WOW

I thought I was doing well, having just upgraded to 1Meg Broadband, here in the UK. What a long way I have to go.

Mind you when I connect for work, AND I work for a MAJOR telcomms company we use 56K dial-ups, but I only get 33K out of it. Plus when I use my lap top I have to use GSM which is a blistering 9600.

Oh well should be there by 22nd centry.

My first modem for my IBM PCjr was 300 baud or bps. I used that for over a year until a local BBS sysop took pity on me and gave me his old 2400 bps modem. Then I was really flying!

Before I retired, I worked at AT&T 1998-2000, than MCI 2000-2003. I heard that quite a few people had T-1 internet service and and heard of one private T-3 internet line. Mostly computer game developers, but also some afluent on-line game players...

Private internet OC (Optical Cable) connections will be hard to get, unless you move to an office district where the OC is already under the street!

Let's get realistic.. most people are going to be operating on dial-up or broadband.. few have DS-3 lines or above. This is from a USA perspective.

OC-768 40Gbps <-- does exist, Internet2 provided by Qwest
OC-255 13.21 Gbps <--doesn't exist in practice
OC-192 10 Gbps <--most carriers use this as a national backbone
OC-96 4.976 Gbps <--not used
OC-48, STS-48 2.488 Gbps <-- commonly used for redundancy on national backbones, aggregation points
OC-36 1.866 Gbps <-- doesn't exist in practice
OC-24 1.244 Gbps OC-18 933.12 Mbps <-- doesn't exist in practice
OC-12, STS-12 622.08 Mbps <-- aggregation points
OC-9 466.56 Mbps <--doesn't exist in practice
OC-3, STS-3 155.52 Mbps <-- very common with large enterprises
OC-1, STS-1 51.84 Mbps <--European standard STS1
T-3, DS-3 North America 44.736 Mbps <--very common for businesses
E-3 Europe 34.368 Mbps <-- very common for businesses
Category 4 cable 20 Mbps -- who would use this?
Token Ring LANs 16 Mbps -- and this is WAY legacy
Thin Ethernet, category 3 cable, cable modem 10Mbps <-- i sincerely hope you aren't using this
E-2 Europe 8.448 Mbps <--E-2? why would anyone want an E-2
T-2, DS-2 North America 6.312 Mbps <-- doesn't exist in practice
Standard ADSL downstream 6.144 Mbps <-- varies by carrier The "A" is for Asymmetric... what about IDSL, SDSL, VDSL
DS-1c 3.152 Mbps <--doesn't exist in practice
E-1, DS-1 Europe 2.048 Mbps <--very very commong
ADSL, T-1, DS-1 North America 1.544 Mbps <-- you forgot to mention HDSL
ISDN 128 Kbps <--in reality, it is 144Kbps if using signaling channel for data
DS-0, pulse code modulation 64 Kbps / or 56Kbps if using the 8Kbps for signaling


everything else is too slow to mention
