Ordering An SDSL Line

Wednesday, November 19th, 2008
Derek Rogers asked:


SDSL (Symmetric Digital Subscriber Line) Broadband provides high speed internet access over ordinary copper telephone wires. It is primarily used by small to medium businesses. With SDLS there are low contention rates and identical uploading and downloading speeds. This type of broadband is the ideal mid-point between ADSL (Asymmetrical Digital Subscriber Line) and a Leased Line. The service is also especially useful if you have home-workers needing faster upload speeds.

If this is a new installation, you will probably want to purchase an integrated DSL (Digital Subscriber Line) modem and router. If you already have an existing router in place, then a stand alone DSL modem will do. If you do not currently have networked computers, then you will need to run something that is known as a CAT5 cable (a Cable and Telephone cable) from the location of your modem or router to each of the computers. You may also consider installing a wireless router if cabling is a problem, but generally a wireless router is not very secure and is limited to about 50 feet. Some providers may have limitations on Customer Provided Equipment (CPE) being connected to their network, and it may require you to install specific types of equipment to allow for the provider to properly manage and maintain their network.

The most obvious choice for ordering SDSL Broadband is always the local incumbent phone company, because these companies own the copper wire that already runs into the user’s location they have an advantage over any other service provider. You can also have DSL provisioned through a third party provider.

There are a number of other companies that market and resell SDSL Broadband services. The third party DSL providers rent the copper circuit from the local incumbent phone company and then will provide the path to the internet along with ISP (Internet service provider) services, such as Email, web space, DNS and newsgroups. Traditional ISPs may also sell SDSL, however they tend to offer the service only in the local market they serve or are marketing access bundled with their ISP services.

Although costs vary widely, there are a few standard expenses. If the user had no previous DSL installation, there is usually a onetime cost for the installation, setup and the hardware. The hardware includes a router or modem both are provided by the SDSL Broadband provider. The monthly recurring charge will vary based on who is providing the service and whether any special offers are in place. To give you an idea, usually prices will start from a monthly cost of £209.99 (around $420 US Dollars) for a 512kb connection and up to £249.99 ($450 US Dollars) for a 2 Mb connection.

Exact ordering details about this broadband connection details depend on the SDSL Broadband connection provider, be it the Phone Company, a third party or an ISP. Also the location of the provider and the user play key roles in the connectivity, installation and price. For most small business the ordering and installation process is easy, quick, and worthwhile in the end.

What is Cat 6?

Saturday, November 15th, 2008
Robert asked:


ort for Category 6) refers to an Ethernet cable as defined by Electronic Industries Association and Telecommunication Industry Association (EIA/TIA). Like its name suggests, CAT 6 is a sixth generation of twisted pair Ethernet cabling. The cable itself contains four pairs of copper wire and utilizes all of them, unlike the earlier version, the CAT 5. CAT 6 supports Gigabit Ethernet and supports communications much faster (about twice) than the CAT 5e, the other standard for Gigabit Ethernet cabling. It also features more stringent specifications for crosstalk and system noise. This cable may be identified by the printing on the side of the cable sheath. CAT 6 supports 10BASE-T/100BASE-TX as well as 1000BASE-T (these are IEEE standards that define the requirement for sending information at various speeds as well as various aspects of running baseband Ethernet on the cabling) and may in the future support 10GBASE-T (10 Gigabit Ethernet) though there will be limitations as regards the length if the unshielded CAT 6 cable is used. As is usual with all other types of twisted pair EIA/TIA cabling, CAT6 cables are limited to a maximum run rate of 100m (328 feet).

The CAT 6 cable is being made with 23 gauge conductor wire as opposed to the slightly smaller 24 gauge that is used to make CAT 5. However, using 23 gauge conductor is not really a requirement, and its possible to make a CAT 6 cable with 22 or 23 AWG gauge wire for ANSI/TIA-568-B.2-1 specifications, provided the cable can meet the required specifics standards. CAT 6 cable is normally terminated in 8P8C modular connectors when used as a patch cable. CAT 6 connectors are made to lofty specifications that aid in reducing noise caused by crosstalk as well as system noise. Significantly, attenuation, Near End Crosstalk (NEXT) and Power Sum Next (PSNEXT) are lower when compared with CAT 5 or CAT5e.

Some varieties of CAT 6 cables may be too big and it becomes tricky to attach to 8P8C connectors without using a special modular piece. Such cables ate technically not standard. Should one mix the components of various cable standards, this will result into sub-optimal performance of the signal path which will be reduced to the lowest category. The cable is terminated in T568A or T568B schemes, and it matters a little as to which scheme is used since both schemes (though T568B is more widely used) are both straight through (meaning pin 1 will go to 1, pin 2 to 2 and so on). Any mix-up of the terminating patch codes between the two schemes does not produce pinout problems in a facility. It may, however, slightly degrade the quality of the signal even though the effect of this is marginal.

Twisted pair cable like the CAT 6 come in two main varieties-stranded and solid. The solid one supports the longer runs and performs best in fixed wiring configurations like those that are found in office buildings. The stranded AT 6 cable, on the other hand, is pliable and is better suited for shorter distances. CAT 6 cable comes with a higher price tag than CAT 5/5e though the price is justified with better performance.

Accessories for Your Laptop Computer

Accessories for your new laptop computer

Just spent big money on another laptop?.Now you need accessories.Here are a few accessory ideas you may want to consider to make the set up complete.

1: Notebook bag

You can’t very well go travelling around the world with your laptop exposed to the elements.

When it comes to laptop bags, you can spend £15 for a basic case made from less expensive materials or up to a hundred pounds on one made of quality leather.some laptops have the bag as a give-away, i find that you can get an affordable one by shopping around and not neccessarilly buying the exact one, but one that will do the job. Personally i pick one that is large enough to hold a few accessories besides.

2: Software

Did your laptop come with software? If so, did it come with the right software - the software you actually need to perform whatever tasks you require?

Don’t guess you have everything you need. You’ll probably need to add some software, as well as go on the net to update the software that was included.

3: A Real USB Mouse

The inbuilt touch-pad does the job. However, given the choice, most people would rather use a real mouse.

If you stop and think for a moment, you’re likely to realize that many places where you’ll be computing actually are suitable for a real mouse.

So one of the most useful laptop accessories you can buy is a USB mouse, keep it in your bag, and use it whenever you’re able.

4: A Cat5 Ethernet Cable

Your built-in Ethernet port won’t do you much good if you get to your hotel room, discover an Ethernet connection, and don’t have a cable. Some hotels provide them; others don’t. Always come prepared with the right cable.

5: A Standard Telephone Cable

The same holds true for your modem connection. If you don’t have a cable to get you from your computer to the phone jack, you’re not going to link to the net.

6: Disposable Cleansing Cloths

Over time, the display on your laptop is going to get dusty, or even grimey. You’re diceing with the death of your laptop if you attempt to clean your display with paper towels and spray cleaners.

Instead, use disposable cleansing cloths. These essential laptop accessories are designed specifically to clean laptop displays and they are cheap to boot, about £2 a pack . Always have a pack on hand.

7: USB Drive

A USB drive is a storage device about the size of your thumb that plugs directly into a USB port.

Capacity-wise, they’re relatively small - usually well under 100 MB. However, they’re very useful for moving files quickly and easily from one computer to another, e.g., moving a PowerPoint presentation from your laptop to your business associate’s laptop.

A USB drive also makes a great temporary backup medium for the really important files you create on the road.

8: Blank CD-R Discs

You’ve just finished your big sales presentation. Someone from the audience approaches you afterward and asks for a copy of the presentation.

You’ll make a better impression if you burn them a CD of the presentation on the spot.

9: Stereo Headset

It’s great to be able to watch DVD movies no matter where you are. Imagine watching your favourite movie at 30,000 feet.

There’s just one problem.

The family in the row behind you has absolutely no interest in hearing the dialog from the latest horror movie

Do yourself and everyone around you a favour. When you’re watching movies or listening to music in public, use your headphones.

10: Security Device

Laptop security devices come in many shapes and sizes.

For example, most laptops include a security dock that allows you to attach your laptop to some immovable object via cable, much like you’d lock up your bike on the street.

A List of Great House Design Tips

Tuesday, November 11th, 2008
Bruce Lipski asked:


If you are thinking of designing your own house, here are some tips you might want to consider:

1)Shower stalls should be made wider than in years past. This is because more people are heavier than they used to be.

2)Radiant heat is healthier than the normal forced air heat that is in all new homes today. Radiant heat will increase the value of your home and it is best installed when the house is built.

3)Make sure you put the laundry room on the same floor as all the bedrooms. Many houses have the laundry room on the main floor and the bedrooms upstairs. Who wants to have to carry all the laundry up and down the stairs everytime?

4)If you must have the laundry room downstairs and the bedrooms up top, you might consider installing a laundry chute.

5)This is your chance to have all the built in speakers installed exactly where you want them. You might also think about soundproofing some rooms or the whole house.

6)Do you like wine and want a wine cellar? This is your chance to have one built just like you want it.

7)A large entry way is always nice and sets the whole tone for your new house. Make sure you make your entry way large enough to have a nice coat closet and room to greet visitors.

8)Designing your own house gives you the chance to put in higher ceilings. Rooms look and feel larger with higher ceilings and this should always be done if possible.

9)Many new homes now have garages that are not wide enough for SUV’s. By designing your own house, you can make sure this does not happen. Also make sure your driveway is wide enough to accommodate any vehicles you might have.

10)If you plan in advance where you will want all your furniture and electrical gadgets to go, you will then be able to insure the right quantity and placement of all electrical outlets. Many times when you move into a new house, you will find the light switches and outlets are not in the places you would like them

11)Make sure you install new CAT5 wiring throughout your house for your computers. All new homes should come with the latest technology or you may have to lower your price when you go to sell the house.

12)Put two sinks in the kitchen instead of one. This is one of the advantages of doing your own house design - you can add a sink like this that would never come in a regular home built by a company builder.

What do i need to run a cat5 cable from one floor to another?

Wednesday, November 5th, 2008
coryw68122 asked:


I need to run a cat5 cable from my top floor to my basement, as the router is too slow down there for my Xbox. I would like to add a wall outlet where I plug in a cat5 cable from my router, then inside the wall have a longer cable that leads to another wall socket in the basement for me exting cat5 cable.

Where can I buy these wall sockets and how do I get it through the wall?

Thanks!

Cat5e for High Speed Networks

Tuesday, November 4th, 2008
Mike Nicholson asked:


Bandwidth precedes data rates just as highways come before traffic. Doubling the bandwidth is like adding twice the number of lanes on a highway. The trends of the past and the predictions for the future indicate that data rates have been doubling every 18 months. As streaming media applications such as video and multi-media become commonplace, the demands for faster data rates will increase and spawn new applications that will benefit from the higher bandwidth offered by category 5e.

Cat5 enhanced (Cat5e), supports short-run Gigabit Ethernet (1000 Mbps) networking by utilizing all four wire pairs and is backward-compatible with ordinary CAT5. Currently defined in TIA/EIA-568-B, Cat 5e provides performance of up to 100 MHz, and is frequently used for both 100 Mbit/s and gigabit Ethernet networks. Cat5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. Although 1000BASE-T was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T.

The Gigaplus range of Cat5e products offer customers a Gigabit Ethernet solution. The Gigaplus system offers a guaranteed performance that not only meets the requirement of the relevant standard, but offers the comfort of substantial headroom. In the current market GigaPlus represents a sound investment for general office horizontal cabling and residential cabling for networks running Gigabit Ethernet applications.

Some of the Cat5e systems like Belden IBDN System 1200 have been developed to support high-speed network applications such as Gigabit Ethernet and provide clear bandwidth up to 160 MHz; an increase of 60% over Cat5e standard of 100 MHz.

These cables incorporate a patented design which provides complete quality control during the manufacturing process. This provides high quality cables that consistently offer improved channel performance and large cabling systems for all new cabling installations.
