Abstract

DSPA311(Analog Subscriber Line Board Assembly) is offer the interface of between analog subscriber and TDX-100 exchange system. DSPA311 is belong ASI block, accommodate dial and MFC telephone subscriber of 32 channel, and voice signal designed for interface with TSW, and 2 and 4 wire loop impedance is 600 (ohm). DSPA311 is consist 4 channel daughter beard QSLM-10(Quad Subscriber Line Module-10) and perform BORSCHT and be possible A/U-law select and GAIN value control by data control of DSPA171(Device controller I). In this Paper, We described the function test program for the DSPA311 Board by using the HP3070CT combinational test system, and an unmanned automatic test system.
