Why do modems only download 53 ksomething or other and - samintx - 08-20-2006
they are built for 56? I know it is the law but WHY? that doesn't make sense.
Also, I have a modem coming but will any modem (external) work on my MacBook Pro? Got info transfered and was all ready to post from it and....hey, mom. No Modem!
Does that baby get hot on the bottom.

My understanding is that the FCC imposed the regulation of limiting signal voltage to reduce interference between adjacent wire pairs.
My modem has recently reported speeds of 54.6k, so I would be inclined to believe the rumor that the regulations have been relaxed a bit.

perhaps there is an express slot solution? The one time I used a usb modem with my old g4 yikes, it was pretty flakey. maybe the've improved.

56K modems rely on digital phone lines. These lines use 8-bits for each audio sample, and they sample at 8000 times a second. This gives a maximum of 64 kbits of data per second. One bit in 8 is used as a command bit, so the real life limit is 56k.

That is what limits the theoretical max to 56K on the digital portion of the connection from the ISP to your local office. The FCC limits on signal strength to keep the analog modem signal from interfering with adjacent pairs applies to the analog run from the office to your home. That limits the modem in practice to less than 56K. Most often you will see the speed closest to 53K as your max, but if you are on a short, clean run to the central switch then you might see 54k like Filliam.

Let me get this straight ... you bought a MacBook Pro and never checked to see if it has a telephone modem??
Wait, wait ... you're still on DIALUP?!
Just kiddin'. You mentioned you live in a small town, so it's unlikely that high-speed is yet a viable option for you. Since that's the case, I *highly* recommend the Apple USB modem for $49. You might find something that is cheaper, but it will be QUITE the little miracle to get it to perform as seamlessly as Apple's own modem (clue: modem manufacturers NEVER bother to test to see if their products work with Macs).

chas_m and all the ships at sea....I ordered the Apple modem with my MacPro but it is on BO. I think is has just shipped, however.....
Guffaw all you like, smarty pants....I knew the computer didn't have a modem built in and thought it was silly not to have a modem in the computer.....nahneenahneenahnah.....so there!>
<I just baked some oatmeal, carrot and corn flake cookies...see if you get any! ;-)
3 different batches of cookies not oatmeal, carrot and cornflakes all in one cookie!

I can assure you that if your modem software is reporting 53K, it's lying.
