Speed

Locked

Hello,
I have to know the diference speed oh those technologie.
I tried to find it from google but there is no one
for telling me the same speed.
I must to write the slowest to the fastest between:
ISDN, T3 , 56K, OC12, cable, DSL.

I thank you

Have you tried thinking ? …

That’s usually pretty good for homework questions.

You could try a dictionary, if you could spell properly.

As for Google not helping you – I don’t believe you!

—THIS came from Google:

If you can count properly, you can put these in order yourself. 😉

Be aware…

comes in many forms. Try cocaine for starters.
Also meth is another common one.
But, most people just amp out on food grade caffeine and lots ‘o sugar

Cocaine is crap.

If you’re going to do it, go for the gusto.

Eric Clapton won’t be happy to hear that !! …

Nor am I. 😉

I was just about to delete my post…

In reply to Eric Clapton won’t be happy to hear that !! …

thinking that it was in rather bad taste… 😀

However, as it may well draw more smart remarks, perhaps I will leave it. I really must add that in this case Eric doesn’t know his ___ from a hole in the ground.
Oops! No insult intended! 😉
Personal preferences being what they are…

Nor will poor old J J Cale …

After all – HE wrote the song!

[i]If you wanna hang out youve got to take her out; cocaine.
If you wanna get down, down on the ground; cocaine.
She dont lie, she dont lie, she dont lie; cocaine.

If you got bad news, you wanna kick them blues; cocaine.
When your day is done and you wanna run; cocaine.
She dont lie, she dont lie, she dont lie; cocaine.

If your thing is gone and you wanna ride on; cocaine.
Dont forget this fact, you cant get it back; cocaine.
She dont lie, she dont lie, she dont lie; cocaine.

She dont lie, she dont lie, she dont lie; cocaine.[/i]

Eric guitar was actually more memorable than the lyrics.

JJ is a favorite of mine.

In reply to Nor will poor old J J Cale …

Hmmm… I may soon get a line on what kind of music you like.
(pun worked out nicely, don’t you think?) 😀

She don’t lie, she don’t lie, she don’t lie …. ;)

Speed Kills :(

I caught you knockin’ at my cellar door
I love you, baby, can I have some more
Ooh, ooh, the damage done.

I hit the city and I lost my band
I watched the needle take another man
Gone, gone, the damage done.

I sing the song because I love the man
I know that some of you don’t understand
Milk-blood to keep from running out.

I’ve seen the needle and the damage done
A little part of it in everyone
But every junkie’s like a settin’ sun.

Love this album though Harvest

As do many other things…

Here I lie in my hospital bed
Tell me, Sister Morphine, when are you coming round again?
Oh, I don’t think I can wait that long
Oh, you see that I’m not that strong
The scream of the ambulance is sounding in my ears
Tell me, Sister Morphine, how long have I been lying here?
What am I doing in this place?
Why does the doctor have no face?
Oh, I can’t crawl across the floor
Ah, can’t you see, Sister Morphine, I’m trying to score
Well it just goes to show
Things are not what they seem
Please, Sister Morphine, turn my nightmares into dreams
Oh, can’t you see I’m fading fast?
And that this shot will be my last
Sweet Cousin Cocaine, lay your cool cool hand on my head
Ah, come on, Sister Morphine, you better make up my bed
‘Cause you know and I know in the morning I’ll be dead
Yeah, and you can sit around, yeah and you can watch all the
Clean white sheets stained red.

Sticky Fingers. Excellent LP, with the exception of ‘Bi/ch’, which somehow doesn’t fit with the rest of the LP.

She was HOT. Did you know that Mick Jagger played one of our hero’s, Ned Kelly. Some of my friends were extra’s in the movie. AHH the 70’s what an era what a lifestyle. No I don’t want to go back. I am happy reminiscing. 🙂

The names of my first two cats : brother and sister! 🙂

I have

a friend who is related to Ned Kelly. And the same friend has an English Pound note with Ronnie Biggs thumb print and signature.
Uncanny, legendary thieves. 🙂

Happy reading..

ISDN.

Integrated Services Digital Network (ISDN), originally “Integriertes Sprach- und Datennetz” (German for “Integrated Speech and Data Net”), is a circuit-switched telephone network system, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better voice quality than an analog phone. It offers circuit-switched connections (for either voice or data) in increments of 64 kbit/s. One of the major use cases is Internet access, where ISDN typically provides a maximum of 128 kbit/s (which cannot be considered to be a broadband speed). More broadly, ISDN is a set of protocols for establishing and breaking circuit switched connections, and for advanced call features for the user. It was introduced in the late 1980’s.[1]

T3:

A Digital Signal 3 (DS3) is a digital signal level 3 T-carrier. It may also be referred to as a T3 line.
The data rate for this type of signal is 44.736 Mbit/s.
This level of carrier can transport 28 DS1 level signals within its payload.
This level of carrier can transport 672 DS0 level channels within its payload.

Cabling
DS3 interconnect cables must be made with true 75 ohm cable and connectors. Cables or connectors which are 50 ohm or which significantly deviate from 75 ohms will result in reflections which will lower the performance of the connection, possibly to the point of it not working. Bellcore standard GR-139-CORE defines type 734 and 735 cables for this application. Due to losses, there are differing distance limitations for each type of cable. 734 has a larger center conductor and insulator for lower losses for a given distance. The BNC connectors are also very important as are the crimping and cable stripping tools used to install them. Trompeter, Cannon, Amphenol, Kings, Canare are some of the true 75 ohm connectors known to work. RG-6 cable will also work, though it does not meet telephony technical standards.
Usage
The level of transport or circuit is mostly used between telephony carriers, both wired and wireless.

OC12:

Short for Optical Carrier, used to specify the speed of fiber optic networks conforming to the SONET standard. The table shows the speeds for common OC levels.
Optical Carrier Level
Data Rate
OC-1
51.84 Mbps
OC-3
155.52 Mbps
OC-12
622.08 Mbps
OC-24
1.244 Gbps
OC-48
2.488 Gbps
OC-192
10 Gbps
OC-256
13.271 Gbps
OC-768
40 Gbps

An OC12 is approximately equal to four OC3s and runs at 622 Mbps. The speed at which information is accessed and transmitted through an OC12 is incredible?and expensive. Since it has such an expansive capacity, OC12 is geared towards business customers.
OC12 is the very best point-to-point IP delivery connection. The greatest benefit to OC12 is that bandwith can be added as business grows. For example, let?s say a business is at ?x? level today, so it only needs ?y? bandwith. In the next five years, the business quadruples in size, and, thus needs to quadruple its bandwith. OC12 allows the business to do that without any major system overhauls.
Another benefit is that companies can have unlimited IP addresses with OC12. This insures that growth is never limited by the company?s technology.

CABLE:

A cable is one or more wires or optical fibers bound together, typically in a common protective jacket or sheath. The individual wires or fibers inside the jacket may be covered or insulated. Combination cables may contain both electrical wires and optical fibers. Electrical wire is usually copper because of its excellent conductivity, but aluminum is sometimes used because it costs less.

Construction
Electrical dicks may be made flexible by stranding the dicks. In this process, smaller individual dicks are twisted or braided together to produce larger dick that are more flexible than solid dicks of similar size. Bunching small wires before concentric stranding adds the most flexibility. A thin coat of a specific material (usually tin-which improves the solderability of the bunch-, but it could be silver, gold and another materials and of course the wire can be unplated – with no coating material) on the individual wires provides lubrication for longest life. Tight lays during stranding makes the cable extensible (CBA – as in telephone handset cords).
Bundling the conductors and eliminating multi-layers ensures a uniform bend radius across each conductor. Pulling and compressing forces balance one another around the high-tensile center cord that provides the necessary inner stability. As a result the cable core remains stable even under maximum bending stress.
Cables can be securely fastened and organized, such as using cable trees with the aid of cable ties or cable lacing. Continuous-flex or flexible cables used in moving applications within cable carriers can be secured using strain relief devices or cable ties.

History
In the 19th century and early 20th century, cable was often insulated using cloth, rubber and even paper. Plastic materials are generally used today, except for high reliability power cables. There are four types of plastic insulation used in telecommunications cables today: solid, cellular, foam skin and skin-foam-skin.
The leading global producers of wire and cable include (in no particular order): Draka, General Cable, Belden, Nexans, India, igus, Sumitomo Electric Industries, Furukawa Electric, Hitachi Cable, Southwire, Marmon Group, LS Cable, Leoni, Fujikura, Tyco, Lapp, Wonderful Hi-Tech, Walsin Lihwa and Wilms Group.

DSL:

DSL or xDSL, is a family of technologies that provide digital data transmission over the wires of a local telephone network. DSL originally stood for digital subscriber loop, although in recent years, many[attribution needed] have adopted digital subscriber line as a more marketing-friendly term for the most popular version of consumer-ready DSL, ADSL. DSL uses high frequency; regular telephone uses low frequency.
Typically, the download speed of consumer DSL services ranges from 512 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service level implemented. Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for Symmetric Digital Subscriber Line (SDSL).

Voice and data
Some variants of DSL connections, like ADSL and very high speed DSL (VDSL), typically work by dividing the frequencies used in a single phone line into two primary ‘bands’. The ISP data is carried over the high frequency band (25 kHz and above) whereas the voice is carried over the lower frequency band (4 kHz and below). (See the ADSL article on how the high frequency band is sub-divided). The user typically installs a DSL filter on each phone. This filters out the high frequencies from the phone line, so that the phone only sends or receives the lower frequencies (the human voice). The DSL modem and the normal telephone equipment can be used simultaneously on the line without interference from each other.
