A switch device connectable to an ISDN includes a first part which adds a calling ID information element to a first call setup message to be transferred over an ISDN tie line connecting the switch device to another switch device. The calling ID information element includes identification information on a terminal which is connected to the ISDN and makes a call.

Switch device and system

A dual-port memory is provided between an internal bus of a control unit of an exchange and a general-purpose bus such as an ISA bus or a PCI bus. A LAN controller for connecting to a LAN and a processor controller for controlling the LAN controller are connected to the general-purpose bus. In a configuration where a plurality of application processors are connected to the LAN, software for implementing a server function for enabling the application processors to be clients and a gateway function for connecting the LAN to the internal bus of the exchange is downloaded into the processor controller. In a configuration where a centralized management console is connected to the LAN, software for implementing an SNMP agent function is downloaded into the processor controller.
