The equipment converts and transports upto 4 x Ethernet links over an E1 in a shared* mode, or a discrete** mode, depending on the user's preference and selection.*In shared mode: All 4 Ethernet channels are transported over the same shared E1 link and areallowed full access to each other's path. The usermay select this mode if the user desires that all of the 4 x Ethernet links that are being transported over the same E1 to optimally share its bandwidth resources and where discretion is essential.*In discrete mode: All 4 Ethernet channels are transported over the same E1 link, but without allowing intrusion or access to each other's path. The user may select the discrete* mode when the user desires to transport all 4 Ethernet channels over the same E1 line discretely, and without allowing access to each other.The equipment shall always be installed and used in pairs, with one terminal being installed at either end (each side) of the network.The VCL-4 Ethernet over 1E1, 4*10(100)Base-T to E1 Interface Converter is an ethernet extension device utilizing TDM telecom infrastructure (the telecom network of E1s, or of PDH, SDH and E1/E3/SDH microwave etc. carrying E1s).The VCL-4 Ethernet over 1E1, 4*10(100)Base-T to E1 Interface Converter converts the Ethernet Data into E1 frame format for transmission over the existing TDM (E1) links and then re-converts the E1s back into Ethernet Data at the far-end terminal. It function is to primarily provide a BRIDGE between two Ethernet LANs over the existing E1 based telecom network. The device can effectively utilize the redundant bandwidth of telecom operators' existing TDM network to transport Ethernet data with low investment.*Optional powers 220V AC and -48V DC. May be ordered with either power option.DescriptionApplicationsThis equipment may be used for the following purposes:1.Bridging Ethernet LANs over existing TDM (E1) telecom network. Extending Ethernet Networks utilizing TDM (E1) landline based telecom infrastructure.2.Using telecom network of E1s / PDH / SDH Microwave etc. carrying E1s to transport Ethernet Data.In all these cases the equipment be always installed and used in pairs, with one terminal beinginstalled at either end (each side) of the network.VCL-4 Ethernet over 1E1VCL-4 Ethernet over 1E1Description and ApplicationsShared link modeIn the "shared link mode", each LAN can view and talk to other LANs. Example: each LAN can view and talk to all other LANs at same site or the corresponding remote side. This mode may be selected for use if bandwidth optimization and usage is of prime importance and the user is not averse to sharing the E1 link resources with the other LANs being transported on the same E1 link.For example all four Ethernet Ports at local site are in LAN Mode and will also communicate to all four Ethernet Ports at far end site.T ypical ApplicationNote:In the "shared link mode", the VLAN switch must be OFF (The ethernet ports are notisolated to each other on both sides of the E1 link).Note: Each DIP Switch is ON in downside and OFF in upside.POWERConverter in V LAN Mode “shared link mode”E1NetworkE1Network E1E1VCL-4 Ethernet over E1VCL-4 Ethernet over E1VCL-4 Ethernet over 1E1T ypical ApplicationPOWERDiscrete link modeIn the "discrete link mode" each LAN is bridged to, and can only talk to its corresponding LAN on the remote side. It can not talk to any other LAN either at same side or the remote side. This mode may be selected for use if the users do not wish to share the E1 link resources with the other LANs being transported on the same E1 link.For example the Ethernet Port 1 (at local site) will communicate to Ethernet Port 1 at far end site and so on for Port 2 etc.Example: In the discrete link mode , the LAN 1 (Ethernet Port 1 of the equipment) only can talk to the corresponding LAN 1 (Ethernet Port 1 of the equipment) at remote side and can not talk to any other LAN, either on remote side or same side.Note: In the discrete link mode , the VLAN switch must be ON (Ethernet Ports isolated) in Boththe units.Note: Each DIP Switch is ON in downside and OFF in Upside.Converter in “discrete link mode”E1NetworkE1Network E1E1VCL-4 Ethernet over E1VCL-4 Ethernet over E1VCL-4 Ethernet over 1E1Discrete Link ModeVCL-4 Ethernet over 1E1Technical features T echnical Features1.The maximum transmission rate of 4 Ethernet data over E1 links is2.048 Mbit/s2.Supporting 1600 long frames, accordance with Interior Switching Link (ISL) Protocol3Supporting local E1 port loop-back4.The Ethernet Port is self-adaptive to crossover or Straight/Parallel cable to avoid the trouble of re-wiring5.Supports up to four Ethernet Ports.

Please check with the E1 Cable.2T rouble: E1SYL light ONCheck point: Make E1 loop-back at E1 input port and output port, if the light OFF, thenhighlight the check on the opposite-end interface converter to see whether set to framingservice mode. If the opposite side interface converter has been set to framing service mode,check the transmission path of E1 for any disconnect. The alarm is valid if port is working on framing mode.3.T rouble: AIS light ONCheck point: normally this fault is due to either of the following reasons:1. The opposite-end E1 equipment cuts off receiving.2. There are other devices working under test on E1 transmission line.3. E1 Channel is in loop-back state.VCL-4 Ethernet over 1E1General Parameters 4.T rouble: LINK light OFFCheck point: This fault is basically due to the error in making network (crossover orstraight-through) cable. Please check if the equipment I require crossover cable or straight-through cable you are connecting to. VCL-4 Ethernet over E1 is self-adaptive to crossover or straight-through cable.5.T rouble: LINK light in normal state, but data PING failsCheck point:1. Check whether the state of the equipment Ethernet is in accordance with thatof the opposite-end Ethernet; If not then, cancel the self-adaptive state ofEthernet Interface and change compulsorily to configure speed and duplexso as to be in accordance with the other end.2. Check whether the equipment E1 port or E1 transmission channel is underloop-back or other test conditions, if any, then cancel it.3. Check whether the time slot configuration of the local equipment is inaccordance with the remote one. If not then, configure it to be in accordance.6.T rouble: Data succeed in PING, but with frame lossCheck point: This fault may be due to the following reasons:1. Incompatible configuration of E1 port impedance.2. Incomplete physical connection of E1 port, e.g. only one pole connected atreceiving end.3. Wrong configuration of clock, change the clock to master clock.7.T rouble: The communication is normal prior to configure port mask, but blocked after portmask configuration.Check point: Ensure whether the remote equipment also configured port mask, whether the port mask configuration at two ends is in accordance; after port mask configuration, onlyEthernet of same port number can perform communications. Check whether VLAN switch set to OFF (shared link mode is ON) the equipment connected to Ethernet interface, if any, T oggle the VLAN switch to ON (set the equipment for discrete link mode).General1.Power SupplyAC Mains Input : 220V 20% (AC Mains input model).*Optional powers 220V AC and -48V DC.

接口转换器
引言
为确保来自不同国度不同生产厂家的设备之间能实现
无障碍通信，国际标准化组织（itu-t）作了卓有成效的工作。

但遗憾的是，各种通信网络如计算机通信网（lan或wan）、传统电信网（pstn）等，由于发展的时期及背景的不同，产生了众多的标准。

例如：g.703、V.35、x.21、V.36、Rs-422和Rs-530等都用于高速通信。

虽然在功能上差异甚微，但它们却有着不同的电气和物理特性。

现存接口标准的差异妨碍直接通信，故要求设备之间有一中间设备完成接口转换。

该系列产品是针对这一实际问题而设计的，系列中所包含的多种多样的转换器能通过在不同接口间提供转换来克服上
述矛盾。

根据应用需要，转换形式可包括下列的一种或多种：
1.电气的-转换信号电平
2.物理的-提供不同型式的插头
3.功能的-转换信号的功能
4.速率的-从一种数据速率转换成另外一种
一、功能及适用
¤
¤10/100base-t以太网口与g.703的接口电气上的转换。

是一种高性能、自适应式远程以太网桥。

它体积小、成本低，很适宜对成本敏感的桥接应用，或作为比特流基础结构上的局域网延伸器或分段器。

¤作为延伸器或分段器应用时，有过滤和禁止过滤两种工作状态，以决定是否让所有通信量可在广域网线路上传送。
