690 Matrix PRASAR UCS System Manual
Tone standards vary with the country of application. For example, as per ITU standard, the Dial Tone for India
consists of 400Hz modulated by 25Hz, whereas it is 350+440Hz, without modulation, for USA/Canada. Further,
many countries use different frequencies and cadences for the same tone. For example, in the US, five different
frequency and cadence are used for Dial Tone.
PRASAR UCS offers the flexibility of setting the Call Progress Tone Generation (CPTG) type to match the country-
specific CPT standards established by ITU.
India being the default 'Region' for PRASAR UCS, the CTPG for India is set as default in the system.
