Troubleshooting
On occasion, you may run into transmission problems due to any
number of factors originating from the wireless LAN. SpectraLink
8020/8030 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.
Access Point Problems
Most, but not all, handset audio problems have to do with AP range,
positioning, and capacity. Performing a site survey as described in
this document can isolate the AP 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 APs. 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 AP 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 AP 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 AP. Due to range limitations, this may be the
same as moving out of range.
