AT&T Ends Bid to Add Network Capacity Through T-Mobile USA Purchase December 19, 2011

Posted by admin in : AT&T, Local News and Events, T-Mobile , add a comment

DALLAS–(BUSINESS WIRE)–AT&T Inc. (NYSE: T) said today that after a thorough review of options it has agreed with Deutsche Telekom AG to end its bid to acquire T-Mobile USA, which began in March of this year.

The actions by the Federal Communications Commission and the Department of Justice to block this transaction do not change the realities of the U.S. wireless industry. It is one of the most fiercely competitive industries in the world, with a mounting need for more spectrum that has not diminished and must be addressed immediately. The AT&T and T-Mobile USA combination would have offered an interim solution to this spectrum shortage. In the absence of such steps, customers will be harmed and needed investment will be stifled.

“AT&T will continue to be aggressive in leading the mobile Internet revolution,” said Randall Stephenson, AT&T chairman and CEO. “Over the past four years we have invested more in our networks than any other U.S. company. As a result, today we deliver best-in-class mobile broadband speeds – connecting smartphones, tablets and emerging devices at a record pace – and we are well under way with our nationwide 4G LTE deployment.

“To meet the needs of our customers, we will continue to invest,” Stephenson said. “However, adding capacity to meet these needs will require policymakers to do two things. First, in the near term, they should allow the free markets to work so that additional spectrum is available to meet the immediate needs of the U.S. wireless industry, including expeditiously approving our acquisition of unused Qualcomm spectrum currently pending before the FCC. Second, policymakers should enact legislation to meet our nation’s longer-term spectrum needs.

“The mobile Internet is a dynamic industry that can be a critical driver in restoring American economic growth and job creation, but only if companies are allowed to react quickly to customer needs and market forces,” Stephenson said.

To reflect the break-up considerations due Deutsche Telekom, AT&T will recognize a pretax accounting charge of $4 billion in the 4th quarter of 2011. Additionally, AT&T will enter a mutually beneficial roaming agreement with Deutsche Telekom.

AT&T defends T-Mobile deal in response to DOJ suit September 11, 2011

Posted by admin in : AT&T, T-Mobile , add a comment

WASHINGTON (AP) — AT&T is countering the U.S. government’s attempt to block its $39 billion acquisition of T-Mobile by depicting the deal as a way to provide consumers with better cell phone service at lower prices.

The argument, submitted in a Friday court filing, is AT&T Inc.’s first legal response to a lawsuit that the Department of Justice filed last week in an effort to ensure T-Mobile remains independent. AT&T’s 25-page document echoed the company’s previous contention that buying rival T-Mobile will enable it to expand its mobile communications network so there are fewer dropped connections in a world where constant online access is becoming the norm.

The Justice Department believes there wouldn’t be enough competition if AT&T devours T-Mobile, creating a void that would increase prices and reduce the incentive to develop new technology.

AT&T’s lawyers contend that the Justice Department’s analysis reflects a misunderstanding of the market. They say T-Mobile, the fourth largest cell phone carrier with 33.6 million customers, isn’t a significant competitive threat to AT&T, the No. 2 carrier with nearly 100 million customers. T-Mobile has been losing market share in recent years, a trend that AT&T argues will discourage its German parent, Deutsche Telekom, from investing to improve its own wireless network.

In contrast, AT&T says it spent more than $30 billion in network upgrades from 2008 through 2010, yet still can’t keep up with customers’ growing demand to transfer data over phones and other wireless devices, according to the court documents. But if it can snap up T-Mobile, AT&T believes the added capacity will put it in a better position to deliver better services. AT&T already has pledged to invest at least $8 billion and transfer 5,000 jobs currently in overseas call centers back to the U.S. if the T-Mobile purchase goes through.

The court filing also seeks to counter the Justice Department’s theory that the U.S. cell phone market would be dominated by just three carriers — AT&T, Verizon Wireless and Sprint Nextel Corp, if T-Mobile disappears from the market. AT&T’s filing cites "innovative upstarts" MetroPCS and Leap/Cricket and regional carriers such as US Cellular and Cellular South as viable alternatives for most consumers.

"The (Justice) Department does not and cannot explain how, in the face of all these aggressive rivals, the combined AT&T/T-Mobile will have any ability or incentive to restrict output, raise prices, or slow innovation," the AT&T’s lawyers wrote.

It’s unusual for the Justice Department to challenge a proposed acquisition in court. Most companies back out of deals to avoid tangling with the government. But AT&T has a huge incentive to fight: It will have to pay a $3 billion termination fee if its agreement with T-Mobile unravels.

The first hearing in the case is set for Sept. 21 in Washington before U.S. District Court Judge Ellen Huvelle.

AT&T, which is based in Dallas, is seeking a quick resolution to the case.

AT&T, T-Mobile pledge to bring 5,000 jobs to US August 31, 2011

Posted by admin in : AT&T, T-Mobile , add a comment

Joelle Tessler, AP Technology Writer, On Wednesday August 31, 2011, 9:55 am EDT

WASHINGTON (AP) — AT&T Inc. is pledging to bring 5,000 wireless call center jobs, currently based abroad, back to the U.S. if it is allowed to proceed with its proposed $39 billion acquisition of T-Mobile USA.

The company is also promising that the merger would not result in any job losses for AT&T and T-Mobile USA wireless call center employees who are on the payroll in the U.S. when the deal closes.

AT&T’s commitment to repatriate jobs comes as antitrust regulators at the Federal Communications Commission and the Justice Department ramp up their reviews of a combination that is certain to reshape the wireless industry’s landscape.

AT&T, the nation’s second-largest wireless carrier, is seeking government approval to buy T-Mobile USA, the fourth-largest, from Germany’s Deutsche Telekom AG. The cash-and-stock transaction would catapult AT&T past Verizon Wireless to become the nation’s largest wireless provider, and leave Sprint Nextel Corp. as a distant number three.

Although AT&T said it has not yet determined where the new U.S.-based jobs would be located, it promised they would offer "highly competitive wages and benefits." The company hopes this message will carry weight in Washington, where job creation is a top priority for the Obama administration as the nation faces the possibility of a recession heading into the 2012 election.

"At a time when many Americans are struggling and our economy faces significant challenges, we’re pleased that the T-Mobile merger allows us to bring 5,000 jobs back to the United States and significantly increase our investment here," AT&T Chairman and Chief Executive Randall Stephenson said in a statement.

Beyond the call center operations, AT&T has said it does anticipate some workforce duplication after the deal closes, but expects to make reductions largely through natural attrition.

Opponents of the proposed merger, including public interest groups and Sprint, insist it will lead to fewer choices and higher prices for consumers by eliminating a carrier that offers lower rates and less expensive plans than competitors. They also fear the deal could jeopardize Sprint’s future as an independent company and ultimately lead to a wireless industry duopoly.

AT&T and T-Mobile argue that the acquisition would benefit consumers. They say it would lead to fewer dropped and blocked calls and faster mobile Internet connections for subscribers by allowing the companies to combine their limited wireless spectrum holdings at a time when both are running out of airwaves to handle mobile apps, online video and other bandwidth-hungry services.

They also say the transaction would position AT&T to cover more than 97 percent of the U.S. population with its new high-speed, fourth-generation wireless service.

Finding more airwaves to keep up with the explosive growth of wireless broadband services and ensuring that all Americans have access to high-speed Internet connections are both top priorities of the FCC and the Obama administration.

E911 – Saves Life! December 30, 2010

Posted by admin in : AT&T , add a comment

Enhanced 9-1-1.

Enhanced 911, E-911 or E911 is a North American telecommunications based system that automatically associates a physical address with the calling party’s telephone number, and routes the call to the most appropriate Public Safety Answering Point (PSAP) for that address. The caller’s address and information is displayed to the calltaker immediately upon call arrival. This provides emergency responders with the location of the emergency without the person calling for help having to provide it. This is often useful in times of fires, break-ins, kidnapping, and other events where communicating one’s location is difficult or impossible.

The system only works in North America if the emergency telephone number 911 is called. Calls made to other telephone numbers, even though they may be listed as an emergency telephone number, may not permit this feature to function correctly. Outside Canada and the United States this type of facility is often called caller location, though its implementation is dependent on how the telephone network processes emergency calls. Typical architecture diagram:



The first 911 system was installed in Haleyville, Alabama, in February 1968 as a way to quickly connect a subscriber to the local police station. This system did not identify the caller but did provide a means to access emergency services that had not previously been available. This system was quickly adapted and improved by other telephone companies to become the E911 system which provides both caller location and identification. A pioneering system was in place in Chicago by the mid-1970s, providing both police and fire departments access to the source location of emergency calls. Enhanced 911 is currently deployed in most metropolitan areas in the United States and Canada.

Public safety answering point (PSAP)

The final destination of an E911 call (where the 911 operator sits) is a Public Safety Answering Point (PSAP). There may be multiple PSAPs within the same exchange or one PSAP may cover multiple exchanges. The territories (Emergency Service Zone) covered by a single PSAP is based on the dispatch and response arrangements for the fire, police, and medical services for a particular area. Most PSAPs have a regional Emergency Service Number (ESN), a number identifying the PSAP.

The Caller Location Information (CLI) provided is normally integrated into emergency dispatch center’s computer-assisted dispatch (CAD) system. Early CAD systems provided text display of the caller’s address, call history and available emergency response resources. In 1994, working in cooperation with the emergency response agencies of Covington, KY, 911 Mapping Systems, Inc.[1] founded in 1992 by Robert Graham Thomas Jr.,[2] implemented the first real-time on-screen E911 street map display to highlight the caller’s position, nearest available emergency responders and other relevant information such as fire hydrants, hazardous materials and/or other data maintained by the city. Shortly thereafter, integrated mapping became a standard and integral part of all CAD systems and continues to evolve alongside 911 response technology. For Wireline E911, the location is an address. For Wireless E911, the location is a coordinate. Not all PSAPs have the Wireless and Wireline systems integrated.

Interconnection details

Each telephone company (local exchange carrier, or LEC) has at least two redundant DS0-level (that is, 64 kbit/s, or voice quality) trunks connecting each host office telephone switch to each call center. These trunks are either directly connected to the center or they are connected to a telephone company central switch that intelligently distributes calls to the PSAPs. These special switches are often known as 911 Selective Routers. Their use is becoming increasingly more common as it simplifies the interconnection between newer ISUP/SS7-based host office switches and the many older PSAP systems.

If the PSAP receives calls from the telephone company on older analog trunks, they are usually Pulse driven circuits. These circuits are similar to traditional telephone lines, but are formatted to pass the calling party’s number (Automatic Number Identification, ANI). (For historical reasons, the PSAP will refer to these as CAMA circuits even though Centralized Automatic Message Accounting (CAMA) is actually a reference to the call log.)

If the PSAP receives calls on older-style digital trunks, they are specially formatted Multi-Frequency (MF) trunks that pass the calling party’s number (ANI) only. Some of the upgraded PSAPs can receive calls on ISUP trunks controlled by the SS7 protocol. In that case, the calling party’s number (ANI) is already present in the SS7 setup message. The Charge Number Parameter contains the ANI.

Wireline enhanced 911

When a call is placed to 911, the source of the call is recorded (allowed by special privacy legislation). The source number is used to look up the ESN (phone number) of the appropriate call center (PSAP) in a database and connect the call.

Address information is not passed along by the public phone network; only the calling party’s phone number is passed. The PSAP uses the calling party number to look up the address in the Automatic Location Identification (ALI) database. The ALI database is secured and separate from the public phone network by design. It is generally maintained by the Incumbent Local Exchange Carrier (ILEC) under contract by the PSAP. Each ILEC has their own standards for the formatting of the database.

Most ALI databases have a companion database known as the MSAG, Master Street Address Guide. The MSAG describes the exact spelling of streets, street number ranges, and other address elements. When a new account is created, the address is looked up in the Master Street Address Guide to find the appropriate Emergency Service Number that 911 calls from that phone number should be routed to. Competitive local exchange carriers (CLEC) and other competing wireline carriers negotiate for access to the ALI database in their respective Interconnect Agreement with the ILEC. They populate the database using the ILEC MSAG as a guide.

ALI Failure is when the phone number is not passed or that the phone number is not in the ALI database. If this happens, the call is passed to the trunk group’s default ESN, which is a PSAP designated for this function. The PSAP operator must then ask the incoming call for their location and redirect them to the correct PSAP. The legal penalty in most states for ALI database lookup failure is limited to a requirement that the telephone company fix the database entry.

Wireless enhanced 911

The billing address associated with a cell phone is not necessarily the location to which emergency responders should be sent, since the device is portable. This means that locating the caller is more complicated, and there is a different set of legal requirements.


The U.S. Federal Communications Commission (FCC) has several requirements applicable to wireless or mobile telephones:[3]

Location information is not only transmitted to the call center for the purpose of sending emergency services to the scene of the incident, it is used by the wireless network operator to determine to which PSAP to route the call.


A second phase of Enhanced 911 service is to allow a wireless or mobile telephone to be located.

To locate a mobile telephone geographically, there are two general approaches. One is to use some form of radiolocation from the cellular network; the other is to use a Global Positioning System receiver built into the phone itself.

Radiolocation in cellular telephony uses base stations. Most often, this is done through triangulation between radio towers. The location of the caller or handset can be determined several ways:

The first two depend on a line of sight, which can be difficult or impossible in mountainous terrain or around skyscrapers. Location signatures actually work better in these conditions however. TDMA and GSM networks such as T-Mobile 2G use TDOA.[7] AT&T Mobility initially advocated TDOA, but changed to embedded GPS in 2006 for every GSM or UMTS voice-capable device due to improved accuracy.

CDMA networks tend to use handset-based radiolocation technologies, which are technically more similar to radionavigation. GPS is one of those technologies. Alltel, Verizon Wireless, T-Mobile 3G, and Sprint PCS use Assisted GPS.[7]

Hybrid solutions, needing both the handset and the network include:

Mobile phone users may also have a selection to permit location information to be sent to non-emergency phone numbers or data networks, so that it can help people who are simply lost or want other location-based services. By default, this selection is usually turned off, to protect privacy.

The 3GPP specified protocol for handset geolocation in GSM networks is called Radio Resource Location Protocol.

VoIP enhanced 911

As Voice over Internet Protocol (VoIP) technology matured, service providers began to interconnect VoIP with the public telephone network and marketed the VoIP service as a cheap replacement phone service. However, E911 regulations and legal penalties have severely hampered the more widespread adoption of VoIP: VoIP is much more flexible than land line phone service and there is no easy way to verify the physical location of a caller on a nomadic VoIP network at any given time (especially in the case of wireless networks), and so many providers offered services which specifically excluded 911 service so as to avoid the severe E-911 non-compliance penalties. VoIP services tried to improvise, such as routing 911 calls to the administrative phone number of the Public Safety Answering Point, adding on software to track phone locations, etc.[citation needed]

The Location Information Server is a service that is provided by an access network provider to provide location information to users of the network. To do this, it uses knowledge of network topology and a range of location determination techniques to locate devices that are attached to the network. The precise methods that are used to determine location are dependent on the type of access network and the information that can be obtained from the device.

Initially, the Federal Communications Commission (FCC) took a hands off approach to VoIP in order to let the service mature and also to facilitate competition in the telephony market.[8] In time, this problem reached the headlines of newspapers as individuals were unable to place emergency calls with their VoIP phones. In March 2005, Texas Attorney General Greg Abbott filed a lawsuit against Vonage for deceptive marketing practices by not making it clear that VoIP users had to actually sign up for E911 service.[9]

When FCC Chair Kevin Martin replaced FCC Chair Michael Powell, he immediately changed FCC’s hand’s off policy and moved to impose 911 obligations on VoIP service providers.[10] In 2005, Chair Martin moved FCC to require "interconnected VoIP services" to begin to provide 911 service and provide notice to their consumers concerning the 911 limitations. The FCC announced that customers must respond to the E911 VoIP warning and those who do not have their service cut off on August 30, 2005. The FCC extended the deadline to September 28, 2005.[11] The E911 hookup may be directly with the Wireline E911 Network, indirectly through a third party such as a competitive local exchange carrier (CLEC), or by any other technical means. The FCC explained that they felt compelled to issue this mandate because of the public safety concerns.[12] Telco industry entrepreneur and blogger Jeff Pulver opined that this was an attempt by FCC Chair Martin to hinder telephony competition to AT&T.[13]

The 911 obligations were imposed only on "interconnected VoIP." The FCC defined "interconnected VoIP" as VoIP over broadband that interconnects with the public switch telephone network.[14] VoIP that is not interconnected, such as two individuals talking to each other over the Internet while playing computer games, does not fall under the obligation.

There are, however, complicated technological problems with implementing E911 with VoIP, which providers are attempting to solve. VoIP phones are on the Internet and nomadic; the geolocation of the individual placing the 911 call can be very difficult to determine. Service providers are attempting to phase in solutions through the I1, I2, and I3 phases. During I1, the 911 call was routed to the 911 administrative telephone lines without location information. During I2, VoIP services would participate in the public telephone networks location database for the location that is identified with that telephone number. During the I3 solution, VoIP service providers would have a true IP interconnection with Public Safety Answering Points and would be able to provide even more valuable information than the legacy 911 system. Where VoIP phones are mobile, geolocation has additional problems; VoIP service providers are seeking access to mobile phone location databases.[15][16][17] These solutions are being developed through the cooperation of the Voice on the Network Coalition and the National Emergency Number Association. Vonage has encouraged its customers to register the locations from which their 911 calls could be dialed with the local public safety answering point.[18] The FCC had continued to add more requirements and mandate a more sophisticated 911 function.[19]

VoIP services have noted an obstacle to full 911 interconnection; in order to interconnect with the Public Safety Answering Point, the VoIP service providers must interconnect with the 911 telephone trunk, which is owned and controlled by their competitors, the traditional fixed-line telephone carriers.[11] This resulted in the New and Emerging Technologies 911 Improvement Act of 2008 which granted interconnection rights to interconnected VoIP services.[20]

There are also other proposed features that are intended to allow telephone callers from large corporate telephone networks, on both traditional and VoIP PBXs, to be located down to the specific office on a particular floor of a building.

VoIP & 911 issues are also relevant to Telecom Relay Services utilized by individuals with disabilities.

911 address

A 911 address contains a uniform number, the street name, direction (if any) and the city. The address number is assigned usually by the grid of the existing community. Each county usually has their own guidelines on how the addressing is done, but for the most part National Emergency Number Association (NENA) guidelines are followed.[citation needed] These guidelines are expressed by the Master Street Address Guide (MSAG). The actual 911 addresses and associated phone numbers are put into the ALI database.

Address signage standards

In addition to upgrading communications systems, many counties and communities in the U.S. have implemented ordinances requiring property owners to standardize the display of house numbers on buildings and along streets and roadways, to allow emergency personnel to more easily locate a given address day or night, even in poor weather. These generally consist of reflective characters, at least 3 to 6 inches high, on a contrasting reflective background. It is necessary for the address number to be affixed to the building or to a separate structure such as a post, wall or fence, provided that such separate structure is located in front of the building and on the building’s side of the street. Compliant signage systems are often advertised as being "E911 compliant".[citation needed]

I had a major decision made these couple of weeks. I am now joining Alcatel Lucent this July 2010.

I will be a SME for ALU for their customer in the North West region. I will be supporting a major customer for its new market.

I will blog more in a few weeks until I arrive in the market.

See you later AT&T……….
