4E1-2Eth protocol converter

4E1-2Eth protocol converter
Product Detailed
Converts signal between (1~4) E1 interface and Ethernet interface and transmits video, voice, data and so on with Max. Bandwidth

  4E1-2Eth Protocol Converter

1 Name and Function

Name: 4E1-2ETH

Function: 1) Converts signals between (1~4) E1 interface and Ethernet interface and transmits video, voice, data and so on with Max. Bandwidth 7.936Mb (4E1).

               2) Get the connected Mac adds. Continuously and determine whether frames can be forwarded or filtered according to MAC destination address of data frames

               3) Supports limitation setting of CRC error code for each E1 interface. When error code rate is beyond the limitation, the system can automatically isolate the E1 link.

               4) Local loop back function is available (Four E1 channels are looped together.)

2 Working Condition:

Power Supply:                            AC220V/DC-48V/DC24V

Power consumption (desktop) :             <5W

Power consumption (stander) :             <75W

Operating Temperature:                   0°C ~ 50°C

Storage Temperature:                     -40°C ~ +70°C

Relative Humidity:                            95%

Atmospheric pressure:                    70kpa ~ 106kpa

Desktop and rack style device have the same composition and function. Users can refit

The desktop style in the rack style according to requirement, vice versa.

NO CAUSTICITY GAS, NO DUST, NO MAGNETIC FIELD DISTURB

3 Parameter and index

Interface type:                          Ethernet

Rate:                                         n*(2.048Mbit/s±50ppm) (n=1~4)

E1 interface impedance:           75Ω(unbalanced)/120Ω(balanced)

Desktop dimension:                   218mm ×136mm × 44mm(length*width*height)

Two desk-type device which are placed side by side and inserted in suitable bracket

Onto side slots can be mounted on standard 19-inch rack

Rack dimension:         483mm*165mm*177mm (can be mounted on standard 19-inch rack)

4 Features

1) Voltage select: desktop supports both AC200V and DC -48V; mounting rack: AC200V or DC -48V can be available with heat backup and support mixed insertion different cards.

2) E1 channels (from channel 1 to channel 4) are used to transparently transmit data at 10M/100M.

3)supports vlan

4)Ethernet interface supports 5 kinds of setmode: 10MFDX, semiduplex, 100MFDX, 100M semi duplex and auto-negotiation.

5) When Ethernet data transmitted, frames are reordered in the E1 channel so as to assure frames’ order effectively and improve the transmission rate.

6) It allows that the max. Transmission difference of frames’ order between each two E1 channel can be 16 ms, which can assure it be used stably and reliably in each complicated network.

7) When transmitting Ethernet data, attenuation of bandwidth of each E1 channel is only 64kbps and the actual effective bandwidth is 1.984Mbps.

8) Check the available channel from channel 1 to channel 4 automatically and distribute bandwidth automatically.

9) Two Ethernet interfaces can be exchanged.

10) When a receiving direction of any E1 link receives alarms about LOS, AIS and LOF, the corresponding sending direction will not be influenced. So asymmetry transmission is materialized over E1 link.

11) Supports SNMP.
