Replacing Customer Edge Routers with Managed Ethernet Converters
Managed Ethernet Services over PDH and SDH
Carriers and service providers
Extending Ethernet service reach
Where fiber is not available, some carriers and service providers use a combination of Ethernet radios and customer edge routers to extend their Ethernet service offering to enterprises. These routers are used to access the SDH transport network. Where a large number of remote locations need to be served, however, the high CapEx associated with costly routers is prohibitive, hindering new revenue opportunities from Ethernet business services.
RAD Data Communications offers an economical alternative that eliminates the need for routers with managed Ethernet over PDH/SDH solutions that combine great savings with carrier-grade performance.
Eliminates the Need for CE Routers
Instead of routers, carriers are deploying the RIC-LC managed Ethernet converters in remote POPs, to backhaul Fast Ethernet user traffic received from the microwave radios and to prepare it for transmission over an SDH backbone using NG-PDH/SDH encapsulation and bonding, thereby allowing carriers to make use of their existing TDM infrastructure. RAD's Egate-100 Gigabit Ethernet over TDM aggregation gateways are deployed in a central location to aggregate Ethernet user traffic received from a large number of remote RIC devices. Together with the RADview-EMS management system, the RIC-LC CPEs and Egate-100 aggregators provide a complete access solution from the service provider central site to the customer premises.
The RIC-LC enables extension of high capacity Ethernet services to remote locations, by bonding up to 16 E1 links, thus providing scalable bandwidth from 2 Mbps to 8 Mbps to each customer.
At the central POP, the Egate-100 aggregates user Ethernet traffic and radio management data for delivery to the packet network and data communication network (DCN), respectively.

Remote, carrier-class management
Supporting VLAN-aware bridging and VLAN stacking (Q-in-Q), the devices’ Ethernet capabilities also allow prioritized quality of service (QoS) for various voice and data traffic, with traffic management attributes, such as scheduling and rate limitation. In addition, the Egate-100 and RIC-LC are remotely configured and monitored by the RADview EMS carrierclass element management system, which offers a variety of FCAPS (Fault, Configuration, Administration, Performance, and Security) and diagnostic tools to simplify operations and ensure timely fault notification.
