XLR 560 Ethernet First Mile (EFM) / Ethernet Extender Overview

The Case Communications XLR 560 Series extends the reach of Ethernet services to remote sites by using fibre optic circuits and / or bonded copper pairs. Designed with standards-based EFM technology (2Base-TL), the XLR560 series allows service providers and enterprises to deliver Ethernet with symmetrical bandwidth at rates up to 60Mbps over Copper using TCPAM 128, and up to 200Mbps Over dual fibre ports.

The XLR 560 is an extremely flexible product, and has the ability to be ‘daisy chained, or to have ‘split routing’  as can be seen from some of the application diagrams below.

XLR 560 Ethernet First Mile Application Examples

Point to Point Over 1 to 4 copper pairs

The XLR 560 series can be used as  a point to point Bridge / Ethernet Extender operating over 1 to 4 copper pairs of wire as shown below. Data Rates of over 15.3 Mbps can be achieved on each pair, with 4 pairs providing up to 60Mbps

Ethernet First Mile Local Loop Unbundling

Using the  Case Communications XLR5000 DSLAM  within the local telephone exchange, allows for Local Loop Unbundling. This provides a very cost effective solution with data rates up to 60Mbps over copper  using TCPAM 128 to each end user, and up to to 200Mbps to each end user over Fibre. The Case Communications XLR 5000 allows for Gigabit Back hauls.The diagram below shows sites connected via both copper and fibre to the XLR 5000 DSLAM

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 560 can bond up to 4 pairs, and deliver up to 60Mbps of Ethernet to users within the service area.

The XLR 560 operates mainly over a point-to-point configuration. It can be configured as either a COE or CPE device allowing one unit to operate in two modes.

Lower CAPEX and a quick return on investment

With a compact form factor and optimised for use over an existing copper network, the XLR 560 reduces the initial investment and deployment time in delivering higher speed Ethernet service. It provides low risk and a quick return on investment.

Comprehensive and easy OAM&P functions in provision and management

The XLR 560 implements the IEEE 802.3ah standard and a vendor extended management features. It enables users to significantly reduce operating expenses as its based on standard Ethernet technology and it eliminates major technology upgrades. The XLR 560 is compatible with any standard Fast Ethernet interface from switches, routers, and SONET / SDH equipment.

The fast Ethernet interface enables the XLR 560 to work as a smart Ethernet demarcation device as well, which is required between the customer interface (UNI) and provide separation between the carrier WAN and Enterprise LAN by monitoring network status and operation at the customers site.

Management

The XLR 560’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 560 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. The traffic management and QOS features enable services providers to offer value added services for minimal cost.
