Abstract
An electronic exchange apparatus where an exchange unit for controlling extension-line and trunk-line interface cards unique to the exchange apparatus is provided separately from a general-purpose central control unit. The exchange unit is connected to the control unit via an Ethernet and control signals are transmitted between them. The exchange unit is allowed to have only the function of converting the communication protocols between the control-channel highway and the Ethernet which are unique to the exchange apparatus. The control unit is designed to have all of the control functions associated with exchange processing. Thus, a software can be developed easily in a short time, helping reduce development costs and keep up with advances in the CPUs and peripherals.
