Benefits of pre-programmed data

If the default numbering plan does not suit this system's needs, you can
change it using the procedures Chapter 22 of the Option 11C Planning and
Installation (553-3021-210) or Appendix A of the Option 11C Mini Planning
and Installation (553-3021-209).
There are three pre-programmed SDI ports on Option 11C and 11C Mini
systems. The NTDK20 SSC or NTDK97 MSC provides TTY ports 0, 1, and
2. All three SDI interfaces can be used as either modem or maintenance ports
for TTY terminals.
The SSC/MSC provides 30 channels of tone and cadence transmission to the
system.
The SSC/MSC also provides tone detection. Units 0-7 can be configured to
support DTR/XTD. Units 8-15 can also be configured to support DTR/XTD
Optionally, units 8-11 can be configured to support other tone detection
functions in lieu of DTR/XTD on units 8-15. These other tone functions
include one of MFC/MFE/MFK5/MFK6/MFR.
LD 56 contains default tables used for tone and cadence generation.

The main benefit of pre-programmed data is that it simplifies installation and
activation procedures. Table 5 compares how a task would be performed
using pre-programmed data and how it would be performed without pre-
programmed data.
