RAN modes of operation
Figure 196 "RAN control signals (Control GRD = IDLE)" (page 584) shows
the relationship of control signals to message playback for the operating
modes available in announcement machines. The signal names shown in
Figure 196 "RAN control signals (Control GRD = IDLE)" (page 584) are
typical.
Note 1: For continuous operation mode, connect the trunk unit MB line
to the announcer B line only, and ground the announcer ST+ line. For
pulse start or level start modes, connect the trunk unit MB line to the
announcer ST+ line only, and leave the announcer B line unconnected.
Note 2: A maximum of 24 universal trunk card units can be paralleled
to a single announcer channel.
