Transceiver Initialization via Handshake Information Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed communication systems like G.fast and G.hn, multiple transceivers face challenges in simultaneous handshaking due to frequency band conflicts, leading to increased time and interference when higher frequency transceivers need to use lower frequency bands for handshaking, disrupting communication.
Innovation Solution
A method where a single transceiver transmits initialization information for multiple transceivers over the same physical communication medium using a single set of tones, embedding handshake information for multiple transceivers within the initialization process, allowing simultaneous initialization without interfering with other transceivers sharing the medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher frequency transceivers use lower frequency bands for handshaking, then handshaking can be completed, but communication time increases and interference occurs
Solution Approach 1:
The patent combines multiple handshaking processes into a single unified initialization sequence. The central office equipment coordinates handshaking for multiple transceivers simultaneously by merging their handshake messages into a single communication exchange, eliminating the need for sequential handshaking and reducing total initialization time.
Solution Approach 2:
The patent implements a universal initialization protocol that can handle multiple transceiver types and frequency bands simultaneously. The handshaking mechanism is designed to be frequency-agnostic, allowing transceivers operating at different frequencies to participate in the same initialization sequence without requiring separate dedicated procedures for each frequency band.
2Productivity
If multiple transceivers perform handshaking simultaneously on the same medium, then initialization speed increases, but interference and errors increase
Solution Approach 1:
The patent introduces central office equipment as an intermediary that mediates the handshaking process between multiple transceivers. The central office receives, coordinates, and manages the handshake messages, ensuring that multiple transceivers can initialize simultaneously without interfering with each other. This intermediary prevents direct conflicts between transceivers while maintaining high initialization speed.
3Reliability
If individual handshaking is performed for each transceiver, then communication reliability is maintained, but time consumption increases
Solution Approach 1:
The patent merges multiple individual handshaking processes into a single coordinated initialization sequence managed by the central office. Instead of each transceiver performing separate handshaking exchanges, the central office consolidates these exchanges into one unified process, maintaining reliability through centralized coordination while dramatically increasing initialization throughput.

AI summary
Methods, systems, and computer readable medium for initializing communication for multiple transceivers. In one aspect, a method includes launching an initialization process of a first transceiver. The initialization process includes obtaining, for a second transceiver, a set of handshake information and inserting the set of handshake information of the second transceiver into one or more registers that are transmitted with first handshake information of the first transceiver during initialization of the first transceiver. The initialization process includes initiating a communications channel for the second transceiver over the same physical communications medium using the set of handshake information that was inserted into the one or more registers, including transmitting, by the first transceiver, the first handshake information of the first transceiver together with the set of handshake information for the second transceiver over the same physical communications medium using the given set of tones.
