Table 54 - Identification Word
Transmit Slip. A change of state (i.e., 1-to-0 or 0-to-1) indicates that a
transmit controlled frame slip has occurred.
Transmit Slip Direction. If one, indicates that the last transmit frame slip
resulted in a repeated frame, i.e., the internally generated 1.544 Mhz.
transmit clock is faster than the system clock (C4b). If zero, indicates that
the last transmit frame slip resulted in a lost frame, i.e., the internally
generated 1.544 Mhz. transmit clock is slower than network clock.
Updated on an TSLIP occurrence basis.
Transmit Slip Buffer MSB. The most significant bit of the phase status
word. If one, delay through the transmit elastic buffer is greater than one
frame in length; if zero, delay through the receive elastic buffer is less
than one frame in length. Bit is reset whenever page 1 address 17H -
Transmit Slip Buffer Delay - is written to.
Unused.
Transmit Time Slot. A five bit counter that indicates the number of
STBUS time slots between the transmit elastic buffer STBUS write frame
boundary and the internal transmit read frame boundary. The count is
updated every 250 uS.
Transmit Bit Count. A three bit counter indicating the number of STBUS
bit times there are between the transmit elastic buffer STBUS write
frame boundary and the internal read frame boundary. The count is
updated every 250 uS.
