INFORMATION
Functions
The voice over fiber multiplexer is point to point fiber transmitting equipment, which realizes 1~8 channel voice (FXO, FXS) POTs phone over fiber and 4 E1,4*100M Ethernet, 4 channel RS232 for option. Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage.

FAQ:
Question: Can the Fiber Multiplexer be configured as 4Voice+4ETH+4RS232 with SNMP? If can, does the device have VLAN dip switch?
Answer: Yes, the Fiber Multiplexer can be configured as 4Voice+4ETH+4RS232 with SNMP. But the device doesn't have VLAN dip switch. VLAN cannot be set through SNMP, only can be set through console management.
