Problems solved by technology

[0025] It can be seen from the above description that since the double-width MCH only provides Connector A, under the standard MicroTCA architecture, although various forms of MCH are supported, when a double-width MCH is inserted, Tier 2 does not provide connection resources, that is, it does not There is no Tier 2 connection part (Connector B), so both the switching plane and the management plane can only support up to 12 AMCs. Even if there is space left on the backplane, since there is only Connector A in the MCH, it cannot support more than 12 AMC; and, each MCH generally requires at least two tongues: Tongue 1 and Tongue 2. In the case of multiple tongues, a dedicated MCH connector is required, and the MCH connector is more expensive, which increases the cost of the system

Embodiment Construction

[0053] In order to make the above objects, technical solutions and advantages more clear, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The method for extending the MCH provided by the embodiment of the present invention is: setting a connecting part Connector B at Tier 2 of the double-width MCH, the Connector B is connected with the functional modules in the MCH, and the connection signal is provided through the Connector B.

[0055] The Connector B is the connection part of the Tier 2 layer, which is the connection part set on the second layer on the Tongue, and the Tongue can be one or more than one.

[0056] Figure 7 The structural diagram on a Tongue before and after the extended MCH provided for the embodiment of the present invention, such as Figure 7 As shown, (a) is a cross-sectional view of a Tongue of the MCH before expansion, and only the Tier 1 part of the Tongue has a co...

Abstract

The invention provides a method for extending commutative controller (MCH), MCH, a method for extending Micro Telecom Calculation Architecture (Micro TCA) and a Micro TCA system. A connecting part is set on the second layer of a dual-width MCH, wherein, the connecting part is connected to the function module of the MCH and provides connecting signal; as the Micro TCA system is being extended, a source module is to be extended based on the extension of the MCH. The method can be used for supporting more than 12 advanced mezzanine cards, as well as for realizing dual-Tongue function on one Tongue without using the MCH connecter in order to save cost. Thus, the extension of the MicroTCA system can be realized.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method for extending a switching control board (MCH, MicroTCA Carrier Hub) and the MCH, and a method for extending a small-sized physical-sized telecommunication computing architecture (MicroTCA, Micro Telecommunications Computing Architecture) system and the MicroTCA system. Background technique [0002] MicroTCA is a platform specification developed by the Peripheral Component Expansion Interface (PCI) Industrial Computer Manufacturers Association (PICMG, PCI Industrial Computer Manufacturers Group). MicroTCA uses Advanced Mezzanine Card (AMC, Advanced Mezzanine Card) to build a small-capacity and low-cost modular communication platform , mainly used in small telecommunication equipment such as central computer room or enterprise level communication equipment. The current standard specification version is PICMG MicroTCA.0R1.0 version. [0003] MicroTCA can have a variet...
