5.4.7 IP DECT System
The IP DECT system is based on the DECT GAP standard and inte-
grates to MX-ONE via SIP, thus a SIP extension license is needed in
MX-ONE for each DECT user. The handsets supported in the IP DECT
system are the same as are use in the Integrated DECT system. The IP
DECT system can be integrated with external applications such as
different alarm systems, networks and e-mail. This gives features such
as; messages to handset, alarm from handset, message acknowledge-
ment, and absent handling.
For more information on cordless phones, see the description for IP
DECT SYSTEM.
5.4.8 Integrated DECT system
Using DECT cordless phones enables users to make and accept calls at
any location in the coverage area of its base stations. The integrated
DECT feature is compliant to the DECT GAP/CAP standards, which
ensures desktop phone speech quality and high security from wiretap-
ping.
The cordless feature consists of a number of software units, specific
hardware/firmware units (the ELU31 DECT base station interface
board), external Radio Fixed Parts (RFP) and Portable Parts (PP). Cord-
less extension is a fully integrated extension type in MX-ONE and can
use most of the features available in the system. The ELU31 boards are
installed in MX-ONE gateways and can be distributed throughout the
synchronization area. To secure synchronization of the DECT air-frames
the ELU31 boards has a dedicated synchronization structure.
For more information on cordless phones, see under the folder or
CORDLESS TELEPHONES.
The DECT Short Message Service (SMS) performs transfer of text
messages, which can be up to 140 bytes long (giving, for example, 160
Latin characters). SMS is available for integrated Cordless extensions
(DECT) in MX-ONE Telephony System. Text messages can be received
in any call state, that is, for example, during an ongoing call. To be able
to send and receive SMS messages CPDM message and alarm server
needs to be connected to the MX-ONE system.
