Obiettivo The overall objectives of this project were to produce new test strategies, methods and procedures and develop prototype test equipment for integrated broadband communications (IBC) systems for the whole system life cycle. This was to be done by designing a test bed for IBC including maintenance hardware equipment and a software test environment, bearing in mind that modern communication systems include hardware and software components that are incorporated in IBC in an inseparable manner.The test and maintenance activities of this project primarily addressed the subscriber network area, though singular items of identified equipment could also be used in other parts of the network. To achieve this, 3 targets were identified: the test bed itself, the software test bed and accompanying tasks to support them.The hardware test bed comprised: signalling, traffic load and protocol analysis/simulation equipment; optical test and maintenance equipment; channel access equipment and BER/jitter measurement equipment. These could be supported by identified items of off the shelf equipment and driven by a dedicated test system controller.The software test bed activity spanned the definition, design and implementation of an environment for IBC software test. Further existing software tools supporting all the test activities in the IBC software life cycle were to be reviewed and incorporated in the environment.The supporting tasks included software emulation of subsystems replacement and interfaces between the real system and the simulated blocks. The design of the test bed was based on a prototype broadband-integrated services digital networks (B-ISDN) system maintained for this specific reason and formed part of the objectives of the supporting tasks.Technical Summary Future (IBC) systems will be increasingly complex. Broadband services and multiple integrated data streams will place even greater stress on design tools and methods. Emerging IBC will require test equipment that takes account of the structure of the data streams. Two main scenarios have been proposed in the RDP. The structured nature of the data streams whether synchronous or asynchronous TDM will influence significantly the design of test tools and equipment.

The hardware test bed comprised: signalling, traffic load and protocol analysis/simulation equipment; optical test and maintenance equipment; channel access equipment and BER/jitter measurement equipment. These could be supported by identified items of 'off the shelf' equipment and driven by a dedicated test system controller. The software testbed activity spanned the definition, design and implementation of an environment for IBC software test. Further existing software tools supporting all the test activities in the IBC software life-cycle were to be reviewed and incorporated in the environment. The supporting tasks, apart from carrying on some RDP tasks, included software emulation of sub-systems replacement and interfaces between the real system and the simulated blocks. The design of the testbed was based on a prototype B-ISDN system maintained for this specific reason and formed part of the objectives of the supporting tasks.
