Other Command Specifics
The bulk of the communications used for the switcher/DPM interface is via
parametric interchange, as indicated in Appendix B. This section tabulates
other commands used by the switcher/DPM interface.
Currently, the only other communications is the exchange of an on line
event while communications are initiated. The DPM must transmit an on-
