Ensuring Premium Carrier Ethernet SLAs

While Lowering Costs

Several years ago, Metrotel, which began as a regional fiber optic ISP and wholesale provider, started offering basic Ethernet services using the technology available at that time, which meant media converters and Ethernet switches. As demand for services grew, customers expressed the need for greater bandwidth with the best possible SLAs, but the existing network was not equipped at that moment with the appropriate tools to meet these needs.

Reduces Maintenance Visits by 60% As part of its continuous research strategy, Metrotel turned to Konectra, an elite level RAD Solution Partner in Colombia, which proposed RAD Service Assured Access (SAA) solutions, based on the ETX family of IP and Carrier Ethernet demarcation and aggregation devices. Field tests with Metrotel confirmed that the ETX delivered the strict SLA guarantees requested by VIP wholesale customers. Moreover, the ETX lowers Metrotel’s technical support and maintenance costs while reducing customer churn. Tools like the RADview Performance Monitoring Portal, which displays actual Layer 2 and Layer 3 TWAMP metrics on an intuitive user interface, eliminated six out of ten monthly visits that the Metrotel support team would otherwise have had to make to each VIP customer.

Within a year, Metrotel had found that its operational and maintenance costs were significantly less than they had been under the old access model. Its OpEx savings more than paid for the cost of migrating all their VIP corporate customers using the ETX. In addition, new customers were quickly added using RAD’s MiNID, a miniature programmable network interface device (NID),available either as an SFP sleeve that plugs into any SFP port on existing networking equipment or in a standalone format.

Easy Interconnection with Other Carriers Using CE 2.0 Certification
At the same time, Konectra assisted Metrotel in obtaining Carrier Ethernet 2.0 certification, which enables it to meet Metro Ethernet Forum (MEF) recommendations using RAD’s CE 2.0-certified solutions. Certified engineers will then be able to design interconnection points (ENNI) with other providers and networks using RAD’s ETX-220A, a 10G Carrier Ethernet demarcation and aggregation device, and the ETX-5, RAD’s Ethernet service aggregation platform, which Metrotel also chose to deploy.

“Ethernet’s success can simultaneously be its challenge if you cannot deliver the QoE and meet the SLAs that you contracted with the customer,” explains Angelo Manotas, Networking Infrastructure Director at Metrotel. “And then you find a solution that shows you in green on a single screen that everything is under control and that all services are reaching all your customers – it’s quite literally a perfect solution,” he states. “RAD’s solution is comprised of building blocks like the ETX, MiNID and RADview, which you can add to your network step-by-step, ensuring the flexibility that all growing businesses require.”
