Ascom d62 DECT Handset

5.20 DECT Location
Note: This is a license dependent feature, see 4.4 Upgrade Handset by License on page 11.
The parameter “DECT Location” for the Location Device must al
so be enabled. Contact the
system administrator for more information.
The DECT Location feature is equipped with DE
CT location devices which continuously
transmit location information to the handset, that is location ID and threshold value. The
handset stores the four last received location IDs, see also DECT Location Test.
When an alarm is sent, the four last stored location IDs, togeth
er with the time since they
were received, are transmitted to give an indication of the location of the handset.
In addition, the location IDs can also be sent
to the system wihtout sending an alarm (see
5.21 Special Location on
page 32), and a system/application can also request a handset’s
location (see 5.22 Poll Location on
page 32).
The handset will not indicate when receiving and s
ending the location ID. However, when
performing a location test, it is possible to configure the handset to indicate when receiving
a location ID.
In a template or Number in PDM/Devi
ce Manager, the parameter for activation is found at:
Location > DECT location
DECT Location Test
The handset will display the received DECT loca
tion data in the following format:
LR: <Number of received locations > LV: <Number of valid locations>
SS: <Signal strength>, T: <Threshold value>
L1: <Location ID>, t1: <Seconds>
L2: <Location ID>, t2: <Seconds>
L3: <Location ID>, t3: <Seconds>
L4: <Location ID>, t4: <Seconds>
LR is a counter that displays t
he number of received locations within the range of a DECT
Location Device(s), regardless of threshold level in the DECT location device is exceeded or
not.
LV is a
counter that displays the number of received locations within the range of a DECT
location device(s) with a signal strength greater than the threshold value, that is, a valid
location.
SS is the
signal strength for the current stored location.
T is the th
reshold value for the current location.
L1- L4 shows
the four last valid location IDs. The location ID with highest difference between
the measured signal strength and threshold value is regarded as the current location (L1).
This means that only one current location may exist, even if several valid locations have
been received.
t1 - t4
is a counter that displays the elapsed time in seconds since the locations L1 -L4 were
received, respectively. It stops counting when it reach its maximum value, that is, 65535
seconds.
