4E1 to Ethernet protocol converter

Specifications

4E1 to Ethernet protocol converter

Overview:

Multiple E1 protocol converter series can implement the conversion between multiple E1 protocol and V.35/Ethernet; it can be extensively used for operators and industrial access requiring high bandwidth, such as conversion between router and E1 interface, or the occasion where Ethernet are interconnected at separated net sites by SDH or other transmission equipment.

Product Features:

1. It can provide functions of multiple loop-back testing and pseudo-random code testing; the usage of loopback function will not result in the meltdown of Ethernet; it can also provide external E1 physical loop-back automatic detection function;
2. The allowable maximum transmission time delay difference of 1~4 channels of E1 channel is 32 ms, which can ensure a stable and reliable operation in various complex networks;
3. Each E1 can provide 1.92M bandwidth and the total bandwidth is 7.680M. The available channel number out of 4 channels of E1 ports can be automatically detected, and bandwidth can be distributed automatically. When the equipment is in normal operation, any E1 channel can be inserted or removed without influence on the normal operation of the equipment;
4. Each E1 can support online error code detection function, and when error code rate of any E1 channel exceeds the specified threshold, the system will switch off the E1 channel automatically;
5. It can support switch-off function of Ethernet, and when failed E1 channel number exceeds the specified threshold, the system will switch off the Ethernet automatically;
6. It is provided with 4 channels of switched Ethernet ports, saving one Ethernet exchanger for user; it is adaptive for crossover cable and straight cable.
7. Ethernet port can support 10M/semiduplex, 10M/full-duplex, 100M/semiduplex and 100M/full-duplex modes and adaptive mode (optional), and support VLAN;
8. V.35 user interface can support adjustable rate, and can support internal, external and slave clock modes, so as to be adapted to various application conditions; and it can work under DTE and DCE modes.
