The time is in the unit of nanosecond for provisioned target delay. The parameter is available only when CPRI port is set to structure-aware mode. Represent the provisioned target delay - In DL path : BBU CPRI egress to remote TPS CPRI egress - In UL path : remote TPS CPRI ingress to BBU CPRI ingress - For remote TPS provision : target-offset should be based on DL path. - For hub TPS provision : target-offset should be based on UL path. This parameter is used to calculate the TPS CPRI egress presentation time setting (ie CPRI 10ms frame boundary is egress at specific presentation time based on TPS timebase traceable to global time reference). All demapper buffers are egress based on this alignment. The offset time should be designed considering all factors introducing latency, i.e., network transmission latency, Ethernet switch forwarding latency, RoE encap/decap latency, jitter buffer depth, timebase difference between mapper and demapper. This parameter can be modified at run time, but the corresponding RoE demapper should be shut-down and no shutdown so that the decapsulated CPRI signals are played out at the presentation time.
