9. Troubleshooting
NetLink e340, h340, and i640 Wireless Telephones can exhibit transmission
problems in several ways. They can cease functioning properly, display error
messages, or display incorrect data. When using and troubleshooting handsets,
consider the following problem sources to determine the best method of
approaching any specific situation.

approaching any specific situation.
9.1 Access Point Problems
Most, but not all, handset audio problems have to do with access point range,
positioning and capacity. Performing a Site Survey as described above can isolate the
access point causing these types of problems. If the handset itself is suspected,
conduct a parallel Site Survey with a handset that is known to be properly
functioning.

In range/out of range
Service will be disrupted if a user moves outside the area covered by the wireless
LAN access points. Service is restored if the user moves back within range. If a call
drops because a user moves out of range, the handset will recover the call if the user
moves back into range within a few seconds.

Capacity
In areas of heavy use, the call capacity of a particular access point may be filled. If
this happens, the user will hear three chirps from the handset. The user can wait until
another user terminates a call, or move within range of another access point and try
the call again. If a user is on a call and moves into an area where capacity is full, the
system attempts to find another access point. Due to range limitations, this may be
the same as moving out of range.

Transmission obstructions
Prior to system installation, the best location for access points for optimum
transmission coverage was determined. However, small pockets of obstruction may
still be present, or obstructions may be introduced into the facility after system
installation. This loss of service can be restored by moving out of the obstructed
area, or by adding access points.

9.2 Configuration Problems
Certain problems are associated with improper configuration of either the NetLink
Telephony Gateway, NetLink Wireless Telephone, or NetLink SVP Server.
For instance, no extension displayed or wrong extension displayed on the handset
has no effect on its operation but serves to easily identify it. Other configuration
problems, like having incorrect menu items, or inability to connect or access
telephone system features, affect the handset’s functioning.
Configuration problems are generally corrected by changing the configuration at the
NetLink Telephony Gateway, the NetLink SVP Server, or on the handset. See the
SpectraLink 8000 Telephony Gateway: Administration Guide for SRP document for
specific configuration steps. There may also be incorrect programming of the PBX
Telephony Gateway, NetLink Wireless Telephone, or NetLink SVP Server.
