1. Realize Impedance multiplexing applications in digital E1 repeater cable, get all the call information and the audio signal on that cable.
2. Receive the Call and caller's information.
3. Single card with 2 / 4 Hi-Z input multiplexer, monitor 1 / 2 E1 interface up and down line signal.
4. Using an uploaded signaling analysis and processing module, the flexibility to configure the use of No. 1 signaling, ISDN or SS7 signaling protocols, enabling the different E1 relay a call signaling system state analysis and voice Signal Analysis
5. Recording AGC (Auto Gain Control) function.
6. Standard or custom of the DTMF signal / single audio signal detection, talk / Mute Detection
7. Use of CT-BUS, line with H.100 standard, easily supports this standard to interconnect to any third party board, which will access the exchange of voice signals to other devices.
8. Cards are equipped with lightning protection circuits to telecommunications standards to ensure against lightning damage.
9. Authorization number recognition with hardware circuit, every card with a unique hardware serial number, the user may be unique to the company to apply for the authorization number, software security to protect users
