DataTac Modem ID Table
General
Two sites (MOSCAD RTUs) can communicate with one another through the IP Gateway (with
Reflector capability), if both are connected to Private DataTac radios. The MDLC message is
encapsulated and sent over IP to the Gateway. The user ports on the RTUs must be configured
properly and the IP Gateway must have the Modem IDs for both sites. The figure below
depicts such a system.

The DataTac Modem ID Table enables users to define all the DataTac Modems in the system
which are connected to a particular MOSCAD RTU. When the Modem IDs have been defined,
they can be downloaded to the IP Gateway. MDLC communication from one RTU to another
can then be routed through the IP Gateway.
For more information, see the MDLC over Private DataTac chapter in the MOSCAD
Programming Toolbox Application Programmer manual (Advanced Features).
