CARDS FOR NETWORK CONTROL SWITCHING CHASSIS
1.1 System Description
The system is composed of one primary Network Control Switching Chassis
and up to 63 additional extension racks. Modular cards plug into the Chassis.
This manual describes these cards.
1.2 Control Cards
Each Chassis within the system must have a control card. The control card
supervises each individual chassis in the system using an RS-232 terminal. It
is located in slot #16 of each Chassis.
There are two types of control cards: the Master Control Card with Monitor
Port (part number SM617C) and the Extension Control Card with Monitor
Port (part number SM618C).

The Master Control Card (part number SM617C) provides control for the
entire system. It is located in the primary rack chassis in slot #16 and is
addressed #00 (factory preset). There is only one Master Control Card per
system, and through the use of Extension Control Cards, it can control up
to 64 chassis.
Through a microprocessor, the Master Control Card handles all the
execution functions to be performed. It has a lithium battery backed up
memory that provides backup of all the stored information for a minimum
period of one year in the case of power failure. (The shelf life of a lithium
battery is five years.)
The card features two communication ports and one monitoring port:
• COMM IN is used for connection to the control terminal.
Communication speed is strap-selectable.
• COMM OUT is used for connection to the next chassis in the system.
• MONITORING PORT IN is the input port for on-line status monitoring,
and it is connected to the MONITORING PORT OUT on the Power
Supply Card.
