Tone services
The NTDK20 SSC card incorporates the functions of the existing NTAK03
TDS/DTR, NT5K20 XTD and NT5K48 XTD cards.
The NTDK97 Mini System Controller (MSC) card is used exclusively with
the Option 11C Mini Main cabinet when one (only) expander chassis is
connected to the Mini Main. It controls call processing and stores system and
customer data. The NTDK97 MSC card is comprised of the following
components and features:
•
Flash memory, DRAM, Boot ROM, and Backup memory
•
One PCMCIA socket
•
Three Serial Data Interface (SDI) ports
•
16 channels of Conferencing
•
One Ethernet (10 Mbps interface) port
•
30 channels of tone and digit switch (TDS) and a combination of eight
Digitone receivers (DTR) or dial tone detectors (XTD)
•
Networking and Peripheral Signalling
•
Additional tone service ports (four units of MFC/MFE/MFK5/MFK6/
MFR or eight DTR/XTD units)
Flash Memory
The majority of system and customer configured data is both controlled and
stored on the NTDK97 MSC card's Flash ROM. (This memory is located on
the motherboard. It is not on a separate daughterboard as is the case for the
NTDK20.)
