ONT Registration via Dedicated Control Path in PON
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing registration process for customer premises equipment in telecommunication access networks is time-consuming, cumbersome, and error-prone, lacking an efficient method to unambiguously assign equipment to a subscriber's data record in the central office.
Innovation Solution
A method is introduced that adds a low-capacity bidirectional communication path between the demarcation point unit and the subscriber's premises equipment, complementing existing end-to-end and low-capacity communication paths, allowing for unambiguous assignment and operation/maintenance purposes, utilizing existing communication protocols and demarcation point units under the network operator's responsibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual registration procedure is used where the customer enters a code received from the operator, then the equipment can be registered in the central office, but the process becomes time-consuming, cumbersome and error-prone
Solution Approach 1:
The customer premises equipment automatically performs registration by sending its own identification data through the optical connection to the central office, eliminating the need for manual code entry by the customer. The equipment serves itself to complete the registration process autonomously.
Solution Approach 2:
The manual mechanical process of code entry and registration is replaced by an automated electronic communication system. The identification data is transmitted electronically through the optical network infrastructure, substituting the manual registration procedure with an automated digital process.
2Productivity
If existing communication paths are used for equipment assignment, then network functions can be performed, but the assignment process lacks efficiency and clarity
Solution Approach 1:
The communication path is segmented into two distinct paths: an end-to-end path for high-capacity data transmission and a separate low-capacity path for control and management functions. This segmentation allows equipment assignment and network management to occur independently without interfering with data transmission, improving both efficiency and simplicity.
Solution Approach 2:
The demarcation point unit acts as an intermediary between the central office and the customer premises equipment. It receives and processes identification data from the equipment, facilitating the assignment process by mediating the communication between the equipment and the central office database.

AI summary
The invention relates to a method for performing network functions for a subscriber-sided (CPE) network access unit (ONT) in a telecommunication's access network with a central unit (CO, OLT), a distribution network (AN), and a multiple of network-sided network termination units (DPD) with subscriber-sided network access units (ONT) connected or connectable thereto, in which network a bidirectional communication path (1) is present between the central unit (CO) and that network-sided network termination unit (DPD), to which the subscriber-sided network access unit (ONT) under consideration is connected, in which for performing network functions a further bidirectional communication path (2) between the subscriber-sided network access unit (ONT) under consideration and the corresponding network-sided network termination unit (DPD) is used in connection with the bidirectional communication path (1) between the central unit (CO, OLT) and that network-sided network termination unit (DPD), as well as to a telecommunication's access network (FIG. 1), a central unit (CO, OLT), a network-sided network termination unit (DPD), and a subscriber-sided network access unit (ONT).
