Circuit cards required for the Option 11C Mini

NTDK97 Mini System Controller (MSC) card

Chapter 12 — Installing the circuit cards
If a circuit card has a symbol of a switch on its faceplate, it is equipped with
option switches, strapping plugs, or both. Make sure that the circuit cards with
option switches or strapping plugs are set correctly. Some circuit cards can
have daughterboards and other add-on devices installed on them.
The Option 11C Mini system supports the circuit cards described in this
section. You can find a complete list of circuit cards requiring settings in the
Circuit Card Installation and Testing (553-3001-211) document.
The NTDK97 MSC card is based on the Option 11C NTDK20 Small System
Controller (SSC) card. Memory is integrated on the CPU. The MSC card does
not require a separate daughterboard. The MSC card runs X11 global
software and supports all of the NTDK20 SSC functionality with the
following differences:
• Reduced conference capability: The MSC card provides 16 channels of
conferencing with a maximum of six participants per conference call on
conference loop 29. The conference capability allows for up to five
simultaneous three-party conferences and up to two simultaneous
six-party conferences. Conference loop 30 is disabled.
• Supports 10 logical slot addresses
• Faceplate: This card does not support fiber-optic daughterboards. The
LEDs at the bottom of the faceplate show the Ethernet port link status
and collision status.
• Supports one NTDK92 Chassis Expander
You must install the MSC card in Slot 0 of the Main Chassis.
Security Device
The MSC card is equipped with a socket designed to hold the Security
Device. The Security Device is shipped with each new Option 11C Mini
system. When the MSC card is shipped, the Security Device is normally not
attached to the socket on the MSC card. You must attach the Security Device
to the MSC card during initial installation.
