Abstract
Abstract An automatic metering information collection system and method in which a remotely controllable line multi-interface at a customer's local multi-interfacing multiport switch responds to an interface selection message from a metering information collection computer at a utility service provider location to connect the hybrid digital/analog customer telephone line to a selected one of a plurality of available interfaces compatible with the type of interface employed by the meter until the metering information is conveyed to the collection computer and then automatically returns the customer's line to a default interface used by the other types of telephonic equipment on the customer's line.

Claim 10
Dependent Claim
37 words
The method of claim 8 in which the step of responding includes the step of selectively switching the selected one interface between the customer telephone line and the local multiport switch when the selection switch is actuated.
Claim 11
Dependent Claim
52 words
The method of claim 8 in which the step of responding includes the step of selectively switching all the remaining interfaces of the plurality of available interfaces other than the one selected interface out of circuit between the customer telephone line and the local multiport switch when the selection switch is actuated.
Claim 12
Dependent Claim
32 words
The method of claim 1 including the step of automatically interfacing the customer line with a default interface of the plurality of available interfaces after the step of transmitting has been completed.
Claim 13
Dependent Claim
83 words
The method of claim 11 in which the step of automatically interfacing the customer line with the default interface includes the steps of preselecting the default interface from the plurality of interfaces available, storing the identity of the default interface that has been preselected, and switching the default interface into circuit with the customer line in lieu of the selected interface after conclusion of the step of transmitting if the selected interface has an identity other than the identity of the default interface.
Claim 14
Dependent Claim
50 words
The method of claim 1 including the steps of sending an access code identifying one of the available interfaces from the customer line when a call is initiated from the customer line, and interfacing the customer telephone line to the available one of the interfaces identified by the access code.
Claim 15
Dependent Claim
51 words
