DSLAMDigital Subscriber Access Multiplexer
DefinitionA 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 usingMultiplexing Techniques. DSLAM multiplexers connect 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). DSL lines with some combination of
Asynchronous Transfer mode (ATM), Frame Relay, or Internet Protocol

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.
ATNG CARD FeatureImplementing 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
System Feature Overview DSLAM can Integrating Data, Voice and Video Carrier-Class Reliability Hot-swap of Subscriber Boards Many Service Interfaces (ADSL/ADSL2/ADSL2+/ SHDSL/ VDSL2/EPON/GPON) Multicast Feature (MVLAN,CAC,PRV,CDR,IGMP v2) Full DiffServ Mode QoS for Triple-Play Multiple Maintenance Modes (CLI, Telnet, SNMP) CPE Remote Management
Base Capacity Features Supporting 16K MAC ;
Supporting 4K VLANs ; Supporting 255 ~ 1K IP Multicast Groups ;
Supporting 512 Traffic Classes; Supporting 128 QoS Policies
