Glossary
Registration status
Registration status refers to the current status
of the connection to a mobile phone network.
If the phone is currently connected to a mobile
network, the network name will be displayed
(provided the phone transfers this information).
Other possible states include 'network search'
or 'registration failed'.
Secure Simple Pairing (SSP)
Secure Simple Pairing is a new method for the
authorisation (pairing) of Bluetooth® devices
whereby the user is no longer required to enter
a Bluetooth® code. A six-digit code is generated
and displayed on both devices to be paired.
The user simply has to confirm that the codes
match each other. This makes the pairing
process significantly more user-friendly. In
PCM, this method has been supported since
November 2012.

Signal strength
Signal strength is an indicator of the general
reception quality that the mobile phone is
experiencing in a given location. It cannot,
however, be used to evaluate the quality of a
particular call because the quality of individual
voice channels in a mobile network cell can
vary considerably. The signal strength is
displayed on CDR/PCM whenever the phone
is connected to a network cell, provided the
mobile phone shares this information.
SIM card
A SIM card (SIM – Subscriber Identity Module)
is a mandatory requirement to gain access to a
GSM network. In addition to network-specific
information used to authenticate the subscriber,
a SIM card can be used to carry user data, e. g.
phone book contacts and SMS text messages.
The card can be PIN-protected to prevent
unauthorised access to these data.
◀
Toggling/conferencing
During an active call, the user has the option
of accepting a further incoming call and then
switching between the two calls (toggling).
The user can also merge the two calls into a
three-way conference call. These functions are
supported by many mobile phones. Whether
or not these functions can be controlled by
PCM depends on the mobile phone's range of
Bluetooth® functions. These functions are not
supported by CDR.
Web radio
Web radio (or Internet radio) is an audio service
distributed by radio stations online. In PCM,
web radio is accessible via the Aha Radio app
installed on a compatible smartphone (iOS®
device or Android® device), a feature that has
been supported since November 2012.
