FE1-nEth*nVO*RS232

1: Introduction            

Type  FE1-nEth*nVo*RS232

Function  

1)        E1 interface is used as uplink interface

2)        Ethernet interface is used as data interface.

High performance, self-learning remote Ethernet bridge. Small size , low cost and as a bridging application suitable for cost sensitiveness also as a LAN stretcher. The unit can uninterruptible learn MAC destination address of the connecting LAN and determine whether frames can be forwarded or filtered according to MAC destination address of data frames .

3)           8 Voice interfaces are available with revised polarity charging and calling display       functions

4)           Automatic timeslot assignment. When voice interfaces dont work, the redundant timeslots are assigned to Ethernet interface.

5)           Asynchronous RS232 data channel can be used in the end terminal transmission.
