摘要
The Integrated Services Digital Network terminal equipment is connected into the network via either a two-wire link or a four-wire link to a detector unit with a switch bank and auxiliary power supply. The connection is recognised automatically and switched to the corresp. termination unit. The two-wire connection when detected is converted into a four-wire one and assigned to an additional plug connector in the sense of connection of further terminal equipments. The four-wire connection when detected is switched directly to the additional plug connector.
