PSTN Line Tab Chapter 5 Linksys ATA Field Reference Field Ring Validation Time Tip/Ring Voltage Adjust Operational Loop Current Min On-Hook Speed Current Limiting Enable Ring Frequency Min Ring Frequency Max Ring Validation Time Ring Indication Delay Ring Timeout Ring Threshold Ringer Impedance Line-In-Use Voltage Description Specify the minimum signal duration required by the Gateway for recognition as a ring signal. The default is 256 ms. Choices are {3.1, 3.2, 3.35, 3.5}. The default is 3.5. Choices for mA are: {10, 12, 14, 16). The default is 10. Choose from {Less than 0.5ms, 3ms (ETSI), 26ms (Australia)}. The default is Less than 0.5ms. Enable or disable current limiting. The default is no. Minimum ring frequency to detect. The range is 5-100. The default is 10. Maximum ring frequency to detect. The range is 5-100. The default is 100. Choose from {100, 150, 200, 256, 384, 512, 640, 1024} (ms). The default is 256ms. Choose from {0, 512, 768, 1024, 1280, 1536, 1792} (ms). The default is 512ms. Choose from {0, 128, 256, 384, 512, 640, 768, 896, 1024, 1152, 1280, 1408, 1536, 1664, 1792, 1920} (ms). The default is 640 ms. Choose from {13.5-16.5, 19.35-2.65, 40.5-49.5} (Vrms). The default is 13.5-16.5 Vrms. Choose from {High, Synthesized(Poland, S.Africa, Slovenia)}. The default is high. Determines the voltage threshold at which the SPA-3000 assumes the PSTN is in use by another handset sharing the same line (and will declare PSTN gateway service not available to incoming VoIP callers). The default value is 40v. 5-64 Linksys IP Phone Administrator Guide Document Version 3.2
