RAD Data Communications has introduced the ETX-1002, a 10-Gigabit Carrier Ethernet aggregation switch. The ETX-1002 provides a central aggregation solution for RAD’s ETX Carrier Ethernet demarcation devices installed at the customer premises and service endpoints, as well as third-party network termination units (NTUs).
The ETX-1002 is designed for deployment in 1-Gigabit and 10-Gigabit Ethernet access rings with sub-50ms switchover protection to provide high availability and service continuity when fiber cuts or link failures occur. Equipped with multi-priority traffic management capabilities and Ethernet OAM diagnostics, it ensures latency, jitter and packet delivery performance for Layer 2 VPN services and VoIP transport, as well as for broadband access, data center consolidation and mobile backhaul.
Meets Service Expectations of Enterprises, Operators and Service Providers
“Ten Gigabit Ethernet access and aggregation rings are key elements in making packet switched networks (PSNs) a true replacement for SDH/SONET transport and in defining carriers’ ability to meet the service expectations of enterprises, operators and service providers,” explains Ami Barayev, Product Line Manager at RAD Data Communications. “By connecting subscriber locations to newly deployed MPLS cores over scalable Carrier Ethernet fiber rings, telecom providers are able to optimize their networks for residential, business and wholesale services, as well as for mobile backhaul applications.”
The non-blocking edge switch grooms traffic from multiple locations using up to 24 Fast Ethernet or Gigabit Ethernet links, to deliver a variety of services over up to four 10-Gigabit Ethernet connections at wire speed. In addition to its fast ring protection features, the ETX-1002 supports mission-critical applications with link aggregation (LAG) redundancy and standard spanning-tree protocols.
Ensures Successful Migration to PSNs
“Many carriers and transport providers have already upgraded their aggregation and metro networks to packet switched technology in an effort to support next-generation services with ultra-high throughput at lower costs,” notes Barayev. “However, to ensure successful migration from legacy SDH/SONET transport to PSNs, telcos require Carrier Ethernet access and metro solutions that are capable of aggregating SLA-backed, QoS-differentiated services with the high level of resiliency and reliability that is needed for effective network and service control.”

Hybrid SDH/SONET and PSN Access Solutions Enable Seamless, Economical Migration to Next Generation Communications
RAD Data Communications has harnessed its expertise in TDM technology and leadership in Carrier Ethernet access to launch the AXCESS+ portfolio of CPEs (customer premises equipment) and central-site aggregation platforms. The portfolio combines extensive support for legacy services with future-proof Ethernet capabilities to address the challenges faced by carriers, mobile operators, utilities, and transportation networks in migrating to next-generation networks and services with flexibility, efficiency and carrier-class reliability.
“While many carriers and private operators are migrating their networks to packet technologies to lower costs and support IP-based services, there remains an enormous installed base of devices that use TDM, analog or low speed data connections,” notes Shoval Bolotin, Head of Product Management and Business Development for Multiservice Access Solutions at RAD Data Communications. “At the same time, the rapid introduction of Ethernet equipment has created a special challenge for network operators, who maintain extensive legacy TDM infrastructure and need to economically manage a myriad of interfaces, protocols, topologies, and media,” he adds. “AXCESS+ alleviates the CapEx and OpEx pains associated with the transformation to IP by simultaneously supporting multiple network generations. It also allows continuity for legacy services, while ensuring service quality and ultra-low latency for critical applications over new Ethernet, IP or MPLS networks.”
The AXCESS+ product lineup includes multiservice multiplexers and access nodes, fiber multiplexers, SHDSL Ethernet extenders, broadband wireless radios, and TDM pseudowire gateways. These are enhanced with a central-site platform for grooming, aggregation, cross-connect, or transparent delivery functionality. Supporting broadband access rates over copper DSL, PDH, SDH/SONET, fiber, or wireless media, the AXCESS+ devices provide system solutions with unified management.
Lowering Transition Costs and Ensuring Smart Communications over Packet
By lowering the number of network elements that need to be maintained and managed, AXCESS+ solutions eliminate the CapEx hikes and increased burden to network operations that are related to TDM and PSN co-existence. The hybrid access devices are also instrumental in reconciling required on-going investment in SDH/SONET equipment with long-term decommissioning plans, as they remain in place even after the network is replaced to packet technology. Furthermore, AXCESS+ is designed to provide SDH/SONET-level service assurance in a PSN (packet switched network) environment, including low end-to-end delay, high availability and resiliency, differentiated quality of service, and Ethernet OAM (Operations, Administration and Maintenance).
“AXCESS+ offers network engineers and purchasing managers the peace of mind that comes with durability, reliability and flexibility,” Bolotin emphasizes. “The AXCESS+ portfolio is comprised of standards-compliant solutions that deliver consistent and stable performance so as to require minimal on-site maintenance, yet are highly versatile to allow network operators the freedom to choose the migration path that best fits their needs,” he concludes.

Covage, a French “operator of operators” that enables local access operators and Internet service providers to deliver IP services to government and business customers, has selected the
ETX-201A Carrier Ethernet demarcation device from RAD Data Communications to offer wholesale broadband services to service providers, as well as deliver similar services directly to its own customers.
Covage currently has direct and indirect interests in 14 long-term network concession areas, allocated by the French government in exchange for a commitment to roll out FTTH connectivity to diverse government and business customers. The national transmission network that Covage has deployed utilizes 3,700 kilometers of dark fiber infrastructure to create a ringed network from Arras in the north to Montpellier in the south, serving 2,372 communities with over five million inhabitants, as well as almost 158,000 businesses of all sizes.
“To meet the needs of major operators throughout its network, Covage developed a Layer 2 Ethernet service that ensures flow-based, transparent delivery of customer data regardless of the protocols used and without changing the customer’s VLAN definitions,” states Norbert Blanchard, Director of Operations. “To implement the service, Covage required an Ethernet demarcation device with data rates up to 1 Gbps to mark the boundary between customer and operator networks,” he adds. While a number of competing devices were tested in its laboratory, Covage found that only RAD’s ETX was compatible with Covage strict technical requirements.
Moreover, Covage has recently deployed with success an Ethernet VPN for a major French service provider using RAD’s ETX-201A demarcation device. This Ethernet VPN is spread across three Covage network concession areas based in Burgundy – Creusot Montceau Networks, Grand Chalon Networks and 3CNET – and allows high bandwidth service capacity to 18 high schools.
“Working with RAD distributor FONEX, which was already a long term supplier to both Covage in France and Covage’s sister company Axia in Canada, made things happen smoothly,” concludes Blanchard. “FONEX helps up us in providing competitive yet adequate telecom solutions and services to our customers, in a very supportive way.”
Combines Added User Value with Quick RoI and Sustained Revenue
“Customers are embracing Carrier Ethernet services because they offer higher bandwidth, competitive pricing, flexibility, and scalability,” notes Sammy Elalouf, Sales Director at RAD Data Communications. “On their end, carriers and service providers see an opportunity to enhance their business networking solutions portfolios with Next Generation services that are cheaper to operate and that combine added user value with quick return on investment and sustainable revenue potential,” he explains. “RAD is helping lead the industry in developing the solutions required to make such advances possible.”

Company Wins Seven Major Tier 1 European Operator Deployments in 2009; Warns on Consumer Disappointment with LTE if Operators Don’t Solve Backhaul “Intelligence Crunch
RAD Data Communications today announced it has seen a major increase in demand for its backhaul solutions due to unprecedented mobile broadband usage. The company has scored backhaul equipment wins with 7 major tier-one European carriers in 2009 with several extending across numerous national markets. RAD has also outlined the nature of the LTE backhaul challenge which will require a significant intelligence shift to the cell-site to support the all-IP backhaul architecture.
RAD’s operator deployments include several of Europe’s earliest all-IP backhaul networks which required resolving the synchronization challenge – the single greatest obstacle to next generation backhaul deployments. All-IP networks are inherently unreliable for clock recovery or distribution and unless synchronization technologies are implemented, calls are dropped and hand-overs are fumbled.
