3.10
Performance Requirement
In this section:
3.10.1 eCPRI
3.10.2 Radio Performance
3.10.3 Power Supply
3.10.1
eCPRI
Line Bit Rate
The 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.
The 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
M anagement Plane ORAN-WG4.M P.0-v02.00
Selecting Recovery Clock
The RU supports the following standards:
■ Telecom Slave Clock (T-TSC) to G8275.1
■ IEEE 1588 (PTP)
■ ITU-T G.8262 (SyncE)
■ IEEE 1914.1
The RU supports Telecom Slave Clock (T-TSC) to G8275.1 and not support G8275.2 and Assisted Partial Timing
Support. Furthermore, the RU supports additional noise filtering to filter fronthaul interface dynamic noise,
which helps meet 3GPP frequency accuracy requirement.
