DreamSys4000

It is a composition of Dream

DreamSYS4000 System is the Symmetrical DSL(Digital Subscriber Line) LAN/PSTN Network Access System and performs the LAN traffic transferring function between LAN-to-LAN end-points through the existing single pair telephone line without extra network equipment such router and DSU.

DreamSYS4000 System can optionally supply the telephone service and also, the data and telephone services can simultaneously be performed on the single DSL line. Telephone service has the very stability by using the In-Band channel of the DSL that never affects the line characteristics during the telephone ringing and hook on/off status. And also, it is possible to supply telephone service constantly at the emergence state such as subscriber power-down.

DreamSYS4000 System uses the Multi-rate DSL line coding that can extend to the maximum distance by choosing the most adequate line bandwidth. Therefore this Multi-rate DSL line coding can supply the most cost-effective and the high speed and high band-width Internet/Intranet DSL services.

DreamSYS4000 System has the maintenance system using the SNMP and Telnet-based environment, therefore, effectively performs the various management and administration on the remote and local sites.

As DreamSYS4000 System is composed to independent shelf unit, it is very convenient to install system and expand the subscriber capacity.
