Universal Backup Transceiver for Cross-Chassis Communication Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network service providers face challenges when adding new transceivers to serve existing customers, as existing backup systems are limited to the same chassis, requiring reconfiguration or the inability to use existing spare transceivers for backup.
Innovation Solution
Implementing a system with control logic at the customer premises that detects communication errors and initiates a switch to a backup subscriber line, notifying the central office to route data through a spare transceiver, allowing seamless backup across different chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spare transceiver is used to backup multiple transceivers within the same chassis, then communication reliability is improved, but the system cannot accommodate new transceivers in different chassis without reconfiguration
Solution Approach 1:
The patent makes the backup transceiver universal by enabling it to backup transceivers across multiple chassis rather than being confined to a single chassis. The backup transceiver can dynamically assume the role of protecting different primary transceivers based on failure conditions, making the protection scheme adaptable to various chassis configurations and new service additions without requiring reconfiguration of the backup transceiver itself.
2Quantity of substance
If all chassis slots are occupied with active transceivers, then device density is improved, but the system cannot add new transceivers for additional subscriber lines
Solution Approach 1:
The backup transceiver serves multiple purposes: it acts as a standby for failed transceivers and can also be activated to provide additional service capacity when new subscriber lines are needed. Instead of requiring dedicated spare slots for expansion, the system uses the existing backup transceiver resource to fulfill both protection and expansion needs, allowing the network to grow without increasing physical infrastructure.
3Adaptability or versatility
If a new transceiver is inserted in a different chassis, then network expansion is enabled, but the existing spare transceiver cannot backup the new transceiver
Solution Approach 1:
The backup transceiver is designed with universal backup capability that allows it to protect primary transceivers regardless of which chassis they are located in. When a new transceiver is added to a different chassis, the backup transceiver can be reconfigured to provide protection for this new device, ensuring that backup coverage extends across the entire network infrastructure rather than being limited to a single chassis boundary.
Data Source
AI summary
A data communication system for communicating between a central office and a remote premises comprises a first transceiver, a second transceiver, and control logic. The first transceiver is coupled to a first communication connection extending from the central office to the remote premises and is configured to communicate with a central office transceiver. The second transceiver is coupled to a second communication connection extending from the central office to the remote premises. The control logic resides at the remote premises and is configured to detect an error condition associated with communication between the first transceiver and the transceiver located at the central office. The control logic is configured to transmit, in response to a detection of the error condition, a switch notification to the central office via the second transceiver and the second communication connection, wherein at least one component at the central office is configured to route data over the second communication connection in response to the switch notification.
