  I suspect it's around 30-40 hours of originating local calls per month for a
  flat rate resi subscriber.  But I don't have the real numbers; they're
  included in some rate filings, though.  Resi busy hour is the evening.
  But remember, telcos aren't asking for a rate hike for resi users who use
  modems to call ISPs.  They're asking for massive (several times current
  rates) surcharges on ISPs, whose hunt groups are usually like any other hunt
  group, engineered to handle the incoming load.  And barring that, some
  request outrageous rates from resi ISDN subscribers, on grounds that they
  are likely to be calling ISPs.  Of course this just puts more users on POTS
  and fewer on ISDN.
