1. Product description
PW-FE1-4ETH Interface Converter 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,
PW-1E1-4ETH bridge realizes interconnection of four Ethernet by using
1pc 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 double Ethernet interface
broad band shared, MAC address self-learning, address filtering,
address table maintenance and flow control. The device has 4 ETH port,
it can work like an intelligent L2 switch. It can be reduce Net node,
dispense with device as HUB, consequently reduce the malfunction node.
Our PW-FE1-4ETH has the GUI NMS, it can manage the converter
like an intelligent L2 switch. It can set the TAG VLAN on these 4 ETH port,
can set the special tag like Q-in-Q, can configurable data rate from
32K~100M on each ETH port, can do some QoS setting.
E1 interfaces conforming to ITU-T G.703 and G.704 proposals are
provided at the end of WAN, 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=1to31). In Un-Framing Mode,E1 channel provides a rate of
2.048Mbps and accomplishes transparent transmission.

If the FE1-4ETH bridge is used in the framing mode, the
transmission clock can be either provided internally, i.e. using the main
clocking timing mode (INT), or extracted from the E1 channel, i.e. using
slave clock timing mode.
The FE1-4ETH bridge provides plenty of self-test functions,
supporting local loop. It also provides pseudo random code test function
to test error codes in the circuit.
It is proposed to use the products of this series in pairs.
A typical application is shown in figure 1.

●1st switch-SW0 (S1.1) is used to set E1 framing/non-framing.
―ON‖ refers to non-framing mode (2.048Mbps), despite of whatever
positions are set at other switches (S2,S3,S4).
●2nd to 32nd Switch (S1.2~S1.8, S2.1~S2.8, S3.1~S3.8, S4.1~S4.8)
SW1—SW31are respectively used to set 1st–31st time slots (this only
function if S1.1 is off).
Set at ―ON‖, the corresponding time slot is selected;
Set at ―OFF‖, the corresponding time slot is not selected.
The rate of E1 interface dependent on Number of Selected time slots.
For example: if 3rd switch (S1.3) is ―ON‖ and other switches is ―OFF‖
indicates that 2nd Time slot is selected, at this setting E1 rate is 64K;
If 7th(S1.7) & 10th(S2.2) switches is ―ON‖ and other switches is ―OFF‖
indicates that 6th& 9th Time slots are selected, E1 rate is 2*64K=128K.
SW-16 (S3.1) is used to set E1 frame structure to be PCM30(CAS
mode) or PCM31 (CSS mode)
‗0FF‘—PCM30, 16th time slot not being used for transmission service;
‗ON‘—PCM31, 16th time slot can be used for transmission service.

5.3 Configuration of Ethernet connecting devices
The equipment uses 100BASE-TX Ethernet interfaces and supports
adaptive 100M half/full duplex mode. Ethernet devices connected to
FE1-4ETH bridge (such as SWITCH, HUB, Ethernet adapter card (NIC),
etc.) can be set to 100M full duplex, 100M half duplex, adaptive 100M
half/full duplex and adaptive 10/100M.
5.4 Simple self-test methods for devices and E1 circuits
Test 1: test of back-to-back connection
Connect two FE1-4ETH bridge devices back to back, ping the other‘s IP
address on the two computers to test the two devices.
Test 2: test of E1 circuit transmission error codes.
Connect the device in the real operational environment, check the E1
circuit with the loop and pseudo-random sequence test function provided
by the device.
5.5 Typical applications
Mode 1: connect Ethernet with E1 networks.
SDH, PDH and DDN networks have already been widely adopted. With
E1 channels provide by such networks, bridging connection and
interconnection of two Ethernet networks at different locations can be
easily realized by FE1-4ETH bridge.
