RD2312-RXD | RD2312 Remote PHY/MACPHY Device (RxD)

In CommScope’s continuing commitment to support a full Distributed Access Architecture (DAA), the RD2312 Remote PHY/MACPHY Device (RxD) supports operation as either an R-PHY Device (RPD) or an R-MACPHY Device (RMD), hence the designation as an RxD. The RD2312 is designed specifically to be deployed in the DC2180 Compact DAA Node. In its first release, the RD2312 is targeted primarily for RMD deployments, whereas the companion product, the CommScope R-PHY S-RPD module, is supported in the DC2180 for RPD deployments.

Specific benefits of the CommScope RD2312 RMD solution include:

Leverages the field-proven and widely deployed software of the CommScope E6000® CCAP Core, which is re-used in the MAC layer of the RD2322 RMD

Utilizes the same software base as the RD2322 RMD, giving it a rich feature suite in its first release
