摘要： In the simulation method of the present invention; one parameter is first selected from a plurality of parameters that relate to input/output characteristics. Next, regarding setting lines provided in a file for setting necessary choices from among a plurality of choices for a selected parameter, it is determined to either set choices by means of comment symbols that cause non-execution of the relevant lines, or set choices by means of identification codes, which are identifiers common to chips in which the same choice are to be set. When choices are to be set by means of comment symbols, the comment symbols of the setting lines of the necessary choices among the plurality of choices are deleted to make these setting lines effective. Alternatively, when choices are to be set by means of identification codes, the identification codes included in setting lines are rewritten to information for setting to the necessary choices. Finally, the simulation is executed.

摘要： In a scheduler having m input interfaces and n output interfaces in an ATM switching apparatus, each of m and n is an integer equal to or more than 2. The scheduler is includes a storage unit, first and second rearranging unit, a control unit and a searching unit. The storage unit stores a plurality of shuffle patterns including first to fourth shuffle patterns. The first rearranging unit carries out a first shuffling operation in units of k data (k is an integer equal to or more than 2 and less than or equal to s which is one of n and m, the other being t) and a second shuffling operation in units of u groups (u is an integer equal to or more than 2 and corresponding to s/k) to (m×n) data supplied from the m input interfaces based on the first and second shuffle patterns to produce first rearranged data. The (m×n) data are grouped into (t×u) groups. The second rearranging unit carries out a third shuffling operation in units of p data (p is an integer equal to or more than 2 and less than or equal to (m×n)) and a fourth shuffling operation in units of groups to the first rearranged data based on the third and fourth shuffle patterns to produce second rearranged data. The first rearranged data are grouped into v groups (v is an integer equal to or more than 2 and corresponding to (m×n)/p).

摘要： A switching control cell is inserted into an input cell in a switching control cell generator. In a period between the detection of a switching control cell in a first or second switching control cell detector and the detection of the switching control cell in a third switching control cell detector, in active and stand-by switches, when a cell is discarded in any one of the active and stand-by switches, in addition to priority discard control, the same cell is discarded in the other switch independently of the priority discard control. Further, upon detection of a switching control cell in the switching control cell detector, all the cells accumulated within the cell buffer are discarded, and until the detection of the switching control cell in the switching control cell detector, reading from the cell buffer is stopped so that the same cell is written into the cell buffer in the active switch and the cell buffer in the stand-by switch. By virtue of the above constitution, a switching system for an asynchronous transfer mode switch supporting a plurality of discard priority classes can be provided which realizes hitless switching.

摘要： A hitless switching system in an asynchronous transfer mode (ATM) apparatus, includes a first system switch section and a second system switch section. The first system switch section has a first cell buffer, and sequentially stores a sequence of cells in the first cell buffer to sequentially output the stored cells from the first cell buffer while performing a discard priority control to the sequence of cells. Also, the first system switch section stops the discard priority control when a switching control cell is detected in the sequence of cells. The second system switch section has a second cell buffer, and sequentially stores the input cells in the second cell buffer to sequentially output the stored cells from the second cell buffer while performing the discard priority control to the sequence of cells. When the switching control cell is detected in the input cell, the second system switch section stops the discard priority control and discards the stored cells from the second cell buffer together with the switching control cell.

摘要： In a test method and apparatus for testing a virtual path in an asynchronous transfer mode system, a sequence number is included in an operation administrating monitoring (OAM) cell to specify the OAM cell for testing a virtual path between transmission and reception sides. The sequence number is inserted into the OAM cell by the use of an idle cell and is received by a sequence number test circuit included in the reception side. The sequence number in the OAM is collated with a result of counting the OAM cell in the reception side to detect coincidence or non-coincidence between the sequence number and the result of counting. On detecting the non-coincidence, a loss of the OAM cell or wrong reception of the OAM cell is detected on the reception side. Otherwise normal operation is confirmed between the transmission and the reception sides.
