Can someone settle this bet

[City_Idiot]

ok, my mate and me were fightinhg over the fastest coonect in NZ (for companies aswell) and he seem tothink you can get T1 connections in this country, now i am not sure if T1 is a specfic type of connection or a class of connnection but what is the fast connection a company can get and what sorta of tech is behind it?? I remember on TM there wasa thrred about this and someone said frame relay was the fastest and T1-T3 wasn't around here

P.S

i got $10 riding on T1 not being in this country :P

[whetu]

T1 is in NZ... its just that T1 is an AMERICAN name...we refer to it as something else... i think its equivilent to 2meg cable???

Businesses/education places can basically be their own isp's if they wish (and can afford).. mmmmm SCC Node connection... OC3... mmmm

yuo = teh winnar

[Tiggerz]

well, fastest I have used is a 65meg unit, known as a megastream.. That was nearly 10 years ago. Understand its all gigastream now..

[_N_]

yeah, I saw some ISP advertising it for like 10k$ per month or something like that.

[City_Idiot]

hehe,

Would be good to have a list of all these techs and there speed

*goes to getfoam bat to collect $10*

OC-256

*123
Hello Telecom can you give me a pirce on a oc-256 connection to porirua, wellington?

[NNA2m]

T-1, T-3 and OC-X are all measure of speed as far as I know, so the cable from Oz is probly the fastest you'll get.

[Wibber]

welll you can get t1 and t3 in NZ being 1.54 and 44.7 mbps, t1 is mostly being replaced by SDSL cos its cheaper and has better bandwidth, ATM can go up to 10gbps in theory, but I dont think you can get it that high (the backbone prolly goes at taht speed) and then in some places you can get fibre, some places as part of a 100mbps man (like in welly?) and you can get gigabit fibre put esp for you too, but that will require amputee creation

[NNA2m]

*Starts chainsaw*

[DiscoStu]

America does their own thing (T1 etc) and the rest of the world, well Europe, Aust & NZ goes with E1.

It's a similar ISDN based primary service, but typically:
- E1 is 2.048Mbps (30B + 1D channel)
- T1 is 1.544Mbps (23B + 1D channel)

However, some telecos allow for the user to choose the number of data (B) channels, which obviously effects the bandwidth.

give me an ATM switch anyday.

spot on :) mmmm citilink

[NNA2m]

I seem to remember the cap on Citylink being a gig or so...

Its sort of stupid (for the consumer, not the company :D) that the faster connection you have the lower your cap is...

[Wibber]

are you sure? I'm pertty damn sure NZ uses T-carrier system
*looks at pile of notes*
nah fukit I'll ask someone else who prolly know

mmm stupid tardme(spit, spit, pisssssss) is on City Link, i remember one day the whole thing crashed .. they were offline for over 24 hours, muahaha

[Volodkovich]

Isnt the LANplace server on citylink?

Yeah, and isn't the Japan/US ISDN max. bandwidth 1.544Mb? And the European/Australian ISDN max. bandwidth 2.044Mb?

I'd swear those are the same numbers as the ISDN rates.... :confused: ( Am I missing something? Is T1/E1 just the cable that carries the ISDN connection? )

And BTW, has anyone come across a resource listing the xDSL family? You know, DSL, SDSL, ADSL, HDSL, GHDSL, HSDLS, GHSDSL, VDSL, etc etc etc - d@mnit, I can never keep up with that list.... :(

[Ragnor]

It gets quite confusing between what is a technology, what is a speed rating and what are marketing product/service names...

Strictly speaking the ratings eg: T1, E1 etc relate to the amount of channels (the bandwidth) used..

/Me resist's the urge to start talking about the physical and data link layers... but does so anyway...

The cable itself is usually good ole' copper or fibre, ie: the physical layer....

Generalising ATM, Frame Relay, ISDN are data link technologies and run over physical layer technologies...

Say you have a ATM connection that runs over fibre optic cable.. if it's a 1.54 Mbit connection, you can label it a T1 connection...

Say if it's 2.044 you can label it E1 .. etc etc

[Daza]

some of those speeds on that site are insanely fast *drools*

That site (linked further up the thread) states that you get T3 speeds of 44.736 Mbps over coaxial cable?? I thought that BNC's couldnt get above 10mbs or do they use a differnt type of connector?

ok i found this at the bottom of that site
Cable modem note:The upper limit of 52 Mbps on a cable is to an ISP, not currently to an individual PC. Most of today's PCs are limited to an internal design that can accomodate no more than 10 Mbps (although the PCI bus itself carries data at a faster speed). The 52 Mbps cable channel is subdivided among individual users. Obviously, the faster the channel, the fewer channels an ISP will require and the lower the cost to support an individual user.

but it still doesnt explain much to me, and the good old google just brings me up with web hosting offers and i cant find anything about it in the likes of cisco notes etc etc

[Wibber]

you can run more than 10mbps on coax, but they decied to mostly not, cost is aint cheap

[Geek4Life]

This (http://whatis.techtarget.com/definition/0,289893,sid9_gci213915,00.html) has a good run down the xDSL technologies.

Well after taking 2 undergrad and doing his postgrad paper at the moment I should have that etched in my mind by now :D

LOL, I can't help it, you should see me causing havoc on thier "message boards" all the golden oldies go crazy.

Whats your Trademe user name?

[Wibber]

wow, did you have to use a dredge to find this thread? :p

try to leave old threads be (read: more than a couple months), unless you need to raise a question not asked in the thread or an answer clarified

[Tiggerz]

Well Intel still do a gigastream processor (OC-48) with a 2.8Gb/s line speed scaleable to 80Gb/s with 30 channels.

I believe this is an entry level system.

[krisby]

I never heard the E1 designation used in the UK, as far as I know it was only referred to as T1. When I was at the BBC we had that connection, with several different pipes feeding the BBC, and its different locations. As it was potentially spread across 23000 users, it had be big and we needed several pipes.

The fastest download speed I ever saw though was only about 700kb/s, obviously the internal and external traffic affected the speed, as does the host site, as in general download speeds were only about 50-200kb/s. It was great for downloading all sorts of things, ¦)

At my last place we had an ADSL line feeding our intranet, but as only 4 of us accessed the net it was pretty good, with a 256 connection it was still blindingly quick, but noticeably slower than the BBC. It was especially slow at lunchtimes, evenings and Friday afternoons.

I thought the only place in NZ that had the big T! pipes was wellington and its new commercial network in the cbd.

Having a quick browse through ISPs I can not see anyone who offers a 1Mb line let alone a 2mb line, of course, if you enquired directly they might be able to, but then it becomes a dedicated line I believe, not one that shares access with other users at the exchange.

[Deviant]

Yes but as Wibber points out, I think the bets already been won or lost more than a year ago.

Where's Whetu hiding?

[krisby]

don't worry, I'm talking ****, I just saw paradise have a 2mb line (with only 256kbps upstream though), so I guess they must all offer it.

hmm, i wish.

[Deviant]

Yes but this has nothing to do with the original thread discussion, which was all about commercial high bandwith, not adsl into the home.


Just lay this thread to rest, it's all over rover, zzzzzzzzzzzz.......

well you were wrong, and citylink is hardly new (going on 8+ years now)

Are you implying that I bring a handful of lockdown justice? Meh.. the discussion so far is at least constructive/informative... if things get spammy here then obviously myself or another mod will step in as per norm...

BTW I'm "hiding" at work, and by "hiding" I mean "contemplating the many ways in which I find the prospect of death preferable to this horrible horrible job yet I'm going to reapply for this job after my contract is terminated tomorrow because it's money and money pays bills" :rolleyes:
