ZyXEL ES-1528 comes with 24 Fast Ethernet copper ports plus four Gigabit uplinks (two 1000Base-T ports and two SFP slots) that fire up the non-blocking connection power to 12.8Gbps on SMB/SB networks, and its multi-function design fits into copper or fiber networks easily. By utilizing 4G uplinks and port aggregation, bandwidth on critical paths can be expanded flexibly by merging multiple traffic pipelines into a logical one to dramatically improve network stability. While many legacy Web Smart switches improve manageability, complexity is still around. For most SMB/SB, inadequate IT expertise and complicated configuration are the major pains to overcome before getting connected. Powered by newest hardware platform with smart ACL technology behind, "Auto Dos Attack Prevention" and "Auto VoIP" empowers hassle-free operations required by a network with strict protection and VoIP-friendliness. In addition, ZyXEL ES-1528 comes with a streamlined intuitive Web-GUI for features demanded by SMB/SB; such as 802.1Q VLAN, 802.1p traffic priority and static port aggregation. Without awkward configurations and bulky user guide, the ES-1528 gives real stuff for SMB/SB networks to enjoy the convenience. Security is the top priority for SMB/SB networks. Equipped with Auto Dos Attack Prevention, the ES-1528 is capable of fighting 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. ES-1528 supports 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and dynamic ARP to establish a strictly protected network. VoIP is a key to differentiate business competitiveness. It usually requires IT expertise to optimize a network for VoIP applications. With the emergence of the "Auto VoIP", however, the ES-1528 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 like four priority queues and WFQ scheduling algorithm allow users to optimize network bandwidth usage and quality of services. In term of bandwidth management, users can choose from several options and pick the most appropriate with just a mouse click.
