Overview
LNK-PH04 is a new generation 4-Ch Telephone Fiber Mux. It can provide a 4-line voice 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.
►Voice port supports FXO and FXS port, magnet phone 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
►The transmission distance is up to 2-120Kmwithout interruption
►Data interface provide the lightning-protection function which can reach the GB/T17626.5 (IEC61000-4-5) (8/20μs), CM (6KV).
