DSW2748G
NARAJANGTOH Identification Number:
DAYOU NETWORKS DSW2748G is L2 Gigabit Ethernet Switch as a high-end interface to support a variety of multimedia services (IPTV TPS).
L2 switch has been developed to fit the needs of customers who wants to build a high-speed network environment, as the cost of the optimal 48port 10/100/1000Base-T interface, and to provide the service port, 100/1000Base-X interface and four uplink ports L2 aggregation switches to provide. Multicasting, QoS, Security, etc. Based on the outstanding performance is a system that provides a high-performance, high-quality, reliability.
Network systems management
SNMP v1/v2, MIB II, RMON MIB, and applied to the remote network management can be more easily.
Improved performance
Non-blocking Switching fabric for high-performance stable and 104Gbps switching capacity and up to speed packet processing 77.4Mpps support.
High Performance Network
DSW2748G as a high-performance network services supported by the Switch's Ethernet-based data, video, and voice services for optimal network environment.
