  RFC 4040 (rfc4040) - RTP Payload Format for a 64 kbit/s Transparent Call
For such applications, there is a necessity for a transparent relay of 64 kbit/s data streams in real-time transport protocol (RTP) [4] packets.
This mode is often referred to as "clear-channel data" or "64 kbit/s unrestricted".
The primary function of this payload format is to add a transparent transport for a 64 kbit/s data stream.

4 kbit/s – minimum necessary for recognizable speech (using special-purpose speech codecs)
32 kbit/s – videophone quality (minimum necessary for a recognizable talking head)
Note that because of advancing technology, the actual bitrates used by some of the compared-to devices is significantly higher.

56 kbit/s (56 kilobits per second) is the (A collection of facts from which conclusions may be drawn) data rate of a normal single channel digital telephone line in (A continent (the third largest) in the western hemisphere connected to South America by the Isthmus of Panama) North America.
Note: due to FCC power limits, the limit over public telephone lines is 53.3 kbit/s.
Due to noise, the actual speed may be lower.

 RFC 2422 (rfc2422) - Toll Quality Voice - 32 kbit/s ADPCM MIME Sub-type Re
ITU-T Definition Recommendation G.726 [G726] defines the characteristics that are recommended for the conversion of a 64 kbit/s A-law or m-law pulse code modulation (PCM) channel at 8000 samples/second to and from a 40, 32, 24 or 16 kbit/s channel.
Recommendation G.726 was prepared by Study Group 15 of the Telecommunications Standardization Sector of the International Telecommunication Union (ITU-T) and was approved under the ITU's Resolution No. 2 procedure on the 14 of December 1990.
MIME Definition 3.1 audio/32KADPCM CCITT Recommendation G.726 [G726] describes the algorithm recommended for conversion of a 64 kbit/s A-law or u-law PCM channel to and from a 32 kbit/s channel (this is the same algorithm as described in the deprecated G.721).

AOL is feeding digital directly into their end, and the phone company's equipment doesn't limit this digital signal in the same way.
Obviously 56 kbit isn't harmful to anyone or anything, so these laws are probably going to be repealed or modified in the next year or so to allow the full bandwidth 56 kbit transmissions.
To achieve higher data rates than 64 kbits per second, you MUST have a new higher bandwidth phone line installed to your home (and pay for it) for a better connection to the internet.
