Sa Facility Data Link Access
The data link interface may be used to source one of the Sa bits. When enabled, this transmit access mode
supersedes all access modes for the selected Sa bit. The receive Sa data is always
present at the receive facility
data link output pin, RFD, along with a valid clock signal at the receive facility clock output pin, RFCK. During an
LFA state, the RFD signal is forced to a 1 state and RFCK continues to toggle on the basic frame alignment. When
basic frame alignment is found, RFD is as received from the selected RSa bit position and RFCK is forced (if
necessary) to the new alignment. The data rate for this access mode is 4 kHz.
Microprocessor Sourcing of the Si and Sa4 to Sa8 Bits
The microprocessor sourcing mode for the Si and Sa4 to Sa8 bits is the control register. Programming PR6, bit 6 to
1 enables the information in the control register corresponding to the Sa4 to Sa8 bits to be transmitted to the line.
Programming PR7, bit 6 to 1 enables the information in the control registers corresponding to the Si bits to be
transmitted to the line. The receive Si and Sa4 to Sa8 bits from the last valid NOT FAS frame are always in the NOT
FAS status register.
CEPT Time Slot 16 X0—X2 Control Bits
The three X bits in frame 0 of the time slot 16 multiframe can be used as a 0.5 kbits/s data link to and from the
remote end. The transmitted line X bits are sourced from the control registers. In the LMFA state, receive X bits = 1
in the status registers.
