BIIS 1200 operation
The Binary Interchange of Information and Signalling (BIIS)
1200 standard is the best choice to add a data service to an
existing system. It enables digital communications, signalling
and message exchanges with analog transceivers.
The BIIS system provides calling features such as Individual,
Group, and Emergency calls, as well as enables receiving
and transmitting status messages and SDM.
NOTE: During BIIS 1200 operation, dPMR operation is
disabled.
