Description
Technical field
The utility model relates to a kind of test line capture module equipment that business renews function that has, and when providing automatic testing service for the fixed network operator, has guaranteed the normal operation of the subscriber's line that switching equipment connected effectively, belongs to communication technical field.
Background technology
At present, the traffic growth of domestic fixed-line telephone network is still very swift and violent, and especially novel ADSL digital service, fixed telephone subscriber's sum are developing to 400,000,000 families, so the service quality of operation maintenance obtains the generally attention of vast operator.Along with the rapid rising of line clear test job amount and the line upkeep Shen announcement amount of accepting, use full-automatic integrated test system and realize that operation maintenance becomes an inevitable choice.Full-automatic integrated test system by testing the interior and exterior lines that line capture module is grabbed out, is carried out sectionalization test to local side apparatus, subscriber's line and ustomer premises access equipment as shown in Figure 1, and therefore, the test line capture module then is the necessary condition that realizes full-automatic integration test.
Test line capture module in the full-automatic integrated test system structurally divides three levels: the line capture module equipment in the exchange transmission equipment in line capture module, the local side test macro, the line capture module circuit in the test cell.
In the exchange transmission equipment, the test line capture module is arranged on exchange transmission equipment user's plate and the DSLAM separator board, every exchange transmission equipment or a pair of test bus of DSLAM equipment output two-wire system, perhaps four-wire system a pair of test bus interior lines and a pair of test bus outside line.Grab the line order by sending out, interior lines or the outside line of any one user in the equipment can be caught the test bus interface, realize that test connects to equipment.
In the local side test macro, test line capture module equipment is used for the test bus of many exchange transmission equipments and polytype exchange transmission equipment is restrained, and realizes concentrating test and management.
In test cell, test line capture module circuit is mainly used in continuing of various different test functions, has also considered the needs that the input test bus is restrained simultaneously.In less end office (EO) of some exchange transmission equipment kind, platform number such as module office etc., test macro does not need configuration testing line capture module equipment, just can finish the test jointing function with the test line capture module circuit of test cell inside.
In the operation maintenance net that the fixed network operator sets up with autorun, in order to guarantee the service quality of fixed-line telephone network operation maintenance, full-automatic integrated test system is after the exchange transmission equipment sends test command, to judge whether decision carries out next step test again to the running status of subscriber's line.The exchange transmission equipment receive grab the line order after the state information of this circuit of loopback, if line be busy, test macro will determine whether toll breakdown test.But the exchange transmission equipment that the part four-wire system is grabbed line is not automatically considered the running status of tested circuit, after equipment receives that the line order is grabbed in test, when line state information is provided, circuit is disconnected and catches on the test port.This unauthorized toll breakdown the operation tend to unexpected interrupting service, influence the service quality of operator.
Operation maintenance in the past mainly is emulation testing, and line test precision and fault location precision are all very low, and the subscriber complaint handling process is also very simple.After the full-automatic integrated test system that has adopted the multi-process that exchanges transmission equipment based on the multi-modulation scheme of grabbing line automatically, O﹠M service quality there has been higher requirement, need test line capture module equipment have the function that the subscriber's line business renews.
Summary of the invention
The purpose of this utility model provides a kind of switch of avoiding and accepts to test the business of interrupting subscriber's line when grabbing the line order suddenly, guarantees the test line capture module equipment that business renews function that has of operator's service quality.For realizing above purpose, the technical solution of the utility model provides a kind of test line capture module equipment that business renews function that has, comprise that exchanging the transmission equipment interior lines grabs line interface, line interface is grabbed in the outside line of exchange transmission equipment, test cell Internal Line Test interface, test cell Loop test interface and relay array, it is characterized in that, be connected separately in the test line capture module circuit of application with test cell at exchange transmission equipment test interface, be provided with that line relay RL101 is grabbed in interior lines and line relay RL102 is grabbed in outside line, the normal-closed end that line relay RL101 is grabbed in interior lines and outside line grab that the normal-closed end RL102 of line relay is corresponding to be connected a business and to renew connection line, form the single-stage business and renew connecting circuit, the interior lines of exchange transmission equipment are by the common port of relay R L101, normal-closed end to relay R L101, arrive the normal-closed end of relay R L102 again, by the outside line of the common port of relay R L102, realize that the business of subscriber's line renews function again to the exchange transmission equipment.
In the test line capture module equipment of multiple-input and multiple-output, it is characterized in that, adopt the multi-stage cascade business to renew connection, the input port of matrix connects exchange transmission equipment A respectively, exchange transmission equipment B, ... line interface is grabbed in the interior and exterior lines test of exchange transmission equipment n, the output port of matrix connects test cell α respectively, test cell β, ... the interior and exterior lines test input interface of test cell , it is characterized in that, grab the normal-closed end of the terminal relay of cascade of line relay link in the interior lines of each exchange transmission equipment correspondence, a business of the corresponding connection of normal-closed end of grabbing the terminal relay of cascade of line relay link with the outside line of matrix renews connection line, and employing multi-stage cascade business renews that the realization business renews function under the connecting circuit state that all relays all discharge in two links.
The utility model is grabbed the interior lines of each exchange transmission equipment correspondence the normal-closed end of the terminal relay of cascade of line relay link, a business of the corresponding connection of normal-closed end of grabbing the terminal relay of cascade of line relay link with the outside line of matrix renews connection line, and the realization business renews function under the state that all relays all discharge in two links.After equipment receives that the line order is grabbed in test, this unauthorized toll breakdown operation can interrupting service yet, guarantee the service quality of operator.
The utility model has the advantages that when avoiding switch to accept test grabs the line order and interrupt customer service suddenly, guarantee operator's service quality.
