So an SME will probably be using the same eqpt as BT whereas a larger ones may have their own eqpt. BT would not ( in theory) be able to provide an inferior service to the SME's under competition laws. I say in theory - my local ISP is ITSOS and we had a lot of line problems. We got to the call out stage - where BT would have turned up at my house and checked the line from here [theres nothing wrong thats £70 thankyou] when the line suddenly went stable and has not crashed since ( 2 mths). I think the line was fixed on the Friday before the Monday call out and they forgot to unfix it when we cancelled the callout. But I could just be paranoid as I worked for BT. > > When it comes to load, some providers skimp on the amount of equipment > required, hoping that most of the time, not many of their customers are > on-line at any given time, and those that are, are just downloading > email. as a result, you can be in a situation whereby you've got a 7MB > connection, but due to contention (fighting for bandwidth with other > customers) issues, you only get what amounts to a 500k connection. > Better (read; more expensive) suppliers have far greater capacity to > cope with the demand their customers may make. I've always found that if there is contention everyone get squeezed no matter who you are with. Though nowadays that seems to be more down to the source host than the network - ie its the site your downloading from thats putting on the squeeze and not the ISP. No point in an 8M line trying to download from a site that wont deliver more that 128k down a single connection.... A lot of people think their connection is being squeezed when its the site their downloading from.
