Ethernet First Mile 2Base-TL Broadband

XLR 550A – G.SHDSLBis Broadband

The Case Communications eXtreme Line Rate 550A (XLR 550A) extends the reach of Ethernet Services to sites by using bonded copper pairs. Designed using EFM (Ethernet First Mile) Technology (2Base-TL), the Case Communications XLR 550A provides a cost effective solution for both service providers and enterprises to deliver Symmetrical Ethernet services up to 22.8Mbps.

G.SHDSLbis 22.8Mbps Broadband Bridge

XLR 554A Application Example

• 22.8 Mbps Ethernet over copper

• 5.7 Mbps per pair

• IEEE 802.3ah Compliant.

• Automatic Rate Adaption

Extended Ethernet services to sites using existing copper infrastructure

Service providers and Enterprises can offer symmetrical broadband connectivity for transparent Ethernet services, DSLAM backhaul, Wireless backhaul and other applications. By leveraging, existing copper services and using the unique EFM bonding technology, the XLR 550A can bond up to 4 pairs, and deliver between 1 and 22.8Mbps Ethernet services to users.

Comprehensive and easy OAM & P Functions in provision.

The XLR 550A implements the IEEE 802.3ah standards, as well as a vendor extended management feature based on IEEE 802.3ah.This enables users to significantly reduce operating expenses as its based on standard Ethernet technology and it eliminates major technology upgrades. The XLR 550A is compatible with any standard Fast Ethernet interface from switches, routers, and SONET / SDH equipment.

The Fast Ethernet interface also enables the XLR 550A to work as a smart Ethernet Demarcation Device (EDD), providing demarcation between the carriers WAN and the Enterprise LAN, by monitoring network status and operation at the customers site.

Management

The XLR 550A's management includes a comprehensive Command Line Interface (CLI), user-friendly GUI based Web Browser interface and SNMP and Telnet.

Future-proof Ethernet traffic management and QOS features

The XLR 550A provides future-proof features meeting Ethernet Quality of Service (QoS) and Class of Service (CoS) requirements by utilising 802.1q VLAN and DSCP capabilities, stacked VLAN (Q-in-Q), four levels of priority, traffic flow control and rate control. This traffic management and QoS features enable service providers to offer highly profitable and value added services
