Embodiment Construction

[0022] The main idea of ​​the present invention is: by providing a method and device for redundant backup of E1 / T1 interface, the redundant service interface is fully utilized, and when the E1 / T1 electrical interface fails, such as failure or damage, the service cannot be transmitted, Switch from the failed E1 / T1 electrical interface to these redundant service interfaces, thereby protecting the successful transmission of E1 / T1 services without increasing the cost of E1 / T1 function cards.

[0023] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments. Such as figure 2 Shown is the functional block diagram of the existing E1 / T1 function card. The E1 / T1 function card consists of one or n pieces of E1 / T1 interface chips, and one or m pieces of E1 / T1 outlets, and of course also includes system side interfaces and E1 / T1 service interfaces.

Abstract

The invention relates to an E1 / T1 interface redundancy backup method, which comprises that preset availably assessible amount of E1 / T1 business is determined; actual availably assessible amount of E1 / T1 business is determined; the preset availably assessible amount of E1 / T1 business is compared with the actual availably assessible amount of E1 / T1 business to obtain difference value; a redundancy business interface of the difference value is determined; when falling news of an E1 / T1 electrical interface is received, an E1 / T1 business redundancy backup interface is determined from the redundancy business interface. The invention also relates to an E1 / T1 interface redundancy backup device, which comprises an E1 / T1 amount of business determination module, a redundancy business interface determination module, and a business backup interface module. Therefore, the method can realize redundancy backup function of the E1 / T1 electrical interface in an E1 / T1 functional card based on no adding cost of the E1 / T1 functional card when the E1 / T1 electrical interface goes wrong or breaks down.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for redundant backup of an E1 / T1 interface and a redundant backup device for an E1 / T1 interface. Background technique [0002] E1 / T1 electrical interfaces are widely used in mobile communication networks and are important bearer interfaces for communication services. Communication equipment is generally composed of a backplane (motherboard) and a variety of function cards, among which the E1 / T1 electrical interface function is generally realized by the E1 / T1 function card, usually one E1 / T1 function card integrates multiple E1 / T1 services, integrated There can be at least 8 channels of multi-channel E1 / T1 services, and up to 126 channels of services. [0003] In engineering applications, failure or damage of the E1 / T1 electrical interface is inevitable due to various reasons. There are currently two solutions. One is to enable the board-level protection function of ...
