DCSG is a 1RU fully-featured cell site router with a wide range of Ethernet connectivity options for client and network sides. As a cell site gateway, DCSG supports Layer-2, Layer-3 and MPLS features - with native time synchronization protocols such as IEEE-1588 v2 and Synchronous Ethernet for the mobile base stations.
Mobile base stations typically connect to a cell site gateway using RJ45 or SFP Gigabit Ethernet interfaces. However, to accommodate the increased capacity required in modern 4G and coming 5G networks, base stations will also use 10 Gigabit Ethernet SFP+ interfaces. This makes most cell site routers currently deployed unsuitable to carry 5G base station traffic.
The Open Optical & Packet Transport (OOPT) Project Group within the Telecom Infra Project (TIP), in conjunction with several leading global mobile operators - Vodafone, Telefonica, TIM Brasil, BT, and Orange - produced the definition of an open white-box cell site gateway device that operators can widely deploy in their current 2G/3G/4G cell sites, but that also supports the port speeds and densities which will be required for 5G networks.
