SSC card and components

Memory, processing, and data storage 23

The NTDK20 SSC card controls call processing, stores system and customer data, and provides various expansion interfaces. It includes the following components and features:

•ﬂash daughterboard memory, DRAM, and backup memory

•two expansion daughterboard interfaces

•PC Card socket

•three Serial Data Interface (SDI) ports

•32 channels of Conferencing (64 if two single-port expansion daughterboards are present, or 96 if two dual-port expansion daughterboards are present)

•10 Mbps network interface

•30 channels of Tone and Digit Switch (TDS) and a combination of eight Digitone Receivers (DTR) or Dial Tone Detectors (DTD)

•Networking and Peripheral Signaling

•additional tone service ports (four units of MFC/MFE/MFK5/MFK6/MFR or eight DTR/XTD units)

The SSC card requires a Software Daughterboard in order to function. The Software Daughterboard can be ordered preprogrammed with system software and customer data.

A security device is required on the SSC card of the Main and all Expansions. The security device, which remains on the SSC card for the life of the system, is used for system identiﬁcation. This device allows the activation of features assigned to the system, through the use of a series of keycodes. The system uses keycodes for validation purposes.

Signaling Server

CS 1000M Small Systems use a Signaling Server. The Signaling Server is an industry-standard, PC-based server that provides a central processor to drive H.323 and SIP signaling for IP Phones and IP Peer Networking. It provides signaling interfaces to the IP network using software components that operate on the VxWorks™ real-time operating system.

The Signaling Server has both an ELAN and TLAN network interface. The Signaling Server communicates with the Call Server through an ELAN subnet.

The Signaling Server is mounted in a 19-inch rack. The Signaling Server can be installed in a load-sharing redundant conﬁguration for higher scalability and reliability.
