- 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).

- Shelf Configuration Shelf Configuration Mode 1: Mode 1: Holding
subscriber cards without built-in splitters and splitter cards
together, implementing broadband data service and narrowband voice
service access at the same time.

- 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.

- 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.

- 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
button ATNG CARD Feature
