Main components of the Chassis system 47
Ethernet network interface The NTDK20 SSC card has a 10 Mbit
Ethernet network interface. The 15-pin connector, located on the back of
the chassis, provides external connection to the Ethernet network interface.
This connector is for a standard 15-pin AUI interface for a MAU.
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
Security device
A security device is required on the NTDK20 SSC card of the main and all
IP chassis expanders. The SSC card is equipped with a socket designed
to hold the security device. The security device is shipped with each new
Chassis 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 chassis
• The NT_REM required in the IP chassis expanders
Note: The NT_REM is programmed to match the main chassis device.
Both devices look identical, but can easily be identified by the label.
NTDK16 48-port Digital Line Card
The NTDK16 48-port Digital Line Card provides an interface to a maximum
of 48 digital integrated voice and 48 data ports. The NTDK16 Digital Line
Card is functionally equivalent to three NT8D02 Digital Line Cards.
Note 1: Only place the NTDK16 Digital Line Card in slot 4 of the chassis.
Note 2: The NTDK16 Digital Line Card is not required for the Chassis
system to operate.
IP expansion
For IP connectivity, four IP daughterboards are available:
• The NTDK99 single-port 100BaseT
• The NTDK83 dual-port 100BaseT
• The NTTK01 single-port 100BaseF
