Abstract

A cross connect physical layer switching system is integrated into a central office and facilitates delivering data services, such as digital subscriber line (DSL) service, to subscribers over a shared data and voice line. The cross connect physical layer switching system may be placed between a splitter and the shared line to allow a remote test unit to be controllably connected to the shared line to permit testing of the shared line by a competitive local exchange carrier (CLEC). By placing the physical layer switching system in the CO, both the CLEC and the incumbent local exchange carrier (ILEC) have full access to the test head (RTU) and full spectrum testing of the line. This allows test access to continue to be done remotely as in an unshared line environment.

Description

Be used on shared circuit, providing the system and method for data and voice service

Technical field

The present invention relates generally to be used for share the system and method for telecommunication line, relate in particular to and be used for providing the voice-and-data service sharing on the circuit, and provide system and method for the voice-and-data service provider the entire spectrum test of sharing circuit.

Background technology

In November, 1999, FCC (FCC) regulation incumbent local exchange carrier (ILEC) must be shared circuit with the local exchange carrier (CLEC) of all competitions.Its objective is the cost-effective solution that is provided for receiving the different pieces of information service for the client.This regulation (FCC 99-355) allows ILEC to keep the low frequency part of telecommunication line, so that voice transfer to be provided, and allows CLEC to use high band, is used for the solution that data insert.

The low frequency part that the circuit HFS that forwards CLEC configuration to is used from ILEC is separated and is needed a splitter.This device has hindered CLEC to finish the voice-and-data test of entire spectrum on local loop.On the other hand, ILEC worries that test that CLEC carries out will disturb the telephone service (POTS) of the routine of ILEC.

In a non-shared circuit environment, each has the entire spectrum test that is linked into circuit separately CLEC and ILEC.Because each ILEC has complete control to its copper cash, therefore ILEC can test the loop for bridge tap, coil and other very important abnormalities concerning reliable analog voice transmission, and CLEC can carry out full test to home loop for very important parameter concerning high speed data transfer.

Yet in the regulation of Line sharing in November, ILEC is required to allow CLEC to share existing line, provides high-speed data service to permit it on the circuit that ILEC provides its POTS to serve.Splitter is exactly a part of equipment that allows to occur this situation.

Splitter makes CLEC to provide high-speed data service to local loop, but stops it that ILEC is provided handled POTS service.Splitter allows ILEC that POTS is provided service, but stops it that high-speed data service is provided.

May not need to provide the POTS business although problem is CLEC, it need finish test on low frequency.The existence of splitter has hindered CLEC to implement the low frequency test, and this test is concerning being to be used for circuit that DSL serves to carry out the Quality Identification be very important.Splitter can be placed in the layout (COLLO) of CLEC or in the central office of ILEC (CO), shown in following block diagram.

For instance, if splitter is placed among the CO of ILEC, CLEC can't implement to guarantee not have on the circuit low frequency test of bridge tap or coil so.Although the existence of tap and coil is not a problem concerning the POTS service of ILEC, then is a subject matter concerning the CLEC that can't test the local loop low frequency part.Effectively carry out in order to share circuit, CLEC must have to the entire spectrum test access of sharing circuit.

Local loop test be CLEC and ILEC all want can long-range execution function.Because splitter in position, if local loop goes wrong, CLEC can only carry out high-frequency test so, and this has just hindered its judgement to root-cause.In order to diagnose a problem, CLEC or ILEC have to send the technical staff to CO, so that inserted a tester before circuit separates.This is very big has increased the extension and the expense of disposing DSL and other high speed business.

Therefore, need a solution, it can make CLEC and ILEC on not filtered home loop, finishes line test via Long-distance Control, and avoids out splitter for test purpose.Concerning CLEC, further need test to be provided the voice call service manner to carry out not disturb ILEC.Also need a kind of can the deployment easily and maintenance solution.

Embodiment

In November, 1999, FCC (FCC) regulation incumbent local exchange carrier (ILEC) must be shared circuit with the local exchange carrier (CLEC) of any competition.Its objective is the cost-effective solution that is provided for receiving the different pieces of information service for the client.This regulation (FCC 99-355) allows ILEC to keep the low frequency part of telecommunication line, so that voice transfer to be provided, and allows CLEC to use high band, is used for the solution that data insert.

This regulation of response FCC, ILEC allows CLEC to close in its facility and establishes data service, for example DSL service.The conventional arrangement of this Line sharing scheme as shown in Figure 1.

With reference to figure 1, ILEC company 100 comprises that one is coupled to switch 100 on the main-frame (MDF) 110 by splitter 108, and it provides traditional voice service for user 116 sharing on the circuit 117.Telephone exchange 101 is called out Client-initiated via a communication network (not shown) and is connected to other phones.Switch also will be connected to subscriber phone 116 from the incoming call of communication network.

ILEC company allows CLEC company 104 to close the data, services of establishing via splitter 108 and shared circuit 117 for user terminal 114 provides.Data, services can be for example Digital Subscriber Line service (DSL), and it is a kind of signaling protocol that transmits wide band digital data on the telephone line of existing two wires.Several DSL versions are arranged in the common application.Asymmetrical Digital Subscriber Line (ADSL) provides the bandwidth bigger than upstream data for downlink data.In addition, ADSL has reserved a part of available channel bandwidth, is used to support traditional analog telephone business (conventional telephone service (POTS)).ADSL mainly towards be house market.The version of another kind of DSL is symmetrical DSL (SDSL).SDSL provides identical bandwidth on up direction and down direction, and the support to POTS is not provided.SDSL is more suitable for service application, for example webserver communication or the like.

In order to provide conventional DSL service from CLEC104 as shown, CLEC104 can dispose the couple in multiplexer (DSLAM) 106 of a Digital Subscriber Line.DSLAM106 is a system that user's DSL connection chain is received IP network.Typically, IP network is the Internet, but also can be any public or exclusive data transmission network.

Share the voice-and-data service in order to provide, splitter 108 is implemented usually as shown in Figure 1.Splitter is connected on DSLAM106, switch 101 and the shared circuit 117.Share circuit 117 and normally share that part that circuit 117 receives from MDF.Splitter 108 is used to the circuit HFS and the employed low frequency part of ILEC that change the CLEC configuration over to are separated.Splitter 108 also is used to stop ILEC to provide high-frequency signal on shared circuit, and stops CLEC to provide low frequency signal on shared circuit.

Another splitter 112 is normally used in user's dwelling house, separating high-frequency data service signal and POTS voice signal, and passes the signal to the data modem unit and the subscriber phone 116 of user terminal 114 respectively.
