In local telephone networks, a loop management system (LMS) is a kind or a part of network management system intended to maximize local loop control. Sometimes it is referred to as local loop management (LLM) or copper loop management (CLM).
Although local loop unbundling is a standard process for an incumbent (ILEC), issues remain to be solved in the local loop management process. For a CLEC which borrows lines from ILEC for DSL services provisioning process, a local loop is the most critical (and the most weak) point because of reduced management of this vital part of the network.
During the provisioning process, a CLEC can request from its serving ILEC, a new cross-connect. By agreement ILEC must fulfill this request but it's almost impossible to immediately learn a local loop's quality or monitor its activity in real time. Such steps are sometimes mandatory for loop pretesting and qualification in order to validate its good (or bad) condition. Furthermore, testing and validation steps are vital in troubleshooting process.
LMS, sometimes implemented as a part of a major network management system, views the local loop as an active network element. It speeds pre-qualification and reduces fault correction time.
A complete LMS has software and hardware components. The latter is usually a switch fabric connected both to all required lines and line equipment at either side of a line. The functionality is similar to one performed by a main distribution frame or any other distribution frame, so sometimes is referred to as automated main distribution frame. A software component implies implementing management operations.
In digital computers, an interrupt is a request for the processor to interrupt currently executing code, so that the event can be processed in a timely manner. If the request is accepted, the processor will suspend its current activities, save its state, and execute a function called an interrupt handler to deal with the event. This interruption is often temporary, allowing the software to resume normal activities after the interrupt handler finishes, although the interrupt could instead indicate a fatal error.
Local loop unbundling is the regulatory process of allowing multiple telecommunications operators to use connections from the telephone exchange to the customer's premises. The physical wire connection between the local exchange and the customer is known as a "local loop", and is owned by the incumbent local exchange carrier. To increase competition, other providers are granted unbundled access.
Digital subscriber line is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
The T-carrier is a member of the series of carrier systems developed by AT&T Bell Laboratories for digital transmission of multiplexed telephone calls.
In computer science, inter-process communication or interprocess communication (IPC) refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.
The Telecommunications Act of 1996 is a United States federal law enacted by the 104th United States Congress on January 3, 1996, and signed into law on February 8, 1996, by President Bill Clinton. It primarily amended Chapter 5 of Title 47 of the United States Code.
A competitive local exchange carrier (CLEC), in the United States and Canada, is a telecommunications provider company competing with other, already established carriers, generally the incumbent local exchange carrier (ILEC).
In software engineering, the terms frontend and backend refer to the separation of concerns between the presentation layer (frontend), and the data access layer (backend) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself.
Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.
A laboratory information management system (LIMS), sometimes referred to as a laboratory information system (LIS) or laboratory management system (LMS), is a software-based solution with features that support a modern laboratory's operations. Key features include—but are not limited to—workflow and data tracking support, flexible architecture, and data exchange interfaces, which fully "support its use in regulated environments". The features and uses of a LIMS have evolved over the years from simple sample tracking to an enterprise resource planning tool that manages multiple aspects of laboratory informatics.
An incumbent local exchange carrier (ILEC) is a local telephone company which held the regional monopoly on landline service before the market was opened to competitive local exchange carriers, or the corporate successor of such a firm.
Within quality management systems (QMS) and information technology (IT) systems, change control is a process—either formal or informal—used to ensure that changes to a product or system are introduced in a controlled and coordinated manner. It reduces the possibility that unnecessary changes will be introduced to a system without forethought, introducing faults into the system or undoing changes made by other users of software. The goals of a change control procedure usually include minimal disruption to services, reduction in back-out activities, and cost-effective utilization of resources involved in implementing change. According to the Project Management Institute, change control is a "process whereby modifications to documents, deliverables, or baselines associated with the project are identified, documented, approved, or rejected."
The V-model is a graphical representation of a systems development lifecycle. It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
Telecommunications mediation is a process that converts call data to pre-defined layouts that can be imported by a specific billing system or other OSS applications.
Validation is the process of establishing documentary evidence demonstrating that a procedure, process, or activity carried out in testing and then production maintains the desired level of compliance at all stages. In the pharmaceutical industry, it is very important that in addition to final testing and compliance of products, it is also assured that the process will consistently produce the expected results. The desired results are established in terms of specifications for outcome of the process. Qualification of systems and equipment is therefore a part of the process of validation. Validation is a requirement of food, drug and pharmaceutical regulating agencies such as the US FDA and their good manufacturing practices guidelines. Since a wide variety of procedures, processes, and activities need to be validated, the field of validation is divided into a number of subsections including the following:
In computer programming, flow-based programming (FBP) is a programming paradigm that defines applications as networks of "black box" processes, which exchange data across predefined connections by message passing, where the connections are specified externally to the processes. These black box processes can be reconnected endlessly to form different applications without having to be changed internally. FBP is thus naturally component-oriented.
Performance engineering encompasses the techniques applied during a systems development life cycle to ensure the non-functional requirements for performance will be met. It may be alternatively referred to as systems performance engineering within systems engineering, and software performance engineering or application performance engineering within software engineering.
Automated main distribution frame (AMDF),, a technology to provide connectivity between subscriber – and office equipment lines in a telephone exchange main distribution frame (MDF).
USTAv.FCC is the 2004 court case in which the Washington, D.C., Circuit Court of Appeals vacated the Federal Communications Commission's Triennial Review Order (TRO). The court's decision is based on the Telecommunications Act of 1996 section 251 which defines unbundled network elements (UNEs) for incumbent local exchange carriers and competitive local exchange carriers.
Total element long-run incremental cost (TELRIC) is a calculation method that the United States Federal Communications Commission (FCC) requires incumbent local exchange carriers (ILECs) to use to charge competitive local exchange carriers (CLECs) for interconnection and colocation, effectively imposing a price ceiling. A variant of long-run incremental cost (LRIC), it "measures the forward-looking incremental cost of adding or subtracting a network element" from a hypothetical system. This allows the incumbent to recover a share of the fair value of their inputs in the long run.
