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.

Satellite Internet – It’s Back

June 3, 2005

I remember in the mid nineties – was it 1995? -- I was at an Internet World show in LA and I met with people from DirecPC, a division of DirecTV who extolled the virtues of browsing by satellite. I was intrigued but never tried the service. According to the WSJ a new effort is underway from a number of companies to provide us once again with satellite Internet service.

Veraz Maps IMS to its Softswitch

June 2, 2005

Veraz Networks new ControlSwitch modules map easily to the leading NGN groups. Groups such as ETSI TISPAN, MSF, ITU, ATIS are evaluating adoption of the core IMS within their reference architectures to provide mobility and simplify service delivery to any access network.

The ControlSwitch enables carriers to achieve a graceful migration path that exploits full network and subscriber service convergence across wireless and wireline networks. The advanced ControlSwitch architecture provides a path for service providers interested in enhanced business models, such as Mobile Virtual Network Operator (MVNO). These networks will then leverage the power of the core IMS-ready softswitch to deliver voice and/or multimedia services to subscribers across any available access network, including over broadband access media such as DSL, cable, metro Ethernet or wireless broadband, in addition to mobile networks and existing narrowband digital loop systems.

“Carriers will deploy IMS in stages; initially wireline operators will use the technology in order to upgrade their switching architecture to facilitate value added voice services to curb decreasing voice revenues.



Botaxes

June 1, 2005

A while back I received an e-mail or comment on my blog, I really cant remember where I saw it. The gist of fit was that the government will just basically tax everything it can. VoIP, luxury cars, whatever it can find. That is how they generate revenue and saving and slashing costs is not a popular concept in the government.

I was reminded about this comment today when I was reading a WSJ article titled The Nose-Job Tax where NJ has already instituted a cosmetic surgery tax last summer.

Covad Investment

June 1, 2005

I received this request about Covad today. This was in response to recent article. I feel like the Jim Cramer of VoIP Here is the question and answer:

Question:

Mr. Tehrani,

I just finished reading you article, “Best VoIP Investments of 2005“ (published in February 2005) and noticed you didn’t make mention of COVAD Communications. The article seemed to focus more on smaller companies that were marketing specific, niche-type capabilities, as well as peer-to-peer technology, and perhaps that’s why COVAD was not mentioned.





WiFi in Church

June 1, 2005

BT may have WiFi enabled the first church – well at least the first one I have heard of. The church is in Wales and the Reverend Keith Kimber at St John’s Rectory Church in Cardiff said, “The church has to move with the times and I wanted to make St John's a sanctuary for everyone, including business people with laptops and mobiles." He continued, "I have no problem with people quietly sending an email or surfing the Internet in church, as long as they respect the church." I am pretty impressed by this whole concept of Internet access in houses of worship. What is next? Perhaps bibles and Korans will be read electronically?

Digicel Points

June 1, 2005

I was in Aruba last year and noticed Digicel was the leading (only?) provider on the island. Digicel puts out a steady stream of releases and seems pretty forward thinking. As a monopoly provider you would think hey would sit back and count money. This doesn’t seem to be the case.
