256 Voice(FXS/FXO) over Fiber phone over fiber multiplexer

DESCRIPTION:   

BD-OP-MUX256  is a multi-service fiber multiplexer which can realize 256channel voice  and 4*10/100/1000M Gigabit ethernet over fiber transmission.The fiber  multiplexer is rack mount device which have 16slots for 16voice card or  E1 card.The device support SNMP andconsole management.

Features：

?        Based on the integrated circuit intellectual property rights;

?        Plug-in  design, convenient way to replace the question, to avoid the integral  equipment 1 telephone problems are needed to replace the problem;

?        Convenient expansion, increase the board can, convenient maintenance, replacement card;

?        The  equipment for 4U 19 inch machine frame, a total of a port plate and 4  16 telephone board, light board provides 4 fast / Gigabit Ethernet  interface and an optical interface +2 business interface such as  RS232/RS485/RS422 asynchronous data, switching signal, each plate can be  inserted network management board, 16 FXO/FXS plate, 8 EM2/4 board, E1  interface board, 8 serial data plate....;

?        This device is configured to route 256, if the user to expansion in 60 basis, only need to increase the phone card can be;

?        60 speech, support caller ID function and reverse polarity charging function;

?        Each site each schedule function;

?        4 Ethernet interface options for exchange, also can be divided into VLAN;

?        Ethernet interface for fast/Gigabit rate or optional, full duplex or half duplex adaptive;

?        Have a view displays the working status of remote device in the end;

?        Can choose various power: AC220V, DC-48V/DC24V etc.;

?        The telephone interface with lightning protection, lightning protection up to GB/T17626.5 (IEC61000-4-5) 8/20 μ s short-circuit current, open-circuit peak output voltage of 6KV standard.

Question: Regarding  to power supply, do we have any restriction to use DC or AC module in subscriber  side or office side?

Answer:the 256 POTs fiber multiplexer FXO side can use AC or DC power,both of them are ok;but for  FXS side,DC is ok.if you use AC power,you need combine  the adator we sent to  you.

Can  we use one AC + one DC at both sides? 

yes,no  problem

Are  these hot standby and load sharing?
