figd.txt - Detailed Description of the images.


fig1a2.gif - FIG. 1 diagrammatically illustrates a telephone central office switch having a no test trunk, through respective T, R, S and G leads of which a line-conditioning and test device, such as a direct access test unit, may be controllably connectable to a selected one of any of the line circuits served by the central office.

FIG. 2 diagrammatically illustrates an Ericsson ARF 101/102 central office switch.

fig3a5.gif - FIG. 3 diagrammatically illustrates a Standard Electric PC-1000 central office switch.

FIG. 5 shows a test interface adapter installed between a DATU and A, B, S, S1, S2, SL, BL and G leads of a Standard Electric PC-1000 central office switch.

fig4.gif - FIG. 4 shows a test interface adapter according to the present invention installed between a DATU and A, B, C, D and G leads of an Ericsson ARF 101/102 central office switch.

fig6a8.gif - FIG. 6 shows the internal signal mapping components of the interface adapter of the present invention.

FIG. 8 schematically illustrates an NTT sleeve termination and current level sensor unit of the interface adapter of FIG. 6.

fi7.gif - FIG. 7 schematically illustrates the circuitries of the battery voltage conditioning unit, A/B cut through unit, and tone detector unit of the interface adapter of FIG. 6.
