There are millions of monitoring devices, including alarm panels, fire systems, PERS, 2-way voice alarm systems, and HVAC and power reporting systems built on legacy TDM or analog telecom networks. Many of these devices are failing as more carriers are upgrading to VoIP networks. In response to this problem, IPtelX has built an enhanced VoIP network, known as the Alarm Industry Signal Network (AISN), that simulates the quality and reliability of legacy TDM and analog networks. This innovation has allowed legacy monitoring devices to stay in service on newer technology.
