DSLAMs are very complex pieces of equipment and are basically designed to make connections as fast as possible between different locations. What is your job title? Slow speeds are usually due to varying data rates with distances dslxm than 2 kilometers and the amount of traffic on the lines. Each modem on the aggregation card communicates with a single subscriber’s DSL modem.

Views Read Edit View history. Collection of Modems — The DSLAM is also a large collection of modems which are designed to patch the customers dslwm to their appropriate services. Improve performance, reduce risk and optimize return on your investments through our combination of research insight, benchmarking data, bbasics methodologies and hands-on experience.

The connection is made with unshielded twisted pair telephone lines through a Public Switched Telephone Network. A list of speeds and the distance required to achieve these speeds follows:. DSLAMs not only provide the central office connection for the customer’s digital subscriber line, but they also perform the aggregation of numerous customer digital subscriber lines into basocs combination of asynchronous transfer mode ATMframe relay, or Internet Protocol IP links to a provider’s high-speed communication backbone.

Designing and Deploying Triple-Play Services. In other projects Wikimedia Commons. Each DSLAM has multiple aggregation cards, and each such basicss can have multiple ports to which the customers’ lines are connected.

The central office or a servicing area interface must accept the dialing in of the data from the modem which it then processes through a DSLAM. Mail this article Print this article. Got Something To Say: Please help improve this article by adding citations to reliable sources. The speed of the connections is really up to several factors but the three most important functions of dsslam DSLAM are:. This modem functionality is integrated into the DSLAM itself instead of being done via an external device like a 20th-century voiceband modem.

Digital Subscriber Line Access Multiplexer (DSLAM): An Overview

The speeds will vary for Therefore, it cannot re-route traffic between multiple IP networks, only between ISP devices and end-user connection points. This compensation capability also takes advantage of the better performance of ” balanced line ” DSL connections, providing capabilities for LAN segments longer than physically similar unshielded twisted pair UTP Ethernet connections, since the balanced line type is generally required for its hardware to function correctly.

The longer the distance of the phone lines which will be carrying the signal between the customer and the DSLAM, the lower the quality and speed of the connection will be possible. Thanks for a good article. Article Effortless Experience Explained Read article. The modems within the DSLAM are capable of adjusting the line to remove echoes and other disturbances from the line to compensate and increase the bandwidth for the maximum connection rate possible.

Stay up to date on the latest developments in Internet terminology with a free newsletter from Webopedia. The data rates are specially designed to go a certain speed with these distances in mind and many consumers will never get the full advertised data rate for their Internet connections due to their distance from the DSLAM.

Learn different types of networks, concepts, architecture and Webinar To the Point: This compensation may impact how and where products appear on this site including, for example, the order in which they appear. Use as a Multiplexer — The multiplexing abilities of the DSLAM are very complicated and perform the necessary encoding of both voice and data signals sdlam the phone company and through to the ISP.
