RAD Data Communications (News - Alert), a manufacturer of high quality access and backhaul equipment for data communications and telecommunications applications, announced a 10-Gigabit Carrier Ethernet aggregation switch named ETX-1002.
“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,” according to Ami Barayev, product line manager at RAD Data Communications.
The ETX-1002, according to company officials, 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).
Designed for deployment in 1-Gigabit and 10-Gigabit Ethernet access rings with sub-50ms switchover protection, ETX-1002 provides high availability and service continuity when fiber cuts or link failures occur, company officials said.
The switch is provided with multi-priority traffic management capabilities and Ethernet OAM diagnostics. With these features, 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, according to company sources.
“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,” added Barayev.
ETX-1002 grooms traffic from multiple locations using up to 24 Fast Ethernet or Gigabit Ethernet links and enable telecom providers to deliver a variety of services over up to four 10-Gigabit Ethernet connections at wire speed.
The aggregation switch also supports mission-critical applications with link aggregation or “LAG” redundancy and standard spanning-tree protocols.
Carriers and transport providers are upgrading their aggregation and metro networks to packet switched technology so that they can support next-generation services with ultra-high throughput at lower costs.
However, to ensure successful migration from legacy SDH/SONET transport to PSN, 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, according to Barayev.
Recently RAD Data Communications announced its participation at Ethernet Expo. The company displayed its portfolio of MEF (News - Alert) certified Carrier Ethernet NIDs at the event, TMCnet reported.
