The default is 10. SPA To PSTN Gain dB of digital gain (or attenuation if negative) to be applied to the signal sent from the SPA to the PSTN side. The range is -15 to 12. The default is 0. Ring Frequency Max Specify the higher limit of the ring frequency used to detect the ring signal. The default is 100. PSTN To SPA Gain dB of digital gain (or attenuation if negative) to be applied to the signal sent from the PSTN side to the SPA. The range is -15 to 12. The default is 0. Ring Validation Time Specify the minimum signal duration required by the Gateway for recognition as a ring signal. The default is 256 ms. Tip/Ring Voltage Adjust Choices are {3.1, 3.2, 3.35, 3.5}. The default is 3.5. Operational Loop Current Min Choices for mA are: {10, 12, 14, 16). The default is 10. On-Hook Speed Choose from {Less than 0.5ms, 3ms (ETSI), 26ms (Australia)}. The default is Less than 0.5ms. Current Limiting Enable Enable or disable current limiting. The default is no. Ring Frequency Min Minimum ring frequency to detect. The range is 5-100. The default is 10. Linksys ATA Administration Guide 155
