Introduce

In November, 1999, FCC (FCC) stipulates that traditional LEC (ILEC) must share circuit with any competition LEC (CLEC).Its objective is the solution that is provided for receiving the cost efficient of the data service that adapts to individual difference for the user.The low frequency part that this rule (FCC99-355) allows ILEC to keep telecommunication line provides voice transfer and CLEC that high band is used for the data access solution.

Respond this FCC rule, ILEC carries out the hosting data service by allowing CLEC in their equipment, make response such as the DSL business.In the trifle of following by name " Line sharing ", illustrated and described with reference to these and be used for sharing between CLEC and ILEC the conventional apparatus (Fig. 1) of circuit and the discussion of innovative device (Fig. 1-4).Fig. 5-18 describes in detail and is used for being implemented in one or more different central office location, the cross-connect switch of the concentrated Long-distance Control of one or more cross-connect switchs of realizing on local and/or wide area network and the embodiment of technology.

CLEC supplies to CLEC

Figure 19 describes the embodiment of CLEC of the present invention to the CLEC supply.With reference to Figure 19, ILEC central office 1900 comprises the CLEC device 1930 of a plurality of assembly.Device 1930 comprises a plurality of ports that are used to provide business.Usually, device 1930 is exchange and/or route device.According to one embodiment of present invention, device 1930 is digital subscriber line access multiplex (DSLAM).But this DSLAM ADSL, SDSL, HDSL, VoDSL, SHDSL, VDSL or other types.

As shown in the figure, central office 1900 comprises the main frame (main distribution frame) 1955 of the circuit that is coupled to the remote user device shown in being used to supply with.For example, plain old telephone service (POTS) line is coupled to phone 1910 with the central office; The SDLS line is coupled to PC 1915 with central office 1900; The POTS/ADSL line is coupled to the central office phone 1920 and PC 1925 on common lines.

With reference to Figure 19, ILEC and each CLEC have a plurality of ports that are coupled to cross-connect switch 1905.Under the control of the remote client 1965 that is connected to cross-connect switch 1905, through local or wide area network 1960, cross-connect switch 1905 forms interconnection.This cross-connect switch can produce several dissimilar connections so that various types of CLEC to the coupling of CLEC (and CLEC coupling) to the coupling of ILEC and CLEC and ILEC to the user.The may command interconnection is so that the internal loopback that forms as shown in figure 19 connects (loop back connection) 1940.This can be used to the port interconnection of CLEC 1930 is arrived the another port of different CLEC 1930.May command cross-connect switch 1905 connects 1950 to form external loop, so that the port of CLEC 1930 is connected to the another port of different CLEC 1930.In addition, can use cross-connect switch 1905 to form being connected of CLEC 1935 and CLEC 1930 ports and 1955 of MDF, MDF1955 is coupled to these ports on the subscriber's line subsequently.

When on a pair of CLEC is commencing business, reaching an agreement, CLEC can determine the to interconnect port of their devices 1930 separately.This interconnection can allow a CLEC to expand its DSL business and provide by for example renting capacity from another CLEC.The whole new business that this capacity of renting can represent to be used for the tenant maybe can be represented the expansion of existing business.Also can carry out interconnection reflects by a CLEC from another purchase or the reciprocal exchange of business.Can realize the interconnection device of various other types so that CLEC provides to the CLEC business, comprise test.

Figure 20 describes the network diagram of shaking the prosecutor face of supplying the interconnection configuration of the above with reference to CLEC shown in Figure 19 to CLEC.With reference to Figure 20, network operation center (NOC) is the central equipment that comprises CMS client computer 2025, CMS database server 2030 and cm agent server 2040.Can use these network element in the NOC usually to provide equipment so that remotely create of the interconnection of one or more particular ports of a CLEC to one or more particular ports of another CLEC with client terminal 2025 reciprocations as ILEC employee.This solution is to propose at the long-range supply between CLEC assembly chamber (collocation closet), recalls general introduction in the order according to the assembly in August 8 calendar year 2001, and this responsibility belongs to ILEC now.The NHC system scheme is run after fame with ControlPoint and is sold and be cited forward from this point.

ControlPoint comprises three major parts, " CMS client/professional device " management software platform, " CMS is long-range " controller and " ControlPoint " cross-connect matrix.This system allows ILEC supply operator to control through CMS Client gui software a long way off, controls cross-connect matrix from position, network operation center, center (NOC).Therefore, the user can be long-range provide circuit and needn't provide professional to the doorstep, and the technician will need drive long-range CO and/or the assembly website is physically carried out interconnection required on the website in addition thus.CMS is long-range and the ControlPoint interconnection is physically located in each desired CO of telemanagement and the assembly chamber is located.

Figure below is described NHC ControlPoint system.CMS client computer 2028 is used for issue an order by ILEC.Typically, according to the quantity of the operator that bears supply, such CMS client computer of surpassing will be arranged.These orders are the specific commands that one or more ports are connected to one or more other ports.But CMS database server of client computer 2025 accesses, this server are used on the basis of port one by one, for client computer 2025 provides current configuration information on the relevant cross-connect switch.Client computer can show this information to the user of client computer 2025 with figure.Then, by handling current port arrangement, the user can make the supply change.Then, this supply change is issued as order by client computer 2025.

On LAN 2020, use agreement sends to cm agent server 2040 with these orders.A cm agent server 2040 can be handled the long-range ControlPoint interconnection combination of a plurality of CMS/.The cm agent server organization is from the supply request of each CMS client computer and on LAN/WAN, by using SNMP, TCP or similarly agreement and suitable CMS long-range (remote) communicate.This CMS is long-range can be connected to ControlPoint interconnection (being depicted as 3 interconnections of series coupled and can being connected to single CMS long-range) in turn and the order that has received on LAN/WAN is sent to matrix.Alternatively, the long-range cross connect switch matrix that is parallel to of CMS.System protocol is designed to communicate by letter back and forth, so as to guarantee data integrity and keep the actual disposition of cross-connect switch and the configuration shown in the database 2030 between synchronously.

After completing successfully connection, CMS long-range 2015 returns to the cm agent server with affirmation, and then, this cm agent server sends to database server 2030 with this affirmation and reflects this new connection so that upgrade this database.In this way, the current configuration of database reflection cross-connect switch.As shown in the figure, NOC can be arranged in the single position that is used for controlling a plurality of different central offices.But the geographical distribution client machine system also is connected to database 2030 and acting server 2040 by LAN/WAN 2020.

Figure 21 describes via remote control terminal and forms cross-coupled method between the CLEC device automatically.This method comprises from the CLEC reception and being used for the port of a device and the request of the another port interconnection of the device that belongs to another CLEC.This device is DSLAM device or other exchanges or route device.CLEC can communicate that request to the personnel at ILEC place in any way.Automatically collect this request and for example with it from being used for providing the information system of business to be sent to the average information system of ILEC personnel, ILEC client computer 2025 or ILEC via electronic information at CLEC.

In step 2110, the personnel of ILEC are defined into the business change request of client computer 2025.This is normally undertaken by the personnel of client machine system 2025 and the information in the database server 2030 of being stored in, and reciprocation finishes.The information in the database of being stored in can represent that the pattern description of current configuration of this switch or other represent easily.Then, the user of system 2025 can be used for defining business change with system interaction.But this business change CLEC connects to MDF to MDF connection or ILEC to ILEC connection, CLEC to CLEC connection, CLEC.

In step 2120, client is used to form interconnection to the interconnection issue an order.Can this order be sent to acting server by LAN/WAN 2020, this acting server is handled successively and that this order is transmitted to CMS is long-range 2015, handles being used for.Then, in step 2130, interconnection responds this order and forms connection.In step 2140, provide professional according to interconnection CLEC port.

As described below, the testing apparatus of mutual benefit easy to use by interconnection can be by a CLEC and the shared circuit from the central office of ILEC.This common lines also can be used to provide shared service at a CLEC between the coupling business of CLEC and POTS ILEC business.

Line sharing

With reference to figure 1, ILEC company 100 comprises the switch 101 that is coupled to MDF 110 by separator (splitter) 108, and it provides traditional speech business to user 116 on shared circuit 117.Telephone exchange 101 will be called out through the communication network (not shown) by Client-initiated and be connected to another phone.This switch also will be connected to subscriber phone 116 from the incoming call of communication network.

ILEC company allows CLEC company 104 to provide the hosting data service through separator 108 and shared circuit 117 to user terminal 114.This data service is digital subscriber line business (DSL) for example, and this business is a signaling protocol that is used to transport wide band digital data on existing two-wire telephone wire.Normally used have the DSL. asymmetric D SL (ADSL) of several versions to provide bigger bandwidth to downstream data comparison upstream data.In addition, ADSL reserved part available channel bandwidth is used to support traditional analog telephone business (plain old telephone service (POTS)).ADSL is primarily aimed at family market (residentialmarket).The DSL of another kind of version is symmetrical DSL (SDSL).SDSL provides equal bandwidth in the upstream and downstream direction, and POTS is not provided support.SDSL is more suitable for using in commerce, such as webserver communication or the like.

As shown in the figure, for traditional DSL business, the configurable digital subscriber line access of CLEC104 multiplexer (DSLAM) 106 are provided from CLEC 104.DSLAM 106 is the systems that user DSL connection chain received IP network.Usually, IP network is Internet, but also any public or special-purpose data transmission network.
