 Marietta, GA/Ottawa, ON - April 17, 2012 - Optelian, a trusted international provider of optical transport systems, today announces Tier 1 carrier customer DWDM solution deployments to independent network operators, ATMC and Otelco.

ATMC and Otelco deployed Optelian’s DWDM solution, effectively obtaining mid-point interconnect applications with Tier 1 carriers. In both customer deployments, the Tier 1 carrier requirements called for routing new mobile backhaul services through the independent operators’ networks, but insufficient fiber capacity in those network links posed as a critical challenge.

“The ease of Optelian’s DWDM solution to both deploy and use was designed specifically for customers like ATMC and Otelco – enabling them to get up and running, address technical challenges, and be fully able to support their Tier 1 customers immediately,” comments Dave Mills, VP Sales, Service and Marketing, Optelian.

Optelian’s DWDM system enables the provisioning of the additional bandwidth and provides additional capacity for ATMC and Otelco’s future growth. Optelian’s DWDM solution also allows the network operators to install the standardized Tier 1 carrier system without requiring additional configuration, and enables seamless coordination with the Tier 1 to assign the correct wavelengths.

“We didn’t have previous experience with DWDM, but Optelian made this upgrade very simple for us to do,” states Rick Brock, Otelco Central Office Manager. “The equipment was straightforward to order as this is a widely deployed configuration, and Optelian assisted us with the installation, making the whole process very quick and easy.”

“We had already been using Optelian’s WDM and CWDM solutions, so we were able to install this on our own,” adds Jeff Stutts, Manager - Switch Services at ATMC. “Like all Optelian products, the DWDM equipment was delivered and installed quickly allowing us to get this link into service on our schedule.”

Creanord Ltd., a leading enabler of analytics-driven SLA management assisting Carriers and service providers in exploiting the flexibility of Ethernet to differentiate and save cost today announced the redefinition of 3G and LTE Backhaul SLA by leveraging MEF 10.2.1 based Unavailable Seconds (UAS) as well as the EchoVault solution with Red Hat Enterprise Linux.

The Metro Ethernet Forum Technical Specification Performance Attributes Amendment, MEF 10.2.1, defines the basic criteria for determining service availability. The service availability definition now uses frame loss during a sliding window to determine availability or unavailability for each short time interval. This can allow a CSP to define their service level specifications more appropriately, in the best case avoiding unnecessary SLA breach penalties. MEF 10.2.1 sliding window service availability calculations in EchoVault allow flexible SLA management, analytics and real-time and monthly SLA portal reporting all based on MEF 10.2.1.

CSPs increasingly need a flexible yet robust platform to support bringing innovative services to their customers. At the same time the pressure to leverage investments to the maximum never ceases. LTE puts significant delay and phase lock requirements on the networks and proper SLA management is required to ensure consistent performance even with high data rates and oversubscription.

The Metro Ethernet Forum has just announced the MEF 23.1 Multi-CoS Implementation Agreement (IA) for mobile backhaul via Carrier Ethernet, which the group claims can cut backhaul costs up to 25%.
 
As the name implies, the new IA enables cellcos to run multiple classes of service over their backhaul links.
 
That’s a big deal, according to MEF president Nan Chen, because with current Carrier Ethernet backhaul links (under MEF 22), most cellcos “have taken the simplistic step of building networks that treat all traffic the same and require a massive, costly and unnecessary overbuild of the network, without an accompanying revenue model to sustain the cost.”
 
While Carrier Ethernet is a cheaper and more scalable solution for backhaul than traditional E1s, those benefits eventually get canceled out as mobile data traffic starts approaching 4G levels and cellcos are forced to think beyond straight unlimited data plans.

Packet Synchronization over Carrier Ethernet Mobile Backhaul Networks
Mobile Backhaul refers to the network between Base Station sites and Network Controller/Gateway sites for all generations of Mobile Technologies. This document is based upon the MEF22.x Mobile Backhaul Implementation Agreement Technical Specification , which identifies the requirements for MEF Carrier Ethernet Services and MEF External Interfaces for use in Mobile Backhaul networks. Where possible, it specifies frequency and phase synchronization requirements for packet based synchronization methods and ITU-T Synchronous Ethernet (SyncE).

The Benefits of Multiple Classes of Service for Ethernet Mobile Backhaul
Historically, Mobile Operators obtained connectivity between their Cell Sites and their on-net Aggregation Sites primarily by leasing TDM circuits from third party Access Providers. Increasingly, Carrier Ethernet is the target solution for mobile backhaul with the Mobile Operator leasing Ethernet Virtual Connections from the Access Provider. Today, in the vast majority of cases, these EVCs are running a single Class of Service. While the use of Single-CoS EVCs is a way to get started, the MEF believes that the use of Multi-CoS EVCs for mobile backhaul is a much superior practice.

This paper compares Single CoS backhaul to Multi-CoS backhaul, concluding that Multi-CoS mobile backhaul results in substantial cost savings and that this lower cost Multi-CoS solution will result in equivalent or better quality than the Single-CoS solution.

Microwave Technologies for Carrier Ethernet Services
Customers increasingly want more bandwidth and better service quality to meet their application needs. Carrier Ethernet services are frequently the best selection to meet these requirements. This white paper provides an overview of how modern Microwave technology provides an efficient complement to copper and fiber in the access network.
