`communication network using a tandem access
`controller,

`wherein the PSTN communication network
`comprises edge switches connected to telephones
`on one side and PSTN tandem switches on the

`“Until now, optional features were provided by the
`local service telephone company (telco) through the
`edge switch at the central office (CO). It was not
`possible to provide optional features through any other
`means. Control of these features was done through the
`first party (calling party) or the second party (called
`party), or worse yet, manually by calling the business
`office.
`In the past, numerous devices have been built that
`allow the connection of two lines together at an edge
`switch. These devices can be used to add features to a
`telephone network by receiving a call on one line and
`then dialing out on another line. The problem with
`these devices is that, because they are connected
`through an edge switch, transmission losses and
`impairments occur, degrading the overall connection.
`In addition, signaling limitations prevent full control,
`by the subscriber or the system, over the call.
`The invention described herein connects at the tandem,
`thereby eliminating these problems.”

`“Fig. 1 uses a public internet portal connected via a
`data link to the TAC 10 or other interface system. As
`a registered subscriber, a user logs onto the portal (Fig.
`3) and is granted access, allowing the user to make
`additions or changes to features such as speed calling,
`call forwarding, selection of such descriptors as time
`of day, busy status, callerID status, etc.”
`“Fig. 1 illustrates the preferred method for an
`authorized subscriber to modify the 3rd-party control
`criteria by means of the world wide web 22 (and web
`server 23) using an internet browser. By "authorized"
`we mean a subscriber who is registered and has
`"logged-in" with appropriate security and password
`controls. The subscriber 12 interacts with the web 22
`via the Internet to quickly and easily specify the
`enhanced 3rd-party call control features. Web 22 then
`relays this information, in appropriate form, to the
`TAC 10.”
