Circuit Inspection Tester
MS-603
This is a circuit inspection tester for testing the circuit connection and transmission quality of general subscriber lines and OD trunk lines (compliant with the SR system 4-wire and E&M type V).
Equipment Category
Measuring instruments for telephones and facsimiles
Power supply
AC adaptor, AA batteries
It is a tester used for testing voice switched lines consisting of gateways and routers that incorporate general subscriber lines, 2-wire lines in analog extension PBXs, etc., multiplexers (MUX), in-band ringers (IBR), private branch exchanges (PBX).
MS-603 functions as a pseudo-terminal, pseudo-MUX, and pseudo-PBX to enable the testing and verification of the operating conditions of the line connection in transmission devices at opposite ends of the line.
In addition, its built-in oscillator and level meter allow the measurement of transmission quality.
For monitoring purposes, the measured data of line connection sequences can be stored in multimedia cards (MMC), thereby allowing spreadsheet software etc. for PCs to import and edit (graph creation and document handling) the data.
