SS5 non-editable parameters

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.

Unit

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.
