New Bonding Technology Improves Performance

To stretch their investments in copper, network operators have been using digital subscriber line (DSL) systems to bond multiple copper pairs into a single high-speed connection. The problem with traditional DSL bonding is that there is often cross-interference between loops, which impacts transmission speed. Loop qualification times and the low reliability inherent in single DSL lines also increase when lines are bonded. A new DSL technology called MIMO on DMT (multiple input multiple output on discrete multi tone) is different from traditional bonding in that it works at the physical layer to join the copper pairs. The Aktino bonded copper solutions provide transmission speeds up to 50+ Mbps using just 8 copper pairs.

Installing Fiber in MDUs Gets Easier

With nearly one-third of all U.S. households residing in multiple dwelling units (MDUs), network operators are faced with a significant challenge when it comes to equipping those residences with fiber. It’s tough to deploy fiber in MDUs because there are few places to hide the conduit. Technicians often must install fiber through ductwork or along walls and then hide it with molding. That means the fiber must be able to bend more tightly than fiber going into a green-field subdivision. In this white paper, ADC explains how reduced bend radius fiber products can help operators install fiber in shared residential structures without increasing attenuation of the fiber.

Ensuring Service in a Brave New IP World

The highly reliable public-switched voice network with its centralized switches serving thousands of subscribers is being replaced today by a distributed network of powerful mulit-service access platforms (MSAPs) and Internet Protocol (IP) transport devices. In the new network, thousands of subscribers may be served from a single MSAP, which may not have the built-in redundancy of a Class 5 switch. This fundamental change in network architecture could leave homes and businesses without communication services, including 911 service, in the event of a network outage. In this article, Steven Bruny, CEO of Aztek Networks, explains why it is important for network operators to add IP-based distributed call managers, or transparent local proxies (TLPs), to their networks to ensure continuity of service.

Making the Carrier Grade

Carrier Ethernet is one of today’s hottest public networking trends. Network simplicity, high-bandwidth capacity, easy provisioning, low-cost electronics, and widespread interest from enterprise customers already familiar with Ethernet makes the technology extremely attractive. But making Ethernet carrier-grade is not an easy task given the diversity of access and transport networks, the need to ensure service reliability end to end and the demand for service level guarantees. In this reference guide, RAD Data Communications gives network providers information on the key issues involved in deploying carrier Ethernet.

The Telcos Guide to the Video Galaxy

Just about every telco, whether it’s serving a million subscribers or a thousand, is either already providing video services or has a plan to do so. In this guide, James Farmer, Wave7 Optics’ chief technology officer, writes “Everything You Need to Know about Video.” Farmer explains encoding and transport technology and compares transmission technologies such as broadcast and IPTV. He discusses who the telco’s primary competition is in delivering video, namely the cable and statellite providers, and he explains how a telco can make money providing video.

It's All in Your Headend

In order to deliver an Internet Protocol Television (IPTV) service, network providers must install an IPTV headend that works in conjunction with IPTV middleware and other systems such as conditional access and video servers. The headend must be capable of transmitting the greatest number of channels and best image quality, while conserving as much bandwidth as possible. In some cases where bandwidth is plentiful, the headend must support MPEG-2 video, but in cases where bandwidth is scarce, the headend must also support MPEG-4. Cisco Systems Scientific Atlanta division offers a flexible IPTV headend that any operator can use.

Sorting Through the IMS Hype

Although the IP Multimedia Subsystem (IMS) architecture has gone through a hype cycle that’s left some observers disillusioned with the promise of the technology, network operators are beginning to speed up their deployment plans for “pre-IMS” next generation networks, which incorporate elements of IMS architecture. That could signal that the worst of the hype is behind IMS and the architecture may finally be ready for prime time. In this perspective, Sonus Networks explains its view of IMS and what’s next for the architecture.

Benefits of IP GPON

Carriers must choose the right access platform for their gigabit passive optical networks (GPONs), or they risk losing a substantial amount of bandwidth and revenue potential. In this article, Tellabs explains the benefits of using Internet Protocol (IP) GPON and outlines the inefficiencies associated with Asynchronous Transfer Mode (ATM) GPON.

When RIO Networks, a telco providing voice, data and video services across Oregon and southwestern Washington, decided to build a next-generation broadband network, the company turned to ZyXEL for access equipment. ZyXEL supplied its line of Multi-Service Access Node (MSAN) products. RIO had very specific objectives in mind when selecting its access vendor: The telco wanted to be able to roll out differentiated services quickly, increase monthly revenue, increase network utilization and reduce costs. Find out how ZyXEL helped RIO achieve its goals.
