The format of SMDI messages with forwarded calls is as follows:
<CR><LF>MD md-num md-port fwd-type fwd-station<0x20>src-num<0x20><CR><LF><^Y>
The components of this SMDI message format have already been described, with the exception of the following:

As previously mentioned, this indicates the forwarding type, but in this case, the type will be A (forward all calls),
B (forwarded on busy), N (forwarded on no answer), or U (forwarded for unknown reason).

SMDI Messages with MWI On/Off
The format of SMDI messages used with MWI on is as follows:
OP:MWI<0x20>stn-num!<^D>
In this case, OP indicates that an MWI should be turned on for the specified station number, and the <^D> (Ctrl-D) indicates the end
of transmission.
The format of SMDI messages used with MWI off is as follows:
RMV:MWI<0x20>stn-num!<^D>
