Prism I

.10 Option H (MCI Prism I)

Option H is a one-way, multipoint service requiring the customer to originate calls via dedicated facilities between the customer's premises and the Companys terminal location and allowing the termination of calls via a combination of Company-provided intercity facilities and local business telephone lines or other exchange access facilities. Prism I has five distance-sensitive pricing Ranges from each originating area code with total coverage on every line. These Ranges, as determined for each originating and terminating area code are shown in Section C-12, Table V, Part F. All Option H calls are subject to a 6-second minimum duration and are rounded to the next higher 6-second increment, except that calls terminating to the international locations listed in Part E of Table V are calculated on a 30-second duration basis, with additional 6-second increments. If the computed charge includes a fraction of a cent, the fraction is rounded to the nearest whole cent.

In addition to other service-related charges under this option, FUSF, CAC, Administrative Expense Fee and CCRC apply.
