone 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 the Access Point
Problems section.
Any initialization or error messages should turn off a few seconds after the
Wireless Telephone is powered on.
2. Swap the Battery Pack with a Battery Pack from a functional Wireless Telephone,
power the Wireless Telephone back on and check for dialtone. If this corrects the
problem, charge the Battery Pack that was removed.
3. Turn the Wireless Telephone 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 the Access Point Problems section.
5. Check for alarms on the NetLink Telephony Gateway or the NetLink SVP Server
(via System Status). If there are alarms, see Error Status for information.
6. Make sure the Wireless Telephone’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 Wireless Telephone to a different port location and test again.
