SMC1: Transmit Data
The SMC interface consists of SMTXD, SMRXD, SMSYN, and a clock. Not
all signals are used for all applications. SMCs are full-duplex ports that
supports three protocols or modes: UART, transparent, or general-circuit
interface (GCI).
Serial Interface 2: Layer 1 Strobe 3
The MSC8103 time-slot assigner supports up to four strobe outputs that
can be asserted on a bit or byte basis. The strobe outputs are useful for
interfacing to other devices that do not support the multiplexed interface or
for enabling/disabling three-state I/O buffers in a multiple-transmitter
architecture. These strobes can also generate output wave forms for such
applications as stepper-motor control.
FCC2: Clear To Send
In the standard modem interface signals supported by FCC2 (RTS, CTS,
and CD). CTS is asynchronous with the data.
SMC1: Receive Data
The SMC interface consists of SMTXD, SMRXD, SMSYN, and a clock. Not
all signals are used for all applications. SMCs are full-duplex ports that
supports three protocols or modes: UART, transparent, or general-circuit
interface (GCI).

FCC2: Carrier Detect
In the standard modem interface signals supported by FCC2 (RTS, CTS
and CD). CD is asynchronous with the data.
