Digitone receiver, tone generation, tone detection functions

The NTDK20 SSC card provides the following Digitone and other tone
functions related to tone:

•

30 channels of Tone and Digit Switch (TDS) and a combination of eight
Digitone receivers (DTR) or Dial Tone Detectors (XTD)

•

Tone service ports, which can be configured as either four units of
MFC/MFE/MFK5/MFK6/MFR or eight DTR/XTD units

Software daughterboard

The NTDK20 SSC card requires a software daughterboard in order to
function. The NTTK25 Software daughterboard provides storage for system
and customer data. It can be ordered preprogrammed with system software
and customer data.

For CS 1000 Release 4.5 software, the minimum requirements are:

•

32 MB DRAM

•

16 MB primary flash

•

32 MB program store

An NTDK20 SSC card with 32 MB DRAM and equipped with an NTTK25 or
NTTK13 Software daughterboard meets the minimum requirements.

Security device

A security device is required on the NTDK20 SSC card of the main and all
IP expansion cabinets. The SSC card is equipped with a socket designed
to hold the security device. The security device is shipped with each new
Cabinet system. When the SSC card is shipped, the security device is
normally not attached to the socket on the SSC card. You must attach the
security device to the SSC card during initial installation.

There are two types of security devices:

•

The NT_STD required in the main cabinet

•

The NT_REM required in the IP expansion cabinets

Note: The NT_REM is programmed to match the main cabinet device.

Both devices look identical, but can easily be identified by the label.
