General description
Fibre Ethernet Access Device
The 1645 series of Ethernet Access Devices (EAD) offers service providers a cost-effective gigabit
Ethernet access solution and enables them to offer managed Ethernet services to their business cus-
tomers. As Ethernet Demarcation Device it is possible to monitor and control Ethernet services end-to-
end and to provide SLA reports. In addition to comprehensive layer-2 functionality the device also offers
a layer-3 router implementation which makes it an ideal choice to deliver carrier Ethernet, Internet and
IP services with one device. The equipment is interoperable with any standards-based carrier Ethernet
equipment and can be integrated into any existing management environment.
Fibre Access
The 1645 provides network operators the means to deliver advanced carrier Ethernet services to their
business customers at minimal cost. A Gigabit Ethernet Combo interface provides copper or fibre con-
nectivity to the rest of the carrier Ethernet infrastructure; a second Gigabit Ethernet Combo interface can
be provided, which can be used as backup of the first uplink. The 4-port GigE switch provides the inter-
face to the user applications.
Extensive Feature Set
At the heart of this platform is a high performance Ethernet switch/router incorporating advanced Layer
2 and Layer 3 forwarding, security and Quality of Service capabilities as standard. The software-based
switching and routing core offers a very high degree of flexibility when compared to hardware-based
designs in terms of features, software maintenance and upgrades.
Metro Ethernet Services
As a demarcation device the unit can deliver standard Ethernet services such as Ethernet Private Lines
(EPL), Ethernet Virtual Private Lines (EVPL) and Ethernet LAN services (ELAN). The 1645 fully com-
plies with the MEF.9 and MEF.14 requirements as defined by the Metro Ethernet Forum.
OAM Monitoring
Monitoring quality and availability of every dataflow as part of the carrier Ethernet service gives a clear
view on the status and the performance of the Ethernet service. The 1645 supports both point-to-point
OAM monitoring (IEEE 802.3ah) and end-to-end performance monitoring (IEEE 802.1ag & ITU-T
Y.1731) on all Ethernet interfaces.
