PCM-F08:FXO/FXS E&M 8 channel voice ,E1 ethernet over fiber PCM multiplexer


8 channel voice over fiber PCM multiplexer

FXO/FXS E&M E1 Ethernet RS232 over fiber PCM multiplexer

More details


8 channel voice FXO/FXS E&M,E1 ethernet PCM multiplexer:PCM-F08

 

Function  

This point to point fiber transmitting equipment,which is designed on large scale integrated circuit,realizes 1-4E1 circuit,1 channel 10/100M Ethernet,1-8 channel voice phone and 1-4 channel RS232.Its merits include complete warning function,high integration,low consumption,stable performance and convenientusage.

For this device, we supply 2channels phones,4 channels 4wire E&M,1 channel E1,the other functions are invalid.

 

Features
