MDW Definition
The received paging message will be output as MDW1, MDW2 ....MDWn format (MDW group).
md17
md0 are the actual paging message data resolved from the message partition, including
terminator character EOM and any dummy bit such as a filler. For any submessage of a long message,
μ
C needs to use AIW's lc15
lc0 to truncate terminator or dummy bit from md17
md0 according to AIW
description. While remote programming, rd17
rd0 is used for remote programming data only. RPI is the
remote programming index received from system. This bit should be loaded into b147 of option bit
during the re-initialization stage if the remote address is programmed.

Table 34. MDW bit description
Any paging message such as 7 bit alphanumeric, 4 numeric or transparent data will be placed
continuously in the 18 bit information field, md17
md0. After the last character (or bit) of message the
following message termination procedures shall be used:
Alphanumeric: an EOM character (0010001) shall be appended;
Numeric: no terminating character required;
Transparent data: a single bit set to one shall be appended;
