PTCL ONU Service – Point Of Criticism

PTCL ONU Service – Point Of Criticism?

PTCL launched triple-play service:

Pakistan telecommunication limited introduced a triple play service. Subscribers of that service can enjoy more than 100 TV channels, DSL and a regular phone service all just on one phone line. PTCL sources claimed that PTCL has invested 3.5 Billion PKR in this project and the triple-play service will charge PTCL customers around 1,500 Rupees per month.

One may be wondering that what is the difference between the earlier DSL provided by PTCL before the launch of triple play service and after the launch. Answer is simple that is company has overhauled its system and has replaced copper wires with optical fiber system completely to ensure best possible service. That’s why this service is also termed as ONU service; Optical Network Units service. Actually Optical network units have been installed in several exchanges to provide efficient and quality service via optical cables system. Company is investing without any offenses and hesitation just to provide best possible service to customers that there is. This point can be justified by the fact that one ONU costs rupees 10 million and more than 350 ONUs have been installed from exchanges to telephone cabinets.

Can we afford such technologies?

Before the launch of ONU connections there were old copper cables acting as a medium between telephone and exchange they didn’t need any source to boost their signals up. But fiber optics needs an electric source in order to connect to exchange, MEANS NO ELECTRICITY NO CONNECTION, then in a country like Pakistan where we are facing severe power cut issues how can we afford such latest system??

There are a few statements coming from PTCL sources about the backup batteries installed in the cabinets that can keep connection up till 6 to 7 hours in case of load shedding, but on the other hand the subscribers are wildly complaining about no such backups and frequent connectivity loss in case of power cut.

So is this ADVANCEMENT?

Today, when this super service has been launched we are still sitting on the issue tables and trying to justify that ONU connections are much better than the old copper ones’

Whatever we conclude, whatever we tell to media one thing is clear that in this deadly load shedding phase People can’t afford ONU system. I am not saying the service is bad or substandard but I am just pointing out the inefficiency of our institutes. They have spent so much money on the ONU service without creating its basics that is electricity.

Moreover, I think subscribers of ONU connections can still afford lack of DSL connectivity during load shedding but what about the call service which also drops along with the TV and internet during load shedding, as obviously that is also depending on optical fiber networks. So, No light No TV, No net and No CALLS even.

Isn’t it the point of criticism for anyone?? Yes it is!!!

Wireless at Fiber Speeds New millimeter-wave technology sends data at 10 gigabits per second. By Kate Greene There's no shortage of demand for faster wireless, but today's fastest technologies--Wi-Fi, 3G cellular networks, and even the upcoming WiMax--max out at tens or hundreds of megabits per second. So far, no commercial wireless system can beat the raw speed of optical fiber, which can carry tens of gigabits per second. One way to achieve faster speeds is to harness the millimeter-wavelength frequency of the wireless spectrum, although this usually requires expensive and very complex equipment. Now, engineers at Battelle, a research and development firm based in Columbus, OH, have come up with a simpler way to send data through the air with millimeter-wave technology. Earlier this year, in field tests of a prototype point-to-point system, the team was able to send a 10.6-gigabit-per-second signal between antennas 800 meters apart. And more recently, the researchers demonstrated a 20-gigabit-per-second signal in the lab

Five Reasons Why Microsoft’s BING Outshines Google

Five Reasons Why Microsoft’s BING Outshines Google

By Bryan Lambert

PullQuote 222On June 3, 2009 Microsoft officially unveiled its latest incarnation of the search engine: Bing! Yes, Bing, as in cherry, as in Crosby as in BING! I found it! Bing is not so much a search engine as it is a “decision engine”. Bing is what Google was 10 years ago, fresh, innovative, and (dare I say it) cool. But how does it stack up to the behemoth of the search engine world? Pretty well actually, and with this Tech Tip I’ll give you FIVE reasons why Bing outshines Google!

ONE - It’s all about the results baby!

Face it, why do more people today use Google than any other search engine out there? In a word, results – pertinent results to what you’re looking for. However, sometimes to get the results you want, you have to wade through a lot of chaff. It's analogous to dumping a waste can of papers onto the floor and searching for one tiny scrap. With Bing, you get “enhanced results” – what I mean by that is that you get intelligently organized results quickly and efficiently. With many of the search results, you can hover over the right-hand side and get a pop-up window with more information on that particular result. However, along with these results you also will find that you have a plethora of refinement tools to drill down to exactly what you’re looking for. These refinement tools brings us to reason Two.


TWO – The silver platter – that cool left-hand navigation pane

Under the heading of “how could something so simple and elegant be so powerful,” you can now add Bing’s left-hand navigation pane. This pane saves you so many steps in searches that in a short time you’ll wonder how you lived without it. With it, you get your search results categorized, possible related searches, a “reference” pulled from Wikipedia (if one exists), a quick link to images and videos as well your search history - all in one convenient package. Speaking of images and videos, let’s take a look at reasons Three and Four.


THREE and FOUR – Images and Videos done right

Every search engine can search images and videos, and they can mostly come up with what you want – but many times the presentation leaves a lot to be desired. With Bing you get image and video results on steroids. For instance, with the image results it is actually possible to just continually scroll down (instead of hitting next, next, next), and the next set of images are dynamically loaded (they call this the “infinite scroll” feature). Also, with the image results you get some really cool filters (in that nifty left-hand navigation pane) that filter not just by size, but by layout, color, type and “people” (very cool). Hover over an image, and you can also get an option to “show similar images.”

The videos are cool in that if you hover over the video, it starts playing a snippet of it right in the search result box (some have complained about this, but the content filter is set to “moderate safe” by default – turn it off and you see that same kind of “results” you’d see on any other video search engine (just without the auto-playing snippet part)). The videos too have easy to use filters in the left-hand navigation pane such as length, screen size, resolution and source just as the images have. Click on a video and a larger version of it pops to the top of the results page giving you the option to watch it right there, or go to the actual website. It is actually this and other little things that really make Bing shine. Speaking of little things, this brings us to reason Five.

FIVE – The little things

There are so many little cool things that come along with Bing that it is hard to know where to start. From “instant answers” where you can literally type in “traffic” and get your local traffic, to its Local Search (which runs circles around other local search features I’ve seen on other search engines), you'll be amazed at the usefulness of the Local Search features where you can not only find what you’re looking for, but can get one-click directions and a bird's eye view. It seems the folks at Microsoft sat down and decided to do the search engine right – or rather decided to bring the search engine, rather, decision engine into the 21st century. All this and I haven’t even touched on the travel or shopping features of Bing. For more information, I’d really recommend checking out Bing’s product guide at http://www.discoverbing.com/.

Final Words

Really, the more you play around with Bing, the more you’ll love it. Now, I know that some of you are thinking that Google fulfills all your search needs and that “Bing is just there to be there” so why bother checking it out. To this I say, “give it a try” (or as Microsoft would say, “Bing and decide”), and you too will find out why Microsoft’s Bing will outshine Google.

A History of the USB Standard

A History of the USB Standard

Universal Serial Bus (USB) is a serial bus standard for connecting peripherals to a host. It was designed to allow peripherals to be connected using a single standardized interface and to improve plug and play capabilities by allowing peripherals to be connected or disconnected without having to reboot the computer or turn the device off. This bus can connect devices including mice, keyboards, gaming controllers, scanners, digital cameras, printers, digital media players, flash drives and external hard drives. USB has become the standard connection method for the majority of consumer electronic devices. To date, billions of these devices have been introduced into the consumer electronics market.

The USB Implementers Forum, Inc. (USB-IF) is a non-profit corporation founded by leading companies in the computer and electronics sectors. The organization was formed to provide a support group and forum for the advancement and adoption of USB technology. The Board of Directors is currently comprised of the following companies: Hewlett-Packard Company, Intel Corporation, LSI Corporation, Microsoft Corporation, NEC Corporation and ST-Ericsson.

USB 1.0 and 1.1
The USB 1.0 specification was introduced in 1994 with two data rates, Low-Speed (1.5 Mbps) and Full-Speed (12 Mbps). It was designed to replace the myriad of connectors at the back of PCs and simplify software configuration of communication devices. The 1.1 specification was released in 1998 and was the earliest revision to be widely adopted.

USB 2.0
The USB 2.0 specification was released in 2000 and was standardized by the USB-IF in 2001. Several companies led the initiative to develop a higher data transfer rate of 480 Mbps, about 40 times faster than the 1.1 specification. Also known as Hi-Speed USB, 2.0 expanded the range of external devices that could be used on a computer. And, offered backward compatibility with previous generations.

USB On-The-Go
Many USB devices are portable, and there is an increasing need for devices to communicate directly with each other without a computer. The On-The-Go Supplement makes it possible for peripherals to communicate directly with each other. On-The-Go features include:

- Limited host capability to communicate with selected USB peripherals
- A small connector appropriate for the mobile form
- Low power requirements for preserving battery life
- Ability to be either host or peripheral and to dynamically switch between the two.

Locking Folders

Locking Folders
By Mansoor Ahmad

There are plenty of software which locks drives and folder to protect your confidential data. Why waste money on such tools when you can do it with a simple registry tweak? Here’s how: Caution: Before you attempt these tweaks, please make sure that you have a backup of your registry, just incase something goes wrong in the middle. Locking Folders: Consider you want to lock a folder named XXXX in your E:\, whose path is E:\XXXX. Now open the Notepad and type the following ren xxxx xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D} Where xxxx is your folder name. Save the text file as loc.bat in the same drive. Open another new notepad text file and type the following ren xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D} xxxx Save the text file as key.bat in the same drive. Steps to lock the folder: To lock the xxxx folder, simply click the loc.bat and it will transform into control panel icon which is inaccessible. To unlock the folder click the key.bat file. Thus the folder will be unlocked and the contents are accessible.
