QL-MSAP 1030 Multi-service Optical Access Platform

1.1 Overview
QL-MSAP 1030 is designed as a STM-1 level optical terminal with two 155.520Mb/s optical interfaces to provide an ultra-compact, cost-effective and flexible multi-service platform. It can realize the E1(up to 8E1), V.35, PCM traffic and 100Mbps Ethernet transmission over optical line.
QL-MSAP 1030 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.
QL-MSAP 1030 supports NE management based on CLI command and RayView network management platform based on SNMP_V1 and SNMP_V2 protocol, to perform excellent management such as configurations, alarm monitoring and performance statistic.
QL-MSAP 1030 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.
