Definition A DSLAM is a Network Device, usually placed at a
Telephone Company Central Office, That Receives Signals from
multiple customer of DSL Connections and puts the signals on a
high-speed backbone line using Multiplexing Techniques. DSLAM
multiplexers connect DSL lines with some combination of
Asynchronous Transfer mode (ATM), Frame Relay, or Internet Protocol
Networks. DSLAM enables a phone company to offer business or home
users the fastest Phone Line Technology (DSL) with the fastest
backbone Network Technology (ATM).

Backplane of DSLAM Subscriber shelf supports three backplanes:
MDCA: Supports broad/narrow-band integrated service access
Mechanical support for all cards and works with the control and
switch card MDCE: Supports pure broadband service access MDCF:
Backplane works with the control and switch card to supports larger
bandwidth, each slots bandwidth reaching up to 4 GE. Provides two
10G interface uplink slots. Splitter shelf supports only one
backplane e.g. MTAN.
Slide 17
CSC Board Feature The CSC board resides in slot 9 and 11.The
CSC board cannot reside in other slots. Height: 9U Core of
switching and controlling for the system, providing a series of
ports and powerful switching capability on the backplane. DSLAM can
be configured with one single CSC card or dual active/standby CSC
cards. When the active and standby CSC cards are running, the
standby CSC card performs hot backup for the active CSC card.
Slide 18
Implementing the conversion between the ATM and the Ethernet
Provide 32 lines of ADSL access for subscribers. The subscriber
data are transferred through PSTN networks. Built-in splitter
Provide LED indicator, 32 link LED indicators, sockets, and reset
