Description:
[0001]    This application claims benefit of U.S. Provisional Application No. 60/219,194, filed Jul. 19, 2000, which is hereby incorporated by reference. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The present invention relates to systems and methods for mapping connections from a port on a switching card to a pin on a frame at a central office of a telecommunications system, or for mapping a pin on a frame to an outside plant feeder.  
           [0004]    2. Related Art  
           [0005]    To provide services to their customers, telecommunications companies (telcos) maintain a system of wire and fiberoptic land lines connecting their central offices (COs), at which switching cards are located, with their subscribers. This is true whether the service is telephone service, broadband Internet access, such as, for example, DSL or optical cable, or other broadband services, such as, for example, video-conferencing and land line delivery of television programming.  
           [0006]    The path between a subscriber&#39;s address and a CO includes several stages, such as a drop connecting the address to a serving terminal; a distribution connecting the serving terminal to a cross-box; and a feeder connecting the cross-box with the CO. The feeder enters the CO by connecting to a pin on a frame, which is connected to a port on a switching card by a jumper, either directly or through one or more intermediate pins and jumpers. The frame itself is a physical structure located within the CO, laid out in a matrix of blocks, each of which includes a matrix of pins.  
           [0007]    A pin in a frame is identified by a coordinate system based upon the physical location of the pin on the frame. However, due to the enormous number of frames, and the number of pins on each frame, the mapping of ports to pins on a frame and pins on the frame to feeders has up to now been a relatively complex undertaking, one that must be performed by specially trained personnel, assisted by specialized software running on a mainframe computer. Moreover, because such existing computer systems are text-based, they do not offer the user the ability to readily visualize the frame in relation to the incoming and outgoing lines, and are therefore not optimal for the mapping functions to which they are directed.  
           [0008]    Thus, the need exists for a system that allows a user to visualize the frame and lines connected thereto more easily, thus making mapping easier. There also is a need for a system that can access a database of a telco&#39;s resources to assist in controlling the growth and maintenance of frames in CO&#39;s.  
         SUMMARY OF THE INVENTION  
         [0009]    In consideration of the above, to facilitate mapping from a port on a switching card to a pin on a frame at the central office, or mapping from a pin on a frame to an outside plant feeder, there is provided a graphical user interface running on a client computer or workstation that is operable to contact and communicate with a server that can access a database containing data relating to the resources of a telecommunications system. With the data, the graphical user interface of the present invention can present a graphical representation of frames, down to the pin levels, residing in the various central offices of the telecommunications system and allow for examination and modification of such frames.  
           [0010]    In accordance with one aspect of the present invention, there is provided a method of presenting to a user a visual representation of a frame resident at a central office of a telecommunications system. The method comprises: accessing a database including data as to a current condition of the frame; displaying, based on the accessed data, a graphical representation of the frame, the graphical representation including a visual indication of the current condition of the frame; and allowing a user to interface with the graphical representation to effect a mapping between the frame and telecommunications lines leading to and from the frame.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0028]    [0028]FIG. 1 illustrates an exemplary central office (CO) layout for a telephone company (telco). The figure shows the various types of equipment that may reside in, or interface with, a CO. Not every CO will have, or interface with, every type of equipment shown in the figure.  
         [0029]    In the illustrated CO, digital switch  200  is connected by a DS 1  data voice channel to digital signal cross-connect (DSX- 1 )  230 , as is digital access and cross connects (DACS)  210 . An M 13  Mux is connected to the digital signal cross-connect  230 , by DS 1 , and to the digital signal cross-connect (DSX- 3 )  235 , by DS 3  data voice channel (coaxial cable). Another DS 3  cable connects the digital signal cross-connect (DSX- 3 )  235  to fiber optic system  240  and the fiber optic system is in turn connected by fiber jumpers to light guide cross connect (LGX)  245 . Connections from that point are by OSP fiber cable.  
         [0030]    Digital signal cross-connect (DSX- 1 )  230  connects by DS 1  to integrated services digital network (ISDN)  250 , which is in turn connected, by 2B+D basic rate interface (BRI) to the main distribution frame (MDF)  275 . Digital signal cross-connect (DSX- 1 )  230  also connects by DS 1  to a fourth generation channel bank (D 4  channel bank)  255 , which is in turn connected, by VF signal, with the MDF  275 . Digital signal cross-connect (DSX- 1 )  230  also is connected to very high speed digital subscriber loop  260 , which is in turn connected, by HDSL DS 1 , to the MDF  275 . Digital signal cross-connect (DSX- 1 )  230  also connects, by DS 1  to DS 1  line termination shelf  270 , which is in turn connected, by span powered DS 1 , to the MDF  275 .  
         [0031]    An MDF in a typical CO provides pair protection by including protectors, which terminate the outside plant pair and provide lightning protection to the pair, and blocks, which terminate the lines from the equipment and are wired out to a cross connect cabinet. FIG. 2 illustrates the protector  4  and terminal block  6  of a typical MDF, in relation to the cable pair  3 , the line equipment jumper  5  and the equipment cabling  7 .  
         [0032]    The organization and layout of telecommunication frames is rather complex, in no small part because of the number of pins on each of a very large number of frames. To bring some order to this complexity, a set of identifying conventions have been developed. These conventions allow a person to identify a particular frame at a particular location, as well as a particular portion of that frame. At the highest level, each frame may be referred to by identifying its physical location, e.g., at which CO it resides. Since there may be more than one frame at any given location, each frame is further identified by a number.  
         [0033]    In addition to location and number, frames are differentiated by type. Specifically, a frame may be classified as being either a main distribution frame (MDF) or a tie frame (TIE). An MDF connects lines coming from outside or going to outside of the CO, while a TIE frame provides jumpers internal to the CO. An MDF may be either single sided or double sided. A TIE frame is always single sided.  
         [0034]    A single sided frame, whether an MDF or a TIE frame, is organized by sub-components known as modules. Each module contains hardware known as shelves; each shelf contains hardware referred to as blocks. The modules, shelves and blocks are usually identified by numbers. A combination of these numbers, known as a “triple” (module number, shelf number and block number) uniquely identifies any particular block on a frame and acts as the block&#39;s frame coordinates.  
         [0035]    A double sided frame has two sides. One side is called the “horizontal” side. The other side is called the “vertical” side. Each side of a double sided frame is divided into constituent blocks. A block, on either the horizontal side or the vertical side of the double sided frame, is identified by its vertical coordinate and its horizontal coordinate. The terms vertical and horizontal in this context should not be confused with the use of those terms in the context of vertical and horizontal sides.  
         [0036]    A block on a double sided frame can be uniquely identified by its “triple” (side, vertical, horizontal). This triple functions as a block&#39;s frame coordinates. By convention, verticals are identified by a number and horizontals by an alpha character.  
         [0037]    A frame break table defines the position and characteristics of each break in the frame, a break being a physical gap between two modules (verticals) of a frame. A frame may have zero or more frame breaks.  
         [0038]    [0038]FIG. 3 shows an exemplary main distribution frame (MDF), which provides pair protection and has a two sided frame horizontal side having line blocks and a vertical side having cable protectors. In particular, the figure shows a single sided frame. Reference numeral  300  indicates a shelf. Other shelves are situated above and below the referenced shelf  300 . Reference numeral  310  indicates an example of a block, with other blocks situated to the left and right of the referenced block  310 . An example of a module is indicated by reference numeral  320 . Note that the module has several blocks. FIG. 4 shows a main distribution frame vertical side, showing the protectors for the termination of cable pairs in greater detail.  
         [0039]    [0039]FIG. 5 shows a main distribution frame cable pair protector, which provides a hundred pair termination of cable pairs and lightning protection. FIG. 6 shows a main distribution frame cable pair protector, showing jumpers to the line circuit of the telephone switch. In particular, the figure shows a double sided frame vertical side. FIG. 7 shows a main frame horizontal side, having blocks, such as the one indicated by reference numeral  400 , for termination of line circuits. FIG. 8 shows blocks on an MDF. In particular, the figure shows a double sided frame horizontal side. An exemplary shelf is indicated by reference numeral  500 . An exemplary block is indicated by reference numeral  510 .  
         [0040]    According to a preferred embodiment of the present invention, a graphical user interface (GUI) is provided to allow a user to map connections from a port on a switching card inside a CO to a pin on a frame, and to map a pin on a frame to an outside plant feeder. The software generating the GUI provides this functionality by presenting the user with a series of windows, including a graphical representation of any given frame within the telecommunications system. In accordance with one preferred embodiment of the present invention, accessing a given block of the frame, by clicking-on the graphical representation of that block, displays, among other things, information regarding how many pins are contained in the block, how many are in use and how many are available. A user may map ports to pins, pins to other pins, or pins to feeders by accessing a visual representation of a block and indicating, by interaction with the graphical user interface, that he wishes to map a port or feeder to it. The software will select the specific pin automatically, if one is available, by referencing a database of telco assets.  
         [0041]    The graphical user interface that is used to implement this visualization is formed by software running on a user&#39;s computer or workstation. The software is operable to access a database of information as to the assets of the telco, including current information as to the current usage and availability of pins of each frame in every CO.  
         [0042]    The software is preferably implemented to run as a browser on a client computer in a system having a client/server architecture. In such a system, the server runs on a site on a network, such as a site on the World Wide Web. The client browser is operable to request information from the server site. Preferably, the server has access, e.g., via well-known Common Gateway Interface (CGI) techniques, to a database of the hardware assets of the telco. The client/server architecture advantageously allows many different users to run the GUI software to access the server and the database simultaneously.  
         [0043]    As will be shown, the GUI of the present invention presents the frame data in an easy to visualize format, making it simple for a user to keep track of frame pin assignments and oversee the growth of the frame.  
         [0044]    [0044]FIG. 9 shows an exemplary frame browser window in accordance with a preferred embodiment of the present invention. The frame browser window lets the user view a list of wire center locations (i.e., CO&#39;s) and the frames associated with each. Clicking on the wire center folder lets the user see the location list. Clicking on a location lets the user see any frames that are at the location. For example, in the figure, the locations for wire center SW 77738  are listed and the folder for location GRAPEVINE has been opened to show frame MAIN. Highlighting a frame in the list changes the function buttons displayed in the window. Function buttons let the user access other windows that can be used to perform frame administration tasks.  
         [0045]    The frame browser having the GUI of the present invention preferably is included as a menu option in a larger on-line transaction processing system of the telco, but may run as a standalone program on a client with access to a network server as described above, without departing from the spirit of the present invention.
