Overview
The device is to provide two E1 access 1 +1 backup protection 30 phone output .part of the device is whole digital circuit .the device is reliable low power consumption high integration small size Easy to install and maintain. Many telecom operators customers rent E1 line then they can use the device to open 30 telephone by the Rented E1 line so that the headquarters and the branch can communicate by phone freely.
Features
◆ based on independent intellectual property rights of integrated circuits;
