Claim 12

Dependent Claim 48 words

A method as recited in claim 1, wherein: the method further comprises the step of associating handsets with the SIMs; the selecting step identifies one of the handsets associated with the selected one of the SIMs; and the coupling step couples the identified handset to the selected transceiver.

Claim 13

Independent Claim 158 words

A method for operating a multi-channel subscriber exchange that couples to a network that provides communication and authentication services for subscribers over channels such that the communication services are provided during incoming and outgoing calls, the method comprising the steps of: accessing a quantity M of subscriber identity modules (SIMs), where M is an integer number; controlling a quantity N of transceivers, where N is an integer number less than M; associating a handset with each of the SIMs; selecting one of the SIMs and one of the transceivers at an initiation of one of the calls; identifying one of the handsets associated with the selected one of the SIMs at the initiation of the one of the calls; coupling the identified handset and the selected SIM to the selected transceiver at the initiation of the one of the calls; and decoupling the selected SIM from the selected transceiver at a termination of the one of the calls.

Claim 14

Independent Claim 158 words

A method for operating a multi-channel subscriber exchange that couples to a network that provides communication and authentication services for subscribers over channels such that the communication services are provided during incoming and outgoing calls, the method comprising the steps of: accessing a quantity M of subscriber identity modules (SIMs), where M is an integer number; controlling a quantity N of transceivers, where N is an integer number less than M; associating a handset with each of the SIMs; selecting one of the SIMs and one of the transceivers at an initiation of one of the calls; identifying one of the handsets associated with the selected one of the SIMs at the initiation of the one of the calls; coupling the identified handset and the selected SIM to the selected transceiver at the initiation of the one of the calls; and decoupling the selected SIM from the selected transceiver at a termination of the one of the calls.

Claim 15

Dependent Claim 95 words

A method as recited in claim 12, wherein the accessing step comprises the step of extracting personal identification numbers (PINs) from original SIMs that are inserted into subscriber identity card access ports, and the method further comprises the steps of: prompting for the entry of the PINs while the original SIMs are inserted into the subscriber identity card access ports to authorize relinquishing the original SIMs; and relinquishing the original SIMs from the subscriber identity card access ports if data entered in response to the prompting step matches the PINs extracted from the original SIMs.
