Gigabit Ethernet over STM-1 converter

1,Introduction The product of IDM GE-STM-1-CONV converter is designed for the conversion between gigabit Ethernet to STM-1 as intelligent converged network bridge, meeting the high-capacity Ethernet requirements in Private network. The product with maximum 63E1 access to the Gigabit Ethernet ,It can directly attach to the SDH network so that reduced the large quantity 2M interface and jumper in the engine room. 1 63 E1 can be arbitrarily divided according to the different bandwidth requirements. Each channel is composed of one E1 or multi-E1(4,8 or16),transmitting the Ethernet data transparently. The application of the product reduces the cost of network construction and maintenance for the operator, enhancing the ability of quickly access to the private network and ensuring that the point to point analytical capabilities, realizing the achievement of the monitor on the whole network. 2,Features 1) Provide two STM-1 optical interfaces with chain network and SDH self-healing ring 2) Provide two Gigabit Ethernet with electrical port and optical port 3) Mapping 63 E1in STM-1,and divided 63 E1 arbitrarily 4) Every channel can configure with one or more E1, Maximum support 63 remote converters with single E1or 15 remote converters with four E1 or 7 remote converters with eight E1 or 3 remote converters with sixteen E1 5) Maximum delay difference between frames is 64ms in E1 channel, ensuring reliability and stabilization in complicated network 6) Auto-negotiation bandwidth according to the number of E1 7) of bidirectional E1 serial number supported and application of E1 number supported 8) Compatible with various single network bridge and multi-E1 network bridge of different manufacturers in mixed network 9) Provide console and SNMP interface to realize the whole network management 10) Standard 1U chassis, DC or AC power optional. 3,Specification Optical interface ITEM PARAMETERS ITEM PARAMETERS speed155.520Mbps±4.6ppmAdaptorFC(SC optional)Standard ITU-T G.957/G.958Wavelength1310/1550nmNo-relaying transmission distance50kmMedium ITU-T G.652/G.653,single moduleSensitivityBetter than -36dBinterfaceS-1.1(L1.1, L1.2 optional)E1 interface ITEM PARAMETERS ITEM PARAMETERS Rate2.048MbpsCodeHDB3Comply withITU-T G.703 standardImpedance75Ω/120ΩFrame structurePCM30/31signalingInbound SignalingChannelsUp to 63Ethernet interface ITEM PARAMETERS ITEM PARAMETERS RateN×2.048Mbps,N=0 63DuplexFull/Half auto-negotiationWorking modeSupply auto-negotiation 10M/100M/1000M complied with IEEE802.3u.Default setting: auto-negotiation.
