Termination word format
Successful call termination occurs by the recep-
tion of a valid address code-word with less than
2 bit errors on the decoder output register.
Unsuccessful termination occurs when sync is
not detected.
Termination word format:
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

Call data output format
The HT9480 automatically converts message
code-words received in numeric or alphanu-
meric format into ASCII format. Depending on
SPF09 and the function bit setting in the re-
ceived address code-word a conversion takes
place as shown in the following table.
F unction Bits

When a conversion from alphanumeric format
to ASCII takes place, the received message
code-words are split into message blocks, seven
bits in length. After adding the error flag they
are transferred as message words.
When a conversion from numeric format to ASCII
takes place, the received message code-words
are split into blocks, four bits in length. Each
four bit block is converted to a seven bit block as
shown in the following table. After adding the
error flag they are transferred as message
words. Refer to the “Numeric format to ASCII
conversion” table.
There is a new message packaging method after
receipt of message code-words. The new mes-
sage packaging method is 4 bits packaging type.
Depending upon SPF20=1, message code-word
conversion takes place as show in the following
table.

The received message code-words are split into
blocks, four bits in length. Each four bit block is
directly transferred to a four bit block. After
adding the error flag they are transferred as
message words.
