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
If you require additional tone receiver and transmission resources over and
above those provided on the SSC card, install an NTAK03 TDS/DTR card.
