What’s the Difference Between DS3 and T3 Bandwidth?

Posted by admin Comments Off

Don’t be confused about the difference between DS3 and T3 circuits. These terms are really synonymous. Instead you should focus on what they can do for you…and the best scenarios for application.

Digital Signal (DS) is a system of classifying digital circuits according to the rate and format of the signal (DS) and the equipment providing the signals (T). DS and T designations have come to be used synonymously so that DS1 implies T1, and DS3 implies T3.

A DS3 line (also known as a T-3) is an ultra high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is equal to approximately 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network. A DS3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic. Other example applications include large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, research labs, video conference centers and software development companies. A DS3 is the second fastest, non optical connection offered in North America. A DS3 line is comprised of 28 T1 lines, each operating at total signaling rate of 1.544 Mbps.

DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mb/s of dedicated Internet connectivity. This is an ideal solution for users who have outgrown their T1 connections and are in search of unlimited, high-capacity access. A DS3 line actually consists of 672 individual channels, each of which supports 64 Kb/s. DS3 lines are extremely high bandwidth connections into a carrier’s backbone. They typically include SLAs (Service Level Agreements) that guarantee uptime and performance.

The DS3 signal itself is composed of 28 DS1 signals and is constructed using a two-step multiplexing process. First, the 28 DS1 signals are multiplexed into seven DS2 signals. Second, the seven DS2 signals are multiplexed into one DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communications, and bit stuffing control information.

Line rate: 44,736,000 b/s

Signals: 7 DS2 signals = 28 DS1 signals

Overhead bits:

56 bits total/frame

F-bits (framing) 28 bits/

M-bits (multiframing) 3 bits/

C-bits (stuffing) 21 bits

X-bits (message) 2 bits/

P-bits (parity) 2 bits/

Data bits between overhead bits 84

A DS3 connection is comprised up of two monthly charges: the local loop and the port charge. The local loop charge is the cost of the circuit provided by the Local Exchange Carrier (LEC) that allows DS3 access into the carrier’s network. The loop charge is based on the distance from the customer’s location to the edge of the carrier’s network; the farther the customer is from the network, the more the loop will cost. Nearly every carrier prices loops differently so it is in your best interest to price DS3 service with several providers to ensure that you get the best deal.

DS Internet Access is the ideal solution for businesses that require high-bandwidth access at a reduced price. Whether you host high-traffic Web sites, support Web hosting or need high-capacity bandwidth on an as-needed basis, there’s a level of DS3 service (Full or fractional) that will meet your needs. Fractional to full DS3 or T3 circuits run from speeds of 3 Mbps up to 45 Mbps.

For customers that require more bandwidth than a T1 line can provide but do not yet require the capacity of a full DS3 line, a fractional DS3 connection is the ideal solution. A fractional DS3 is similar to a full DS(T)3, only with some of the channels turned off. This reduces the total monthly cost and provides additional capacity that can be turned up in a matter of days. Unfortunately, the DS3 (T) loop is still required for this service.

If a full DS3 line is more bandwidth that you really need, it is also possible to get Fractional DS3, which gives you a portion of full DS3 bandwidth at a lower cost. Of course, DS3 is also available in multiples to increase bandwidth, similar to bonded T1 service.

DS3 service can be deployed for a wide verity of applications. The most common uses are DS3 point-to-point, DS3 internet, DS3 frame relay, DS3 voice and DS3 VPN. The pricing for these connections varies widely depending on the carrier, location of service and the application for which the connection is being used.

Top 10 Meeting Ice Breakers

Posted by admin Comments Off

Getting people comfortable in a group setting before a team meeting can be the best investment of ten to 15 minutes of time that you can make. Ice breakers get creative juices flowing, can increase the exchange of ideas, establish team identity, and create a sense of community. All of these items are important in forging top productive teams. But how do you get people to participate and not feel uncomfortable with an ice breaker?

For meetings in a business setting in which participants are professionals, ice breakers that require actions not normally associated with day-to-day behaviors in the office generally make people uncomfortable. Successful ice breakers for these type of groups generally consist of having attendees share memorable information with each other, create innovative ways to get people to introduce themselves to each other, or have group members collectively work on a problem where everyone has to contribute.

We’ve selected our top ten team meeting ice breakers that are sure to get your meeting participants relaxed and ready to focus on your agenda as well as to connect with others in the group.

1. Brainstorm!:Break the meeting into teams of four or five. Give each team a topic. Pick topics that are fun and simple like, “What would you take on a trip to the desert?” or “List things that are purple”. Give your teams two minutes, no more, and tell them “This is a contest and the team with the most items on their list wins.” Encourage the teams to write down as many things as they can and not to discuss anything, just list things as quickly as possible. At the end of two minutes, the team with the most items on their list wins! This helps people to share ideas without fearing what other people will think.

2. Same or Different:

Divide the meeting into teams of three or four and give each team a large sheet of paper and then give each person a different colored marker. Have each person draw a large oval such that each oval overlaps with the other ovals in the center of the piece of paper. Give the group or groups, a theme that pertains to your meeting objectives. Ask the participants to write down at least five or more entries in the non-overlapping and mutually overlapping areas of their ovals. Give them five minutes, no more than that, to talk about their similarities and differences and write them in their own ovals on the paper. If there is more than one group, compare results and identify common themes in both parts of the diagrams and what light these similarities and differences shed on the purpose of the meeting. This helps team members develop an understanding of shared objectives and in a non-confrontational way learn how their views differ from others in the group.

3. Fact or Fiction:

Have everyone write down three surprising things about themselves, two of which are true, and one of which is made up. Each person, in turn, reads their list and then the rest of the group votes on which “fact” they feel is the “false” one. If the group does not correctly pick a person’s made up “fact”, then that person wins. A group can have more than one winner. At the end, the whole group votes on which of the “winners” of the final round, had the most deceiving “fact”. This helps people get to know and remember their colleagues.

4. Free Association:

The object of this ice breaker is to have small groups generate as many words or phrases as they can that are related to a particular topic that focuses on the objective of your meeting. Give the group or groups a key word you want them to associate with and then give them two minutes to list, as quickly as possible, as many words or thoughts that pop into their heads. For example, if your company is trying to decide on whether to reduce travel and increase the use of teleconferencing, you might use the word “teleconferencing” and have people list as many words or phrases they can that they associate with the key word. For example they might say: “saves money”, “saves time”, “impersonal”, “need to see other people”, “get distracted”, “sound quality”…. This reveals what people are thinking, similarities in viewpoints, and possibly even problem areas or topics that need addressing or further discussion.

5. Nametags:

Prepare nametags for each person and put them in a box. As people walk into the room, each person picks a nametag (not their own). When everyone is present, participants are told to find the person whose nametag they drew and introduce and say a few interesting things about themselves. When everyone has their own nametag, each person in the group will introduce the person whose nametag they were initially given and mention something of interest about that person. This helps participants get to know and remember each other.

6. Desert Island:

Group people in teams of five or six and tell them they will be marooned on a desert island. Give them 30 seconds to list all the things they think they should take and each person has to contribute at least three items. At the end of 30 seconds, tell the teams they can only take three things. Have the person who suggested each item on the list tell why they suggested it and defend why their item should be one of the chosen three. This helps the team learn about how each of them thinks, get to know each other’s values, and how they solve problems.

7. Commonality Plus:

Group your meeting participants at tables. At each table ask the group to list ten ways that everyone in that group is similar. Let them know that they cannot list body parts or clothing and that what they select cannot have anything to do with work. One person at the table should be tasked to make their list. At the end of your time limit have the group share their list with all meeting members. This is a great opportunity for your meeting attendees to learn about each other’s hobbies, families, and common interests.

8. Line Up:

As people enter your meeting hand each one a piece of paper with a different number written on it. Ask the group to arrange themselves in numeric order without using their voices, hands, or showing their number. This helps the team to think of other ways to communicate with each other and to work together to achieve a common goal.

9. Meet and Greet Shoe Pile:

This works great in large groups and is a variation of the name tag ice breaker. Have everyone take off one of their shoes and throw it into a pile. Have each group member pick up a shoe and walk around the meeting room greeting other people as they try to match their selected shoe to the one another team member is wearing. This is a great way for new people to meet several members in a group.

10. First or Worst:

Have each member tell the group their first or worst job in turn. This easy to use ice breaker works great with teleconferences too and allows team members to spark conversation with each other and to have some fun commenting on the jobs that they have each done. Many of our top ten ice breakers can be used for on-site meetings and teleconferences alike. The nature of ice breakers is to get the group to talk, to share, and to get to know each other in a casual exchange. The best and most successful teams start with a little bit of fun; learning how to value what each member brings into the group. Ice breakers can help facilitate this exchange of information and comfort in doing so at the very start of the team forging process.

Ten Speech Tips for Writing Powerful and Persuasive Presentation

Posted by admin Comments Off

Have you ever had to give a speech?

Do you remember that feeling? A knot in the stomach, sweaty palms and a panic attack!

Not a very pleasant experience. And yet, I’m sure your speech was a success because 90 per cent of a typical audience want the speaker to succeed.

Yet according to The Book of Lists, speaking in public is one of our greatest fears.

Much of this anxiety is due to a lack of confidence in writing and preparing a speech rather than in the delivery.

Giving a presentation can be a great way to build your business, influence public opinion or kick-start your career.

It is an excellent way to stand out from the crowd and make a real difference in people’s lives.

What are the secrets of writing a powerful and persuasive speech for any occasion?

Here are 10 tips for turning a good speech into a great one!

1. Have a plan and set some objectives & outcomes.

There is nothing worse than not knowing what you want to achieve. Do you want to educate the audience, inform, inspire, motivate or touch their emotions? Always work out what you want to achieve before beginning the speech process.

2. Have a formal structure – beginning, middle and end.

Audiences love structure and the best speeches stick to this tried and true rule. As they say: “tell them what you’re going to say, tell them and then tell them again”.

3. Avoid having too much content.

Hands up those that are guilty of this sin. I know I am. I have lost count the number of technical presentations given by CEO’s, managers, scientists, engineers, geologists and other professionals who have just put too much content into their presentations. Far too much for an audience to absorb – remember even the best audiences face information overload after 20 minutes.

How do you overcome the content crisis? See Tip # 8.

4. Define who your audience is and use the most appropriate communication

channels to reach them.

Analyse how your audience likes to take in information – do they like to be visually stimulated or do they enjoy just sitting back and listening. Or do they like to get involved, to touch and feel in a kinaesthetic way. Work out the best mix of visual, audio and kinaesthetic and use this in your speechwriting.

5. Research your speech using a range of sources.

Be a keen observer of the trends your audience is likely to be interested in and keep a file of interesting articles and information. If you are time poor- a few quick questions when meeting an audience just prior to a speech, such as “what are the issues facing your business/industry/association at the moment?” can really help target your presentation and build rapport.

6. Use personal stories, examples and metaphors to make intangible concepts

tangible.

In many cases you are trying to sell ideas and concepts in a speech. These are intangible and often difficult for the audience to grasp. Personal stories, examples and metaphors make the invisible visible.

7. Have a strong opening and closing.

People remember the opening – first impressions count! The closing is important as it should reinforce the key message you want the audience to go away with in their head after they have heard the presentation. Ending with a ‘call to action’ can be a powerful way to get your audience to act on your message.

8. Add value and extra detail through a handout.

Here’s a tip: if you want to provide detail – put it in a handout! You can get far more content across in the written form than in a speech. Always refer to this in your presentation but hand it out after your speech so the audience is not distracted reading through it while you talk. There is nothing more soul destroying for a presenter to see the audience leafing through written notes rather than looking at you!

9. Use short words and plain English.

The short words are always the best words. Avoid jargon. Use active words instead of passive. This has far more impact in the minds of your listeners.

10. Evaluate and review on a regular basis.

There’s nothing more powerful than to hear back a speech you’ve written. If you are writing a speech for someone else always try and hear the speech or at least get some feedback. Recording and listening back to a presentation is the fastest way to improve your skills.

The Advantages and Disadvantages of Video Conferencing

Posted by admin Comments Off

Video conferencing is similar to the popular video phones where you can call anyone around the world and not only speak with them, but see them on your computer or television screen during the conversation. The difference is that video conferencing is intended to work for larger conferences rather than serving the needs of individual consumers, often using closed circuit television.

While many businesses have taken this technology under wing as a useful tool, there are advantages and disadvantages of video conferencing which must be considered before you decide if it will work for your meeting needs or not.

Advantages

1. Reach anyone you need to reach immediately, no matter what time of day it may be for anyone involved. Time differences between states and countries can be overlooked without anyone traveling long distances for the conference.

2. While a phone call may suffice for two people who need to have a short conversation, web-based conferencing allows large rooms of people at different locations to interact with one another effectively. Ten business execs in Amsterdam can easily interact with five others in New York and two in Tokyo to create a full conference with everyone able to see and hear perfectly.

3. PowerPoint and other visual displays can be shared with everyone attending the conference at the same time, giving the feel of everyone being in one room and keeping everyone on task and focused.

4. Virtual whiteboards allow people from different locations to add in their own thoughts or ideas into one collaborative space. This enables everyone to form a plan of action or collaborate on a design or slogan instantly.

5. It is possible, with some services, for everyone to gain access to another computer, seeing whatever is on that computer screen. With more advanced services, a document can even be changed and typed into directly from other computers connected into the conference. Businesses that require active collaboration on one project form can be greatly enhanced with this possibility.

Disadvantages

1. The price may be the biggest drawback for some people, though there are very cheap options if you do not require the more advanced features. Usually, a business that can make good use of the more advanced features often finds that the money they save flying clients or employees around the country or world more than makes up for the cost of the service provider. As fuel becomes more of an issue around the world, the price becomes less of a disadvantage and more of an advantage.

2. There are some human ways of communicating that do not translate very well over a distance, such as eye contact. When you sit in the same room with someone and listen to a speech or presentation you will make eye contact and they will judge who is paying attention by looking around the room. Much of this contact is not easily delivered through a webcam.

The advantages and disadvantages of video conferencing have to be weighed against your purpose and whether there will be something valuable lost through this technology that you don’t want to give up.

From computers to phones, here’s what’s coming.” “Fantasy of the 1980’s, now a reality.” “This isn’t a Hoverboard, but it’s almost as good.” “Self confessed Technology Geek, Jonathan Wrigley, paid double the $500 iPad price tag, for a friend to bring one back from the American Launch. Now he’s one of the first to own one in Australia.” “If I had a whole box of them, I could sell them… It would be gone within a day I would imagine.” “A cross between a laptop and mobile phone, 300000 were sold in the United States in just one day. Due to be released in Australia later this month.” “The fact that you are dealing with all of the stuff in a very hands on way, really does make it a lot more engaging. To launch something, you just tap on it. What it’s capable of now is by no means indicative of what it will be capable of, 6 months from now.” “But it’s not only the Americans that are coming up with such ground breaking technology.” “So Linda, this is the future of business meetings” “It’s called Real Presence Conferencing.” “So I’m going to call Sydney now.There they are.
