 Customers of ISACOMM understood their relationship to be with ISACOMM, not SBS.As an interstate carrier, ISACOMM was subject to regulation by the Federal Communications Commission and had to file its own tariffs, although progressive deregulation of the industry made the tariff process increasingly irrelevant.The original target market for ISACOMM was the insurance industry, with whom the ISACOMM management had strong connections arising from the history of ISA.
