# EUC non-editable parameters

The following NCC.X.ADI_EUC 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 | Type/ Unit | Default | Description
--- | --- | --- | ---
seizureacktime | ms | 10000 | Outbound: Specifies time to wait for seizure acknowledgment after seizing the line.
seizurewaittime | ms | 200 | Outbound: Specifies the time to wait to be seized on a two-way trunk, after the TCP seized the line.
answerwaittime | count | 90 | Outbound: Specifies the maximum time for the protocol to wait after the call accepted indication until the phone is answered (seconds).
acceptwaittime | ms | 20000 | Outbound: Specifies the maximum time for the protocol to wait after dialing before being notified that either the call has been accepted and the phone is ringing, or that the call has been rejected.
digitspilltime | ms | 20000 | Inbound: Specifies the total time the dialing process is allowed to take.
bitqualtime | ms | 20 | Specifies the qualification time for bit changes.
interdigitreceivetime | ms | 20000 | Inbound: While receiving decadic pulses, if the number of expected incoming digits is not known, this parameter specifies the time between two trains of pulses to conclude that the incoming dial string is finished.
winktime | ms | 150 | Inbound: Specifies the duration of an inbound wink. Depending on the target country, the wink has a different meaning and occurs at different phases of call setup.
toneontime | ms | 80 | Specifies the time a DTMF tone should be ON while dialing.
toneofftime | ms | 80 | Specifies the time a DTMF tone should be OFF while dialing.
pulseontime | ms | 50 | Specifies the time a pulse should be ON while dialing with decadic pulses.
pulseofftime | ms | 50 | Specifies the time a pulse should be OFF while dialing with decadic pulses.
hightoneamplitude | IDU | 352 | Specifies the amplitude of the higher frequency of the DTMF tones while dialing.
lowtoneamplitude | IDU | 440 | Specifies the amplitude of the lower frequency of the DTMF tones while dialing.
interdigitsendtime | ms | 700 | Outbound: Specifies the time between two trains of pulses while dialing with decadic pulses.
dialpulsemethod | mask | 0 | Determines the dialing type: 0 - DTMF dialing 1 - Decadic dialing
errorearlyanswer | mask | 0x0 | If this parameter is set to 1, an answer signal before all digits have been dialed is an error, and the TCP clears the call.
signalswep7in | mask | 0x0 | Configures protocol for inbound P7.
NMScountry | count | 25 (Italy) | Code for the target country.
mintimeconnected | ms | 200 | Inbound: The minimum time the TCP must remain in the connected state (in order to allow the switch to bill the call).
incomingqualtime | ms | 60 | Inbound: Signaling bits qualification time while playing ring tone (Italy only).
releaseguardtime | ms | 250 | Inbound: Minimum time the release guard signal must be on.
timewaitunblock | ms | 200 | Time the TCP waits after receiving the command to unblock the line, before actually doing it and going to idle.
timeinterdigit | ms | 400 | Inbound: Minimum time between trains of decadic pulses.
maxbillingpulse | time (ms) | 200 | Outbound: Maximum duration of billing pulse (for those protocols in which the line code of a billing pulse is the same as clear back).
maxdecadicpulse | time (ms) | 100 | Inbound: Maximum duration of decadic pulse (for those protocols in which the line code of a decadic pulse is the same as clear forward).
