Description
AN-STM-1-ETH is designed as a STM-1 level optical modem with two 155.520Mb/s optical interfaces to provide a cost-effective and flexible multi-service platform. With 4 Ethernet interfaces compatible with IEEE 802.3/802.3u standard, it is easy to implement Ethernet transmission over SDH.
AN-STM-1-ETH supports port-based VLAN and IEEE 802.1Q tag-based VLAN. By adopting ITU-T G.7041, G.7042 and G.707-compliant EOS (Ethernet Over SDH) technology and VLAN technology, each Ethernet port can employs 1~4 separate Virtual Concatenation Groups (VCG), and each VCG can be assigned to one or more Ethernet ports. The bandwidth of VCG can be flexibly configured for efficient transmission of Ethernet data over SDH network.
AN-STM-1-ETH supports NE management based on CLI command and SmartView network management platform based on SNMP_V1 and SNMP_V2 protocol, to perform excellent management such as configurations, alarm monitoring and performance statistic.
AN-STM-1-ETH is suitable for data access network on the client side. With the technology compliant to ITU-T standards, it can communicate with products from other vendors adopting the same standards.
