Circuit cards required for the Option 11C Mini

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.

NTDK97 Mini System Controller (MSC) card

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.
