Speed 8 is single-digits 2-9 here also. My emphasis point was rather on the no. of digits allowed and inability to combine with 10xxx prefixes and international numbers. Since the topic came up again, I get to add the history. I originally bought speed-30. This allows 2-digit dialing with digits 20-29,30-39,40-49. I only used a few so I wanted to convert to speed-8 using 1 digit 2-9. This was years ago and just about nobody knew how to deal with custom-calling feature customers in the first place, let alone subtle changes. For the first several months, I got no change and each time I called they would flounder around and say they would fix it. (611 repair service was a universe away from understanding anything about new ESS features). I was quite possibly the first person in the world to want to convert from speed-30 to speed-8. Anyway, upon continued testing I discovered that someone had provided a perfectly logical transition path, but nobody knew it existed. Purely empirically I discovered that I could store NEW single-digit codes for 5,6,7,8,9, while still using all 30 previous 2-digit codes in decades 20-29,30-39,40-49. For a transition time I had speed-35! Moreover it allowed both 1- and 2-digit codes, most lovably convenient. But if I tried to change a code in the range 20-49, I could only store 1-digit codes for 2,3,4. Each wiped out the corresponding decade of older 2-digit numbers. Too bad this actual capability is not available as a steady state. If it still works, somebody could get speed-35 by this path, loading their unfavorite 30 in the range 20-49, converting, then loading 5-9 with 5 more single-digit codes. You want to reprogram? Cancel and repeat the above sequence. Costs a little extra for the feature-change fees, but could be worth it. Thanks, Doug Speed-calling 8 correction and history [correction. If you had used "2,3,4" from your 8 number speed calling you would have probably found that it worked (at least it does here). Speed calling 38 is a common practice here, and we use the # key to indicate termination of code (differentiating between 2 and 20). --jsol]
