多E1协议转换器系列Multiple E1 Protocol Converter Series产品概述：Overview:多E1协议转换器系列实现传输为多路E1协议与V.35、以太网协议接口之间的功能转换；广泛应用于各大运营商及行业接入的高带宽需求场合，如路由器与E1接口的转换，或者以太网通过SDH等传输设备进行异地互联的场合；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.产品特点：Product Features:u 提供多种环回测试和伪随机码测试功能，使用环回功能时不会导致以太网瘫痪；同时具有外部E1物理环回自动检测功能；u 14 路E1 线路间允许最大传输时延差为32ms，保证能在各种复杂网络下的稳定可靠运行；u 每路E1提供1.92M带宽，共7.680M带宽。自动检测4 路E1 线路中可用通道数目，并自动分配带宽。在设备正常工作时，插拔任意一个E1线路，不会影响设备的正常工作；u 每路E1 支持误码在线检测功能，当某路E1误码率超过设置门限时，系统自动关断该路E1；u 支持以太网关断功能，当失效的E1路数超过设置门限时，系统自动关断以太网；u 提供4路交换式的以太网口，替用户省去一个以太网交换机；支持交叉/直通线自动识别；u 以太网口10M/半双工、10M/全双工、100M/半双工、100M/全双工、自适应可选，支持VLAN协议；u V.35用户接口速率可调，支持内、外、从三种时钟方式，满足各种应用环境；并且V.35接口可以工作于DTE和DCE方式；u 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; u The allowable maximum transmission time delay difference of 14 channels of E1 channel is 32 ms, which can ensure a stable and reliable operation in various complex networks;u 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; u 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; u 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;u 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.u Ethernet port can support 10M/semiduplex, 10M/full-duplex, 100M/semiduplex and 100M/full-duplex modes and adaptive mode (optional), and support VLAN;u 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. 典型应用：Typical applications产品规格：Product Specification:2E1-V.352路E1接口转V.35接口协议转换器，V.35接口支持4M带宽；2 channels of E1 -V.35 converter, and the V.35 port can support a bandwidth of 4M.4E1-V.354路E1接口转V.35接口协议转换器，V.35接口支持8M带宽；4 channels of E1 -V.35 converter, and the V.35 port can support a bandwidth of 8M.2E1-4ETH2路E1接口转4路交换式以太网接口协议转换器；以太网接口支持4M带宽；2 channels of E1 -4 channels of switched Ethernet ports protocol converter, and the Ethernet port can support a bandwidth of 4M.4E1-4ETH4路E1接口转4路交换式以太网接口协议转换器；以太网接口支持8M带宽；4 channels of E1 -4 channels of switched Ethernet ports protocol converter, and the Ethernet port can support a bandwidth of 8M.4E1-ETH4路E1接口转以太网接口协议转换器；以太网接口支持8M带宽；4 channels of E1 -Ethernet converter, and the Ethernet port can support a bandwidth of
