An interface for digital leased lines which performs loopback testing and line conditioning.
A digital interface device that directly connects end-user equipment to the local digital telephone loop. Often combined with a Data Service Unit to make CSU/DSU.
rime cene nit. Specialized squad of detectives assigned to perform forensics not related to the body at a crime scene. The body forensics are handled by the ME's office. Most members of the CSU are ranked as Detectives, but they do have some "silver shield" investigators.
hannel ervice nit; A device connecting customer T1 equipment and a network line.
A piece of equipment that provides line isolation between the customer premise equipment and a local telephone company services. Also provides alarms, loopback, signal regeneration, line build out, and surge protection. A CSU typically sits between a T1 digital circuit and a telephone system (digital PBX or switch) controlling the T1's 24 voice grade channels. Used in conjunction with Dedicated (T1) Services.

Channel Service Unit. A CSU is a device that interfaces customer T1 (or E1) equipment to a carrier's T1 (or E1) service. At its most basic level, a CSU performs certain line-conditioning and equalization functions, and responds to loopback commands sent from the central office.
Channel Service Unit; the interface from CPE to the public T-1 line
(Channel Status Unit) A device used in conjunction with a T-1 multiplexor that monitors each channel of the T-1 to ensure it is functioning properly.
Acronym for Channel Service Unit, a device furnished as an integral part of a digital access line where a user wishes to supply the bipolar signals. It provides the network with protection against user side electrical anomalies such as surges, and provides the user with network clocking.
Channel Service Unit. The interface to the T-1 line that terminates the local loop.
Channel Service Unit—a device residing between the customer and Central Office equipment that serves to terminate and recondition the digital signal on a circuit. CSU generally refers to equipment terminating a DS1 circuit.

Shorthand for Channel Service Unit. This device is used to terminate the network circuitry at most IVN sites. It performs line conditioning, equalization, and line boosting functions, and can be used as a test point for IVN and telco technicians. There is a CSU at both the end user and network switch ends of your network circuitry. IVN sites are supplied with Milgo CSUs.
Channel Service Unit. (1) In the US, data transmission equipment to repeat the signal from the carrier and ink to CPE. Vendors add value to CSUs by adding performance monitoring and management. (2) In Europe, CSUs are sold for their value features like diagnostics and performance monitoring. The basic repeating function is prd in the NTU (networking terminating unit). CSUs monitor quality on El, E2 or E3 circuits in terms of transmission and line loading. A CSU is a device found on digital links that transfer data faster than modems but does not permit dial-up functions.
Customer Service Unit. A network interface which is placed between the incoming data service line and the customers equipment. This device electrically isolates the customers equipment from the Network, and allows the phone company to perform remote diagnostics and loop-backs for testing purposes.
(Channel Service Unit) A device that connects a terminal to a digital line such as a T1 or DS-3. Similar to a modem, a CSU connects the port that connects you to the telco (SBC SmartJack) and the router or computer . Sometimes referred to as a CSU/DSU. (Data Service Unit)
Computer Software Unit. The lowest level in a breakdown of a software product.
Channel Service Unit. A device used to connect a digital phone line coming in from the phone company to network access equipment located on the customer premises. CSU may also be built into the network interface of the network access equipment.
The hardware interface to a Digital Data Service, for example, a T-1 line. The CSU provides line termination, signal amplification, and has the diagnostic ability to loop a signal back to its source. See also DSU (Data Service Unit).
Channel Service Unit. A unit located on the customer's site that terminates a channel. Used with the customer's logic and timing recovery circuitry.
hannel ervice nit. Connection device for T1/PRI service from a service provider. The CSU monitors the T1 for errors and regenerates the T1 signal.
channel service unit. Premises equipment that complies with Bell Technical Publication 62411 in providing loopback, keep-alive signals, alarm and status conditions.
Channel Service Unit, a device that provides the interface between a customer and the telephone company, typically for 4 wire T1's or FT1's.
Channel Service Unit, is the circuit termination point for the LEC's incoming line. It provides error detection, keep alive, and remote loopback the carrier can use when diagnosing line problems.
channel service unit. An interface between the public switched network and the users digital telecommunications equipment that ensures the appropriate digital signal is maintained into and out of the network.
See channel service unit.
Channel service unit. A digital interface device that connects end-user equipment to the local digital telephone loop. CSU is frequently coupled with DSU (see below) as CSU/DSU.
Channel Service Unit. A CSU sits between the digital line coming in from the central office (i.e. a T1) and devices such as channel banks or data communications devices. A device used to connect a digital phone line (T1 or Switched 56 line) coming in from the phone company to either a multiplexer, channel bank, or another device producing a digital signal. You can buy your own CSU or rent one from your local or long distance phone company.
Channel Service Unit is a digital DCE used to terminate digital circuits (such as DDS or T1 lines) at the customer site. It conditions the line, ensures network compliance with FCC rules, and responds to loopback commands from the central office; it also ensures proper ones density in transmitted bit streams and corrects bipolar violations.
channel service unit. Digital interface device that connects end-user equipment to the local digital telephone loop. Often referred to together with DSU, as CSU/DSU. See also DSU.
Channel Service Unit/Data Service Unit - A device to terminate a digital channel on a Customerâ€(tm)s premise. It performs certain line coding, line-conditioning and equalization functions, and responds to loop back commands sent from the Central Office. A CSU sits between the digital line coming in from the central office and devices such as channel banks or data communications devices. It is found in every digital link and allows the transfer of data at a range greater than 56 Kbps.
Channel Service Unit. A type of customer premise equipment that terminates a T1 access facility to a channel bank, PBX or other equipment capable of supporting a T1 interface.
Equipment installed on customer premises at the interface to phone company lines to terminate a DDS or T1 circuit. CSUs provide network protection and diagnostic capabilities.
Channel Service Unit. A digital interface unit that connects service user equipment to the local digital telephone loop.
Channel service unit. Device that acts as a safe electrical buffer between the customer and a public WAN to prevent faulty equipment from affecting the network.
A component of customer premises equipment (CPE) used to terminate a digital circuit, such as a leased line or T-1/E-1 facility, at the customer site. Performs certain line-conditioning functions and responds to loopback commands from the local exchange. Also, ensures proper ones density in a transmitted bitstream, and performs bipolar violation correction.
