`The PSTN tandem switch 16 directs a first call (from the

`subscriber's public phone number) to the TAC 10, which
`in turn places a second call, subject to 3rd-party control
`information, to the subscriber's "private" phone number
`without yet terminating the first call. The TAC 10 is
`connected within the subscriber's local service area so
`calls from TAC 10 to the subscriber do not incur a toll.
`When the subscriber 12 terminates (or answers) the
`second call, the TAC 10 terminates the first call and
`connects it to the second call, thereby connecting the
`calling party 20 to the subscriber 12. Hence, the calling
`party essentially calls the TAC 10, using the subscriber's
`public phone number, and the TAC 10, after processing
`the call using the selected features, calls the subscriber, as
`appropriate, using the subscriber's private phone number
`and connects the two calls.”
