The NTDK20 Small System Controller card (used with Option 11C), and the
NTDK97 MSC card (used with Option 11C Mini) are each equipped with
three SDI ports.
Each port can be used to connect a modem or terminal to the system. If
connection to a terminal is desired, an A0378652 NO modem (NULL modem
without hardware handshaking) is required.
For the Option 11C, the SDI port connector is located at the bottom rear of
the cabinet next to the connectors to the cross connect terminal. (An NTBK48
three-port cable is required to connect to system equipment.) Refer to
Figure 25 on page 229.
