10.Connect the serial cable running from the DCE to the appropriate 37-pin connector on the rear panel of the MPI Box. If dialing is used, connect the appropriate cable from the DCE to the 25-pin connector on the rear panel of the MPI Box.

Whenever the MGC unit is used as a DCE and connected straight to an endpoint the serial data stream flows from the endpoint (DTE) through the serial connector to the MPI box. The connections stay the same, meaning; the endpoint is connected to the back of the MPI box by way of the 37-pin connector, and the other side of the MPI box is then connected by way of the 160-pin connector to the MPI card in the MGC unit. For more information, refer to Chapter 4, “The MPI-8 Network Interface Module” on page 4-39.

•If V.35 or RS-530 cable is used, attach the special adapter (provided with the kit) to the 37-pin prior to connecting the serial cable from the DCE.

•The serial (MPI) network properties must be defined in the Network Services, For details, see MGC Administrator’s Guide, Chapter 3.
