Abstract
The utility model discloses an eternet port branch protective switching device for digital synchronizing system equipment. The port is provided with standby processing boards; all the outlet boards of the port are connected with processing boards via working bus lines; a PHY chip is positioned on the outlet board of the port; the outlet boards are connected with the standby processing boards via point-to-point branch protective switching bus lines. The utility model is provided with the point-to-point TPS lines between the ethernet port outlet boards of the SDH device and the ethernet processing boards, i.e., each of the outlet boards is respectively connected with the standby processing board alone, and thus no matter which processing board fails, the outlet board is connected with the standby processing board conveniently and directly. Since the PHY chip is positioned on the processing board, the design of the outlet board is greatly simplified, making the outlet board as a passive single board, and the outlet board is durable, better realizing the TPS function.
Description
Technical field:
The utility model relates to a kind of ethernet port Tributary Protection Switch device of synchronizing digital hierarchy equipment.
Background technology:
Present SDH (Synchronous Digital Hierarchy; SDH (Synchronous Digital Hierarchy)) equipment generally only relates to TPS (the Tributary Protect Switch of ports such as E1, E3, E4, STM-1E; Tributary Protection Switch) protection; as shown in Figure 1, general SDH branch service inserts and is divided into two parts: outlet board and disposable plates.Wherein, outlet board is access and the output of finishing branch service, and the TPS switching action, generally do not have active device, thereby reliability is very high.Disposable plates is finished Business Processing, the structure more complicated, and failure rate is higher.The principle of the E1 TPS scheme of traditional SDH equipment is: when system control unit perceives after certain piece branch road disposable plates breaks down, then system control unit is understood the professional cross unit of reporting system, the switching services of fault branch disposable plates is handled baffle, i.e. SLOT1 among the figure to branch road; Simultaneously, system control unit also needs all service configuration informations of fault branch disposable plates are downloaded in the branch road processing baffle simultaneously; In addition, system control unit also needs to control outlet board, the interface of outlet board is switched to branch road from the fault branch disposable plates handles on the baffle.This has just formed the TPS to the E1 of SDH equipment.But the TPS protection of data services such as SDH equipment ether does not still relate to.This situation occurring in many ways and reason causes, at first is that each SDH of producer equipment supports that the time of Ethernet service is also very short; Ethernet service all is BEST EFFORT business usually on the other hand, and is not high to the device level backup request; The TPS scheme that to also have a reason be exactly the ether port implements more complicated.
The utility model content:
At the existing problem and shortage of above-mentioned existing SDH equipment ethernet port, of the present utility model day the ethernet port Tributary Protection Switch device that provides a kind of synchronizing digital hierarchy equipment.
The utility model is achieved in that a kind of ethernet port Tributary Protection Switch device of synchronizing digital hierarchy equipment; described port is provided with standby disposable plates; link to each other by working bus between all outlet boards of port and the disposable plates; PHY (physical layer) chip places on the disposable plates of port; it switches device is relay; the port external interface is an optical module; described optical module is connected with described relay, and the Tributary Protection Switch bus by point-to-point between all outlet boards and the standby disposable plates links to each other.
Further, described point-to-point Tributary Protection Switch wire laying mode is specially all outlet boards and is connected separately respectively with standby disposable plates.
Further, described port external interface can also be RJ45, and it is connected with described relay by transformer.
Further, described standby Ethernet disposable plates can also be more than 1 or 1.
The utility model is provided with the Tributary Protection Switch line of point-to-point between the ethernet port outlet board of SDH equipment and Ethernet disposable plates, be that each outlet board is connected with standby disposable plates separately respectively, like this, problem has appearred in the whichever disposable plates, all can directly be connected with standby disposable plates easily; The PHY chip is placed on the disposable plates, can simplify the design of outlet board greatly, outlet board can be passive veneer just also like this, and outlet board is not just allowed perishable, thereby can better realize the TPS function.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is made detailed description.
Fig. 1 is the TPS implementation structure schematic diagram of current SDH equipment E1;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is business board of the present utility model and disposable plates connection diagram.
Embodiment:
As shown in Figure 2, the utility model forms for improving on the scheme basis of the TPS of SDH equipment E1, by the TPS line is set, the wire laying mode of these TPS lines employing point-to-points between the outlet board of SDH equipment ethernet port and disposable plates.When system control unit perceives after certain piece Ethernet disposable plates breaks down, then system control unit can the professional cross unit of reporting system, the switching services of fault Ethernet disposable plates to the standby disposable plates of Ethernet, i.e. SLOT1 among the figure; Simultaneously, system control unit also needs all service configuration informations of fault Ethernet disposable plates are downloaded in the standby disposable plates of Ethernet simultaneously; In addition, system control unit also needs to control outlet board, and the interface of outlet board is switched on the standby disposable plates of Ethernet from fault Ethernet disposable plates.The main cause that adopts the wire laying mode of point-to-point is because the cabling operating rate is very high between disposable plates and outlet board, is not suitable for adopting bus form.
Here, the device of switching of the present utility model is a relay; Standby disposable plates can also be a polylith, and itself and other disposable plates and connecing gets final product, and the TPS line is connected with these standby disposable plates respectively and gets final product.
For the outlet board that makes ethernet port is passive veneer, the PHY chip is placed on the disposable plates, and, use optical module as external interface of the present utility model; Certainly, also can be with RJ45 as external interface of the present utility model, but on working bus that between the outlet board of SDH equipment ethernet port and disposable plates, is connected and the TPS bus transformer is set.As shown in Figure 3, support above-mentioned two types external interface, also transformer can be arranged between external interface and the relay for making the utility model.The PHY chip is placed on the disposable plates, thus not only outlet board can be that passive veneer is not allowed perishable, and can simplify the design of outlet board greatly, can better realize the TPS function.
