In providing personal telephone calling capability as a service, for reliability purposes, it is necessary to have available several independent meet-me systems, to provide redundant capability in the event of a failure of any one of them. Each meet-me system has at least 1) one meet-me bridge and 2) its own telephone trunks directly connecting it to the telephone network over which it receives return calls. A problem with doing so is insuring that the return call is properly bridged to the caller's call when a) the telephone number for the return call is a predetermined translatable telephone number and b) the particular one of the meet-me systems to which the caller's call is connected is determined only upon receiving in the network the call placed by the caller. To overcome this problem, at least each time a caller's call is routed to different one of the meet-me systems, the network routing data base which translates the dialed translatable telephone number of the return telephone call into a network routing telephone number is updated so that it will direct a return call for the caller's call to the same meet-me system to which the caller's call was routed. Advantageously, a hot-spare standby is not needed for each meet-me system. Instead, one additional meet-me system provides the capability to back-up the failure of any single one of the other meet-me systems.

The invention provides a method and system for employing a communication system to mediate a transaction involving one of a plurality of files and programs corresponding to a plurality of applications residing on a single smart card. The invention uses a smart card gateway which provides a transparency in the communication between a caller station and a subscriber station and subscriber host associated with one of the applications. The smart card gateway facilitates transactions involving smart cards, and permits completed transactions to be recorded on the smart card as well as stored in a database associated with the smart card gateway.

The present invention discloses a thin-film solar cell, which comprises an electrode layer and a semiconductor layer. The semiconductor layer comprises a P-type layer, an I-type layer and an N-type layer. The P-type layer is disposed on the electrode layer. The I-type layer comprises an I-type amorphous silicon layer and an I-type polymorphous silicon layer. The I-type amorphous silicon layer is disposed on the P-type layer. The I-type polymorphous silicon layer is disposed on the I-type amorphous silicon layer. The N-type layer is disposed on the I-type polymorphous silicon layer. Wherein, the I-type polymorphous silicon layer generates a crystalline diffraction event and reduces photolysis reaction for enhancing the conversion efficiency of the thin-film solar cell.

It is known in the prior art to, when a telephone customer is unavailable to take a call, page the customer, thereby notifying the customer that a telephone call is waiting. The customer may then call in to a meet-me bridge to be connected to the incoming telephone call. However, if the customer does not respond to the page in time, prior art systems provide for the calling party's call to be routed to an alternate destination, e.g., a voice messaging system. The calling party's telephone call is thereby considered completed. If the customer thereafter becomes available, the customer is not connected to the caller's telephone call even if the caller is still connected to the alternate destination. In accordance with the principles of the invention, this problem is overcome by, in response to receipt of the telephone call from the customer, a) disconnecting the caller's telephone call from the alternate destination and b) connecting the caller's telephone call with the customer's call substantially contemporaneous with receipt of the customer's call.

We have recognized that in the prior art, to insure that there is at least some communication between the calling and called parties, when the called party is unavailable to take a call, the calling party may be connected to an alternate destination, e.g., a voice messaging system, and the caller's telephone call is considered completed. If the called party thereafter becomes available, the called party is not connected to the caller's telephone call. However, in accordance with the principles of the invention, this problem is overcome by, in response to receipt of an indication that the called party is available for a caller's telephone call after the caller's telephone call has already been connected to an alternate destination, a) disconnecting the caller's telephone call from the alternate destination and, instead, b) connecting it the called party, thus interrupting the connection between the caller and the alternate destination. Optionally, a tone or announcement may be supplied to the caller to indicate that the called party will now be connected "live" to the caller.
