ISP Information:
An application written specifically for a particular vertical market, as opposed to more generic multi-purpose applications such as office suites. One example is a program written for the insurance industry that computes insurance rates. Such an application is useless in any market besides the insurance industry.

Vertical Market Application - Mike McDonald wrote:We just switched our company lines from SBC to Mpower (which was shortlythereafter acquired by LDMI, another telco here in MI) a few months ago.Our dialup connection was a USR 28.8 modem with firmware upgrade to 33.6a long time ago, no problems. With SBC, for *YEARS*, the little modemonline icon always said "28,800" which we assumed was the top speedlimited by the old modem, consistently. Beginning the day we switchedto mpower/LDMI, our icon indicated speed dropped to a range from 21,400to 26,400, and if we redialed enough, we could usually get it up to26,400.Since complaining to mpower/LDMI, several service ppl have checked theline, and we've had a "vendor" meeting with SBC, etc etc: all theservice ppl tell us that the line is working perfectly, contrary to ourThey are indeed telling you the truth. Your line is workingperfectly, and what you have described proves it!Perfect is defined as meeting the minimum specifications. Andif a line just barely meets those minimums, you will probablyget either a 14.4kbps or maybe a 16.8kbps connection. If youget a higher speed than that, your line is clearly *better* thanthe definition of "perfect".Of course, some lines are more better than others... ;-)What you have sounds like is a fairly common problem. If a"remote unit" (and there are dozens of names for these things,but they all amount to the same thing) is situated some distancefrom the telco Central Office in an effort to reduce cable pairrequirements and extend service a greater distance (with noconcentration at all, 24 channels are provided using only 2cable pairs rather than the 24 that would otherwise benecessary, plus with T1 repeaters the distance can be half wayto the next county), there are two ways to interface those linesat the telco Central Office.One way is an all digital interface (which you don't appear tohave) and works just fine for v.34 and v.90 connections.The other way, which is used when a switch already has enoughline capacity, converts each digitized line back to analog andinterfaces with the switch as if it were a totally analog line.This method has the effect of making v.90 connectionsimpossible, and reducing v.34 connections to usually either24kbps or 26.4kbps, with an occasional 28.8kbps.In other words, unless the telco just happens to have some linesconfigured to be fully digital, you are out of luck. If youfind anyone there who can understand what you are talking about,the digital interface is sometimes called a "trunk side"interface or an "integrated" interface. The analog method,which you do not want to keep, is called a "line side" or a"universal" interface.Just be careful that you do not overly annoy them, because asI have explained above, your line *is* working perfectly. Youare getting what you are paying for, and they do not sellPlain Old Telephone Service (POTS) with specs that your linedoes not meet.salesman telling us initially that they could fix this.Good salesman, eh? His job is to sell you, and he did.My only other experience with dialup is with my home computer, whichalways connects between 45k-50k!!!So now we've plugged the same office telco line into a newer, faster p3box with a 56k v.90 modem and guess what? ITS DOWN TO 24,000,consistently! So apparently it's not the modem or other CPE.This may not sound like a big deal to broadband users, but when youralready slow connection gets even slower, and your salesman didn't tellyou about it up front, it's a little problem that just got bigger.We're too far for dsl at any reasonable speed/price ratio.Any advice on improving this would be appreciated.Thanks--Floyd L.
