● The device can monitor the alarm status of the remote end
● E1 interface complies with the G.703 recommendation and adopts fully digital clock recovery and smooth phase-locked technology.
● Voice interface supports FXO and FXS ports, EM2/4 audio interfaces, FXO port is connected to the PBX, and FXS port is connected to the user’s phone.
● The device provides 4 expansion interfaces, which can expand 1 Ethernet interface (bandwidth 2M), 1-4 asynchronous data such as RS232/RS485/RS422/Manchester code, etc.
● Ethernet interface rate is 10/100M, duplex/half duplex adaptive, and supports VLAN.
● It supports caller ID display and reverse polarity billing functions.
● It supports mutual dialing function among different sites.
● It can detect whether the remote device is turned off or the E1 is not connected when the E1 signal is lost.
● It provides 2 clock types: E1 master clock and E1 line clock
● It provides 3 loopback functions: E1 interface Loopback (ANA), Ethernet interface Loopback (DIG), Remote Ethernet interface Loopback (REM).
● The device has a pseudo-random code testing function (PATT), which is convenient for line commissioning and can be used as a single E1-bit error tester.
● E1 can support N * 64k (N = 1-32) rate, which means the rate is adjustable from 64K-2048K.
● Multiple power mode options: AC220V, DC-48V / DC24V and so on.
● Telephone interface with lightning protection, lightning reached IEC61000-4-5,Short circuit current wave 8/20μs,open-peak output voltage 6KV standards.
