Architecture and Description of the E1 Recording System

Recording for the existing E1 line, the better way is high-resistance and double-line recording. The connection diagram is as follows:

e1 recording system_1


As shown, insert the High-resistance Box into the middle of the original E1 line, and connect one E1 interface PCM 2 to the Recording System (NC-AD300D or NC-AD300XD) to recording. The E1 interface PCM 0 is through PCM 1 in the High-resistance Box; PCM 2 is an E1 interface that isolated by High-resistance, it will not have any effect on the original signal. The Recording System send the recording data to the Recording Server by network interface, the recording data will be stored and managed by the recording server.



Function and Features
1- On-line recording

The mode for E1 channel recording: start the recording software, then the system automatically recording the E1.


2- Real-time monitoring

We can set a fixed E1 channel for monitoring, also can do the real-time monitoring for the current and arbitrary call. When monitoring, it will not affect the quality of recording , you can easily transfer to another call channel.


3- Management of the recording files 

The system can inquiry, compile statistic, delete, modify the recording, and other operations. Searching and back to listen to the recording data, it can be according to channel number, date, time, dialed phone number and other conditions to do the single and combined queries.


 4-System management

According to the request, the customer can increase and delete the system administrator, or modify the relevant permissions of the administrator, assign different permissions to different administrators. In summary, the user management is very easy.
