The parameter is available only when - CPRI port is set to structure-aware mode - sa-type = 1 (for AxC data) Specifies each AxC frame start offset relative to CPRI 10ms frame boundary. - For hub TPS provision: This parameter is for DL path (in mapper) and UL path (in de-mapper) - For remote TPS provision: This parameter is for UL path (in mapper) and DL path (in de-mapper) For BBU-TPS application, setting to default value = 0 is sufficient. This parameter can be modified only when roe is shutdown. And the modification of this parameter may cause traffic interrupt and need to modify it in both roe mapper and demapper so that the new value can work. Default value for this attribute is 0.
