The following NCC.X.ADI_R15 parameters are country or network specific and cannot be modified.
Caution: |
Most of the parameters that follow are signaling specific: changing their value invalidates any approval certificate for the used board and can cause the board to malfunction. These parameters are described here for reference purposes only. |

60 |
Delay before starting to play the forward and backward tones. |
Outbound timers |
|||
seizetime |
ms |
400 |
Maximum time to receive the seizure acknowledge. |
waitbacksignaltime |
ms |
4000 |

interdigittime |
ms |
750 |
Time between two trains of pulses while dialing with decadic pulses. |
confirmanswertime |
ms |
275 |
Timeout for differentiating answer versus ANI request that is the same line code but accompanied by a 500 Hz tone. |
Inbound timers |
|||
waitfrwdsignaltime |
ms |
350 |
Maximum time to receive a forward signal. |
waitfrwddeksignaltime |
ms |
40000 |
Maximum time to receive a decadic digit. |
inbinterdigittime |
ms |
400 |
Time to wait before deciding that a train of decadic pulses is over. |
Inbound ANI detector timers |
