Sending recognised keywords with a call
The keywords listed in Table 54 may be added in a Message call or an AMD message
sent with a call. These keywords are recognised by the firmware in the Envoy™
Transceiver. The firmware expands the keyword by inserting the current information
associated with the keyword into the message.
NOTE: $GPS and $GPS+ keywords require the GPS Call option to be
installed. $GPS+ and $TZ require the MIL-STD-188-141B ALE
option to be installed.
