Just a logical question that: the modems are/were 56k and the bandwidth supplied was 64k. As the modem can't go more than 56k where goes the remaining 8k and why is it so? Why 64k is supplied if the modem is 56k...

I hope the question is clear.

I thought the range for a POTS (plain old telephone system) was near the 90-100kb/s range (assuming it's not dsl). The rest is.. just not used.

[AKMafia001]

Do you mean that the rest is unused? If so, why they range is kept different and the modem is 56k. They both can be the same also.

[modi123_1]

It would be a safe bet that yes the rest is not used... there's a question of signal degredation and all that jazz. The rest I didn't quit get - can you rephrase the rest of your questions?

[AKMafia001]

Well! I wanna ask that the modems were 56k right? And the bandwidth providers supplied 64k.

Suppose I have a DSL and my modem might support more but I have a package of 2 mbps so they provide me exactly 2mbps.
Same here, the modems were 56k and the ISP provided 64k bandwidth through it. What for the rest of 8k? Is it used for some specific thing?

Okay there's a disconnect with how the system worked before dsl and cable. Back in the day people paid for a POTS line for calling people, right? You got a modem to hook into that line to dial up a number to your ISP and they were your gateway to the web (since they were hopefully sitting on some fiber or some fast line). You (mostly) paid by the hour to the ISP, not the phone company. There was no guarantee of speed or any nonsense, like it is today, so it's not like the phone company was chinzing you out of some bandwidth - as far as the phone company cared you were making really really long phone call. Your ISP only cared how long you were on surfing. Upgrading your 2600baud modem to a 56k meant you were using your time more effectively since you were able to send/receive at a faster clip.

As it is - being that your average voice call is something like 10kb/s 56k was pushing the infrastructure. Some rural places were having their phone switches overheat from the traffic. Thank god cable came around when it did!

You are 101% correct. I passed those days of dial-up connections.
You know my teacher asked that, if modems were 56k and the ISP supplied 64k so where the rest of 8k goes? What shall I answer him?

Are you sure you gonna redirect me to 1997?

Thanks Buddy!

Hope someone view the topic soon!

The new question is: What is inbound and outbound signaling?

I think you mean in-band and out of band signalling.

[AKMafia001]

Probably, but idk . I guess it might be out of bound.

[modi123_1]

Well it makes a whole world of difference you know..

[AKMafia001]

Would you briefly define them and give me a good link to look?

[modi123_1]

I'm not even sure which words to define. If it's in-band/out-of-band then wiki has two great reads on both for a start...
