Abstract
Abstract A telephone status recognition and bypass system includes a plurality of status recognition units, and a controller. Each status recognition unit interfaces a subscriber's telecommunication line between a plurality of peripheral services and to a switch network, and includes status monitoring circuits and an SRU switch. The status monitoring circuits monitor status of calls incoming to and outgoing from the service subscriber, and produces status signals representative thereof. The SRU switch switchably interconnects the service subscriber, the switch network, and the peripheral services, for telecommunications in response to switching control signals. The controller is responsive to the status monitoring circuits, and produces switching control signals as a function of the status signals. The controller causes the SRU switch to interconnect the service subscriber to the selected peripheral service, thereby passing the switch network, when the status monitoring means produces status signals representative of an outgoing call from the service subscriber to the peripheral service.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
208 words
A telephone status recognition and bypass system for interfacing, at a central office, each of at least one remotely located service subscriber's telecommunication lines to at least a first remotely located peripheral service over a first alternate trunk, and to a switch network at the central office, including: at least one status recognition unit (SRU) including: signaling monitoring means interfaced to a service subscriber's telecommunication lines at the central office for monitoring signaling of outgoing calls from the service subscriber, and for producing signaling signals representative thereof; and SRU switch means interfacing the central office switch network, service subscriber`s telecommunication lines and first alternate trunk, at the central office, for switchably interconnecting the service subscriber, the switch network, and a first remotely located peripheral service for telecommunications in response to switching control signals; and control means responsive to the signaling monitoring means for producing switching control signals as a function of the signaling signals, wherein the control means causes the SRU switch means to interconnect the service subscriber to the first remotely located peripheral service over the first alternate trunk, thereby bypassing the central office switch network, when the signaling monitoring means produces signaling signals representative of an outgoing call from the service subscriber to the peripheral service.
Claim 2
Dependent Claim
208 words
A telephone status recognition and bypass system for interfacing, at a central office, each of at least one remotely located service subscriber's telecommunication lines to at least a first remotely located peripheral service over a first alternate trunk, and to a switch network at the central office, including: at least one status recognition unit (SRU) including: signaling monitoring means interfaced to a service subscriber's telecommunication lines at the central office for monitoring signaling of outgoing calls from the service subscriber, and for producing signaling signals representative thereof; and SRU switch means interfacing the central office switch network, service subscriber`s telecommunication lines and first alternate trunk, at the central office, for switchably interconnecting the service subscriber, the switch network, and a first remotely located peripheral service for telecommunications in response to switching control signals; and control means responsive to the signaling monitoring means for producing switching control signals as a function of the signaling signals, wherein the control means causes the SRU switch means to interconnect the service subscriber to the first remotely located peripheral service over the first alternate trunk, thereby bypassing the central office switch network, when the signaling monitoring means produces signaling signals representative of an outgoing call from the service subscriber to the peripheral service.
Claim 3
Dependent Claim
133 words
The telephone status recognition and bypass system of claim 1 wherein: the system further interfaces the service subscriber to a second remotely located peripheral service over a second alternate trunk; the SRU switch means further includes means interfacing the central office switch network, service subscriber's telecommunications lines and the second alternate trunk, at the central office, for switchably interconnecting the service subscriber, the switch network, and the second remotely located peripheral service over the second alternate trunk, for telecommunications in response to switching control signals; and the control means causes the SRU switch meant to interconnect the service subscriber to the second remotely located peripheral service over the second alternate trunk when the signaling monitoring means produces signaling signals representative of an outgoing call from the service subscriber to the second peripheral service.
Claim 4
Dependent Claim
39 words
The telephone status recognition and bypass system of claim 2 wherein the signaling monitoring means further includes means for monitoring signaling of the service subscriber's incoming calls through the central office switch network and produces signaling signals representative thereof.
Claim 5
Dependent Claim
63 words
The telephone status recognition and bypass system of claim 3 wherein the control means causes the SRU switch means to interconnect the service subscriber's incoming calls to either the first or second peripheral services when the signaling monitoring means produces signaling signals representative of an incoming call to the service subscriber, while producing signaling signals indicating that the service subscriber's line is busy.
Claim 6
Dependent Claim
64 words
The telephone status recognition and bypass system of claim 3 wherein the control means causes the SRU switch means to interconnect the service subscriber's incoming calls to either the first or second peripheral services when the signaling monitoring means produces signaling signals representative of incoming calls to the service subscriber, and signaling signals indicating that the service subscriber is not answering the incoming call.
Claim 7
Dependent Claim
47 words
The telephone status recognition and bypass system of claim 1 wherein the control means causes the SRU switch means to interconnect the service subscriber to the first peripheral service when the signaling monitored means produces signaling signals representative of a prohibited outgoing call from the service subscriber.
Claim 8
Dependent Claim
53 words
The telephone status recognition and bypass system of claim 1 and further including a plurality of status recognition units, each of which is connected to the control means at the central office and interfaces a service subscriber's telecommunication lines to at least a first peripheral service and to the central office switch network.
Claim 9
Dependent Claim
20 words
The telephone status recognition and bypass system of claim 1 wherein the control means includes memory means for storing data.
Claim 10
Dependent Claim
31 words
The telephone status recognition and bypass system of claim 8 wherein the control means causes data representative of outgoing calls from the service subscriber to be stored in the memory means.
Claim 11
Dependent Claim
34 words
The telephone status recognition and bypass system of claim 9 wherein the control means causes data representative of phone numbers of outgoing calls from the service subscriber to be stored in the memory means.
Claim 12
Dependent Claim
35 words
The telephone status recognition and bypass system of claim 9 wherein the control means causes data representative of a time duration of outgoing calls from the service subscriber to be stored in the memory means.
Claim 13
Dependent Claim
21 words
The telephone status recognition and bypass system of claim 8 and further including data terminal means for programming the control means.
Claim 14
Dependent Claim
85 words
The telephone status recogniton and bypass system of claim 1 wherein the signaling monitoring means includes: a dial tone detector for producing signals representative of a dial tone on the service subscriber's line; a ring decoder for producing signals representative of a ringing voltage on the service subscriber's line indicative of an incoming call; a tone/pulse decoder for producing signals representative of outgoing calls from the service subscriber; and a loop current detector for producing signals representative of loop current on the service subscriber's line.
