CPRI Application FTTA (Layer 2)
Antenna CPRI Layer 2 RRH Initialization Use the T-BERD to verify provisioning and Radio Head initialization at the top of the tower Application Initialize an RRH and measure basic CPRI parameters such as Initialization Start Up Sequence C&M Channel Type (Fast vs HDLC) Protocol ID Line Rate (Freq Rx) Problems Solved Enables users to verify basic RRH CPRI port operation, provisioning and initialization. Therefore, verifying basic RRH CPRI operation from the bottom of the tower. RRH COAX Fiber T-BERD
