Each of the 160-pin connectors on the MPI box interfaces to four serial ports found on the back of the MPI box. Therefore, each MPI-8 Network Interface module can be connected to up to eight ports. Each port has two connectors: 37-pin connector and the 25-pin connector. The 25-pin connector is used to dial to an endpoint over an ISDN switch. (In leased line connection this port is not used.) The 37-pin connector connects to the serial cable coming from the DCE.
