Creating Flexible Next-generation Networks with SIP Signaling

Monday 16 February 2009

Creating Flexible Next-generation Networks with SIP SignalingNext-generation network (NGN) deployments are on the rise. Mobile and fixed line operators are moving to Internet protocol (IP) technology to reduce their transport costs, deliver voice-over-IP (VoIP) services to consumers and enterprise customers, and improve the delivery and management of new multimedia services.

As IP and session initiation protocol (SIP)-based services proliferate, so do the requirements placed on the network to support them. Operators are discovering a downside to their softswitch-based NGNs; they lack the scalability and flexibility to support multimedia services, access independence or network growth.

The Missing LayerIn the push to get their NGN networks up and running, many providers took a short cut. They deployed their VoIP networks as a loose collection of elements interconnected by direct signaling links. Unlike SS7 and Internet protocol multimedia subsystem (IMS), which are hierarchical networks, there’s no signaling and session layer to handle application-layer tasks. From a signaling perspective, each network element must handle all application-layer related tasks. Every possible route must be defined at each network element, creating a spider web of logically connected SIP nodes.

Creating a Session-Control Layer in NGNsCreating a signaling and session framework in the core NGN network avoids the pitfalls created by point-to-point routing. By deploying a SIP signaling router (SSR) - a SIP proxy with enhanced routing capabilities - operators can centralize layer-5 SIP routing in the core network and relieve endpoints of session-management tasks. The resulting architecture creates a flexible framework that enables the following use cases:
Enhanced application server (AS) selection: The tight coupling between endpoints like SIP phones and SIP application servers creates a challenge for many operators. Changes made to the physical network, such as adding a new application server, have a direct impact on the way SIP phones access service. The SSR shields the endpoints by decoupling them from direct knowledge of the changing network. The SIP phones just have to be configured with a single abstract address. Endpoints send requests to the SSR, which resolves the address to the appropriate SIP AS platform and routes the request to that platform.

SIP trunking: Softswitch-based, SIP-trunking solutions, which are built on a “per-connection” cost model, can become costly very quickly. And, since softswitches usually are deployed with the switch vendor’s choice of application server, it’s difficult to gain the economy of a “best-of-breed” solution. By implementing a SSR, operators can use a session-based approach to provide fixed-line services to enterprise customers. The SSR routes on-net calls between IP PBXs and off-net calls through a public switched telephone network (PSTN) gateway to local and long-distance fixed numbers. The resulting architecture creates a volume-based cost structure and reduces costs by allowing operators to select “best-of-breed” application servers.
SIP number portability (NP): For operators with a SIP-trunking infrastructure, performing number portability for VoIP calls can present a particular problem. They can simply “dump” the calls on the PSTN gateway if there’s enough intelligent network capacity and the terminating network is time division multiplexing (TDM). But, if the terminating number is another IP PBX or belongs to a VoIP operator, the call must be shuttled from VoIP to TDM and back to VoIP again. Running pure VoIP calls over TDM wastes gateway capacity and degrades voice quality. Another alternative is to replicate a number portability solution in the SIP domain, but that’s a costly approach. Using the SS7 access feature of the SSR, operators can make TDM-NP available to the SIP network. This capability allows the SSR to augment its routing capabilities with SS7 data. Pure VoIP calls don’t have to be shuttled over the TDM network to perform NP, which maintains voice quality and saves PSTN gateway capacity.

Centralized SIP proxy: Expanding NGN networks requires the addition of new softswitches. Each new piece of equipment must be provisioned with the routing entries for all of the existing softswitches, and existing softswitches must be updated with the routing entries for new equipment. Route management, which is based on pre-defined SIP trunks, becomes increasingly complex as the network expands. Service and subscriber data are tightly coupled with the softswitch, making it difficult to change an existing service or add new applications uniformly. The SSR deployed as a SIP proxy creates a SIP-based reference architecture over the existing network. Calls are routed by default from the softswitch to the SSR. The SSR makes layer-5 SIP routing decisions based on advanced routing algorithms and forwards the request to the appropriate SIP destination.

Specialized SIP proxy: As operators consolidate their networks, many are discovering that softswitches supplied by different vendors are unable to establish sessions. That’s because each vendor uses a different SIP implementation. As long as an operator deploys equipment from a single vendor, there’s no problem. But, when equipment from another vendor is introduced, interoperability problems arise. The issue can be resolved with a customized solution, but that’s an expensive route to take. The SSR creates an architectural solution that is independent of the endpoints and eliminates interoperability problems. Deployed in the signaling layer, the SSR serves as a SIP proxy. It routes SIP traffic between the softswitches and serves as a mediation point between them, “fixing” protocol variations on the fly.

SummaryHaving softswitches and other endpoints perform layer-5 session management may be sufficient for fairly small deployments and simple management tasks. But, as the network expands, the lack of a capable session framework introduces a host of network issues. A suitable session framework offloads signaling and session tasks from the edge next-gen elements to enable efficient network expansion. Just as core routers are used to minimize the routing burden on IP endpoints, layer-5 SIP routing reduces the burden on endpoints by centralizing session management tasks at the network core. The resulting architecture can expand systematically to support VoIP subscriber growth, deliver advanced multimedia services and create the foundation for future technologies and services.

Broadband Economic Stimulus Plan

Interesting article from WSJ Blog

By Amy Schatz
Differences between the two broadband stimulus proposals working their way through Congress could take a little while to work out, but details of the plans that have popped up this week offer a map of where things might end up. The House and Senate haven’t agreed on much about the broadband stimulus so far, neither the cost ($6 billion in the House, $9 billion in the Senate) nor Internet speeds (“advanced broadband” in the House clocks in at 45mbps, while the Senate says “next-generation” broadband is 100 mpbs). Cable operators aren’t thrilled about language in the House and Senate bills, which sets aside grant money for broadband providers who can provide 100 mbps service, since that would tend to favor phone companies installing fiber-to-the-home service.

House lawmakers would hand out $6 billion in broadband grants. Half would be given out by the U.S. Department of Agriculture without speed requirements, although 75% of the money has to be used in “rural area(s) without sufficient access to high-speed broadband service.”
A quarter of the grant money handed out by the Commerce Department would be for “basic” broadband service (a.k.a 5 mbps download/1 mbps upload) to “un-served” areas while the rest would go for “advanced” broadband service (a.k.a 45 mbps/15 mbps) in “underserved” areas. Wireless providers would need to offer Internet service with a download speed of at least 3 mbps and upload of 1 mbps.

The House would leave it up to the FCC to decide how to define un-served and underserved areas. Senators want $9 billion in broadband, half of which would be set aside for providing service in rural areas. The Senate Finance Committee tacked on limited tax credits of 10% or 20% to providers offering “current generation” (a.k.a. 5 mbps/1 mbps) service in rural areas and 20% credit for “next generation” (a.k.a. 100 mbps/20mbps) service in rural or low-income areas. The tax credits are relatively small, estimated to cost about $110 million over 10 years.
Open access, or net neutrality, conditions could be a major sticking point for phone and cable companies, which don’t want significant government constraints on their network management practices. Right now, companies are concerned about how “open access” might be defined in the legislation.

In the House, lawmakers say the FCC would be required to define “open access” within 45 days of the legislation’s passage. Senate lawmakers say their grants would be dependent on “interconnection and nondiscrimination requirements,” although they spell out what that means.
The broadband spending would also fall on the long-term side of benefits which may came from the economic stimulus plan.

The Congressional Budget Office said Wednesday that much of the spending on broadband wouldn’t really have much of an impact on consumers for several years. It could take “up to five to seven years” to finish some projects funded by the $2.8 billion handed out by the Agriculture Department’s rural development broadband program.

Stimulating the Growth of Fiber Networks Will Immediately Create Maximum Broadband Jobs

Adopting tax incentives for expanding next-generation broadband networks with direct fiber connections would ensure that the economic recovery package now under consideration in Washington, D.C., would create a large number of jobs and extensive economic growth, according to a study released recently by the Fiber-to-the-Home Council.

The study, prepared for the FTTH Council by the economic consulting firm Empiris LLC, found that enactment of tax incentives for the deployment of networks running fiber all the way to premises would generate more than 200,000 direct jobs in each of the next 3 years and increase economic output by more than $100 Billion. A key reason for these substantial job benefits is that labor accounts for almost one-half of the money spent to deploy networks with direct fiber connections. In addition to the direct effects, increased broadband penetration from these proposals would indirectly generate another 360,000 new jobs, according to the report.
The report emphasized that, because broadband providers are experienced infrastructure builders, these and other tax incentives for new next-generation broadband infrastructure would create jobs and spur economic growth almost immediately. "Not only would these proposals create jobs and help boost economic recovery right away, but they will also accelerate expansion of the basic high-tech infrastructure that will drive the U.S. economy throughout the 21st Century," said Jeffrey A. Eisenach, Chairman and Managing Partner at Empiris.
The Empiris study estimates that federal payment of bond interest for next-generation broadband networks, officially referred to as "tax credit bonds", would create 197,437 direct U.S. jobs as a result of private sector deployments, and another 19,744 direct jobs in public sector deployments in each of the next 3 years. Meanwhile, a 100 percent expensing provision for next-generation broadband would produce as many as 32,000 jobs over the same period, while a 50 percent expensing provision for rural/underserved areas would potentially create more than 5,000 jobs.

In rural and underserved areas, the FTTH Council supports tax incentives for broadband deployment at slower speeds to ensure that all Americans have access to broadband and to stimulate broadband deployment and economic activity in areas where they otherwise would not occur.

"In expanding America's broadband infrastructure, it makes sense to encourage the higher-bandwidth networks we will need to compete globally in decades to come," said Joe Savage, President of the FTTH Council. "This study provides evidence that promoting those networks also will give the maximum boost to employment and immediate economic growth."
The FTTH Council recently endorsed broadband incentives proposed by the Communications Workers of America, including provisions similar to those analyzed in the Empiris paper.

Convergence Part Deux

We've all heard of convergence in Telecom applications before, but we're looking at a whole new level now. It's just a matter of time until all out Telecom services are delivered ny a high speed broadband ethernet connection. TV, Interent, Telephone and even cell phone applications are all combining in our high speed broadand service. DSL, Cable Interent or FiOS service will be part of the convergence and the applications that go with them will be outstanding.

Economic Stimulus Package through Telecom Infrastructure

Found this interesting article. In order to stay copetitive in the global economy we need to continue to build the broadband infrastructure and availability in this country.

Investment in 100 (Mbps) NetworkSource:
www.freepress.net

According to a new new report issued by the Freepress Action Fund, President-elect Obama and congressional leaders have concluded that a massive economic stimulus package focused on infrastructure is the best hope for pulling the U.S. economy out of the current recession. In the past, such stimulus efforts traditionally focused on highways and utilities, and these types of projects certainly belong in the new stimulus package. However, the incoming Obama administration and Congress must look beyond the interstate highways and start investing in the information superhighway. Just as President Eisenhower's economic policies brought Americans a national transportation system in the 1950s, President Obama's can connect Americans to a communications network fast becoming the foundation of the 21st Century economy.

Promoting the deployment of a national, forward-looking broadband infrastructure will provide substantial short-term and long-term economic benefits. This deployment effort will immediately create tens of thousands of new jobs in the telecommunications, manufacturing and high-tech sectors. In turn, a new, world-class broadband infrastructure will spark the creation of millions more jobs in nearly every economic sector connected to technology and communications.
In particular, these policies will provide substantial economic relief to the rural areas of America hit hardest by the current recession. They will also improve our global competitiveness, lifting us from 15th place (or by other measures, 22nd place) among developed nations in broadband adoption. Increased broadband adoption - particularly if targeted to low-income users and households with school-age children - will also substantially increase short-term consumer spending. And it will ensure long-term economic growth by bringing those on the wrong side of the digital divide into the digital economy.

Though the Internet was born here, American consumers are not benefiting from broadband's full potential because our networks are slow and expensive compared to the rest of the world. This is largely because there is no meaningful competition in the American broadband marketplace, and network operators have no incentive to make substantial long-term investments. Broadband stimulus funding should only be used to build world-class networks unlikely to be deployed absent public investment. Freepress Action Fund recommends that stimulus funds be targeted at deploying broadband services capable of delivering actual (not advertised) speeds in excess of 100 Megabits per second (Mbps) in both upstream and downstream directions.

A broadband stimulus package must be carefully targeted and tied to public service principles that ensure that American taxpayers get a strong return on their investment. In this paper, Freepress Action Fund offers a set of proposals to expand the debate about broadband stimulus and provide a foundation for further discussion.

Freepress Action Fund focuses on a set of key public policy priorities:
- Rural America — building out future-proof networks to unserved areas.
- Low-income users — supporting affordable broadband connections, computers and tech training.
- Global competitiveness — upgrading our urban infrastructure to meet world-class standards.
- Education — promoting children's access to technology at school and at home.
- Accountability — ensuring clear standards of quality, affordability and competition, and deduct up to $200 in qualifying Internet access device expenditures.

Broadband Data Improvement Act Funding($300 million over 3 years)
Congress recently passed legislation to promote broadband deployment and adoption by mapping broadband availability through the collection of comprehensive data. However, no money was appropriated to implement the programs established in the bill.
By funding the public/private programs envisioned by this already approved effort, Congress can ensure that broadband stimulus funding is directed to the areas where it is needed most.
Rural Development Community Connect Grant Program ($150 million over 3 years)
Congress should appropriate $50 million per year over three years to this USDA-led program for the explicit purpose of constructing and/or funding community centers (including libraries) that will offer free broadband services and technology training, with an emphasis on training for families with children and senior citizens.

Health Care and Public Service Digital Modernization Program ($150 million over 3 years)
President-elect Obama has expressed the desire to use the stimulus legislation to increase efficiency in our nation's health care system by bringing record-keeping and other health care services into the digital age. There is a similar need to modernize the customer service systems at local and state governmental agencies. Such modernization would vastly improve productivity in the general economy, replacing long lines with easy-to-navigate, Web-based service portals. Congress should establish a program, overseen by the NTIA, that supports modernization at health care facilities and local and state agencies.

Oversight, Accountability and Results
Though the stimulus is needed quickly, and though it is almost certain that legislation will be crafted in haste, Congress must not simply write blank checks to industry. To maximize the effectiveness of scarce taxpayer resources, oversight and accountability measures must be established. If the public is to become a financial partner in our broadband networks, the private owners of those networks must be held to public service standards.
In particular, mechanisms should be established to ensure that any tax incentives or grant monies are used to fund new broadband deployment projects. This requirement will ensure that the stimulus funds are used to create new jobs, not to prop up the stock prices of telecommunications companies.

All of the grant programs and tax policies we recommend must be available to all telecommunications providers, including municipalities, nonprofits, and non-incumbent carriers.
Further, stimulus money must be tied to strict build-out schedules and affordability and capacity requirements. This level of public investment should return a network that is world-class — not simply an incremental improvement over the status quo. The Internet service these subsidies are designed to support also must be an open, freely competitive platform for ideas and commerce.

Job Cuts in Telco

Here the first of many annouced and un-annouced job cuts in the Telelcom sector. As the economy slows, Telco will feel the pinch. Hopefully not as much as other sector because Telecom services can help the bottom line by increasing efficiency and allowing employees to do more with less.


Massive job cuts at BT, but Q2 results solid
By Mary Lennighan, Total Telecom
13 November 2008
U.K. incumbent to shed 10,000 jobs; outlines plans for turning around troubled Global Services unit.
The news that BT plans to cut 10,000 jobs as part of an existing cost-reduction programme overshadowed a largely solid second-quarter results announcement from the U.K. incumbent on Thursday.

BT executives outlined their plans to turn around the ailing Global Services unit, a task that will centre on cutting costs and reducing bespoke contracts, and let slip that the unit signed a big U.K. contract yesterday. There could also be more outsourcing on the cards. But, as Livingston predicted in his presentation, Thursday's headlines will likely focus on the planned headcount reduction. The telco plans to shed a total of 10,000 positions this financial year, 4,000 of which have already gone. The remainder will largely affect indirect employees, that is agency staff, contractors, subcontractors and offshore workers.

Touch Screen Starbucks Tables & GPS Dog

As we move forward with ever increasing technology and bandwidth requirements here are a couple interesting new applications. A bit off-beat, but ya just never know what creative folks will come up with next. http://sharptelco.com/


Totally Trivial: Mad scientists
By Nick Wood , Total Telecom
22 October 2008

The South Korean operator made its first foray into fantastical furniture at a special branch of Starbucks, which will use the touch-screen sporting table, equipped with advanced mobile technology, to allow customers to order and pay for items on the coffee shop's menu."Traditionally, Starbucks customers order and pay at cashier counters," said SK Telecom, in a statement that sent shockwaves through no one."Once customers select and pay for items from the 'Ubiquitous Table', the order information is immediately transmitted via mobile technology to the store's system. As soon as the order is ready, a message appears on the screen of the 'Ubiquitous Table'."The all-pervading furniture has so far been limited to one pilot store in South Korea, and as yet there are no details on a wider rollout.On a related note, rumours that Steven Spielberg is in talks with Paramount to produce 'Attack of the Ubiquitous Tables', have just been started by us.

Putin equips dog with sat navRussian Prime Minister Vladimir Putin has put a collar containing satellite-guided positioning technology on his black Labrador, Koni, reports the Associated Press.The former president asked one of his deputies Sergei Ivanov for the device to help him keep tabs on his beloved dog, which is not the most unusual request from someone who used to work for the KGB."She's wagging her tail, she likes it," said Putin, in the report.The device goes into standby mode when the dog isn't moving, "if it, say, lies down in a puddle," said Ivanov, or gets squashed by an armoured car, said Nick Wood.The system itself doesn't use the US Global Positioning System (GPS), but instead relies on the Russian-developed Global Navigation Satellite System, or GLONASS for short.However, while Russia may have beaten the U.S. to blasting a dog into space when it launched the ill-fated Laika in 1957, it still trails in the deployment of navigation satellites: GLONASS is unable to provide worldwide coverage – it currently has 21 satellites in orbit, but needs 24.Still, Ivanov is doggedly determined (pun 100% intended), and claims the system will be extended to the rest of the planet by the end of 2009.

Offices Buildings - a thing of the past?

Do we need office buildings anymore? As data services from T1 or DS1 to GigE continue to become more prevalent in the network the pricing of these advance data services will continue to drop. So what good is an office anymore? Do we need physical interaction? I often Instant Message people in the cubes adjacent to mine instead of talking. We just starting to see 100 Gigabit Ethernet Service tested in the Network. We can only imagine the possibilities of the applications that will be coming down the pipe to use that bandwidth. It could be entire new conferencing application to see and speak to coworkers as easily and quickly as we use instant messaging services now. Consider how much fuel could be saved if the majority of the work force worked from home, not to mention the benefits to the environment. Productivity and Accessibility are always questions when people want to want work from home. I believe given enough bandwidth and the right applications it will be nearly seamless to determine if a person is home or at the office.

100 Gigabits per second Bandwidth!!

This is really a big deal to transport 100 Gbps on not a single fiber but one wavelength on a fiber. That means other wavelengths on that single piece of glass are transporting other high bandwidth services! This breakthrough continues the bandwidth revolution that will fuel our nations economic recovery.

BASKING RIDGE, N.J., Sept. 25 /PRNewswire/ -- Verizon and Nokia Siemens Networks have taken a step closer to being able to transmit commercial traffic at a speed of 100 gigabits per second (Gbps). The two companies carried out a successful 100 Gbps transmission on a single wavelength for more than 1,040 kilometers over field fiber, setting a new distance record and demonstrating better performance than conventional transmission.
The field trial, conducted on optical fiber on the Verizon network in north Dallas, successfully proved that 100 Gbps signals can be simultaneously transported with 10 Gbps and 40 Gbps signals on the same system with superior results by using advanced optical techniques.
The Nokia Siemens hiT 7500 ultra-long-haul, dense-wavelength-division-multiplexing platform -- combined with multi-level modulation, polarization multiplexing and coherent detection -- allowed the signal to be carried over ultra-long distances at high-data rates with significantly better chromatic dispersion and polarization-mode-dispersion tolerances than conventional systems.

What is Gigabit Ethernet?

Gigabit Ethernet Service (GigE) is a fiber-based network service that utilizes a high speed backbone to provide customers with LAN Interconnection between multiple locations at the native Gigabit Ethernet LAN speeds in specific geographical locations. GigE service delivers a full duplex interface conforming to Gigabit Ethernet standards(1000BaseSX, 1000BaseLX) directly to the customer's LAN. The Telco Company will deploy equipment in the customer's serving central office and connect them using a high speed backbone. This backbone will consist of multiple Gigabit Ethernet trunks. Depending on the customer's location, the backbone may be shared by several customers connected to this service. GigE service provides data privacy and security through the use of 802.IQ closed user groups. Users in a group can only access their own data. Customers will connect to the C.O. equipment using fiber optic LAN extension equipment located on their premises. This, equipment, which is owned by Telco Company, will be the network interface for this service. The customer interface is a single mode or multimode fiber optic connection providing ethernet at 1 gigabit per second. If the facility has extensive bandwidth requirements, GigE is often the most cost-effective option for bandwidth and reliability.

Is Ethernet the new Telecom Backbone Circuit?

Growing up as Telco Dog for 20+ years, OK maybe even becoming an old Telco Dog, T1's or DS1's have been the Telecom backbone for as long as I can remember. T1's are used to connected PSTN (public switched telephone network) switches together, T1 Circuits connect PBX's and key systems to the PSTN network, T1's are the primary means of transporting most Internet circuits across the globe. Granted there are OC3's OC12's and many other faster bigger pipelines that carry data communications around the globe, but all those circuits use T1's as the building blocks for those faster circuits. An OC3 backbone carrier circuit is really 84 1.544mb T1's packaged together. We're finally seeing a new kid emerge on the block and that's Ethernet business service. The telco world is starting to embrace Internet Protocol connectionless architecture, where instead of massing together groups of 24 64kb voice circuits to make a T1 Circuit and them massing together those T1's into bigger pipes, Ethernet service is true bandwidth and is available by what the customer needs for their business. Ethernet allows the business to directly plug-in to the Internet Cloud reducing equipment required which dramatically reduces cost per Meg or Gig of bandwidth. Naturally Ethernet for business is a new product and just like early T1's, are only available in limited areas. T1's today are available everywhere, and eventually Ethernet Business service will be too. To see if Ethernet Service is available at your location check out ShorForEthernet.Com

T1 Pricing for your Business

There are so many small businesses operating today on DSL, which is OK if for a small office or work at home situation. DSL and cable internet are both great, extremely cost effective solutions when price is the most important consideration. However when your business grows out of a home office to where you depend on internet and phone service to make money and when your DSL or cable internet goes out you're losing money, then it's time to upgrade to a reliable robust T1 or DS1 circuit for you office. T1 Pricing continues to drop as competition increases among telecom carriers. $300 to $400 a month sounds like a lot to many people, but what most need to consider is that T1 line will also provide your phone service. If you have 5-6 business telephone lines and internet service, frequently you can save money by bundling your telephone lines and internet service on the T1 Line. When you consider T1 lines are ultra-reliable and monitored 24x7 for performance, T1 Pricing becomes a great value for the expanding business.

How Much Bandwidth is Enough?

We're well into the 21st century, we've become an information society. I can't believe the information that is literally at my finger tips at any time of the day or night. One of my passions is motorcycles. I'm starting a project to add a fairing to my Valkyrie motorcycle. I found an old piece of junk Batwing Harley fairing at a swap meet for a couple bucks and picked it up. In the old days, I would have had a very difficult time finding the other parts to mount it to my bike by using shoe leather and the telephone. Truth be told, I probably wouldn't be successful unless I got really lucky and found someone friendly and very knowledgeable to help. Today it took me less than 20 minutes to research that it was 70's era FLH Shovelhead fairing along with a parts breakdown of the mounting brackets required to mount it. Then a quick check of ebay revealed the project could be done. Wow! I have a 5 megabyte Verizon FiOS link to my house. T1 Pricing continues to drop every month where you get an ultra-reliable 1.5 megabyte guaranteed up and down stream broadband link that's monitored 24 hours a day. The next jump for commercial broadband service is direct Ethernet connections of 10 to 30 Gigabyte data rates at very competitive rates with T1 Reliability. As more and more applications use the worldwide data network, DSL Availability residential Internet services data rates of 50 Megabytes will become common in the next couple years. Can't wait to see the applications that be common for children! More news and information at SharpTelco.Com

Ethernet Service for Business

The telecommunication companies are making a giant strides for busineses that need large amounts of bandwidth at a resonable price. Instead of the traditional T1, DS1 or even DS3 Service carriers are starting to provide (up to) 10GB Ethernet Service directly to the business. The catch is the business needs to be located close to the carriers existing fiber backbone. Those clever engineers at Shop for T1 have come up with a new service to allow business customers to search for Ethernet Service and Pricing by their location to see if 10GB Ethernet service is a viable option.

Telecommunications Future?

Where is the Public Telecommunication Network going in the next 5-years, 10-years? I started to say, the sky's the limit; but as I'm typing I realize that is probably not true. We already have access to Hubble Telescope images on our computers! We see amazing new services everyday being made available to anyone with a broadband connection. I was looking at an aquarium on ebay and found I could configure a text message to my cell phone to remind me to check before the bidding ended. I've read some article that 40-50 Mb services are not uncommon to homes in certain parts of Asia. It just keeps going and going.

I made a giant step this year and am only keeping one yellow pages book. In our area, we get 5 to 7 different books from different publishers all covering slightly different areas and having different advertisers. I used to dutifully stack them up, in case I needed to find something. I've done this for the past two years and never used them at all. Everything I've needed I've found faster and easier using the internet. This year as they landed on the front porch, they went straight to the recycle bin - except one... I'm having a hard time letting go of that last one - maybe next year!

Telecommunications History

Where is telecommunications going in the next five years? Let's look at the history of telecommunications and see if we can learn some lessons to help us build on the foundation of events past.
Electronic communications started with the simple teletype whereby current traveled along a cable and opened and closed a relay. By using a code of short and long relay closures or dots and dashes which became known as "Morse Code" a message code passed along a wire. This was the first major technological communication advance and it was huge. Instead of days or weeks for a message to make it across a state or country using the pony express; the message could be recieved in a matter of minutes or hours to decode the message and have it delivered locally.
The next advance in electronic communication was the ability to pass voice on the wire instead of the impersonal dots and dashes. This also made communication available to anyone instead of those skilled in the use of Morse Code. This advancement was possible because the discovery of pulse code modulation. In a nutshell, pulse code modulation takes a sampling of the multitude of tones made the human voice and transforms those tones into pulse or many dots and dashes! These pulses could transmitted relatively long distance on copper wire and the CODEC reassembles the pulse back into an excellent representation of human speech.
