The IP offers the following features:
- Compliant with the eCPRI Specification V2.0 (2018-06-25) available on the CPRI Industry Initiative (CII) website.
- eCPRI radio equipment controller (eREC) and eCPRI radio equipment (eRE) module configurations.
- Ethernet headers in a variety of formats, including VLAN tag, source/destination MAC address, IPv4, UDP extraction and encapsulation.
- eCPRI one-way delay measurement based on IEEE Standard 1588 Precision Time Protocol (1588 PTP) hardware timestamp. Full hardware support, and required 1588 PTP software stack.
- 25 Gbps and 10 Gbps Ethernet ports.
- Pairing of eCPRI IP with O-RAN IP.
- Interworking function (IWF) type 0 between eCPRI node and one CPRI node.
- Ethernet streaming frame size up to 9,000 bytes as defined by Ethernet jumbo frames standard.
- Packet classifier to classify eCPRI packet and send packets to eCPRI IP. The IP redirects all other packets to external port for user processing.
- Programmable packet queue (maximum 16 entries) holds incoming packets when eCPRI packets transmission in progress.
- Arbitration between eCPRI packet and external incoming Ethernet frames, e.g., Control & Management (C&M) and synchronization packets.
- Mapping logic between eCPRI message physical channel ID to VLAN/MAC address CSR.
- Single distributed unit (DU) and up to eight radio unit (RU) configurations using source/destination MAC address CSR.
- All eCPRI message types compliant to eCPRI specification v2.0
- Input and output ports compliant with Avalon® streaming interface .
