8Ch Telephone over fiber multiplexer with 1Ch Fast Ethernet
型号：LNK-PH08-E
►Voice port supports FXO and FXS port, EM2/4 audio interface
►Voice FXO/FXS access supports caller ID feature and reverse polarity billing functions
►Support various sites mutual number allocation function
►Ethernet interface supports 10M/100Mbps
Overview
LNK-PH08-E is a new generation 8-Ch FXO/FXS Telephone Fiber Mux. It can provide a 8-line voice interface and 1-line 10/100M Ethernet Interface directly upon the optical transmission. Voice Broadband Optical Multiplexer is mainly used in implementing connections between telephones and SPC exchanges through transmission network, as well as providing various kinds of data operation interfaces.
The device is widely used in: places such as telephone bars, middle and small scale companies, expressways and some temporary construction sites which demand quick solutions to the need of telephone and data operation, and the “Village-village Connection” telephone accessing project which is now in progress.
Features
►Voice port supports FXO and FXS port, EM2/4 audio interface, FXO port docking with program-controlled switchboard, FXS port connected to the user's telephone;
►Voice FXO/FXS access supports caller ID feature and reverse polarity billing functions
►Support various sites mutual number allocation function
►Provide 4 expansion interface, you can extend 1~8Channel asynchronous data, such as RS232/RS485/RS422/Manchester code; 1~8Channel voice, 1~8Channel switch or two/four line audio and so on
►Ethernet interface supports 10M/100M, half/full duplex auto- adaptable and VLAN
►Ethernet interface can support AUTO-MDIX (crossed line and straightly connected line self-adaptable )
►The transmission distance is up to 2-120Km without interruption
►The 4 U rack plug-in can be offered and support the SNMPA service.
►AC 220V, DC-48V, DC24V can be optional
►Data interface provide the lightning-protection function，which can reach the GB/T17626.5(IEC61000-4-5) (8/20μs), CM (6KV).
