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