2.2.3.1.36 LINEDIGITMODE_Constants
The LINEDIGITMODE_Constants are bit-flag constants that describe different types of inband digit generation.

Description |
|---|---|
|
LINEDIGITMODE_PULSE 0x00000001 |
Uses rotary pulse sequences to signal digits. Valid digits are 0 through 9. |
|
LINEDIGITMODE_DTMF 0x00000002 |
Uses DTMF tones to signal digits. Valid digits are 0 through 9, *, #, A, B, C, and D. |
|
LINEDIGITMODE_DTMFEND 0x00000004 |
Uses DTMF tones to signal digits and detect the down edges. Valid digits are 0 through 9, *, #, A, B, C, and D. |
A digit mode can be specified when generating or detecting digits. Note that pulse digits MUST be generated by making and breaking the local loop circuit. These pulses MUST be absorbed by the switch. The remote end merely observes this as a series of inband audio clicks. Detecting digits sent as pulses MUST also be able to detect sequences of 1 to 10 audible clicks.
