This technical note describes some operating characteristics of a multipurpose concentrator for a switch and a method for analyzing such a concentrator in a priority environment. Messages from several classes are buffered by the concentrator and subsequently released to the switch, on a call intermittent basis, in accordance with two rules. In the first rule, release is based on the number of messages in a buffer. In the second rule, a message is not allowed to remain in the buffer longer than a prespecified amount of time. For each rule, analytic expressions for the waiting time of an arriving message at the buffer and the arrival rate into the switch are given. Analogous expressions are given for the case in which one class of message is given priority over all the others. That is, the buffer is released under the rules described above when the appropriate levels for the priority messages have been reached. Author
