Telco Hub Interposer Module for Chassis I/O Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server-based computer systems, such as IBM BladeCenter, lack support for telephone company (telco) style interfaces and front panel input/output (I/O) due to air filter placement and lack of defined cut-outs, limiting integration with telephony data processing and requiring support for redundancy and switching of telco traffic.
Innovation Solution
The introduction of an interposer module that acts as a carrier card, allowing mezzanine modules with telco I/O interfaces to be coupled to the backplane, enabling the processing of telephony data and providing redundancy and switching capabilities within the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If server-based computer systems use standard chassis design with air filter placement, then cooling function is achieved, but front panel I/O support is limited and telco interfaces cannot be integrated
Solution Approach 1:
The chassis is segmented into functional zones: a front panel with defined cut-outs for I/O interfaces, a rear panel with telco interface support, and internal air filter placement zones. This segmentation allows each area to be optimized for its specific function without compromising the others, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent introduces front panel I/O support in addition to rear panel telco interfaces, adding a spatial dimension to the I/O architecture. This multi-dimensional approach to interface placement enables both telco and standard I/O capabilities simultaneously, improving adaptability while maintaining manageable chassis complexity through standardized cut-out designs.
2Adaptability or versatility
If server-based computer systems lack defined cut-outs for front panel I/O, then manufacturing is simpler, but integration with telephony data processing is limited
Solution Approach 1:
The front panel cut-outs are designed as standardized, universal openings that can accommodate various I/O interface types. This universal design enables telephony data processing integration while maintaining ease of manufacture through standardized manufacturing processes. The same cut-out design can support different interface configurations without requiring custom manufacturing for each scenario.
3Reliability
If server-based computer systems do not support redundancy and switching of telco traffic, then device complexity is lower, but reliability for telephony data processing is insufficient
Solution Approach 1:
The patent introduces switching capabilities as an intermediary function that manages telco traffic between multiple interfaces and processing units. This intermediary switching layer enables redundancy and traffic management without requiring complex reconfiguration of the entire system. The switching function acts as a mediator that simplifies the implementation of reliability features while maintaining manageable device complexity through dedicated switching hardware or software modules.

AI summary
A telco hub in a chassis having a front side and a rear side, where the chassis includes a midplane having a first side and a second side, the telco hub includes an interposer module coupled to slidably insert into a switch slot on the rear side and connect to the second side of the midplane, a mezzanine module coupled to the interposer module, where the mezzanine module includes a telco I/O interface, where the mezzanine module is coupled to receive non-packetized telephony data. The telco hub is coupled to convert the non-packetized telephony data to packetized data, and communicate the packetized data to one or more of a plurality of payload modules over a switched fabric on the midplane, where each of the one or more payload modules is coupled to the first side of the midplane via a payload slot on the front side of the chassis.
