Telephone Emergency Notification System consists of the dedicated software that is installed on the server or PC and the hardware device connected in PSTN (Public Switched Telecommunications Network). You can use E1 stream switch / TDM Switch/ Signaling converter/ Terratel SIP/E1 Gateway as the hardware device.
The server/PC and switch are interconnected using Internet/Intranet.
E1 stream switch is connected to PSTN with 1 or 2 E1 links. When interacting with PSTN the switch can support one of the following signaling: SS7, EDSS1, R2D, 2ВСК. Connection can be established with the existing E1 stream inline. To do this the product provides for up to 4 E1.
Calling is performed simultaneously over 1 or 2 E1 links.
The product is connected to IP network over SIP and calling is performed simultaneously over 60 channels.
By using the data server settings the user of the system can promptly change the system operating scenario and voice parts that constitute the voice message.
Calling to subscribers of the configured calling list is performed upon the operator command or automatically at a certain time. When the subscriber is busy then there may be several attempts to connect to him/her with the preset delay.
The calling process is monitored in the real time and its results are saved in reports with specifying the call start time, message name and its result.
During the calling process the additional mode can be used that allows the subscriber to confirm that he/she actually listened to the message. The subscriber should listen to the message until it is over. When the subscriber does not reply or a stop listening to the message before it is over than he/she will be called again.
The results of all calls are saved in the report files and database.
