Key Feature

• Friendly user interface for various application environments
• Support connection to broadband Internet services with high productivity of IP routing and transparent learning bridge.
• Complete ATM protocol stack implementation over SHDSL
• Support PAP/CHAP/MS-CHAP user authentication on PPPoE/PPPoA
• Support SNMPv1/SNMPv2 agent and MIB II of SNMP management
• Support craft Console (RS-232) and remote management (Telnet or HTTP) via TCP/IP network and allow local or remote problems shooting in detail
• NAT/PAT feature lets user both conserve valuable IP address space and reduce IP address management, meanwhile, also protects certain attack from outer network or internal workstations.SNMP management with SNMPv1/SNMPv2 agent and MIB II
