Abstract

PURPOSE:To make it possible to debug a program economically under easy control, by constituting the exchange of an off-line system while disconnecting a stand-by unit and some units divided into groups from an in-use unit. CONSTITUTION:As in-use units for normal switching operation, central processor 11, signal transmitter-receiver 13a1, switch controller 13b1, and signal distributor- scanner 13c1 are used. To constitute a debugging system, central processor 12, switch controller 13b2, signal distributor-scanner 13c2 and subscriber's circuit group 14n of the stand-by system, and switch network 16m and trunk group 18p are all disconnected from the in-use system. Next, the above-mentioned disconnected units, and the network and trunk group are connected by switch control line 13f2, trunk control line 13g2 and channel control bus 13e2 to constitute a debugging exchange. A program to be debugged is loaded into unit 12 of this debugging exchange for program debugging.
