Chapter 4 - Hardware Description
The MPI-8 Network Interface Module
MPI is an acronym for the Multi Protocol Interface card. The MPI-8 is a serial communications interface card that uses certain protocols to communicate to endpoints, “Data Terminal Equipment” (DTE), or “Data Communications Equipment” (DCE). The protocols that it uses are RS-449, RS-530, V.35, and RS-366, which is a dialing protocol.
The MPI-8 Network Interface Module is connected to the DCE (supplied by the customer) via the MPI box. The front panel of the MPI-8 network interface contains two 160-pin connectors.
