DEVICE OF PROCESSING CALL IN TELEPHONE EXCHANGE SAVING IMPROVED MODEL SPACE SWITCH AND CONTROL METHOD THEREOF

摘要

The invention has improved the space switch, which allows to implement the enhanced space switch is mounted replaceable in-flight call processing apparatus and relates to a control method, in particular, the exchange-flight call processing through the improved space switches having one of the shelf structure device mount exchanged relates to a cabin call processing apparatus and a control method, according to the present invention the exchange cabin call processing device is improved space switch mounted by and a control method, exchange with improved space switch capable composed of one of the shelf-flight call by giving implement the treatment apparatus, can be a system configuration space is the space switch structure occupies is reduced on the exchange system hardware efficiently, which results is excellent as well as the system manufacturing cost reduction, is the use in small-capacity wire exchange possible there is an effect.
