Description
The present invention relates to field of telecommunications, be specifically related to stored-program control exchange, Remote Interface Unit and SDH (synchronous digital hierarchy) transmission equipment, more particularly, relate to the remote-end integrated unit and the network-building method thereof that integrated services such as voice, data and image are handled ability that have concurrently of equipment such as integrating service access, SDH transmission, power supply, distributing frame, environmental monitoring.
At telecommunications network, especially in rural telephone network, user terminal is commonly referred to as " last kilometer " of telecommunications network to the circuit between the switch.This section circuit is because average line is long, constructional difficulties, cause track investment very big, generally to account for about 30% of gross investment, the track investment problem causes the increasing large capacity exchanger number of having of capacity wireless often, and this so-called " last kilometer " has been the last bottleneck of whole telecommunications network development.
For a long time even comprise present stage, the modal method that solves " last kilometer " this bottleneck problem is to adopt Remote Interface Unit, just the subscriber unit in the switch is zoomed out with trunk line, make it near certain crowd of users, reduce subscribers feeder length to greatest extent by certain concentration ratio.This method adopts copper cable in point-to-point PDH (PDH (Pseudo-synchronous Digital Hierarchy)) mode each Remote Interface Unit and switch to be formed a star network usually, but expansion along with the market demand of rural area " conversation of village village ", Remote Interface Unit will get more and more, trunk between switch and the Remote Interface Unit certainly will be also more and more intensive congested, and line cost still can't be able to effective reduction.Simultaneously, existing Remote Interface Unit does not generally integrate power supply, distributing frame, does not have environment centralized supervision equipment yet, can't accomplish unattended operation, and a large amount of introducings of Remote Interface Unit bring great inconvenience for the network operation and maintenance management.In addition, the continuous expansion of telecommunication service has also proposed more and more higher requirement to broadband, the synthesization of communication network, and traditional copper cable has been difficult to satisfy the user to various new business, especially integrates the demand of the integrated service of speech, data and image.Therefore, Remote Interface Unit can't fundamentally solve the bottleneck problem of telecommunications network " last kilometer ".
Nearly 2 years, another kind of solution---multi-service access node has been proposed again " last kilometer " this bottleneck problem.This network is made up of optical network unit ONU and optical line terminal equipment OLT, built-in optical transmission devices such as SDH in optical network unit ONU and optical line terminal equipment OLT, to realize that optical network unit ONU is connected with optical fiber between the optical line terminal equipment OLT, can form the network topology structure of various complexity.Optical network unit ONU generally is placed on the user concentrated area, as residential quarters, commerce and trade sub-district, office block, village, center etc., mainly is responsible for the access of the required business of user; Optical line terminal equipment OLT is the center frame of Access Network, generally is placed in the machine room, and an end links to each other with optical network unit ONU by built-in optical transmission device, and the other end links to each other with switch with the E1 trunk line.Between optical line terminal equipment OLT and switch,, the customer service that optical network unit ONU inserted finally is linked on the public telephone network PSTN by open V5 interface.Access network equipment links to each other with switch by the V5 interface, its network equipment is independent of switch, Access Network also has the network management system of oneself, the maintenance of its corresponding device focuses on the operating maintenance module OAM of optical line terminal equipment OLT, Operation ﹠ Maintenance System on the operating maintenance module OAM needs to link to each other with the local network management center through the Q3 interface, includes local webmaster in by the corresponding protocol conversion.In fact, Access Network is that the service access unit by optical transmission device and optical network unit ONU zooms out the function of exchanger user unit, make service signals such as voice by office exchange through optic fibre extension to the trading estate, residential quarter and remote rural area, but will comprise that the Operation and Maintenance of user's access net system then focuses on the optical line terminal equipment OLT.Owing to adopted the optical transport technology of SDH synchronous digital, access network equipment has powerful and networking capability flexibly, an optical line terminal equipment OLT can connect a plurality of optical network unit ONU, place an optical network unit ONU in the place that the user concentrates, and lay a certain existing optical network unit ONU or the optical line terminal equipment OLT of an optical fiber to Access Network, just can be to switch with user's service access.In addition, access network equipment also is integrated in equipment such as primary power source, secondary power supply, storage battery, distributing frame, environmental monitoring in the optical network unit ONU frame, and carries out centralized monitor on optical line terminal equipment OLT.
After Access Network adopted the above-mentioned network system, the Remote Interface Unit of final function of finishing and switch was similar on the narrowband speech business, provided a kind of efficient ways to solving " last kilometer " problem.But access network equipment is in actual applications, also has many problems, mainly shows:
1. switch and Access Network respectively have the Operation ﹠ Maintenance System of oneself, and the user should safeguard the data of exchanger side, safeguard the data of Access Network side again, and by the data consistent of manually guaranteeing both sides, have increased the complexity of safeguarding;
2. all devices of Access Network is not attached to switch, can't help the Operation ﹠ Maintenance System management of switch, and the Operation ﹠ Maintenance System of oneself is arranged on optical line terminal equipment OLT.If local exchange has a plurality of Switching Modules to have Access Network, and the words of each Switching Module apart from each other, then be distributed on each optical line terminal equipment OLT network management system need by the DDN special line, X.25 or the Q3 interface just can send female office centralized network management, can't accomplish unattended operation truly, this brings great inconvenience to Operation and Maintenance;
3. introducing Access Network not only needs to be used for the optical network unit ONU of access service, also needs to be used to connect the optical line terminal equipment OLT and the background net management system of switch, and equipment is loaded down with trivial details, complicated;
4. in Access Network, the customer call on the optical network unit ONU need pass through this intermediate equipment of optical line terminal equipment OLT, just can finish by the V5 interface between switch and the optical line terminal equipment OLT again.Because the V5 agreement is not very complete, different vendor may be different to the understanding of agreement, and the reliability that makes system that increases of intermediate link and protocol interface is difficult to be guaranteed;
5. in Access Network, also there are many problems in subscriber line test.For the user on the optical network unit ONU, to accuse platform by switch 112 Shens earlier and accept, be transmitted to the 112 Shens announcement platform of Access Network again by the V5 interface, by Access Network the user is tested, and outside can only surveying, in can not surveying, test process is loaded down with trivial details, and fault is difficult for accurately location;
6. optical network unit ONU only provides the interface of service access, itself does not possess any traffic handing capacity, when transmission system breaks down, all of this optical network unit ONU are with not calling out per family, even the user of this optical network unit ONU inside also can't call out mutually, whole optical network unit ONU will be in paralyzed state fully.
As previously mentioned,, all can not solve the problem of " last kilometer " well no matter be Remote Interface Unit or access network equipment, therefore press for and to propose a kind ofly to be similar to Access Network but must to belong to the auxiliary device of switch.
