This product offers 8 telephone lines and is highly versatile in its applications. The electrical component of the device consists of fully digital circuits, ensuring reliable and stable operation, low power consumption, high integration, compact size, and easy installation and maintenance.
● The device provides 8 voice access channels with support for caller ID display and reverse polarity billing function.
● It supports mutual number allocation among various sites.
● The E1 interface complies with the G.703 recommendation and adopts full digital clock recovery and smooth phase-locked loop technology.
● The voice interface supports FXO and FXS ports, where FXO ports are connected to the PBX and FXS ports are connected to users’ telephones.
● It can detect power loss or E1 failure on the opposite end when the E1 signal is lost, indicated by alarm lights.
● Multiple power supply options available: AC220V, DC-48V/DC24V, etc.
● DC-48V/DC24V power supply features automatic polarity detection, eliminating the need to distinguish between positive and negative poles during installation.
