Ken and Angelo,

    This practice is apparently called "channel bonding," "modem bonding," or "dual bonding." Here are some relevant links:

1. http://en.wikipedia.org/wiki/Channel_bonding

2. http://www.eeproductcenter.com/encyclopedia/defineterm.jhtml?term=modem+teaming

3. http://findarticles.com/p/articles/mi_hb5025/is_199711/ai_n18233824

4. http://dictionary.zdnet.com/definition/channel+bonding.html

    IIRC, there may have once been a "How-to" on TLDP.org or a similar site.
