What is DSLAM and how does it work?
It allows a LAN subscriber to connect to the digital subscriber's loop access multiplexer (DSLAM) at the central office over a regular analog su bscriber line or telephone line. Thus, the subscriber can access the ATM/IP backbone or the Internet to enjoy services such as high-speed data communication and video on demand (VoD).
What is IP -DSLAM (Internet Protocol digital subscriber line access multiplexer)?
IP -DSLAM stands for Internet Protocol Digital Subscriber Line Access Multiplexer. User traffic is mostly IP based. Traditional 20th century DSLAMs used Asynchronous Transfer Mode (ATM) technology to connect to upstream ATM routers/switches.
What is a DSLAM chassis?
For example, a DSLAM chassis that supports VDSL and ADSL line cards gives service providers the advantage of delivering high-speed broadband to customers in short (using VDSL) and long distances ranges (using ADSL). To learn more about the difference between VDSL and ADSL, click here.
What is Ethernet DSLAM?
Ethernet, such as Metro Ethernet, can be used for both carrier backbone and access network segments. Ethernet DSLAMs, or IP DSLAMs, transmit IP-based data known as frames as opposed to ATM-based packets, or cells. Unlike ATM cell relay, frame relay is a packet switching technology that transmits different sized frames.
