摘要： In a common buffering device with a simple arrangement, a write address can be efficiently released from a buffer memory upon receipt of a multi-address call. For an ATM cell which is to be transmitted to a specific line, a write address is set in a common buffer memory, and the ATM cell is written at the write address. The ATM cell is read from an address which corresponds to the write address, and is transmitted to the specific line. Then, the pertinent write address is released. In a write table are entered a plurality of multi-address lines across which an ATM cell written at a specific address in the common buffering device can be multicast. Each time the ATM cell is read from the specific address, a designation line for transmission of an ATM cell in a read control table is compared with the multi-address lines set in the write control table. When the lines match, the write address for the ATM cell, which is set in the write control table, is released.

摘要： A system includes a host, first and second devices which operate as an acting device and a standby device, and a simplex unit controlled by the acting device. Each device is provided with a monitoring unit for monitoring the occurrence of failure, means for notifying the other device of a failure in its own device, and active/standby notification means. The active/standby notification means notifies the simplex unit that its own device is acting or standing by when the device becomes the acting device or standby device in response to a command from the host. Upon a failure in the other device when its own device is standing by, the active/standby notification means notifies the simplex unit that its own device is now an apparent acting device. Upon a failure in its own device when its own device is acting, the active/standby notification means notifies the simplex unit that its own device is now an apparent standby device. The simplex unit executes predetermined control upon accepting control data from the apparent acting device.

摘要： A transmission system which can flexibly set/change VC mode and, in case of fault, can reset the VC mode to continue communication. A transmit-side VC mode setting unit sets a VC mode according to upper-level setting or path fault information. A transmit-side signal control unit controls signals in the VC mode. A path monitoring/setting unit generates a specific pattern. A first signal transmitting/receiving unit transmits the VC mode and the specific pattern to a remote device, and receives path fault information from the remote device. A second signal transmitting/receiving unit detects the VC mode and the specific pattern and transmits path fault information to the remote device. A receive-side VC mode setting unit sets the received VC mode. A receive-side signal control unit controls signals in the VC mode. Based on the specific pattern, a path monitoring/determination unit generates the path fault information indicative of a path connection determination result.
