The Public Switched Telephone Network (PSTN) provides plain old telephone phone service (POTS) to the residential customer over a twisted cable pair. The Federal Communication Commission (FCC) created regulations to identify and define ownership of the equipment and facilities for POTS services. The Demarcation point was established as the physical dividing line or boundary of POTS ownership between the PSTN and the customer. This Demarcation point establishes the phone service handoff and the associated responsibilities of performance, installation, and maintenance for the PSTN and the customer. A Demarcation point for POTS is typically represented by the PSTN or service provider's grey color network interface Device (NID) installed on the exterior side of a residential house. The customer installs their wire cable into the service providers RJ11 modular connector, which the RJ11 modular connector is located inside the NID. The Demarcation line is the RJ11 module connector.
Other types of a Demarcation point or line is the outside service plant (OSP) cabinets, which these OSP cabinets are centrally located to provide communication service to a serving area. In this application, the Demarcation point is a specified secured location inside the OSP cabinet where the customer only has access. This secured location may house a telephone wiring punch-down block (Type 66), a wire cable patch panel, or a fiber optic cable patch panel as the Demarcation point.
By way of further background, small form factor pluggable (SFP) Devices are used to provide a flexible means of providing communication services for the telecommunication network. The SFP Devices are typically deployed on communication network equipment such as an Ethernet access switch, Ethernet router, a broadband fiber multiplexer, or media converters. SFP Devices are designed to support optical and wired Ethernet, TDM SONET, Fiber Channel, and other communications standards. As disclosed in my U.S. Pat. No. 10,446,909, SFP Devices can also support a wireless interface, which wireless SFP (WSFP) Device can support IEEE802.11 (Wi-Fi), Bluetooth, LTE, 4G, 5G, and other wireless technologies. Due to its small and portable physical size, SFP Devices have expanded in specifications to address other applications. SFP Devices presently are defined for SFP, SFP+, QSFP, QSFP+, QSPF28, QSFP-DD and OSPF technologies. SFP Devices are standardized among equipment vendors and network operators to support interoperability. Due to the low cost, size, and interoperability, SFP Devices are used extensively in all communication service applications.
The telecommunication service and network have significantly evolved beyond the phone service. Telecommunication service provides voice, data, and video using wire cable, coax cable, fiber optic cables, and wireless service as a transport medium. The Demarcation point applies to all communication services, voice, data, video or any combination thereof. The Demarcation point location determination may also be subject to a minimum point of entry (MPOE). MPOE is the most practical location to establish a Demarcation point at the serving facility. The information infrastructure spans in size and complexity from a simple voice call to a myriad of complex and dynamic information flow for home automation, video streaming, ecommerce and cloud computing. In every information flow, there are boundaries which define privacy, ownership, and responsibilities between the communicating recipients. These boundaries are now virtual, logical, or physical and can be located anywhere.
Presently, there is a need to establish a Demarcation point for these boundaries. Concurrently, there Is a need to allow communications services to be monitored and/or tested to ensure the services are high in quality and reliable. The methods, systems, Devices and Circuitry disclosed herein fulfill these and other such needs.

The present disclosure relates to one or more methods, systems, devices and circuitry which establish a demarcation point or an extend demarcation point between networks and for the communication service to monitor or tap the communication services on either side of the network. The methods, systems, Devices and Circuitry of the present disclosure allow for the monitoring and/or testing of the communication service locally or remotely using any physical interface, including wire cable, optical cable, or wireless.
There are a number of advantages to remotely monitor the tapped communication services of a Demarcation Device. The monitored or tapped communication service is transported back to the network's facility, where the communication service can be analyzed in its entirety. The network can use and leverage the sophisticated and expensive test and monitoring equipment at their facility. The network can also leverage their complex and proprietary operation, administration, and maintenances process to test the Demarcation Devices, which these Devices may be located anywhere geographically. Without the complexity of having to locally collect and analyze the monitored communication services performance, the methods, systems, Devices and Circuitry of the present disclosure are of an extremely simplified design, are more reliable, are easier to install and service, and are very cost effective. In addition, the methods, systems, Devices and Circuitry of the present disclosure can be coordinated, implemented, and integrated into the network's infrastructure in a timely and operationally efficient manner.
The methods, systems, Devices and Circuitry of the present disclosure can establish a Demarcation point through an SFP Device. The methods, systems, Devices and Circuitry of the present disclosure do not disrupt or add impairments to the communication services when monitoring or when replacing the SFP monitoring Device. The SFP Device can provide the Demarcation point with a wired, coax, optical, or wireless interface with the appropriate SFP Device. Alternately, the methods, systems, Devices and Circuitry of the present disclosure can establish a Demarcation point through an SFP Port connector. The methods, systems, Devices and Circuitry of the present disclosure can also establish a Demarcation point through a monitoring and/or test interface or SFP Port connector.
The methods, systems, Devices and Circuitry of the present disclosure can also establish a Demarcation point for wireless services or an extended wireless Demarcation point. The present disclosure can provide a wireless Demarcation point or an extended wireless Demarcation point by simply connecting an appropriate wireless SFP into its Port connector. This can then be installed and implemented where needed due to the small mechanical size and simplicity of installation.
The methods, systems, Devices and Circuitry of the present disclosure can also provide a wireless Demarcation point by wireless signal conversion, which can perform a wireless-to-wireless signal conversion.
The methods, systems, Devices and Circuitry of the present disclosure can also provide two independent Demarcation points from two separate communication services. If the customer requests an additional service from the network, the methods, systems, Devices and Circuitry of the present disclosure can be provisioned to provide another communication service with a separate independent Demarcation point. This additional communication service interface can be physically independent and the serving network separate from the other Demarcation point communication service. The network would benefit with a quick increase in revenue and customer satisfaction.
The methods, systems, Devices and Circuitry of the present disclosure can also establish an additional Demarcation point to another network from another separate communication service.
The methods, systems, Devices and Circuitry of the present disclosure provide solutions to address the disadvantages and/or problematic issues with other Demarcation Devices or switches and/or other prior art communications methods, systems and Devices. The present disclosure also presents cost effective and operational efficient method(s), system(s) and Device(s) in achieving and enhancing the quality and reliability of present and future communication services.
The methods, systems, Devices and/or Circuitry and equipment of the present disclosure provide functionality which, inter aha:
The methods, systems, Devices, Circuitry and equipment of the present disclosure provide numerous advantages, novel features and/or improvements in providing various communication services and associated testing and maintenance for establishing a Demarcation for communication networks, including but not limited to providing the functionality of service monitoring via wireless. Discussed below and shown in the drawings are some of these advantages, novel features and/or improvements.
