Both the AGCV208S and AGC7008S from the Open Networking AG series are designed as Disaggregated Cell Cite Gateways (DCSG) in the TIP (Telecom Infra Project) OOPT project, which offer an open and disaggregated architecture for existing 2G, 3G, 4G and future 5G mobile network infrastructures.

Based on Broadcom’s DNX series, the AGCV208S provides 300G switching capacity while the AGC7008S provides 120G bandwidth for smaller applications.

Both platforms come with the same form factor for indoor and outdoor installation with wide operation temperature, in a fully equipped 1RU box with a wide array of connectivity options including 1G, 10G, 25G and 100G. Multiple time injection interfaces, such as 1PPS, 10MHz, GPS and BITS enable you to deploy these boxes in different topology and application.

“With end-to-end traffic management capability, DNX series provide a scalable and programmable platform for mobile network operators,” said Guy Lange, PM of Broadcom’s CSG Group.

The exponential growth of data traffic is driving carriers and service providers to adapt the disaggregation model to meet the requirements of the coming generation of networks, particularly in the area of mobile connectivity. The disaggregation of hardware and software helps to add new services more easily and substantially reduces capital and operating costs (CAPEX and OPEX) while dramatically cutting time to market. Conventional gateways in 2G, 3G and 4G networks would have to be equipped with extensive capacity and connectivity upgrades to achieve the performance required for 5G base stations.

Disaggregated Cell Site Gateways Sub-group Co-chair, Luis Martin Garcia, pointed out that “we are happy to see Delta joining DCSG project and bringing new designs and innovation to this project. Most importantly, the entire industry could also benefit from the open design.”

Technical specifications include:

  • Compact 1RU, Hardened Design with a depth of 295 mm;
  • Future proof 1GE, 10GE, 25GE and 100GE connectivity;
  • Programmable, scalable platform based on Broadcom DNX family with H-QoS and Buffering);
  • Multiple time synchronization interfaces: 1PPS, 10MHz, GPS, ToD and BITS;
  • Supports BroadPTP and Microsemi time synchronization;
  • Supports SyncE and 1588 V2;
  • All front maintenance design to reduce operation efforts;
  • AC and DC Redundant PSUs.
