OpenScape Cordless IP
The SIP-based cordless solution
OpenScape Cordless IP upgrades IP communications systems by a campus-wide mobility
solution.
Mobility
Providing staff with cordless phones
allows for direct, location-independent
communication and is ideally suited
for instant availability and enabling decisions to be taken quickly. This generates organizational and economic advantages.
The flexibility in the number of stations, station frequency, surface coverage, upgrading and the provision of
comfort functions with the most modern handsets characterize the system
architecture of OpenScape cordless IP.
The digital transmission standard
DECT (Digital Enhanced Cordless Telecommunication) is used worldwide
and works in a secured frequency
range.
The OpenScape cordless IP solution
also makes the established DECT standard available in Voice over IP infrastructures. SIP (Session Initiation Protocol) is used to connect to the communication systems. This enables DECT
cells to optimally complete SIP-enabled Voice over IP systems as the basis
for mobile communication solutions.
Multi-cell technology
The radio coverage required in the
building or on company grounds is
achieved by means of multi-cell technology. The synchronized cells of the
base stations installed at the company
overlap, so that calls in the entire area
of the cordless system can be seamlessly set up and made on the move (roaming and handover).
Handsets
A high degree of flexibility and mobility makes the OpenScape DECT Phone
S5 and OpenScape DECT Phone SL5
handsets for office environments, and
the OpenStage M3 handsets for industrial environments to favorites among
the cordless telephones.
The handsets offer excellent digital
speech quality, a high degree of immunity to eavesdropping, and a long range
(up to 50 meters indoors and up to
300 meters outdoors).
As well as low investment and operating costs, the phone provides simple
user prompting in connection with the
mode-dependent menu keys. This enables optimal access to the large range
of comfort features.

A further advantage is the access security in the entire OpenScape Cordless
IP system, where central registration of
the handsets in the system restricts access by unauthorized cordless telephones.
The OpenScape Cordless IP handsets
allow calls to be made in the area covered by the network.
Handsets enable the most important
SIP comfort features of the communications systems to be used on the move
within the site.
Detailed information on the individual
handsets can be found in the data
sheet for "OpenScape DECT, Handsets,
Datasheet)".
OpenScape Cordless IP
Software
The OpenScape cordless IP software
provides the interface between base
stations on the one hand and the communications systems on the other.
Router and protocol converter
The software offers the router and protocol converter functions by controlling the voice connections between the
communications systems and the respective base station. It also converts
these into a data format which the base
stations can use.
Technical data
System data
• Radio interface standard:
DECT (ETS 300 175),
GAP (ETS 300 444)
• Frequency range (Europe):
1880 MHz up to 1900 MHz
1910 MHz up to 1930 Mhz (LAM)
• Number of carriers: 10 to 12 full
duplex channels
• Voice encoding: 32 kbit/s ADPCM
• CE standard (safety)
System configuration
DECT IP base stations
Configuration and
administration
The OpenScape Cordless IP software
runs on one of the base stations.
The base stations form a network of
wireless cells and manage communications with the handsets. The multi-cell
technology enables subscribers to
move between the wireless cells with
their handsets during a call.
The base stations and the OpenScape
cordless IP software itself are all administered and configured using the
web-based management of OpenScape
cordless IP software.
• Interruption-free call transfer is
possible within up to 10 base stations.
The software of the base station contains complete DECT and IP functionality. The software does not need to be
configured and administered locally
for each base station but instead can be
conveniently operated centrally via
the OpenScape cordless IP software.
Synchronization management
The optimal location of the base stations for coverage of a building or of a
site is determined by a radio analysistechnical measurement.
Accurate time synchronization is also
necessary between the base stations
for an interruption-free call transfer.
Special antennas can be used to
increase the range.
Synchronization via DECT (synchronization over the air)
The base stations can be encased to
protect them from the weather.
A DECT IP base station must be within
the overlapping area of the cell which
this DECT IP base station forms in order to synchronize with another DECT
IP base station via the DECT interface.
In DECT systems with line-switched
connection, e.g. OpenScape cordless
Enterprise, the synchronization information is attained from the connection. This is not possible with the
OpenScape cordless IP system.
Synchronization via LAN
With this type of synchronization, the
DECT IP base stations can be synchronized via LAN. This is based on a method similar to IEEE1588.
• Up to 10 parallel calls are possible
within this group.
• Up to 50 Unify DECT devices can be
operated.
The OpenScape Cordless IP software
runs on a dedicated base station
with deactivated DECT interface.
• Interruption-free call transfer is
possible within up to 60 base stations.
• Up to 50 parallel calls are possible
within this group.
• Up to 250 Unify DECT devices can be
operated.
The management of the OpenScape
Cordless IP system runs on a virtual
server:
• The virtual server manages up to 100
DECT Managers. Up to 60 base stations can be operated on each DECT
Manager.
• Up to 10 DECT Managers and their
base stations can be connected to
form a handover domain, i.e. uninterrupted call handover is possible
between these base stations.
• Up to 5,000 parallel calls are possible
in the overall system.
• Up to 25,000 Unify DECT devices can
be operated.
Features of the SIP interface
