Abstract

PURPOSE:To improve economy by dividing an incoming trunk test connector into a circuit switching part and control unit part and then by using the circuit switching part for both two-wire and four-wire lines. CONSTITUTION:When a circuit switching part is used for a two-wire line, lines A and B of circuit ICT00 are drawn toward channel testing device SPTE via the route of terminal A, contact a0 and contact b0. At the same time, the earth potential from side SPTE is supplied to main distributing board MDF by terminals J00B and J00M. When it is used for four-wire lines A and B, lines A and B of circuit ICT00 are led into SPTE via the route of terminal A, contact a0 and contact b0. At this time, J00M and J00B are disconnected. As a result, MDF is not grounded. When it is used for four-wire lines SS and SR, the route of terminal A(SS), contact a0, contact b0, and J00M and J00B is formed.
