DSM2000  is a modular IP DLSAM complying with ADSL2+ standard aimed at delivering high speed Triple Play Internet access over telephony cables


DSM2000 is a modular ADSL2+ IP DSLAM with a capacity of 24 to 120  ADSL ports. It performs traffic multiplexing and aggregation from 120 ADSL subscribers to an Internet router through two copper or optical Gigabit Ethernet / IP interfaces with Link Aggregation.

It complies with the ADSL/ADSL2+ and ATM standards to deliver 25 Mbps bandwidth to each subscriber. Voice splitters are embedded for cost effective and direct connection to the PBX or dial-up network.

DSM2000 is a layer 2 Ethernet switch and an ATM DSLAM. User traffics are isolated into VLANS with Bandwidth and Quality of Service controls to differentiate multiple classes of stream (Internet, voice, video). Up to 8x ATM VC carries the Ethernet/ IP traffic to the remote user. IGMP enables video stream control.


DSM2000 brings Internet access services in community environments -hotels, campus, etc. It is a cost effective solution for Internet Service Providers in any environment thanks to its extended operating temperature range of -40 to +60 °C.

DSM2000 is a modular châssis with two redundant 48 Vdc power supply. It can host 5 ADSL cards each delivering 24 ADSL ports and a Gigabit Ethernet Processor card. It is controlled through CLI commands, Snmp or a user friendly Web interface.
