In 1999 Adherent withdrew from the DECT protocol test market to concentrate on it's MPEG-2 digital video product range.   Adherent put in place both hardware and software support programs to ensure that the installed base of clients. Support can be obtained by e-mailing them from their website.

Anritsu
Company website
The MT8801B Radio Communication Analyser, with MX880118A DECT Measurement Software, provides a high-speed tester for DECT fixed and portable parts.   The product supports a wide range of ETSI test cases as detailed in ETS 300 176-1, including such parameters as - accuracy/stability of RF carriers, timing jitter, RFP reference timing accuracy, packet transmission accuracy, transmission burst (power vs time), transmitted power, carrier modulation, emissions due to modulation and transmitter transients, receiver sensitivity, reference BER, interference performance, blocking and intermodulation.  

The equipment can establish a MAC layer communication to the device-under-test, emulating either a fixed or portable part.  Special MAC layer test messages are also supported.   A number of 'clever' features are available to enable the tester to provide accelerated product testing, to maximise testing throughput.

Traffic Monitor   - click here for a picture
The DECT monitor is a tool for monitoring DECT on-air traffic. The graphic presentation of the radio signal strength allows a quick overview of the usage of DECT channels at any point in time. In addition, the capabilities of all base stations  within the coverage area of the DECT monitor are shown.  A DECT radio module from Fraunhofer is needed for operating the DECT monitor. This module is connected with a PC by a serial communication interface.  Module details here.

Hewlett Packard
The HP 8923B makes the following measurements, which are needed to verify correct operation of the DECT transceivers: bit error ratio (sensitivity), word error ratio, carrier power, centre frequency accuracy, frequency deviation, frequency drift, timing jitter, power vs. time template, and audio.

Kirk Telecom

Kirk 1600 Handset:  A professional diagnostic tool for fault finding and deployment of DECT systems
The Kirk 1600 handset contains various features to simplify fault finding in existing DECT solutions and for setting up new DECT installations.   The handset allows the user to see all DECT systems – both business - and residential systems in the area and to find out if there are too many systems running i.e. if there is too much radio activity in the air.   Kirk 1600 can be set to find all current bases running, but it is possible – by making a selection of the RFPI no. – to search for a particular group of bases.

It is thus easy to determine the probability of having "hot spots" in the DECT system. It is possible to see how much noise there is on each of the 120 channels, with noise levels from –90 dBm to –60 dBm in jumps of 5 dBm.     The Kirk 1600 is able to lock to a base and avoid handover to other bases, enabling to see the frequencies and timeslots used and consequently to find out if special frequencies or timeslots create problems for the DECT system

DECT Type Approval Test Systems
The TS8930 systems handle tests at the air interface to CTR06
TS1210 covers acoustic tests to CTR10 and TS1220 is for protocol analysis to TBR22.

DECT Protocol Tester TS 1220 - allows approval tests of DECT fixed and mobile parts to TBR 22, expandable to TBR 10 audio tests.   The philosophy and design approach of this product was presented by Peter Riedel of Rohde & Schwarz in a paper at the DECT ’98 World Congress.

Systemes-G
Company website
The RP'SCOPE-dect is a DECT monitor system able to monitor simultaneously ALL the bearers of a DECT network ; it is particularly useful during validation phases and for operational checks.

The RP'SIM-dect is the only DECT simulator able to simulates a crowd of portables for traffic validation. All the behavioural aspects of simulation are LDS based for easy updates.  Since mid-2001 a car-mounted version of this equipment is available, ideal for checking out problems with DECT WLL deployments.

DEMON (for DEct MONitoring) - DECT monitoring product - launched May 1999
DEMON monitors all the 240 bearers (24 timeslots x 10 carriers) simultaneously, whether simple, double, or aggregated slots enabling testing of complex systems (eg WLL, DECT PABX) or phone / data.

During 2000, Systemes G introduced a  range of software add-ons including:

ISDN / LU7
DEMON call follower follows precisely every calls.  When a call is entering LU7 phase, it is able to follow and check the specific aspects of LU7 (ARQ, retransmissions).  Main messages of layer 3 of ISDN are also decoded.

DPRS
Multiple bearer reception of DEMON enables to catch every configuration of bearers involved in DPRS profile, including multiple bearer, symmetric or asymmetric, configurations. DEMON processes the on-air messages in order to decode and display the higher inter-level protocol messages up to the interworking IWU level (currently V24 and Ethernet).

SOUND DECODER
DEMON Sound Decoder extracts the audio DPCM information of non-ciphered calls and processes it into a .WAV format for output from any PC sound board. Multibearer reception of DEMON enables to follow different calls and to assign one or both ways of a call to the audio output, or to a file.

DESTURB : DECT INTERFERER SOFTWARE for DEMON
Interferer handling is one of the key points of the DECT MAC protocol. In order to thoroughly check all its defence strategy features, a programmable interferer proves invaluable. This is what DESTURB is for.  Several independent programmable interferers can emit from a few bits to a full frame, within any position regarding the DECT frame. It is also possible to define asynchronous interferers or interferers 'sticking' to a call bearer whatever the handover performed. Depending of the number of transceivers involved, up to the full DECT spectrum can be disturbed.
