Modular test system for ISDN units - uses plug adaptors to connect units to testing unit which simulates ISDN control and data exchange

摘要

The modular test system described has been formed from a standard commercial personal computer and a testing unit, with components usign ISDN techniques. The units to be tested are connected to the user interface of the communications station and a control computer is coupled with the testing unit. Plug adaptors connect the units to the testing unit. The testing unit simulates an ISDN control can data exchange with the aid of a processing package Errors are analysed by a telecommunications monitoring module. USE/ADVANTAGE - For telecommunications industry. Improved quality of units suitable.
