Table 22 shows the mapping of TelecomBus control bytes and signals into 8B/10B control
characters. When the TelecomBus control signals conflict each other, the 8B/10B control
characters are generated according to the sequence of the table, with the characters at the top of
the table taking precedence over those lower in the table.

Note there can be multiple V5s per SBI frame when in DS3 or E3 mode but only one justification can
occur per SBI frame. Positive and negative justification request through V5 required by the SBI336S
interface should be limited to one per frame.
Note fractional rate links are symmetric in the transmit and receive direction over SBI336S. When using
clock slave mode with a fractional rate link the clock master makes single byte adjustments to the
slaves rate once per frame.
