These modems are in use now.

Modem Who uses it Provided by

Cable: Cable Provider: Time Warner's Road Runner/Adelphia

DSL: Phone Company: SBCYahoo/BellSouth

56k: Dial up: AOL/NetZERO


Answer

Of the top of my head:
Standard telephony modems, from 200 baud to 56k
ISDN, at about 122k or so
DSL, Cable, Satellite, Powerline...there are probably also a lot of subtypes that I've Never Heard Of.

T1 and T3 are both examples of high-speed telephone lines. Both of them may be used to provide broadband internet access. Technically, a T1 connection is a fiber-optic or copper line that is separate from the regular phone line. However, the T1 line can be used for both broadband Internet access in addition to phone purposes.

T1 and T3 lines are commonly used by businesses because they offer very fast data transfer rates. This is appealing to businesses that need to transfer large amounts of data each day. Additionally, T lines provide very reliable forms of Internet access, with "always on" capability and very few incidences of lost Internet connections. In terms of speed, T1 lines operate at 1.5 Mbps, and T3 lines operate at 44.6 Mbps. In other words, T3 lines are about 30 times faster than T1. These high speeds are very useful for heavy Internet traffic situations as well as for situations in which a network must be accessed by a larger number of users. A T1 line operating at full capacity can accommodate up to 24 users working at 64 Kbps. http://www.broadbandinfo.com/cable/broadband/what-are-t1-and-t3-internet-connections-and-who-uses-them.html
