1. Product description
FE1/100BASE-TX Interface Converter (also as
FE1/100BASE-TX Ethernet Bridge) is an Ethernet bridge of
high performance, which accomplishes the converting
between the 100M Ethernet port and the E1 port. As an
extended device of the Ethernet, the FE1/100BASE-TX
bridge realizes interconnection of two Ethernet by using the
E1 channel provided by existing networks with low cost.
100BASE-TX (RJ45) interfaces are provided at the
end of Ethernet LAN to accomplish various functions
including MAC address self-learning, address filtering,
address table maintenance and flow control.
E1 interfaces conforming to ITU-T G.703 and G.704
proposals are provided at the end ofWAN, supporting RJ45
and BNC connection modes. The E1 ports support both
framing and un-framing architecture. The user can select
an operating mode for the E1 interface according to the
connected E1 environment. This provides flexibility of
network application. In the framing mode, the E1 interface
provides a rate of N*64Kbps（N=1~31）. In the un-framing
mode, the E1 channel provides a rate of 2.048Mbps and
accomplishes transparent transmission.
