eCPRI
Line Bit Rate
e RU has one optical interface for eCPRI. Supporting eCPRI a line bit rate of at least 10 Gb/s (10.3125 Gb/s) is
necessary.
e RU is compliant with ORAN 7-2A Spec.
Each plane, for example, control, user, synchronization, management, are compliant with the following
documents:
Control, User, and
Synchronization Plane
ORAN-WG4.CUS.0-v02.00
Management Plane ORAN-WG4.MP.0-v02.00
Selecting Recovery Clock
e RU supports the following standards:
■ Telecom Slave Clock (T-TSC) to G8275.1
■ IEEE 1588 (PTP)
■ ITU-T G.8262 (SyncE)
■ IEEE 1914.1
e RU supports Telecom Slave Clock (T-TSC) to G8275.1 and does not support G8275.2. e RU provides
additional noise ltering to lter fronthaul interface dynamic noise which will help meet 3GPP frequency
accuracy requirement.
