An agent (211, 110, 1111, 1161) position, for use by an agent of a business, communicates with the circuit (154) and packet (155) switching network of a telecommunication switching system using an Integrated Services Digital Network (ISDN) B-channel (205) and D-channel (204). The switching networks are connected to customers (170, 171), positions (160, 161, 211), data communication paths (147, 169) to data bases (149, 150), and a data path (156) to a control processor (151) of the system. The B-channel is connected through a circuit switching network (154) to a customer. The D-channel is connected through a packet switching network (155) to the control processor (151) and to data bases (149, 150). Advantageously, the position can be located remotely from the switching networks because only a single integrated facility is required to transmit the integrated voice and data signal between a position and the network. Advantageously, a variety of data bases can be rapidly and efficiently accessed by a position. |
