Asynchronous transmission mode switch and control method of the asynchronous transmission mode switch |
摘要 |
An ATM switch comprises a detector that detects impairments in signal lines, and a controller that controls the preservation of paths that have been established by call control via a signal line when an impairment has been detected on a signal line by the detector. When an impairment has occurred only on a signal line, interruptions in communications services are prevented by causing the data line paths to be preserved rather than released.
