MSW202 Ethernet Demarcation Device 802.3ah OAM Managed Switch

MSW202 Ethernet Demarcation Device

The MSW202 Ethernet Demarcation Device transports Gigabit Ethernet (GbE) traffic over fibre, enabling EPL (Ethernet Private Line) & EVPL (Ethernet Virtual Private Line) services with advanced carrier Ethernet features per MEF-9 and MEF-14 (Metro Ethernet Forum) specifications. Supporting link and service Ethernet OAM schemes, the MSW202 Ethernet Demarcation Device also provides extensive fault detection and diagnostic capabilities to ensure that actual network use complies with pre-agreed service level agreements (SLAs).

MSW202 Ethernet Demarcation Device application

First Mile Fibre Access: The EDD Series at the customer premises allows the operator to reach customers over fibre, while still using a standard Ethernet copper connection. Being part of the operator’s network allows the converter to act as a demarcation point between the operator and the customer.

Managed Carrier Ethernet Demarcation Device: The EDD Series is fully manageable over the fibre connection via 802.3ah, 802.1ag / Y.1731 from system status monitoring to provision configuration.

Cost - Effective: The EDD Series offers a rich management tool set to reduce operational expenses (OPEX) and scale management to large access networks. The EDD Series augments existing IP/SNMP-based management frameworks with the IEEE 802.3ah Operations, Administration and Maintenance (OAM) protocol, the IEEE 802.1ag Configuration Fault Management (CFM) protocol, Y.1731 performance management CPE WAN management protocol.
