Product Description:
16-Port Smart Copper Gigabit Switch With 2 Combo SFP (Mini GBIC)
The DGS-1216T Smart Switch presents a cost-effective solution for the small and medium business to economically implement high-speed Gigabit packet switching with easy fine tuning of network performance and security. This switch comes with 16 copper Gigabit ports and 2 combo SFP (Mini GBIC) for fiber connection. Port trunks are provided for server deployment and network backbone attachment, while functions important for bandwidth-intensive applications such as Priority Queues and VLANs are supported to enable you to implement Quality of Service (QoS) and security without having to go through complex network management usually found in other managed switches.

16 Copper Gigabit Ports
16 copper Gigabit ports provide an inexpensive alternative solution to fiber-optic. Using your existing low-cost Cat. 5 copper twisted-pair wires as the transmission media, these ports allow you to instantly upgrade to Gigabit capability without requiring you to install new, expensive fiber cables. All ports support plug-and-play connections with auto-sensing of 10/100/1000Mbps network speeds, full/half duplex autonegotiation and MDI/MDIX cross over.

2 Combo SFP Slots for Flexible Fiber Connection
2 combo SFP (Mini GBIC) are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for short, medium or long-distance fiber backbone attachment. Use of the mini GBIC will disable their corresponding built-in 10/100/1000BASE-T connections.

Port Trunks for Aggregated Bandwidths
Gigabit ports can be combined together to create multi-link load-sharing aggregated bandwidths to a server or a network backbone. To expand the network, you can also make use of the port trunks to eliminate bottlenecks between the cascaded switches. The DGS-1216T allows you to combine
between 2 and 8 ports per trunk, and to create up to 8 groups of port trunks for a switch.

VLANs for Enhanced Security & Performance
The switch support VLANs to let you improve security and bandwidth utilization by limiting the broadcast domains and confining intra-group traffic within their segments. To segment up the network, VLAN-supported workstations and servers that are connected to the switch can be grouped
into different Virtual LANs (VLANs).

Quality of Service Support
The switch supports not only Layer 2 802.1p Priority Queue control, but also other ways to prioritize network packets. Classification of users data priorities can be based on a data packet Priority Queue or the TOS field in the IP header. This QoS function support allows you to run bandwidth-intensive/delay-sensitive applications and to attach video servers to the switch for video conference.
