The following NCC.X.ADI_SS5 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. |

Type/ |
Default |
Description |
---|---|---|---|
Line signaling timers - during different phases of the protocol. |
|||
intersignaltime |
ms |
100 |
Minimum time between two line signals in the same direction. Must be kept for signal qualification reasons. |
longqualtime |
ms |
125 |
Qualification time of almost all signaling tones. A tone must be present on the line for at least this duration to be recognized. |
shortqualtime |
ms |
40 |
Qualification time of the seizure or proceed to send compelled signal. It is shorter to minimize the possibility of glare. |
connectqualtime |
ms |
1000 |
Qualification time during the connected phase of a call. It is longer to minimize the possibility of talkoff (voice being erroneously recognized as a line signal). |
glarewaittime |
ms |
850 |
Time to wait for the seizure signal to stop, if glare occurs. If an outbound protocol seizes the line by playing a seizure tone, and subsequently recognizes a tone on the line that is not the proceed-to-send tone, it must wait for this time for the other tone to stop. |
signalcompelledtime |
ms |
10000 |
First compelled signal maximum duration. |
ackcompelledtime |
ms |
4000 |
Acknowledgment compelled signal maximum duration. |
compelledtoneslevel |
IDU |
250 |
Amplitude of compelled line signaling tones. |
Register signaling timers for the inbound protocol |
|||
waitKPtime |
ms |
7000 |
Inbound: Max time to wait after seizure acknowledge for the KP start of dialing digit to arrive. |
waitdigittime |
ms |
8000 |
Inbound: Max time to wait for every next digit. |
Register signaling parameters for the outbound protocol |
|||
outdialdelay |
ms |
100 |
Outbound: Time to wait after receiving the proceed-to-send signal, before starting to dial. |
KPandSTontime |
ms |
100 |
Outbound: Duration of the KP and ST tones. |
MFtoneontime |
ms |
55 |
Outbound: Duration of MF tones. |
MFtoneofftime |
ms |
55 |
Outbound: Duration of silence between MF tones. |
MFtoneslevel |
IDU |
352 |
Outbound: Amplitude of MF tones. |
outboundguardtime |
ms |
300 |
Outbound: Time after an outbound call in which the TCP will not place another call. |
