S/UNI®-JET Data Sheet
Released
With the 26-byte word structure, if the HCSB bit in the TXCP-50 is logic one, then no HCS byte
is inserted on the data read from the Utopia interface or on the Idle cells. In such a configuration,
the RXCP-50 should be configured to pass the 26-word output without requiring cell delineation
by setting the CCDIS bit to logic one. This setting is useful for passing arbitrary payload through
the transmit and receive Utopia interfaces.
