In telecommunications, a customer service unit (CSU) is a device that provides an accessing arrangement at a user location to either switched or point-to-point, data-conditioned circuits at a specifically established data signaling rate.
A CSU provides local loop equalization, transient protection, isolation, and central office loop-back testing capability.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer communication protocol between two routers directly without any host or any other networking in between. It can provide loop detection, authentication, transmission encryption, and data compression.
In telecommunications, a channel service unit (CSU) is a line bridging device for use with T-carrier, which
A data service unit, sometimes called a digital service unit, is a piece of telecommunications circuit terminating equipment that transforms digital data between telephone company lines and local equipment. The device converts bipolar digital signals coming ultimately from a digital circuit and directly from a Channel service unit (CSU), into a format compatible with the piece of data terminal equipment (DTE) to which the data is sent. The DSU also performs a similar process in reverse for data heading from the DTE toward the circuit. The telecommunications service a DSU supports can be a point-to-point or multipoint operation in a digital data network.
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.
In telecommunications, a network interface device is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring. Outdoor telephone NIDs also provide the subscriber with access to the station wiring and serve as a convenient test point for verification of loop integrity and of the subscriber's inside wiring.
Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. Fibre Channel is primarily used to connect computer data storage to servers in storage area networks (SAN) in commercial data centers.
Colorado State University is a public land-grant research university in Fort Collins, Colorado. It is the flagship university of the Colorado State University System. Colorado State University is classified among "R1: Doctoral Universities – Very high research activity". It was founded in 1870 as Colorado Agricultural College and assumed its current name in 1957.
A leased line is a private telecommunications circuit between two or more locations provided according to a commercial contract. It is sometimes also known as a private circuit, and as a data line in the UK. Typically, leased lines are used by businesses to connect geographically distant offices.
California State University, Sacramento is a public university in Sacramento, California. Founded in 1947 as Sacramento State College, it is part of the California State University system.
BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards protocol.
A CSU/DSU is a digital-interface device used to connect data terminal equipment (DTE), such as a router, to a digital circuit, such as a Digital Signal 1 (DS1) T1 line. The CSU/DSU implements two different functions. The channel service unit (CSU) is responsible for the connection to the telecommunication network, while the data service unit (DSU) is responsible for managing the interface with the DTE. A CSU/DSU can have an external connection point or it can be integrated into a modular card installed in a router.
The Corporation for Education Network Initiatives in California is a nonprofit corporation formed in 1997 to provide high-performance, high-bandwidth networking services to California universities and research institutions. Through this corporation, representatives from all of California's K-20 public education combine their networking resources toward the operation, deployment, and maintenance of the California Research and Education Network, or CalREN. Today, CalREN operates over 8,000 miles of fiber optic cable and serves more than 20 million users.
BT Wholesale and Ventures was a division of United Kingdom telecommunications company BT Group that provided voice, broadband, data, hosted communication, managed network and IT services to communications providers (CPs) in Great Britain. It was merged with BT's Business and Public Sector division to form BT Enterprise in October 2018.
The California State University police departments(CSUPD) (known within the California State University system as the Cal State Police or University Police) are the police departments of the California State University system. Their police officers are duly sworn peace officers of the State of California, as established by section 830.2(c) of the California Penal Code. There are a total of 23 campuses in the California State University system, each with their own police department. Each campus' police department has its own chain of command; however, some of the policies are system-wide.
Internet in the Czech Republic and Internet access are largely provided by the private sector and is available in a variety of forms, using a variety of technologies, at a wide range of speeds and costs. In 2013, 68% of Czechs were connected to the Internet. From 2013 to 2022, the number of Internet users in the Czech Republic increased rapidly to 91.48%.
The Grand Loop Road is a historic district which encompasses the primary road system in Yellowstone National Park. Much of the 140-mile (230 km) system was originally planned by Captain Hiram M. Chittenden of the US Army Corps of Engineers in the early days of the park, when it was under military administration. The Grand Loop Road provides access to the major features of the park, including the Upper, Midway and Lower geyser basins, Mammoth Hot Springs, Tower Fall, the Grand Canyon of the Yellowstone and Yellowstone Lake.
Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream). Providers usually market ADSL as an Internet access service primarily for downloading content from the Internet, but not for serving content accessed by others.
Dr. Reinhard Brandl is a German politician of the Christian Social Union of Bavaria (CSU) who has been serving as a member of the German Bundestag since 2009, representing Ingolstadt.
