52 Gigabit ports: 52 RJ45 with 4 (Combo) SFP 104 Gbps Switching capacity True Plug & Play Supports IP Interfaces and Static Routes QoS with Auto Voice VLANs for VoIP Advanced Security Features D-Link Green Technology IEEE 802.3az Energy Efficient Ethernet
The DGS-1210-52 is perfect for deployment in a VoIP environment, as it support Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service. With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, network administrators can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.
