Overview

 16voice phone fiber multiplexer is point to point fiber
transmitting equipment, which is designed on large scale integrated circuit,
realizes 1~4 E1 circuit, 1~4channels 10/100/1000M Ethernet, 16 channel voice (FXO/FXS) and 1~2
channel RS232. Its merits include complete warning function, high integration,
low consumption, stable performance and convenient usage. In the 16channel
voices, the FXS and FXO can be combinated freely, for example,8*FXS+8*FXO.

FAQ:

Question1: Just to confirm again, can the voice phone fiber multiplexer equipment have the following specifications:
FXO Port
1. Ringing Voltage Range: -90V-140V rms
2. Voltage to AB Leg: Must be able to handle Exchange voltage of A-line -48V DC, B-line 0V DC.
FXS Port
Line Voltage A-B: -48V DC
Answer: Yes, the voice phone fiber multiplexer has the above specifications.

Question2: Is there VLAN dip switch built on the POTS telephone fiber multiplexer?
Answer: The fiber mux device has not DIP switch for VLAN setting. You configure the VLAN TAG by console management.

Question3: Can the FXS FXO over fibrt multiplexer be managed by SNMP?
Answer: Yes, the FXS/FXO fiber multiplexer support SNMP management.

Question4: 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.
