Table 6 - Reset Status
Transmit AIS Operation
The pin TAIS (Transmit AIS, pin 60 in PLCC, pin 48 in
MQFP) allows an all ones signal to be transmitted
from the point of power-up without the need to write
any control registers. During this time the IRQ pin is
tristated. After the interface has been initialized
normal operation can take place by making TAIS
high.
National Bit Buffers
Table 7 shows the contents of the transmit and
receive Frame Alignment Signals (FAS) and Non-
frame Alignment Signals (NFAS) of time slot zero of
a PCM 30 signal. Even numbered frames (CRC
Frame # 0, 2, 4,...) are FASs and odd numbered
frames (CRC Frame # 1, 3, 5,...) are NFASs. The bits
of each channel are numbered 1 to 8, with bit 1 being
the most significant and bit 8 the least significant.
Table 7 - FAS and NFAS Structure
Table 8 illustrates the organization of the MT9075A
transmit and receive national bit buffers. Each row is
an addressable byte of the MT9075A national bit
buffer, and each column contains the national bits of
an odd numbered frame of each CRC-4 Multiframe.
The transmit and receive national bit buffers are
located at page 0DH and 0EH respectively.
Table 8 - MT9075A National Bit Buffers
Note that the Data Link (DL) pin functions, if
selected, override the transmit national bit buffer
function.
