The Ten-Bit Interface (TBI), defined in IEEE 802.3-2008 clause 36 is a parallel interface connecting the PCS to the PMA and transfers the 8B/10B encoded sequence-ordered sets. The TBI should be used with an external SerDes device to implement the PMA functionality. This mode is not supported for 2.5 Gbps data rates.
