VoIP technology enterprise LAN network approach to explore

1 Introduction

The use of VoIP technology, through technical integration, traditional enterprises with traditional PSTN voice LAN data services combined to enable them to achieve in a network of low-cost IP voice and IP data services, which enhance the enterprise LAN network of non-IP call processing capacity, to expand its use of function, reduce the external costs of doing business (a large number of long-distance telephone, fax, video conferencing, voice, multimedia network information services, etc.) have a very important practical significance.

Traditional enterprise LAN itself does not have to non-IP voice switching functionality, PBX systems are not equipped with the same IP data exchange, allowing PBX and LAN network system between the two independent of each other, can not directly mutual visits, network bandwidth and speed can not be further The fully tapped and utilized, limiting most new enterprises, a large number of multi-media business information needs. Under such circumstances, the proposed VoIP technology applications in the enterprise network environment under the conditions of the issue of technology integration. However, with the commercial network of VoIP technology is different, enterprise LAN network by a dedicated and strong, the expansion of poor performance, which constitute the situation more complicated, there will be an enterprise Intranet in accordance with different circumstances, to consider the feasibility of the implementation of VoIP technology.

2 traditional enterprise networks and the application of VoIP technology

In most cities, then the existing telecommunications PSTN City Council, the PBX switching system with enterprises as the equivalent of city council if a client access to the city Board PSTN systems, PBX switching system so that enterprises occupy PSTN telephone relay system, an independent Board to and a number of relay number of resources to the enterprise by a certain percentage of traffic assigned to concentrate市话网connected with the trunk. This is in fact based on a traditional physical port or circuit-switched form of a fixed connection, it must make every PBX extension users with a physical switch ports associated with the user changes location, the user cables physical configuration must also change accordingly, which makes network scalability and flexibility of system configuration by a lot of restrictions, thus enterprise VoIP network hopes that with the integration of technology to solve this problem.

VoIP in the enterprise-class system, the connection between the terminal equipment is mainly based on the logical network structure, based on the circuit can be connected to physical port corresponds to the number of logical ports, the number of logical ports by Sekimori definition, equipment IP address according to the logic of information identification, through the form of packet switching, not only from the PBX can also be the first to voice TSI isolate voice signals and call control signals to the LAN data network to achieve the figure of the voice signal conversion and transmission at the same time, You can also call the server's IP address of the equipment to manage (add, delete and modify), so users in the network expansion or change, no need to switch physical port configuration, only the logic of some or individual ports to redefine or IP addresses can be modified. For example, users can insert the phone any available network port, the network of the Telephone IP address to identify users, rather than need to know the specific location of the phone. Therefore, based on the definition of logical network structure and connectivity, as a LAN network traffic through the redistribution of a new approach, in the IP PBX equipment can be completed at the same time the exchange of data and voice, to realize in a LAN network to establish low-cost, voice value-added business services.

Commercial networks and VoIP is different: the enterprise network, in considering the VoIP technology, it is necessary to consider the different needs of voice and data transmission requirements of real-time using VoIP technology to determine suitability; the network using the existing structure to determine which types of VoIP access forms, IP transmission network design how much traffic (involving network congestion and packet loss and other priority issues); a full understanding of the tender of the program suitable for a variety of VoIP gateway equipment (independent network Guan, routers, gateways, remote access servers (RAS) gateways, IP PBX Gateway) and agreement (H.323/H.245 or SIP) compatibility and other issues; according to network calls the largest possible number of and equipment of the information processing ability to forecast the demand for network bandwidth, determine the appropriate port number; specific understanding of each of the IP packet gateway devices encoding, compression methods and prioritize the way (the impact of delay of three factors), and to consider whether there is a need as Sekimori Gateway management software such issues, so as to maximize the realization of the system to develop the design features and equipment to minimize the cost of the investment. To this end, according to the enterprise network with different situations constitute a form from the network could be attributed to the following several easy to integrate enterprise-class solutions.

A new generation of flash memory card can store 2TB capacity of 100 high-definition movies

the SD Association was informed that today will be in the 2009 International CES Consumer Electronics Show announced a new generation of SDXC (eXtended Capacity) memory card standard. To adopt the standard SD card capacity will reach 2TB (1TB = 1024GB), read and write speeds of up to second 104MB, the future development of routes to reach second 300MB.

According to presentations, SDXC standards developed by the SD Association, a substantial increase in the speed of the memory card interface, while retaining the SD interface. An open standard specification and will be released in the first quarter in 2009. SDHC, Embedded SD specifications, SDIO specifications, will also benefit from the speed of the new SD interface.

Market research agencies NAND flash memory semiconductor company Gartner Research Director Joseph Unsworth said: "SDXC combination of higher capacity and faster transmission speed, the use of NAND flash memory technology, a big storage capacity and interactive portable memory card with high ideals choice. in the industry support, SDXC so manufacturers have the opportunity to promote consumer demand for electronic equipment to upgrade its mobile phone features and functions to more advanced and beyond the ubiquitous SD interface. "

Allegedly, SDXC allows mobile phone users to enjoy the benefits, especially in the field of 3G in China has just started. Greater capacity, faster transfer speeds and thus have more entertainment and data storage space. 2TB SDXC a memory card can store 100 HD movies, 60 hours of HD recording, or 17,000 photos fine.

SD Association Chairman James Taylor said: "With SDXC, consumers may be higher-quality content quickly downloaded to mobile phones, such as games, video, music and so on, consumers can have a rich media experience and content. SD interface has in the mobile phone proved its worth as high as now, SDXC memory card capacity will further enhance the precision of mobile phones and increased consumer demand for content. "

It is understood, SDXC specifications using Microsoft's exFAT file system, in a wide range of computer, consumer electronics equipment, mobile phones, with large capacity and high interactivity. exFAT system is designed specifically to improve compatibility with the flash media, for instance, data portability, in removable media with a number of platforms and devices such as interactive.

Recession hits Josh Brolin glass industry of Firozabad

Almost 60 per cent of the glass factories have closed down their shutters.

'The period of recession has more than 80 per cent of its effect on the Firozabad's glass business. We are not left with even 20 per cent of the business because Firozabad's glass business depends on export. At this moment in countries like Europe and America, recession has hit the companies, markets, stores and banks very heavily, ' said Mukesh Pal Bansal, Chairman, Firozabad Glass Export Association.

'All the orders that we used to get from them they are getting cancelled. The buyers who placed orders are finding excuses to cancel their orders and we are no longer receiving any new orders, ' Mukesh added.

The balance of presenters and winners included Marcia Gay Harden toasting “Frozen River” director Courtney Hunt for Best First Film; Sigourney Weaver giving Best Animated Film to “Wall E” director Andrew Stanton; “Nightline” host Martin Bashir — with a broken wrist — bestowing Best Cinematography on “Slumdog Millionaire” director of photography Anthony Dod Mantle; “Angela’s Ashes” author Frank McCourt saluting Best Actress Sally Hawkins (still recovering from a broken collar bone) from “Happy Go Lucky,” and Salman Rushdie doing the same for that film’s director, the marvelous Mike Leigh.
Jamie Foxx’s House; Times Discovers Donors

According to Mukesh, the main reason behind the industry getting affected is the huge stocks rendered useless by the orders being cancelled in the eleventh hour.

While the industry seems to be on the verge of shut down, more labourers remain unemployed. Till now more than 75 per cent of them are unemployed.

'Situation of the labourers has turned worse. They are neither getting food to eat nor are able to raise their children properly. Everyday, we cover a distance of 16 to 17 kilometers from our village to the factory. But when we reach, we sometimes get to know that we won't be working that day as there is no work to do and we are asked to return back to our villages. This has been happening for the past six months, ' said Bhola, a labourer.

Firozabad at present is known worldwide due to its glass industry. Since 1989, it started production of artistic glassware in different colours and shades.

About four hundred glass industries are registered in Firozabad making different types of glass product. They are using natural gas instead of coal.

The 50 per cent productions of these units are exported to different countries. But the recession in the world markets has hit the industry hard in 2008.

ONGC regains position green motor

Oil and Natural Gas Corporation (ONGC) today regained its position as the most valued state-run entity in the country, a week after it was toppled by power generator NTPC.
A Phoenix company is developing a piston engine that runs without burning any fuel or creating exhaust. It may represent a breakthrough in producing electrical power more efficiently—and cleanly. Even the pressure in natural gas lines could drive this motor, without using any of the gas.

The engine also can be powered with liquid heated by the sun or by the energy that other machines waste, according to Rick Davis, who is on the board of directors for a company called PowerVerde. Partners Fred Barker, a retired Boeing engineer, and George Konrad, an expert machinist, developed the first prototypes of this engine.

Their motor uses a propulsion system they describe as a miniature version of something called an organic rankine cycle (ORC) generally used in much larger applications. In basic terms, the ORC uses a fluid that expands quickly when heated. The expansion pressure drives the engine. Then the fluid is cooled and returns to begin the cycle again.
Davis, Barker & Konrad explain their motor
At the end of the trade today, the market cap of ONGC stood at Rs 1,54,800.90 crore - ahead of NTPC's Rs 1,49,284.13 crore.

Shares of ONGC today surged 6.43 per cent to Rs 723.75, while NTPC dipped 1.60 per cent to Rs 181.05 at the end of trade today.

ONGC and NTPC are followed by MMTC, SBI, NMDC, BHEL, Indian Oil, SAIL, Power Grid and GAIL India in the top 10 most valued PSU firms.
The fluid that powers the engine could be heated by relatively small solar panels or excess heat from other machines like diesel generators. Davis says their motor could use the wasted heat from a diesel generator to produce another 50 percent of the electricity the diesel generator is putting out.

But the first electricity pumped into the grid by a PowerVerde engine probably will be produced using the pressure in natural gas pipelines. Davis says, when a gas line branches off from the main pipe to serve a group of homes, a set of valves called a “city gate” reduce the gas pressure to safe levels for distribution.
Of this, six companies - ONGC, NTPC, MMTC, SBI, BHEL and NMDC - figure among the 10 most valued firms across public and private sector entities.

Of the 10 most valued firms in the country, ONGC is ranked as the second most valued firm after private sector behemoth Mukesh Ambani-led Reliance Industries.

The U.S. Centers for Disease Control and Prevention warned that the use of alternative sources of fuel or electricity for heating and cooking can cause carbon monoxide to build up in confined spaces, such as a home, garage or camper, and can poison people and animals in enclosed or partially enclosed areas.

Carbon monoxide is found in combustion fumes, such as those produced from small gasoline engines, stoves, generators, lanterns, gas ranges, gas dryers and hot water heaters; or by burning charcoal and wood. Each year, more than 500 people nationwide die as a result of CO2 poisoning, according to the CDC.

Common symptoms include headache, dizziness, weakness, nausea, vomiting, getting red in the face, chest pains and confusion.

“The symptoms mimic many other illnesses,” Elliott said. “People just don’t pick up on it.”

'Doubt' leaves Ceiling Lamp

The streetcar bell, a gift in 1997 from then-San Francisco Mayor Willie L. Brown, went into a cardboard box labeled "decor, pictures, plaques."

A white dove kite, designed by a Virginia Beach woman for the 1996 Summer Olympics, was snipped from the ceiling and packed away.

A drawing of dragons frolicking outside a house by a third-grader at Creeds Elementary named Kasey, was wrapped up with paintings from other children throughout the years.

Meryl Streep portrays the nun with such ardent conviction and swift sarcasm that it really is believable when, after Flynn promises to fight her accusations, Sister Aloysius tosses out, "You will lose." Although it's a departure in theme, Streep's vociferous role is comparable to that of Miranda in "The Devil Wears Prada" (2006), except now the nun wears black.

Although Streep's character is well-cloistered and devout, a certain spark lurks behind her sacred surface. She hangs a framed portrait of the Pope on the blackboard, not to remind her students of his papal holiness but to use the frame's glass to catch school-age wrong-doers in action. In one hand she wields a Bible and rosary and in the other a carefully crafted verbal slingshot loaded with snide witticisms and acerbic remarks.
The once-married nun is hardly obedient, as Flynn is so kind to remind her. Sister Aloysius rails against the priest's authority with incessant interrogation and promises to have him removed from the parish, even if it means her own excommunication.

Photos of Mayor Meyera Oberndorf - in a floral sundress and straw hat, surrounded by businessmen at her first ribbon-cutting in 1988 and of her greeting President Bill Clinton at a White House dinner - were stuffed away.
In the end, it took nearly 100 boxes to hold the mementos of Oberndorf's 20-year career as Virginia Beach's first elected and longest-serving mayor. That doesn't count the plaques and paintings that were considered city property and not the mayor's.

It is almost as if she undergoes a transformation throughout the film. At first a stalwart authority figure, she later passionately pursues justice with an almost reckless abandon. The exchange between herself and Father Flynn almost immediately escalates into a rampant power struggle between the two ecclesiastics that almost begs examination of their motives. Now, what was it they were arguing about?
Philip Seymour Hoffman plays very opposite Streep's character as the alleged pedophile priest, Father Flynn. He advocates a "friendly" relationship with the school's children and believes the clergy members should seem more like family members to the Bronx parish. The Santa Claus-esque Flynn is all for the radio music Aloysius abhors and thinks "Frosty the Snowman" should be sung in the school's Christmas pageant.

According to a Dec. 10 broadcast of "Fresh Air" on NPR, Hoffman was the only "Doubt" cast member to know the intended resolution of John Patrick Shanley's Pulitzer Prize-winning drama from which the conclusion-less film version is adapted. Because of this he dominates the role with a perfect blend of resolute conviction and nervous rage. Flynn sticks to his story and emanates innocence for those who believe him guiltless, but later he lashes out at Aloysius and makes rash decisions in, to those who condemn him, what seems like a panic to save face.
Shanley, who directed the movie adaptation, plays it safe with minimal characters. Few roles other than those of Streep and Hoffman are highlighted or even existent. Amy Adams's depiction of Sister James is at times amusing and at times heartbreaking, and Joseph Foster captures the timid mannerisms of the downtrodden Donald Miller. But one supporting role is particularly memorable. Viola Davis successfully illustrates Donald's woeful, almost apathetic mother within the span of just one scene. Mrs. Miller's dramatic interlude is necessary to a plot that would otherwise have become stagnant, laced only with banter between the nun and priest.

"Doubt" deserves acclaim for its detailed representation of the 1964 Catholic Church, in everything from the ceremonial proceedings of Mass to the school rules to the clergy's attire.

Shanley also makes use of symbolism and setting. One minute we're inside the church's bright, ethereal nave, and the next we're out there where torrential downpours ensue and autumnal gusts gather the season's fallen leaves in windy whirlpools. In its avant-garde melodrama, "Doubt" kind of resembles "Chocolate" (2000), which centered somewhat on religion as well.
The city paid movers $862 to clear Oberndorf's belongings out of the mayor's office in City Hall on Tuesday. Will Sessoms, who defeated Oberndorf in the November election, will be sworn in on Monday.

Nextar cuts the cord with etcetera seems surprisingly useful

While we feel that some objects shouldn't be solar powered for the sake of being solar powered, we can't help but dig Nextar's approach here. The NXBT-001 / NXBT-002 seem to primarily differ only in the amount of charge they can hold, with the former offering 250 hours of standby time / 10 hours of talk time and the latter boasting 150 hours of standby time and 6 hours of yappin'. As for functionality, both devices are designed to enable handsfree calling in the car with any Bluetooth-enabled mobile, and of course, they each soak up the sun while you're out cruising about. The best part? The fact that you no longer have to run yet another power cable to that 8-port cigarette adapter hub sitting in your center console. The pair will ship this Spring for $59.99 / $69.99 (thanks to a bundled caller ID display), respectively. Full release is after the break.
Two Advanced Technologies Provide Smart – and Green – Solution to Cell Phone Driving Usage; Items to Be Featured at 2009 CES along with Other Advanced Nextar Products
Chinavasion's latest piece of steaming trash is actually very un-trash-like, as it thoughtfully meshes a number of in-car technologies into one single cigarette adapter doodad. The Plug-In Car MP4 Player with LCD Display manages to bundle an MP4 / MP3 player, 1.5-inch LCD and 4GB of memory into a device that plugs neatly into your car's cigarette adapter, and the inclusion of an FM transmitter means that you won't even need to bring your own DAP to get tunes flowing in the car. Moreover, the SD card slot enables even more jams to be loaded on if you're embarking on a serious road trip, and the USB socket makes PC-to-whatchamacallit transfers a cinch. We're truly impressed with just how awe-inspiring this thing is for €21.57 ($29); too bad we don't trust the quality one bit.
La Verne, CA – December 30, 2008 – Nextar?, a designer and marketer of bold and new consumer electronic products with mass appeal, is combining Bluetooth? technology and the power of the sun in providing a solution for hands-free cell phone usage while driving: solar Bluetooth car kits (models NXBT-001 and NXBT-002). Bluetooth 2.0 technology provides up to 30-feet of hands-free capability. The 'green' solar chargers recharge while a vehicle is driven, eliminating the need to have a charger plugged in during use. Nextar will feature the units at the upcoming 2009 CES in booth South 3 31753.
"Many states have passed laws prohibiting cell phone usage while driving, unless it is through a hands-free device," commented Eddy Zheng, Nextar founder. "By combining two advanced technologies, Nextar makes it possible for drivers to keep their hands on the steering wheel while using their cell phones. Our Bluetooth car kits also have the added advantage of being solar powered, making them 'green' friendly."
With slim, fashionable designing, the units are engineered with Bluetooth v2.0 class 2 technology and have an effective radius of approximately 30 feet. They feature auto Bluetooth connection, pick up/off calling, last calling, voice calling, DSP for echo canceling and noise reduction, full duplex, and mute functions.
NXBT-001 offers 250 hours of standby time and 10 hours talk time when fully charged. It includes a LED signal display, supports profiles A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Video Remote Control Profile). These two profiles, respectively, define how audio can be streamed from one device to another and allows for a single remote control to control a series of A/V equipment.
NXBT-002 offers 150 hours of standby time and 6 hours talk time when fully charged. Additionally, it features caller name and ID display on a super-bright LCM screen.
Accessories for both models include a car adapter and bracket.
