This work has been merged into a media gateway control protocol (MGCP) effort--a specification currently available to carriers, service providers, and hardware and software manufacturers. A draft of the standard has also been sent to a mailing list within the IETF and floated to a European standards body. Level 3 previously had organized an advisory council, made of a wide variety of network-oriented companies such as Cisco, Ascend Communications, Ericsson, and Alcatel to supervise its standards efforts.
A consortium of companies gear ua protect stash case for apple iphone 7 plus and 8 plus - graphite/black up for the opportunity to delivering voice calls using Net technology by joining efforts to create standards, Parallel efforts to create a standard for voice-over-IP, or Internet Protocol, championed by Level 3 Communications and Bellcore, have been merged in order to gain greater consensus, The move comes as initiatives for the embryonic IP voice technology inch closer to formal standards bodies, such as the Internet Engineering Task Force, The respective standards provided technology bridges that allow typical circuit-based phone networks to communicate with an emerging set of "green field" networks and layout upgrades based on IP, the transmissions protocol of the Net..

The Tempel-Tuttle comet, which crosses paths with Earth once every 33 years, last passed the planet in February leaving a fresh trail of ice and dust particles in its wake. The comet's tail, about 200,000 kilometers wide and 16 million kilometers long, creates the ensuing Leonid meteor showers. Every November, the Earth passes through Leonid. But the debris is expectedto be particularly heavy this year, due to the Tempel-Tuttle comet's recentpass, which pulled millions of meteors across the sky. Thebarrage--expected to peak at 150,000 meteors per hour during a three tofour hour window from about 2 p.m. to 5 p.m. PST tomorrow--poses a seriousthreat of damage to hundreds of orbiting satellites.
"We've all got our fingers crossed," said Mark McKibben, president of theSouthern California chapter of the Society ofSatellite Professionals International, an industry trade association, "The odds go up that there will be a strike on a satellite and it could lead to a catastrophic failure," McKibben said, A Cosmic BeatingThe average life span of a satellite is only 12 to ua protect stash case for apple iphone 7 plus and 8 plus - graphite/black 15 years, since they are constantly bombarded by loose matter while in space, "They just take such a beating up there," said John McCarthy, a spokesmanfor Loral Skynet, a subsidiary ofLoral Space & Communications..
Satellites suffering damage from meteors is nothing new. The effectiveness of most satellites, in fact, is reduced over time by cosmic dust. But the Leonid meteor showers are expected to be especially heavy over the next three years. Experts explain that even a grain of sand--hurtling at hundreds of thousands of miles per hour--could do significant damage to a satellite. Some experts said the particles are expected to travel at 200 times the speed of sound--and can hit with the force of a .22-caliber bullet.
