More details

4 *FXO(S)/E&M Ethernet fiber optical PCM multiplexing,4 voices fiber PCM multiplexing:PCM-F04


This PCM-F04 point to point fiber transmitting equipment, which is designed on large scale integrated circuit, realizes 1 channel 10/100M Ethernet, 4 channel voice phone. Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage.


1.Have two row of LED , one indicate local status, the other indicate remote status
2.Based on self-copy right IC
4.Provide two clock mode, fiber main clock and fiber line clock
5.Have three LoopBack Mode: fiber interface LoopBack(ANA)、ETH LoopBack(DIG)、command the remote ETH LoopBack (REM)
6.Realize auto-speed setting of local device to remote device
7.Having pseudo random code test function, can used as a 2M Protocol Analyzer
8.Ethernet support N*64k rates, rate from 64k to 2048k.Ethernet data suggested function, real-time indicate data communication state
9.Provide 4 channels voice access, support calling indication
10.Voice port supports O port and S port, O port connect with PBX, S port connect with phone users
