DSLAM ADSL ADSL2+ Tripple Play 

DSF2048 is a compact ADSL2+ IP DSLAM with a capacity of 12, 24 or 48 ADSL ports. It performs traffic multiplexing and aggregation from 48 ADSL subscribers to an Internet router through one or two 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.

DSF2048 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.

IP DSLAM ADSL2+

DSF2048 brings Internet access services in community environments -hotels, campus, etc. It is a cost effective solution for Internet Service Providers in far low population density areas.

DSF2048 is managed through CLI commands, Snmp or a user friendly Web interface. It is a compact 19'' product with either a 110-230 Vac mains input, or dual redundant 48 Vdc power supplies.
