D-Link DGS-3700 series Metro Switches are designed & purpose-built for Metro Ethernet services for Telecom/Service Providers. Its design is based on feld proven experience learnt from multiple Ethernet deployment in Telecoms/Carriers. It supports wide variety of technologies including Ethernet, OAM (Operations, Administration and Maintenance), Double VLAN (Q-in-Q), QoS and Triple play services demanded by Carrier Ethernet networks.

Product Overview
D-Link DGS-3700 series is D-Link Metro switch family optimized for the Ethernet-to-the-Home (ETTH) and Ethernet-to-the-Business (ETTB) services. It comes ready with Service Provider-Friendly hardware, robust software & security features, OAM manageability functions and Triple-Play Services.

D-Link DGS-3700 series comes with:
- D-Link DGS-3700-12 with 8-Port 10/100/1000Mbps + 4 Combo Copper/SFP L2 Management Switch
- D-Link DGS-3700-12G 8-Port SFP + 4 Combo Copper/SFP L2 Management Switch

The SFP Gigabit ports support a wide variety of SFP tranceivers. They include 100Base-FX, 1000Base-LX, 1000Base-SX, 1000BASE-SXM, 1000BASE-LHX, 1000BASE-ZX and Wavelength-Division Multiplexing (WDM) SFP transceivers.

Service Provider-Friendly Hardware
D-Link DGS-3700 series is designed to be deployed in compact and outdoor Telecom/Carriers cabinet. It has a compact form factor of 210 mm in depth in a 1U rack enclosure with operating temperature of up to 65?C. Furthermore, to simplify feld installation, troubleshooting and maintenance, it has all the access connection located on the front panel.

These include:
- 10/100/1000Base-T Ports or SFP Slots
- Modular AC/DC Power Supply
- Modular Fan
- Modular Dust Filter
- RS-232 console port
- RJ-45 OOB management port
- RJ-45 Alarm port
- Grounding

Robust Software & Security

D-Link DGS-3700 series provides extensive VLAN support including Double VLAN (Q-in-Q), Layer 2 Protocol Tunneling (L2PT), GARP/GVRP and 802.1Q to enhance network security and performance. Bandwidth Control can be fexibly set for each port using pre-defned thresholds to assure a committed level of service for end users. For advanced applications, per-fow bandwidth control allows easy fne-tuning of service types based on specifc IP addresses or protocols. Moreover, it has a robust set of multi-layer (L2, L3, L4) QoS/CoS features optimized for Triple-Play Services like Voice over IP (VoIP), Media-on-Demand (MOD), Intranet and video conferencing. Priority queues for 802.1p/TOS/DiffServ are supported, with classifcation and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP port numbers.

D-Link DGS-3700 series provides a complete set of security features, which include IP-MAC-Port Binding (IMPB) with DHCP Snooping, L2/L3/L4 multi-layer Access Control Lists and 802.1X user authentication via TACACS+ and RADIUS servers. In addition, it also offers supression capabilities to enhance network performance and security. To prevent malicious fooding traffc caused by worm/virus infections, the DGS-3700 series in-built Safeguard Engine enforces its reliability, serviceability and availability.

OAM Management
To uphold enterprise customers’ SLA, service providers must reduce the Mean Time to Repair (MTTR) and increase service availability. Ethernet OAM features address these challenges and enable service providers to offer carrier-grade services. D-Link DGS-3700 series supports industry-standard OAM tools including IEEE 802.1ag Connectivity Fault Management and IEEE802.3ah Ethernet in the First Mile. IEEE 802.1ag protocol provide tools to monitor and troubleshoot end-to-end Ethernet networks allow service providers to check connectivity, isolate network issues, and identify customers affected by network issues. IEEE 802.3ah Ethernet in the First Mile protocol provides OAM discovery, local and remote loopback diagnostic on the link between the customers’ equipment and the service provider network.
