DSLAM (Digital Subscriber Line Access Multiplexer)

eslam 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. Already have a Gartner account?

The connection is made with unshielded twisted pair telephone lines through a Public Switched Telephone Network. Customer side is where the customer telephone lines are connected and trunk side is where the dslam connects to the ISP network.

Purchase this Document Price: Balanced pair cable has higher attenuation at higher frequencies. The following coding and IT boot camp facts and statistics provide an introduction to the changing trends in education and training programs.

DSLAMs are most commonly used to provide delam Internet access service; however, they can also be used to provide voice and video service. The DSLAM equipment collects the data from its many modem ports and aggregates their voice and data traffic into one complex composite “signal” via multiplexing. What is your job function? Java is a high-level programming language. One of the most common reasons why slower connections are experienced is due to the amount of traffic on the line at one basiics.

DSLAM hardware includes multiple aggregation cards which are used to connect customers through the several ports on the card. On the customer side each dsllam is configured to supply a data connection via DSL to the customer modem. Which topic are you interested in? Aggregation Cards — the devices which actively move incoming connections to open ports on the system. Each modem on the aggregation card communicates with a single subscriber’s DSL modem. Chassis — the chassis must be able to withstand trauma as well as be properly insulated to prevent unnecessary arcs which may cause damage to the DSLAM and any components.

What is your job title? Gartner delivers the technology-related insight you need to make the right decisions, every day. A typical DSLAM aggregation card will have 24 ports, but different manufacturers produce different options with more or less ports.

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. What is your company size? DSLAMs are also used by hotels, lodges, residential neighborhoods, and other businesses operating ds,am own private telephone exchange. Thanks for a good article. Use as a Multiplexer — The multiplexing abilities of the DSLAM are very complicated and perform the necessary encoding of both voice and data signals through the phone company and through to the ISP.

The process of making this connection possible requires a few exchanges of data.

It’s primary function is to provide broadband connections to subscribers based upon various DSL flavours, e. A DSLAM may or may not be located bassics the telephone exchange, and may also serve multiple data and voice customers within a neighborhood serving area interfacesometimes in conjunction with a digital loop carrier.

DSLAMs are not only used for Internet connections; several hotels, lodges and residential areas as well as businesses utilize them to have their own private telephone exchange or specialized network.

Digital subscriber line access multiplexer

This traffic is routed through the backbone switch through an Access Network which connects through the Internet Backbone. The speed of the connections is really up to several factors but the three most important functions of the DSLAM are:.

Vasics modem will attempt to train by dialing the appropriate access number to the DSL service provider through the local loop.

User traffic is mostly IP based. Cabling — the DSLAM requires a dslm amount of cables to be routed within its chassis to make all of the connections possible. The data must travel between these points and is routed to the appropriate destination to make the Internet connection valid.

This is due to the nominal line impedance measured in Ohms but comprising both resistance and inductance of balanced lines being somewhat lower than that of UTP, thus supporting ‘weaker’ signals however the solid-state electronics required to construct such digital interfaces are more costly.

The cslam is the process through which the data must travel to make the connection:. Join to subscribe now. It provides the digital communications from a customer’s premise equipment–DSL modems or DSL routers–to the provider’s central office site via digital subscriber line technology over existing standard telephone twisted-pair copper wiring.
