eAxC_ID Composer / Decomposer for 5G/O-RAN fronthaul

eAxC_ID Composer / Decomposer is an interactive tool for working with O-RAN fronthaul eAxC_IDs, where the 16-bit identifier is split into DU_Port_ID, BS_ID, CC_ID, and RU_Port_ID fields. Instead of hardcoding a fixed bit layout, the tool lets you define each field's bitmask yourself, so it adapts to any O-RAN eAxC_ID convention — including non-contiguous bit assignments — and flags overlaps or uncovered bits in real time on a live bit-grid.

It supports two workflows: Construct, where you enter base DU_Port_ID/BS_ID/CC_ID/RU_Port_ID values and generate 4 eAxC_IDs by incrementing RU_Port_ID (useful for spinning up IDs across antenna ports/layers); and Decompose, where you paste in any eAxC_ID (decimal or hex) and instantly see its constituent field values in decimal, hex, and binary.
