【発明の名称】時間スイッチ段及びスイッチ
Document Type and Number:
Japanese Patent JP2001515670
Kind Code:
A
Abstract:
Sequence integrity and frame integrity are preserved in switching wideband connections through a switch or a switch stage. The speech memory in a switch stage in the switch is extended to include storage positions that in number correspond to the number of time slots in two frames. These storage positions are arranged into two parts of the same size in the speech memory. Furthermore, there is provided a delay control unit in the time switch stage for generating delay information based on control information in the control memory of the switch stage and a determined part of the counter information from a time slot counter circuit. This delay information controls, for each time slot, to/from (depending on if the speech memory is arranged in an outgoing stage or an incoming stage) which one of the first and second parts of the speech memory that user data is switched.
