Micro telecommunication computing architecture (micro TCA) system, carrier hub module and port configuration method of peripheral component interconnect (PCI)-E exchanger

Abstract

The invention relates to a micro telecommunication computing architecture (micro TCA) system, a carrier hub module and a port configuration method of a peripheral component interconnect (PCI)-E exchanger. The method comprises the following steps that: a configuration pin of the PCI-E exchanger is coupled to an input / output pin of a carrier manager; the carrier manager sends a control signal to the PCI-E exchanger so as to dynamically configure the each port of the PCI-E exchanger to be an uplink port or a downlink port. Under the condition of carrying out a small change on a hardware circuit, a control function of the carrier manager is fully used and configuration is performed on the port of the PCI-E exchanger so that a special configuration circuit does not need to be added and hardware cost of the system is reduced. And a port level state of the PCI-E exchanger can be controlled in real time and dynamic configuration can be performed on the port of the PCI-E exchanger. The different condition needs can be satisfied. The configuration is changed without reserving a part which is not used to feed or using a dial switch. Devices of a contact pin, a jump cap, a toggle switch and the like which are added to realize port configuration selection of the PCI-E exchanger can be effectively saved and PCB plate card space can be saved too.

Description

technical field [0001] The invention relates to a port configuration method, in particular to a port configuration method of a micro-telecom computing framework system, a carrier board hub module and a PCI-E switch. Background technique [0002] The Micro Telecommunication Computing Architecture (Micro TCA, Micro Telecommunications Computing Architecture) system is a platform specification developed by the Peripheral Component Interconnect (PCI, Peripheral Component Interconnect) Industrial Computer Manufacturers Association (PICMG, PCI Industrial Computer Manufacturers Group). AMC (Advanced Mezzanine Card) module to build a small-capacity and low-cost large-scale communication platform, which is mainly used in small telecommunication equipment or enterprise-level communication equipment such as central computer rooms. [0003] A micro telecom computing architecture system usually includes a chassis, a backplane, a power module, a carrier hub module (MCH, MicroTCA Carrier Hu...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a port configuration method of a PCI-E switch, which aims to solve the problem of the port configuration of the PCI-E switch in the prior art, where the configuration cannot be changed, that is, the properties of the port cannot be changed, Unable to adapt to new needs; professionals are required to realize it, and ordinary users do not know how to operate, which is not convenient for large-scale promotion; for multi-port carrier board hub modules, a large number of toggle switches are required, which is troublesome to operate; switch materials occupy PCB Board space, small boards are difficult to implement, etc.
