4.3.4 Interface Cable

The FIC-SAE cards use synchronous/asynchronous serial interface cables with DB-28
connectors.
Before connecting an FIC-SAE card, identify the line properties and then select the
proper interface cable from the following ten cable options:
V.24 (RS232) DTE cable: DB-25 plug at the network end
V.24 (RS232) DCE cable: DB-25 receptacle at the network end
V.35 DTE cable: 34PIN plug at the network end
V.35 DCE cable: 34PIN receptacle at the network end
X.21 DTE cable: DB-15 plug at the network end
X.21 DCE cable: DB-15 receptacle at the network end
RS449 DTE cable: DB-37 plug at the network end
RS449 DCE cable: DB37 receptacle at the network end
RS530 DTE cable: DB-25 plug at the network end
RS530 DCE cable: DB25 receptacle at the network end
All these cables use a DB-28 connector to connect the router, but the connector at the
network end varies with the type of the to-be-connected network.
