Robust System Design
ZyXEL GS-1548 are 48-port L2 Gigabit switch with advanced Web-based management support, and it's specially designed for SB/Enterprise networks where extra bandwidth and advanced QoS or security features are required. To cope with the diverse requirements of SB/Enterprise businesses, the ZyXEL GS-1548 Web-managed switch comes with 40 Gigabit copper ports plus 4 dual-personality (RJ-45/SFP) Gigabit ports to provide 96 Gbps of non-blocking connectivity for SB/SMB networks. With the flexible multi-function design, GS-1548 fits any network with very little effort.

Evolution New Managed Power
While many legacy Web-based Smart switches improve manageability, configuration complexity is still an issue; for most SB/Enterprise, inadequate IT expertise and complicated configuration are the major concerns to overcome. Powered by the next-generation hardware platform with a content-aware engine, ZyXEL GS-1548 delivers stress-free networking. In addition, the streamlined and intuitive Web-GUI makes GS-1548 even easier to configure to slash the efforts needed.

Auto DoS Attack Prevention
Security is becoming increasingly important in SB/Enterprise networks. Equipped with Auto DoS Attack Prevention, the GS-1548 is capable of protection against ubiquitous DoS attacks. A few mouse clicks are all it takes to initiate the protection, complete the once-complicated ACL setting and reduce operating efforts dramatically. The GS-1548 supports 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and dynamic ARP to establish a strictly protected network.

Auto VoIP Optimization
Migration to VoIP is the key to differentiate business competitiveness. It usually requires IT expertise to optimize a network for VoIP applications. With emergence of the "Auto VoIP" feature, however, the GS-1548 can identify VoIP packet patterns and grant the highest priority to establish a VoIP-friendly communication automatically. "Auto VoIP" offers IP telephony without configuration headaches; features such as four priority queues and the WRR (Weighted Round Robin) scheduling algorithm are usually deployed on enterprise networks, allowing users to optimize network bandwidth usage and implement QoS (quality of service). In terms of bandwidth management and switch interconnections, users can choose from several options and pick the most appropriate with just a mouse click.
