Telephony Port Ringing Manager Peak Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power management in telephony systems is inefficient due to varying power consumption across different subsystems, particularly during ringing and off-hook states, leading to increased peak power consumption and costs.
Innovation Solution
Implementing intelligent ringing management through a port manager and ring manager that monitor and control the power distribution across multiple ports, delaying initial cadence onset during low power availability and prioritizing cadence transitions to minimize peak power usage without causing cadence distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple ports are rung simultaneously, then service capability is improved, but peak power consumption increases
Solution Approach 1:
The patent implements periodic ringing cadence with on-periods and off-periods, allowing ports to be rung in staggered cycles rather than simultaneously. The ring manager delays initial cadence onset and schedules cadence transitions to distribute power consumption over time, enabling multiple ports to be served while maintaining peak power within limits.
2Power
If power distribution is delayed to manage peak consumption, then power consumption is reduced, but ringing service quality deteriorates
Solution Approach 1:
The system dynamically adjusts the initial cadence delay and cadence transition timing based on real-time power availability. The ring manager monitors power conditions and adapts the ringing schedule, allowing ports to start ringing earlier when power is abundant and delaying when power is constrained, thereby maintaining service quality while managing peak consumption.
Solution Approach 2:
The ring manager implements feedback control by monitoring power availability and adjusting cadence scheduling accordingly. When power becomes available, delayed ports are activated; when power is constrained, activations are postponed. This closed-loop control ensures ringing service quality is maintained within power constraints.
3Power
If cadence transitions are prioritized to minimize peak power, then power efficiency is improved, but cadence distortion may occur
Solution Approach 1:
The ring manager performs preliminary scheduling of cadence transitions, planning ahead which ports will transition next based on predicted power availability. By pre-scheduling transitions and preparing the ringing sequence in advance, the system can efficiently manage power while maintaining proper cadence timing and avoiding distortion.

AI summary
A network device has at least two communication ports to allow the device to communicate with at least two telephony devices. The device has a ring manager to determine if any of the communication ports are silent ports ready to transition from silent to ringing, determine if there is power available to transition the silent ports to ringing ports, transition silent ports to ringing ports until an amount of available power is depleted, and queue remaining silent ports until power becomes available, such that silent ports in the queue may experience cadence distortion.
