The ISDN ANALYSER EIT 10 is a hand-held battery operated, multifunction - measuring instrument, intended for testing and qualifying Basic & Primary Rate ISDN. The EIT 10 provides a complete range of test functions for installation and maintenance of the ISDN. In the simulation measuring modes, the EIT 10 can be used at different reference points to check the functions of the ISDN. In monitor mode, the EIT 10 can monitor B-channel voice and D-channel signaling. It displays and records the decoded D-channel data. The EIT 10 is the ideal solution to find out and solve the problems arisen during the operation of the ISDN. The analyser can function as a telephone handset for performing in-service talk/listen or it can monitor voice quality and tones.
