INFORMATION

Functions

This point to point fiber transmitting
equipment, which is designed on large scale integrated circuit, realizes 1~4 E1
circuit, 1 ~4 channels 100M Ethernet, 32 channel voice (FXO, FXS) and 1~4 channel RS232. The device support
two optical fiber port (1+1 protection). 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.
