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 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.
