ASSIA DSL Expresse 2.7 Supports 100-Mbps VDSL
By Gary Kim
ASSIA DSL Expresse 2.7, a new version of the company’s software for optimizing the performance of DSL networks, is seen as a major first step toward allowing service providers to use fixed networks. These networks support networks offering access at 100 megabits per second using vectored very-high-bitrate digital subscriber line (VDSL) services, expected to see accelerated deployments in 2012 and 2013.
ASSIA Expresse 2.7 is the first product to offer advanced network management software for multi-tenant environments, where carriers must, or want to offer wholesale customers unbundled loops.
The latest version of the software includes support for identifying noise and interference issues that are more challenging compared to slower-speed DSL versions, helping service providers better identify issues that are dynamic, and vary by time of day, seasons of the year and subscriber behavior.
A recurring problem is “missing microfilters,” and the software allows for the detection of those conditions.
The latest version 2.7 also allows service providers to optimize performance, line by line, for latency performance, speed or throughput over time. Additional support for real-time optimization is also a new feature, according to Jerome Joanny, ASSIA senior director.
Although much of the demand can be expected to come from service providers in Europe and Latin America, higher-speed VDSL will likely be an important tool for North American operators, as many executives believe the business case for additional fiber-to-home or fiber-to-neighborhood upgrades is difficult.
That means a continuing reliance on faster copper-based access.
DSL and next-generation VDSL boast 70 percent of the consumer broadband line market share worldwide, according to Point Topic.
DSL and VDSL also added a whopping 50 million lines from Q3 2010 through Q3 2011, while cable and fiber to the home (FTTH) increased by only 10 million and three million lines, respectively.
The promise of FTTH is still largely a promise, with only 2.5 percent of access lines worldwide, due to the high cost of deploying fiber, according to Steve Timmerman, ASSIA SVP.
Wideband telco services subscribers are forecast to rise to 281 million in 2014, expanding at 30.9 percent per year from 73 million in 2009. ADSL subscribers will grow at only 8.4 percent per year during the same period, reaching 458 million in 2014, up from 305 million in 2009, a 2010 forecast by iSuppli Corp. suggests.
More recently, iSuppli has suggested that VDSL deployments might represent about six percent of new installations. Among technologies, asymmetric digital subscriber line (ADSL) continues to account for more than half of all net additions in the world with 51 percent share, driven by demand in developing regions, particularly China and Latin America, iSuppli says.
The combined market share of fiber technologies came in second with about 34 percent of the market, followed by cable modems at nine percent and VDSL at six percent.
