Channel bonding

A technology that combines two telephone lines into a single channel, effectively doubling the data transfer speeds. To take advantage of channel bonding, you need two modems and two telephone lines. If both modems offer 56 Kbps speeds, for example, bonding two modems together would give you a 112 Kbps Internet connection, comparable to an ISDN connection.Modems that support channel bonding first emerged at the end of 1997 and are expected to become more popular in 1998. One stumbling block, however, is that there are many incompatible channel bonding systems, and your ISP must support the same system as your modems.
