Abstract

PURPOSE: To obtain a connection system for CCN forming several loops via any route by providing internal data buses and gate circuits to a common part connected to interchannel couplers CCN.
CONSTITUTION: Coupler CCNs 11W14 are connected to respective interfaces and also to common part 10. Common part 10 is provided with internal data buses AW D and gate circuits 51W58, which are connected to CCNs through signal lines 150, 160..., 450, and 460. For example, when a route for return tests is formed of CCNs 11 and 13 here, controlling signal lines 170 and 370 to "0" and signal lines 1C, A1, 3A, and C3 to "1" sends data 110 of CCN11 to CCN13 by way of connection line 150, gate 51, bus C, gate 57, and connection line 360 while data from CCN13 are transmited to CCN11 via a route of 350, 53, A, 55, and 160. a connection of this CCN can be made through the switch operation of common part 10 or under the control of each gate circuit by a command from a channel unit.
