T1 is a phone technology - digital transmission line running 1.5M/sec up and down. Normally divided into 24 channels for voice, so a business commonly orders a T1 line to their PBX to provide 24 phone lines. You can also purchase "fractional T1" (some number of channels), and you can also use the line for Internet access. It has been a primary revenue source for phone companies for 20 years or so.
So, specifically to your question, it _may_ be for Internet or voice, but from the phone companies perspective they don't care. I believe the term "high speed internet" is used generically for anything over dial up, so this term includes T1, DSL, cable, fiber, etc. Some comment earlier compared US broadband penetration to other countries. The phone companies have been discouraging DSL for years because it's killing their T1 business. DSL for business can run at 1.5 M/sec up to 6 M/sec over regular wires for a fraction of the cost (DSL can be faster than T3, which is digital at 4.5 M/sec). Of course, thanks to cable competition the DSL dam has broken and Verizon and others have jumped on board. While I haven't been following the whole thread of this conversation, it is sounding to me like its bandwidth restriction which is best solved by monitoring the network to determine what's competing for the traffic. Sometimes this congestion is a service running out there flooding your network that isn't needed. You can tune your network, or use a router that allows prioritization of packets so that the important traffic goes in front of other traffic. Also, packet latency (in my experience) can be an issue deep inside your ISP and not necessarily related to the technology between you and them. My 200k/sec DSL line was getting sub 20ms round trips and others' cable modems (at 3M/sec) were getting 150. There's much more to network traffic than the connection between you and the local switching station. Hope that helps. -Lyle PS: Ironically perhaps, T1 as normally implemented today is a T1 connection from you to the local switch office where it goes into the phone companies "cloud" as IP based VPN. Most of the long haul traffic is now IP based on fiber or frame relay, and they use VPN to create a virtual circuit. The days of the term "leased line" being a physical connection between two points is long passed in most markets. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Toppenberg Sent: Friday, May 13, 2005 5:11 PM To: hardhats-members@lists.sourceforge.net Subject: RE: [Hardhats-members] Re: Hardhats-members digest, Vol 1 #1015 - 6 msgs Tell me, this point to point T1 is different from a high speed INTERNET connection then? I had been thinking that the internet was still involved. We would also need an internet connection then I suppose.
