Appendix B: Nyquist DTMF Feature Dialing Codes
Most features of the Nyquist system can be accessed via DTMF dial codes entered from a station’s keypad. The availability of a particular
feature dial code is determined and restricted by the DTMF code’s required CoS and the station’s CoS assignments.
For a list of alternatives to some of the DTMF codes listed here (e.g., codes that do not use the pound/hashtag symbol, #), see “Alternate
Dialing Codes” on page 144.
Note: DTMF codes marked with
a
support terminating the DTMF code with a # symbol to avoid the 5-second delay while the DISA appli-
cation waits for additional digits to be entered.
