NT8D14 Universal Trunk card

Figure 198
RAN control signals (Control GRD = IDLE)

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.

Multi-Channel RAN modes

In Multi-Channel RAN, multiple RAN channels can be configured within
one RAN trunk route. In a Multi-Channel RAN route, each trunk has its
own dedicated RAN channel on a physical RAN machine. Multi-Channel
RAN routes do not support the cross connecting (daisy chains) of multiple
trunk ports together so that several callers hear the same RAN message.
