Background

[0002] 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 Date Recue/Date Received 2021-06-29 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.

[0003] 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.

[0004] 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. Patent 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 Date Recue/Date Received 2021-06-29 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.

[0005] 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.

[0006] 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.

[0007] One example of a prior art Demarcation Device is illustrated in the diagram of Figure 1 (prior art), which depicts use of a "Universal Demarcation Point" Device for providing multiple services for residential customers. This Device provides audio, data, and video services through dedicated interfaces RJ type modular and coax. This hybrid cable is comprised of a combination Date Recue/Date Received 2021-06-29 of wire, power, and optical cables.

[0008] There are a number of disadvantages to a universal Demarcation type Device as shown in Figure 1 (prior art). First, this prior art Device provides a Demarcation point with dedicated services audio, data, and video services. If new services are added or changed after installation, the prior art Device must be powered off, disassembled, and updated for the new service. This service update may require the prior art Device to be updated at a service location or replaced with a new updated prior art Device. In either situation, the service is disrupted for an extend time. Second, this prior art Device does not provide an off-the-shelf service interface for any service or connector updates, replacements, or repairs. Third, this prior art Device test functionality involves disengaging the service by removing the plug or coax from the prior art Device connector for service isolation. The customer must then connect a test Device into the modular or coax connector to test their side of the Demarcation point. This prior art Device does not provide a Demarcation point with removable SFP type Devices or a Demarcation point with a differential signal Port interface. This prior art Device does not provide local or remote monitoring of either side of the Demarcation point and without disrupting service. This prior art Device does not allow remote injecting of signals to either side of the Demarcation point. This prior art Device does not provide a Demarcation point for monitoring and/or signal inject. This Device does not provide a Demarcation point for wireless services or a Demarcation point for wireless service with wireless-to-wireless signal conversion.

This prior art Device provides a method to detect optical signal faults from the recipient network. Upon detecting an optical loss of signal, the Date Recue/Date Received 2021-06-29 prior art Device will automatically perform an optical signal loopback to the service provider network.

[0010] There are a number of disadvantages to this prior art Device as shown in Figure 2 (prior art). First, this prior art Device cannot provide a Demarcation point interface for wire cable, coax cable, or wireless service. This prior art Device provides a Demarcation point with fixed fiber optic media interface. Second, this prior art Device provides a Demarcation point with fixed fiber optic interface connectors, such as SC, ST, or FC connectors.
Another prior art Device is required at the Demarcation point if a different fiber optic interface connector is required. This prior art Device does not provide local or remote monitoring of either side of the Demarcation point and without disrupting service. This prior art Device does not allow remote injecting of signals to either side of the Demarcation point. This prior art Device does not provide a Demarcation point for monitoring and/or inject. This Device does not provide a Demarcation point for wireless services or a Demarcation point for wireless service with wireless-to-wireless signal conversion.

[0011] Another prior art of a Demarcation Device is illustrated in the diagram of Figure 3 (prior art), which depicts use of a "Demarcation Switch" Device for selecting between different wireless service providers. This prior art Device connects via a high speed connector to two wireless routers to establish a Demarcation point between two wireless service providers. The prior art Device connects to an aggregation switch to transport the wireless service to another switch which distributes the wireless service among many Devices.

[0012] There are a number of disadvantages to a Demarcation switch type Device as shown in Figure 3 (prior art). First, this Device provides a Demarcation point by selecting between two wireless routers by means of a high-speed line. The prior art Device is then connected to other Date Recue/Date Received 2021-06-29 switches to distribute the wireless service to various Devices. The prior art Device connections among the switches and wireless routers are high speed fixed lines, either wired cable or optical cables, which are fixed signal and media interfaces. This prior art Device does not provide local or remote monitoring of either side of the Demarcation point and without disrupting service.
This prior art Device does not allow remote injecting of signals to either side of the Demarcation point. This prior art Device does not provide a Demarcation point for monitoring and/or signal inject. This Device does not provide a Demarcation point for wireless services or a Demarcation point for wireless service with wireless-to-wireless signal conversion. This prior art Device does not provide a redundant path to ensure service availability.

[0013] Another prior art Demarcation Device is illustrated in the diagram of Figure 4 (prior art), which depicts use of a "Demarcation" Device for interfacing different network services and signal formats for signal processing and forwarding to various Devices. This Device allows different communications services such as telephone switch phone services, internet, and wireless network to be received for signal format processing and forwarding.

[0014] There are a number of disadvantages to this type of Demarcation Device as shown in Figure 4 (prior art). First, this Device provides a Demarcation point which is dedicated for a network, namely the end user network. This Device cannot be used exclusively by the telephone switch network, internet network, or wireless network. This Device does not provide a Demarcation point with removable SFP type Devices or a Demarcation point with a differential signal Port interface. This Device does not provide signal monitoring and/or injecting. This Device does not provide a Demarcation point for monitoring and/or signal inject. This Device does not provide a Demarcation point for wireless services or a Demarcation point for wireless service with wireless-to-wireless signal conversion.

The Demarcation Device 100 of this embodiment establishes a Demarcation point or line 10 between a First Network 20 and a Second Network 30, specifically through a wireless SFP (WSFP) Device 116a.

The Device 100 also allows the wireless signal to be extended using two WSFP devices with the same wireless signal interface or WSFP device type.
An example is a WSFP Device 106a and a WSFP Device 116a supporting IEEE 802.11 (Wi-Fi) standard or a WSFP Device 106a supporting IEEE 802.11 (Wi-Fi), IEEE 802.15 (Bluetooth), 5G
and a WSFP Device 116a supporting only IEEE 802.11 (Wi-Fi). Although both WSFP
devices conform to the same wireless signal interface the WSFP devices may be provisioned to have different wireless signal formats or options. As an example, the IEEE 802.11 standard defines operation for wireless networks in both the 2.4GHz and 5GHz frequency ranges.
