Abstract

The device comprises a common part (PC) connected to a central control system (SG) and terminal parts (PTi) depending on this common part. Each terminal part comprises, on one hand, access circuits (CAT) placed next to terminal circuits (CT) provided with distribution and scanning points and, on the other hand, an interconnection circuit (CRi) acting as an interface between the common part and the access circuits. <IMAGE>
