Abstract
Abstract A switch provides time multiplex connections between ports in a telephone system. These connections are organized according to protocols located in software programs on an Integrated Multi-Protocol Processing unit (IMP). IMP includes several processing systems for processing the several protocols received by the telephone switch. Each of these IMP's then processes the respective protocol to produce switching control information. This switching control information is then transmitted to the telephone switch on a separate communications channel. The switch then uses this process protocol information to establish and remove telephone connections, according to the particular protocol received.
