6100 BSC Programming Manual

6100 BSC Link and Station Management
Receive Clock (RxC)
This signal is always used to clock incoming data.
Transmit Clock (TxC)
If the SYSGEN entry indicates that the modem supplies the
transmit clock--that is, if you didn't specify the BSCINTERNALCLK
parameter--this signal is used to clock transmit data, and the
modem determines the speed.
Terminal-Supplied Transmit Clock (TxCO)
If the SYSGEN entry indicates that the LIU supplies the transmit
clock--if you specified the BSCINTERNALCLK parameter--this signal
is used to clock transmit data, and the modem determines the
speed. This option usually implies that there are no modems
on the link, that a cable (not a communication line) connects
the two stations.
