Edgecore Networks offers 400G disaggregated cell site gateway for 5G mobile networks

June 27, 2022
The CSR440 is designed to offer 5G mobile network operators an open and disaggregated cell site gateway that will accept network operating software (NOS) from such vendors as RtBrick, ADVA, IP Infusion, and Capgemini.

Edgecore Networks, a wholly owned subsidiary of Accton Technology Corp., has unveiled the CSR440, a 400G addition to its line of disaggregated cell site gateways (DCSGs) based on the Telecom Infra Project’s specification work (see “Telecom Infra Project targets disaggregated cell site gateways”). The CSR440 is designed to offer 5G mobile network operators an open and disaggregated cell site gateway that will accept network operating software (NOS) from such vendors as RtBrick, ADVA, IP Infusion, and Capgemini. The platform also can be used as a broadband network gateway (BNG), the company asserts.

The CSR440 features 1/10/25-Gbps, 50/100-Gbps, and 100/400Gbps interfaces. Via a server-grade, 8-core, hyper-threading Intel Xeon processor and a Broadcom Qumran2a chipset, the DCSG offers 800-Gbps switching capacity with what Edgecore describes as “advanced features.” For example, the CSR440 supports IEEE 1588v2 full timing features with Class C accuracy and is capable of providing an 802.1CM Time Sensitive Networking (TSN) interface. The latter supports SRv6 technology and eCPRI encapsulation for upcoming xHaul applications and deployments. The CSR440’s 400G ports will accept high-powered optics that extend service range as well.

“Edgecore's flagship 400G Cell Site Router CSR440 brings high-bandwidth connectivity to the access edge of our customer networks. Customers who are upgrading their network infrastructure using the temperature-hardened CSR440 can meet 5G backhaul and xHaul requirements at remote cell sites. Together with Edgecore's software partners supporting the CSR440, we are accelerating the adoption of open networking for 5G and BNG applications,” said Nanda Ravindran, vice president of product management at Edgecore Networks.
