R15 non-editable parameters

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.

Inbound timers

waitfrwdsignaltime

ms

350

Maximum time to receive a forward signal.

waitfrwddeksignaltime

ms

tonedelaytime

ms

230

Delay between signaling answer during the ANI request and sending the 500 Hz tone.

This value has been optimized for use within the Russian network. It should be decreased for back-to-back testing.
