4Ch Telephone over fiber multiplexer with 1Ch Fast Ethernet
型号：LNK-PH04-E
►Support various sites mutual number allocation function
►Ethernet interface supports 10M/100M
Overview
LNK-PH04-E is a new generation 4-Ch Telephone Fiber Mux. It can provide a 4-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 1~4Channel asynchronous data, such as
RS232/RS485/RS422/Manchester code; 1~4Channel 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).
