This device is a mini-sized equipment that provides 8 telephone outputs, with an optional configuration of 4 RS232 ports. The electrical components of the device are fully digital, ensuring reliable and stable operation. It has low power consumption, high integration, compact size, and is easy to install and maintain.
● It can monitor the alarm status of the remote end.
● The E1 interface complies with the G.703 recommendation and utilizes digital clock recovery and smooth phase-locking techniques.
● The voice interface supports FXO ports and FXS ports, EM2/4 audio interfaces. FXO ports connect to PBX systems, while FXS ports connect to users’ telephones.
● It supports 8 channels of voice access, including features such as caller ID and reverse polarity billing.
● It supports dialing between different sites.
● It can detect whether the remote device is powered off or the E1 connection is not working when an E1 signal is lost.
● It offers two clock modes: E1 primary clock and E1 line clock.
● It provides three loopback functions: ANA (Analog Network Analyzer), DIG (Digital Network Analyzer), and REM (Remote Network Analyzer).
● It has a pseudo-random code testing function (PATT), which facilitates line activation and can be used as an E1 bit error tester.
● It supports multiple power supply options: AC220V, DC-48V/DC24V, etc.
● The telephone interface is equipped with lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) standard for short-circuit current wave of 8/20μs and open-circuit peak output voltage of 6KV.
