Aethra D2500 Telecom Analyzer Test Tester WAN ISDN
Model Number: D2500
In good condition and in full working order
AC Power Adapter Included
Aethra D2500 Telecom Analyzer is the culmination of thirty years of experience that Aethra has in the development and production of test instruments. It has been designed to meet the requirements of technicians working in the Telecoms industry, and its range of capabilities makes it an indispensable toolkit â€" probably the only tester the engineer needs to carry around with him.
The D2500 is a versatile basic and primary rate ISDN tester capable of fulfilling needs in service turnup and maintenance, testing both lines and equipment. Used either stand-alone or with a PC and the Windows-based software, the D2500 provides error-rate analysis and rapid verification of the status of basic and primary channels. The D2500 also provides powerful D-channel signaling and protocol analysis capable of decoding EURO ISDN, DASS2, DPNSS QSIG, 1TR6 and X.25 over ISDN. Integration of a wide range of features allows the D2500 to address a wider range of applications such as Service Verification over PRI, BRI, Frame Relay Links, WAN and ISDN lines, and also testing of DCE/DTE connections over a range of interfaces.
BER tests and call generation
The D2500 has a built-in BER tester, which allows the operator to send patterns on any B channel, either towards the network (NT) or a terminal device (TE), and measure the results to G.821 standards. Functionality includes the ability to work as a sender only, a receiver only, or as both. This flexibility allows two D2500 devices to test an ISDN link in both directions simultaneously, or a single unit can be used to call from one B channel to the other (local B1-B2), put the second channel in loop and then perform a BER test to itself. The Call Generation function is designed to test quality of service in terms of call set-up success rate. The D2500 can be programmed to make a pre-determined number of calls to a destination test number with the option to hold the call on failure. Call duration and inter-call time can be specified.
Advanced analysis and protocol decoding
The D2500 is capable of monitoring and capturing and date-time stamping, in real time, protocol events on the D channel with powerful and easy analysis. The user can filter on specific layers and/or event types. Filtering is also available at the pre-capture stage, giving yet greater flexibility in operation.
Designed for practical use
The D2500 is easy to use, whether undertaking routine ISDN installation, system rollout programs, equipment testing or complex troubleshooting. For example, the built-in microphone and loudspeaker can be used in both push-to-talk and hands-free modes. Pre-defined tests can be created or selected and activated to ensure quick and consistent instrument setup.
In addition, the D2500 can be used in conjunction with external test equipment: B channels can be output to a V.11 interface for digital analysis, or to an audio jack for analogue measurements.
