About NETs
A NET is a special ALE addressing capability. With NET addressing, two or more
stations are pre-configured to respond to the same NET address. When a station calls a
NET, all stations with that NET address and their self addresses in the Member Address
setting for the NET respond in their designated response slot. In the NGT transceiver, a
NET contains the configuration information required for making and receiving NET
calls. This information defines the process for the handshake during link establishment.
The full 3-way handshake process involves a leading call from the initiating station, a
response from the receiving station, and an acknowledgement from the initiating station.
Following the acknowledgement, all stations that are able to, enter the link.
A station can have a NET programmed in its NET List and either:
• be a member of the NET, that is, their self address is in the Member Address setting
for the NET
• not be a member of the NET, that is, their self address is not in the Member Address
setting for the NET
NETs are used with ALE/CALM networks, which define the channels that the NET may
use when establishing an ALE link, and the Privacy Mode for messaging within a call.
For more information on networks see page 121, The Network List.
You can make a call to a NET by selecting the NET, Emergency, Message, Phone,
Selective, or Send Position call type and entering the NET address. You can set up an
entry in the Address List to make a NET call. For more information on the Address List
see page 145, The Address List.
Figure 28 shows an example of the information required to create a NET. This
information is explained on page 134, Settings in the NET List.
