32Voice+8E1+4FE (Physical Isolation) +4RS232 Fiber Multiplexer

This device provides 32-channel telephone, 8-channel E1 interface, 4-channel physically isolated Fast Ethernet interface (independent bandwidth per line speed 100M), and 4 expansion interfaces. The Ethernet interfaces are switch interfaces, which can support VLAN. 4 expansion interfaces can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 wire E&M audio signal, dry contact signal, and Ethernet signal (Bandwidth 2M). The SNMP or Console Management is optional.

● E1 interface complies with G.703, and adopts Full Digital Clock Recovery and Smooth Phase-Locked Loop (SPLL) technology;

●Voice interface support FXO/FXS, EM2/4 audio, Magnet Telephone Interface. The FXO port is connected to the PBX, while the FXS port is connected to the user’s telephone;

● Voice port supports caller ID display, reverse polarity charging, and fax function;

● It supports mutual dialing function between two stations;

● This device provides 4 extended interfaces, which can be used to expand 1-4 channels of asynchronous data transmission, such as RS232/RS485/RS422/TTL, or 1-8 channels of dry contact signals;

● The Ethernet interface has a bandwidth of 100Mbps and supports line speed 10/100M, full/half duplex auto-negotiation, as well as VLAN partitioning;

● The 4 100Mbps Ethernet interfaces can be used as switching ports and support VLAN partitioning. They can also be configured as 4 logical channels for network isolation;

● Ethernet interface can support AUTO-MDIX (crossed line and straightly connected line self-adaptable);

● The telephone interface is equipped with lightning protection that meets the GB/T17626.5 (IEC61000-4-5) standard for short-circuit current wave of 10/700μs, and can withstand a peak output voltage of 6KV under open circuit conditions;

● The transmission distance is up to 2-120Km without interruption;

● AC 220V, DC-48V, DC24V can be optional.
