Ciena 170-3916-906 is a Carrier Ethernet Service Delivery Switch (SDS) from the Ciena 3916 platform.

It is a 2-port (expandable service delivery/demarcation switch) used by service providers to deliver, monitor, and enforce Ethernet services with strict SLA (Service Level Agreement) control.

This device is commonly deployed at:

• Customer premises (CPE / demarcation point)
• Metro Ethernet networks
• Carrier access networks
• Service provider edge networks

Its main role is to provide:

• Service demarcation (UNI/NNI separation)
• QoS enforcement
• SLA performance monitoring (RFC 2544 / Y.1564)
• Carrier-grade Ethernet service delivery

? KEY FEATURES

• Carrier Ethernet Service Delivery Switch (3916 platform)
• 2 × Ethernet service ports (model-dependent configuration)
• Advanced QoS (Quality of Service) enforcement
• SLA monitoring and performance testing (RFC 2544 / Y.1564)
• Carrier-grade OAM (Operations, Administration & Maintenance)
• MEF-compliant Ethernet service demarcation
• Compact rack-mountable form factor
• Designed for service provider networks
