The present document specifies the Dual-tone Multi-Frequency (DTMF) signalling system.
The various parts of this multi-part deliverable provide a complete set of requirements for applications intending to useDTMF signalling.
The present document is intended to provide the level of detail that will enable manufacturers of telecommunicationsequipment incorporating DTMF signalling, to design the equipment such that it facilitates highly reliable signalling.This should not be taken to imply that any DTMF signalling system that fails to meet all the criteria described in thepresent document will not provide reliable signalling.
The present document is not intended to be used for the definition of regulated interfaces.
The present document covers the requirements for the DTMF transmitter and receiver for the case of DTMF signallingduring an established call from TE to TE.
