VDSL and Vectoring are Important Parts of Broadband Deployment

By: Wendy Zajack, Dir. Product Communications, Alcatel-Lucent

From original on Alcatel-Lucent corporate blog

A few months ago our home WiFi slowed to a crawl. At first we thought it was a temporary thing, but after my son ran a diagnostic there was a problem with our high-speed broadband.  

While the technician was fixing it, he mentioned that for an extra $10 a month we could get a faster plan.  Living in the US we already (in my opinion) pay enough for our monthly broadband package so I immediately said ‘no.’ But I told my kids that IF they wanted to pay for it … we would consider it.

LTE Interworking: Is it really necessary?

May 28, 2013

Last week, Dialogic hosted “Interacting with LTE Networks,” a webinar that covered signaling and media interactions trends for 2G, 3G and LTE networks.  There Are many signaling interworking scenarios to consider. For example, there is a spec called TS 29.305 that covers interworking between Diameter and SS7/MAP.  This would occur when LTE and 3G/2G network interactions need to occur.

LTE Network Interactions

May 14, 2013

According to a recently released GSMA Wireless Intelligence infographic, there are 163 live LTE networks today, and that figure is expected to grow to more than 400 live LTE networks by the end of 2017.  However, there are still hundreds of 2G and 3G networks that these LTE networks will need to connect to, not to mention the million or so (depending on source) WiFi networks. 

The signaling interworking between  Diameter, SS7 and Radius is an important issue that needs to be solved. 

The Evolution of International Telecoms Week (ITW)

May 7, 2013

ITW, as described on its website is “the annual meeting point for the wholesale telecommunications community and offers various networking opportunities through meeting rooms, an integrated exhibit and bilateral table area, numerous breakfasts, lunches and cocktail receptions and provides a wide range of conference sessions for attendees to benefit from.”

This market is evolving. ITW was historically about DM interconnect minutes. But now, VoIP minutes and wireless minutes are becoming increasingly important.

"How Does Dialogic Fit In with WebRTC?"

May 1, 2013

This blog represents the last of the series of questions we received from attendees of our February 20th WebRTC webinar.  Quite a few of the questions we received during the webinar asked about Dialogic products that could be used to build WebRTC solutions, along with general questions on making the technology work for various use cases.  One solution our customers have found valuable is the  PowerMedia XMS, which is a software media server and IP multimedia system (IMS) media resource function (MRF).  Since WebRTC is poised to dramatically lower the barriers to rich multimedia communication sessions across so many use cases, we believe that WebRTC adoption will drive demand for the scalable, mixed media environment for audio and video.

Why would you want a software based session border controller?

April 30, 2013

Why would you ever want a software-based session border controller (SBC)?  Is it even feasible? Right now, SBC’s are boxes that often implemented at the edges of IP-based networks.  It might seem unlikely for a hardware node of that critical network element morph to become a piece of software.

"The contact center use case looks like a natural for WebRTC, but how will that work?"

April 24, 2013

“The contact center use case looks like a natural for WebRTC, but how will that work?”

From our company’s viewpoint, implementing many of the WebRTC use cases in the modern contact center is a matter of normalizing the media and signaling streams between systems to interface with the existing service. The telco perspective in this context doesn’t mean exclusively carriers or service providers, but a wider view of enabling WebRTC endpoints to access known communication services or solutions, such as a contact center.

While our on-demand webinar described a click-to-call WebRTC use case that may already be emerging in the market, another use case has cropped up that is a practical application in the area of agent login and soft-clients.  

Impact of the New Video Codec H.265

April 23, 2013

In January, a new video codec called H.265 (also known as High Efficiency Video Coding (HEVC) was approved by the ITU-T.  This is significant for a couple of reasons:

It needs only half the bit rate of the best codec out there today (H.264) to provide the same or similar quality video.  You can even see it in this YouTube video.

"Where do IMS and WebRTC Intersect?"

April 17, 2013

The IP Multimedia Subsystem (IMS) is an architectural framework for delivering IP multimedia services. It is based primarily on SIP as a rich, real-time media session protocol for IP networks, and as such, relies on SIP-based endpoints and soft-clients to register and support subscribers on the services (at least those services that are truly multimedia in nature with HD voice and video interactivity, and not ‘skinnied’ down through gateways to a narrowband voice service).

The care and feeding of SIP client applications that enable the IMS service subscribers represents a considerable effort and cost to carriers for their on-net IMS service subscribers. Extending the IMS service reach with soft-clients to off-net endpoints, meaning those that are on other carriers broadband and mobile networks, presents another set of challenges, including various app store navigations and negotiations.

WebRTC Webinar Q&A #2 "Why WebRTC when we have Skype?"

April 17, 2013


“Why  WebRTC when we have Skype”?”

This is a really good question.   After all, Skype is the dominant real-time communications technology on the web with hundreds of millions of users and isn’t very hard to use.
