Kentrox DSU-DSUs- Data Service Units

American Tech Supply carries a complete line of Kentrox DSU, DSU, DSU's,Kentrox DSUs, Data Service Units, Kentrox Data Service Units. Kentrox Data Service Unit/Channel Service Units (DSU/CSUs) are renowned for their performance, reliability, and broad range of features. DSUs are WAN access devices that combine the data formatting of a DSU with the FCC-mandated line protection and diagnostic capabilities of a CSU. Basic DSU/CSUs are ideal for networks where there are no requirements for remote diagnostics or any form of centralized management.Basic DSU/CSUs are ideal for networks where there are no requirements for remote diagnostics or any form of centralized management.

Managed DSU/CSUs provide a way for an IT manager to view many remote devices from a centralized monitoring console. Managed DSU/CSUs can also generate alarms when certain network events occur, and forward those alarms to the management console to assist in network troubleshooting. A managed DSU/CSU typically includes an SNMP-compatible agent and supports standard interface MIBs.Frame Monitoring DSU/CSUs include the management features of a managed DSU/CSU, and can also monitor the performance of the public Frame Relay networkIn addition to monitoring Frame Relay SLA (Service Level Agreement) performance parameters, this class of DSU/CSU can also determine bandwidth usage peaks and can be used to correctly size the WAN service (FR port and PVC). The Frame Monitoring DSU/CSU provides the means for the IT manager to determine the optimal balance between performance and cost.

Although slightly more expensive to purchase than a basic DSU/CSU, a managed DSU/CSU can significantly reduce service outage time because of its diagnostic capabilities.Frame Monitoring DSU/CSUs include the management features of a managed DSU/CSU, and can also monitor the performance of the public Frame Relay network. In addition to monitoring Frame Relay SLA (Service Level Agreement) performance parameters, this class of DSU/CSU can also determine bandwidth usage peaks and can be used to correctly size the WAN service (FR port and PVC). The Frame Monitoring DSU/CSU provides the means for the IT manager to determine the optimal balance between performance and cost. Many businesses transmit data, voice and video over a WAN and use DSU/CSUs to connect multiple types of communications equipment. For integrating voice and data, you need the carrier to provide an integrated voice/data service. You also need an add/drop port on the DSU/CSU, which allows you to combine a data interface (V.35) and a fractional T1 or E1 onto a single WAN connection.

If business traffic levels from a PBX are relatively low, significant cost savings can be achieved by integrating these data traffic sources onto a single T1 connection.D-SERV II 56/64kbps DSU/CSU from Kentrox supports high-speed LAN-to-LAN internetworking, video conferencing services, Frame Relay, and Internet access. The D-SERV II provides a high quality, economical solution for the network termination of 56/64 kbps clear channel digital services. Easy to use and configure, the D-SERV II installs in minutes, providing plug-and-play operation for most common services. It features a built-in test pattern generator and error indicator along with a full complement of front-panel LED indicators affording "at-a-glance" system monitoring. On multi-point networks, the D-SERV II's anti-streaming feature prevents a streaming DTE from affecting communications to operating network sites. The D-SERV II 56/64 DSU/CSU's low power requirements (8 watts from standard 115 VAC outlet) and exceptional price provide for economical and cost effective deployment and operation.

WHAT IS A CSU?- WHAT IS A DSU?

A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts digital data frames from the communications technology used on a local area network (LAN) into frames appropriate to a wide-area network (WAN) and vice versa. For example, if you have a Web business from your own home and have leased a digital line (perhaps a T-1 or fractional T-1 line) to a phone company or a gateway at an Internet service provider, you have a CSU/DSU at your end and the phone company or gateway host has a CSU/DSU at its end.

The Channel Service Unit (CSU) receives and transmits signals from and to the WAN line and provides a barrier for electrical interference from either side of the unit. The CSU can also echo loopback signals from the phone company for testing purposes. The Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.35 frames from the LAN and the time-division multiplexed (TDM) DSX frames on the T-1 line. The DSU manages timing errors and signal regeneration. The DSU provides a modem-like interface between the computer as Data Terminal Equipment (DTE) and the CSU.

Short for Channel Service Unit/Data Service Unit. The CSU is a device that connects a terminal to a digital line. Typically, the two devices are packaged as a single unit. The dSU is a device that performs protective and diagnostic functions for a telecommunications line. You can think of it as a very high-powered and expensive modem. Such a device is required for both ends of a T-1 or T-3 connection, and the units at both ends must be set to the same communications standard.

The CSU can also echo loopback signals from the phone company for testing purposes. The Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.xx frames from the LAN and the time-division multiplexed (TDM) DSX frames on the T-1 line. The DSU manages timing errors and signal regeneration. The DSU provides a modem-like interface between the computer as Data Terminal Equipment (DTE) and the CSU.

CSU/DSUs are made as separate products or are sometimes part of a T-1 WAN card. A CSU/DSU's Data Terminal Equipment interface is usually compatible with the V.xx and RS-232C or similar serial interface. Manufacturers of separate unit or integrated CSU/DSUs include Adtran, Cisco, and Memotec.

The CSU originated at AT&T as an interface to their nonswitched digital data system. The DSU provides an interface to the data terminal equipment (DTE) using a standard (EIA/CCITT) interface. It also provides testing capabilities.
