3.3 “No Svc” Displayed
The Wireless Telephone is either not registered, out of range, or can’t pick up a signal
from a Base Station.
1. Visually check to see if the telephone is within range of a Base Station where
other telephones are working.
2. From the Operator’s Console, search for the telephone’s serial number or
extension number to be sure it is properly registered.
3. If other telephones in the area are also not working, see M
ultiple Wireless
Telephones Not Working
below.
3.4 No Dialtone / No Audio
If the Wireless Telephone has no dialtone, or if the user is unable to hear the other party’s
voice or heard echo or dead air.
1. Be sure the Wireless Telephone is powered on.
2. Be sure the
No Svc
icon turns off a few seconds after the Wireless Telephone is
powered on.
3. Swap the Battery Pack with a Battery Packfrom a functional Wireless Telephone.
If this corrects the problem, charge the Battery Pack.
4. Turn the Wireless Telephone off then on again, then test again for dial tone and
voice quality.
5. Move through several Base Station areas to be sure the Wireless Telephone is
within range of an operating Base Station.
6. Check for alarms on the System Controller, Shelf Controller, or Interface Module
cards (F1,
Supervisor State
or F2,
Port Card State
). If the Wireless Telephone
is connected through a digital interface, the system will show an alarm. If the state
is anything but idle, the Wireless Telephone is in alarm. If there are alarms, see
Troubleshooting Alarms
section.
7. Check that the system connects when the user goes off-hook. On the Operator’s
Console, from theF2 -
Port Card State
screen, view the status of the Line when
the user goes off-hook.
8. Make sure the Wireless Telephone’s Interface Module is connected to a working
phone line. Use a telephone test set to check the line at the demarc block.
9. Check the cabling between the Interface Modules and the demarc block, and
between the demarc block and the telephone system ports. See
Link WTS – Link
3000 MCU: Installation
for more information.
10. Isolate the Wireless Telephone line on the PBX from the Link 3000 MCU.
Connect a wired telephone to the port to see if the wired telephone operates
properly.
11. Move the Wireless Telephone to a different port location and test again.
