SDI ports

The SSC card has three Serial Data Interface (SDI) ports used to connect
on-site terminals or remote terminals through a modem. The SDI ports are
available using the NTBK48BA three-port cable. Table 2 lists the default
settings on the ports.

Note: The baud rate shown for ports 1 and 2 is the default rate. You can configure
ports 1 and 2 in software to a maximum baud rate of 19200 bps.

Ethernet interface

The SSC card has a a 10 Mbps Ethernet port. A 50-pin connector located in
the 11C Main cabinet provides external connection to the Ethernet port. The
11C Mini provides external Ethernet connection via a standard Ethernet
Media Access Unit (MAU) connector located on the rear of the Main chassis.

Conferencing

The SSC card provides 30 conference channels. When you add Fiber
Expansion daughterboards to the SSC card, conference capability increases.
Each port on the Fiber Expansion daughterboard increases the total number
of conference channels by 16.

Digitone Receiver, tone generation, tone detection functions

The SSC card provides the following Digitone and other tone-related
functions:
• 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
You can install an NTAK03 card in the Main cabinet/chassis if additional
tone and receiver transmission resources are required.
