Switch network for subscriber capacity expansion of small capacity exchanges

摘要

The present invention relates to a switch network for expanding subscriber capacity of a small capacity electronic switching center (DTS-1100), and is connected to a peripheral matching device to perform a time slot exchange function, a network synchronization function, a conference call function, A plurality of time location devices; A matrix switch device for receiving subscriber's telephone channel data, matrix switch control data and clocks output from the plurality of time switch devices and performing bit rate conversion, storage and reading to perform a space division switching function; And a plurality of time switch processors for exchanging time slot exchange information with the switch devices. Thus, the capacity of telephone subscribers and trunk lines of existing small capacity switches can be expanded up to four times.
