An asynchronous transfer mode system operates using virtual addresses VPI and VCI. Cells including these addresses are received. The data associated with these cells is stored in a table. The table contents are advantageously accessed according to a connection number. The proper connection number is more easily found by using two variables. A first variable is associated with a number of active connections. A second variable is associated with the last-used index in the table.

Message system for asynchronous transfer

A new format for asynchronous transfer mode defines a priority unspecified bit rate format; which uses the same memory structure as that used by the existing UBR and CBR traffic protocols. This format is also used for a loopback operation.
