E1 over Ethernet (FNTU761) series allows operator to provide Ethernet data traffic and TDM E1 services such as inter-office LAN connectivity, Internet access and secure virtual private networks (VPNs). This approach extends the service over fiber, facilitating management of differentiated services up to the customer premises while ensuring service level agreement (SLA) enforcement.
E1 over Ethernet (FNTU761) applies pseudo-wire technology that makes it possible to deliver E1 over IP, VPN, Ethernet networks. FNTU 761 supports transmission up to 4 x E1 links and 2 x Gigabit Ethernet links over a single optical fiber connection. With conformity to TDM over IP technology such as CESoPSN & SAToP, FNTU 761 is able to support both point-to-point and point-to-multipoint applications.
