Abstract

PURPOSE:To give flexibility to the alteration of the contents and steps of monitor and test, by performing the monitor of multiplex data in the PCM terminal station unit with the control from CPU. CONSTITUTION:The PCM terminal station 100 has the channel units 1-3, multiplex unit 4 and separation unit 5 in common to them. To perform the monitor and test for the PCM terminal station unit 100, the monitor test section 220 is installed, which has CPU7 and it is connected to the terminal station unit 100 via the terminals 271, 272, 161, and 162 in digital form. The CPU interface unit 6 is mounted in the terminal station unit 100 for the purpose of distribution and line concentration of the input and output data of CPU7 and data exchange between CPU7 and separation unit 5 is made via this unit 6.
