In this Order, we address five separate formal complaints filed by paging carriers TSR Wireless, LLC (TSR) and Metrocall, Inc. (Metrocall) (hereinafter “Complainants” or “paging carriers”) against local exchange carriers (LECs) Pacific Bell Telephone Company (Pacific Bell), U S West Communications, Inc. (U S West), GTE Telephone Operations (GTE), and Southwestern Bell Telephone Company (SWBT) (collectively “Defendants”). The paging carriers allege that the LECs improperly imposed charges for facilities used to deliver LEC- originated traffic and for Direct Inward Dialing (DID) numbers in violation of sections 201(b) and 251(b)(5) of the Communications Act of 1934, as amended,1 and the Commission’s rules promulgated thereunder. We find that, pursuant to the Commission’s rules and orders, LECs may not charge paging carriers for delivery of LEC-originated traffic. Consequently, Defendants may not impose upon Complainants charges for facilities used to deliver LEC-originated traffic to Complainants. In addition, we conclude that Defendants may not impose non-cost-based charges upon Complainants solely for the use of numbers. We further conclude that section 51.703(b) of the Commission’s rules does not prohibit LECs from charging, in certain instances, for “wide area calling” or similar services where a terminating carrier agrees to compensate the LEC for toll charges that would otherwise have been paid by the originating carrier’s customer. -

Communications, Transportation and Phases of the Industrial Revolution MJ Peterson
Roots of Interconnection: Communications, Transportation and Phases of the Industrial Revolution MJ Peterson International Dimensions of Ethics Education in Science and Engineering Background Reading Version 1; February 2008 Transnational ethical conflicts are more frequent in the contemporary world and because of the greater interconnection among societies. Though scientists and engineers have maintained active contact with colleagues in other countries for centuries, until recent decades such contacts were limited to periods of study at a foreign university, occasional collaboration in labs or on projects, and exchange of research results through publication or presentation at conferences. As societies became more interconnected, the patterns of joint activity deepened. At the same time, the impacts of science and engineering were felt more deeply in society as the connections between basic science on one side and applied science, technology, and engineering of human-made structures became stronger. Two sets of technological changes increased the possibilities for interconnection between societies by increasing the speed of and broadening access to communications and transportation. The changes in communication took hold more quickly, but both were important to increasing the possibility for interaction among members of different societies. With invention of the telegraph in the 1840s messages could travel from point-to-point at the speed of shifting electrons rather than of galloping horses or relays of visual signals from tower to tower. Basic transmission time between Paris and London went from days (horses) or hours (visual relay) to minutes. However, the need to receive the messages in a special telegraph office, copy the text onto paper, and then either deliver the paper to the recipient or have the recipient come by to pick it up meant that total message time was longer for anyone who did not have a telegraph office on-site. -
Overview of Project Scheduling Following the Definition of Project Activities, the Activities Are Associated with Time to Create a Project Schedule
Project Management Planning Development of a Project Schedule Initial Release 1.0 Date: January 1997 Overview of Project Scheduling Following the definition of project activities, the activities are associated with time to create a project schedule. The project schedule provides a graphical representation of predicted tasks, milestones, dependencies, resource requirements, task duration, and deadlines. The project’s master schedule interrelates all tasks on a common time scale. The project schedule should be detailed enough to show each WBS task to be performed, the name of the person responsible for completing the task, the start and end date of each task, and the expected duration of the task. Like the development of each of the project plan components, developing a schedule is an iterative process. Milestones may suggest additional tasks, tasks may require additional resources, and task completion may be measured by additional milestones. For large, complex projects, detailed sub-schedules may be required to show an adequate level of detail for each task. During the life of the project, actual progress is frequently compared with the original schedule. This allows for evaluation of development activities. The accuracy of the planning process can also be assessed. Basic efforts associated with developing a project schedule include the following: • Define the type of schedule • Define precise and measurable milestones • Estimate task duration • Define priorities • Define the critical path • Document assumptions • Identify risks • Review results Define the Type of Schedule The type of schedule associated with a project relates to the complexity of the implementation. For large, complex projects with a multitude of interrelated tasks, a PERT chart (or activity network) may be used. -
Oversight of the Federal Communications Commission” Senate Committee on Commerce, Science, and Transportation
Chairman John Thune Written Questions for the Record to Commissioner Ajit Pai “Oversight of the Federal Communications Commission” Senate Committee on Commerce, Science, and Transportation Question 1: What are your views on the interconnection provisions in the Open Internet Order and the record on which the FCC based such provisions? Answer: The Notice of Proposed Rulemaking (NPRM) discussed IP interconnection in a single paragraph, tentatively concluding that the FCC should maintain the previous restrained approach, so that the Part 8 “Open Internet” rules would not apply “to the exchange of traffic between networks, whether peering, paid peering, content delivery network (CDN) connection, or any other form of inter-network transmission of data, as well as provider-owned facilities that are dedicated solely to such interconnection.” Nevertheless, the Open Internet Order subjected IP interconnection arrangements to sections 201 and 202 of the Communications Act, arrogating to the FCC the power to order an Internet service provider “to establish physical connections with other carriers, to establish through routes and charges applicable thereto . and to establish and provide facilities and regulations for operating such through routes.” In other words, the Open Internet Order adopted an unprecedented approach radically different from what the NPRM proposed. The record is hardly adequate to justify such a decision. Indeed, the best evidence in the record suggests the free market for interconnection has been an unmitigated success, with transit rates falling 99% over the last decade. In short, that decision was both unwise and unlawful. Question 2: The FCC and state utility commissioners long ago recognized that, if utility-style regulation applies to Internet access service, “it would be difficult to devise a sustainable rationale under which all . -

Scheduling: Introduction
7 Scheduling: Introduction By now low-level mechanisms of running processes (e.g., context switch- ing) should be clear; if they are not, go back a chapter or two, and read the description of how that stuff works again. However, we have yet to un- derstand the high-level policies that an OS scheduler employs. We will now do just that, presenting a series of scheduling policies (sometimes called disciplines) that various smart and hard-working people have de- veloped over the years. The origins of scheduling, in fact, predate computer systems; early approaches were taken from the field of operations management and ap- plied to computers. This reality should be no surprise: assembly lines and many other human endeavors also require scheduling, and many of the same concerns exist therein, including a laser-like desire for efficiency. And thus, our problem: THE CRUX: HOW TO DEVELOP SCHEDULING POLICY How should we develop a basic framework for thinking about scheduling policies? What are the key assumptions? What metrics are important? What basic approaches have been used in the earliest of com- puter systems? 7.1 Workload Assumptions Before getting into the range of possible policies, let us first make a number of simplifying assumptions about the processes running in the system, sometimes collectively called the workload. Determining the workload is a critical part of building policies, and the more you know about workload, the more fine-tuned your policy can be. The workload assumptions we make here are mostly unrealistic, but that is alright (for now), because we will relax them as we go, and even- tually develop what we will refer to as .. -
