Parameter/Line
Description
RPN
The line contains the list of base stations identified by the handset or RPNs of
the RFP-table entries in respect to the RSSI-values below. Up to 5 RPNs can be
displayed.
The Radio Fixed Part Number (RPN) is an 8-bit DECT cell identity allocated by
the installer. The allocated RPN within a cluster must be geographically unique.
-dBm (Signal
Strength)
This indicates the actual field strength information (RSSI) for the base station
the current handset is locked to and additional RFPs stored in the RFP-table.
RSSI unit is -dBm. The RSSI value of the RFP-table is updated in a 250ms cycle.
This causes an update of any entry in a table with 3 RFPs every 3 * 250ms =
750ms.
If the RFP could not be synchronized for an RSSI-update, the RSSI value is
decreased. This implies that an entry will be deleted after a while, if e.g. the
dummy-bearer position has changed or the RFP is unreachable.
FE PP:XX FP:XX
Indicates the number of sync/CRC errors (frame-errors) within the last update
cycle.
This information is only valid for the existing link to the current handset located
to the relevant base station.
The PP value is the number of detected Sync/CRC error(s) within the last 100
