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.
