Service Delivery Switch

The 3905 is a compact and rugged Ethernet service delivery platform purpose-built to support small cell mobile backhaul applications. It supports all of the necessary features that mobile network operators and wholesale mobile backhaul service providers require to guarantee strict and differentiated SLAs.

Purpose-built: compact and rugged

The 3905 is a carrier-grade Ethernet service delivery platform housed in a hardened enclosure—making it ideal for harsh outdoor installations, as well as unconditioned indoor installations where environmental controls are unavailable. This increased flexibility leads to lower operating costs. The 3905 enclosure supports a wide variety of the mechanical mounting options required for varied small cell installations on poles, masts, strands, and the sides of building walls.

Power-over-Ethernet Plus flexibility

The 3905 offers standards-compliant Power-over-Ethernet Plus (PoE+) capabilities that greatly facilitate installations by directly powering subtended small cell radios with the same cable used for the network connection. This flexibility yields simpler, rapid, and highly cost-effective deployments. PoE+ can also be leveraged for other applications, including intelligent transport systems, the Internet of Things via subtended sensors, video surveillance networks, and Ethernet business services.

Synchronization and timing

The 3905 has been designed to deliver accurate and scalable frequency, phase, and time across the packet network in some of today’s harshest environments. The capability enables support of applications such as mobile backhaul, synchronization as a service, or smart grid aggregation in either a wholesale environment or a self-managed network.
