# FGD non-editable parameters

The following NCC.X.ADI_FGD 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.

Field | Unit | Default | Description
--- | --- | --- | ---
IDdigitmask | mask | 0x28 | Determines which digits identify the ID field when they are received. The first digit must be 1. The second digit is extracted from this parameter. The mask is the following: FEDC|BA98|7654|321- 1000|0000|0010|1000
setupbitqualtime | ms | 50 | Bit signaling qualification time for on-hook to off-hook transitions.
permanentsignaltime | ms | 60000 | Maximum time for remote end to remain off hook when trunk is not in the conversation state before a permanent signal condition is detected. Valid range is 1-65535.
defaultrejecttone | integer | 2 | Default tone to play if the PC does not respond to an incoming call indication (see waitforPCtime): 0 - Ringing 1 - Busy 2 - Reorder (fast busy)
winktime | ms | 200 | For incoming calls, the duration of the generated wink. Set this to 0 for no wink. Set to 0xFFFF for 350+440 Hz dial tone to be generated.
prewinktime | ms | 100 | Delay after incoming seizure is detected and before the start of the wink.
wait1stdigittime | ms | 7000 | Maximum time to wait for the first incoming digit after the completion of the wink.
waitfordigittime | ms | 8000 | Maximum time to wait for each incoming digit after the first one.
winkwaittime | ms | 10000 | Maximum time to wait for the far end to wink for an outgoing call. Set this to 0 if no wink is expected.
maxwinktime | ms | 4900 | Maximum duration of a detected wink.
predialtime | ms | 70 | Delay to start of outgoing address signaling after end of wink is detected.
mfkpsttimeon | ms | 80 | Duration of tone on for MF, KP, and ST.
mfkpsttimeoff | ms | 80 | Duration of tone off for MF, KP, and ST.
mfkpstampl | IDU | 352 | Amplitude of dialed tones.
releaseguardtime | ms | 1000 | Minimum on-hook internal between calls.
preanswertime | ms | 100 | Delay after the application has commanded to answer, and before the answered signal is sent to the network. The FGD TCP does not play a ring tone when accepting a call, but a certain delay is necessary.
noresourcemask | integer | 0 | Mask that controls behavior when no resource is granted on inbound calls. 0 - No signaling; just send error 1 - Generate wink, then send error
customSTtones1 | mask | 0x0 | Send customized ST tones.
customSTtone2 | mask | 0x0 | Send customized ST tones.
customSTtone3 | mask | 0x0 | Send customized ST tones.
alarmsonqualtime | ms | 5000 | Determines the qualification time for trunk alarms (time to wait after the commencement of a trunk alarm before the TCP is notified).
alarmsoffqualtime | ms | 4000 | Determines the qualification time for trunk alarm end (time to wait after a trunk alarm state ended before the TCP is notified).

The following parameters are reserved for NMS internal use:

- alarmsonqualtime

- alarmsoffqualtime
