176 ENVOY™ TRANSCEIVER REFERENCE MANUAL
Overview of NETs
NOTE: NET calling is available if the MIL-STD-188-141B ALE option is
installed.
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 NET
Members entry for the NET, respond in their designated response slot. If a
transceiver has the NET programmed, but its address is not in the list of NET
members, it can still receive communications from the NET. In the Envoy™
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 calling station, a
response from the called station, and an acknowledgement from the calling station.
Following the acknowledgement, all stations that are able to, enter the link.
A station can have a NET programmed in its profile and either:
• be a member of the NET, that is, their self address is in the NET Members
entry for the NET, or
• not be a member of the NET, that is, their self address is not in the NET
Members entry for the NET
NETs are used with an ALE/CALM HF network. This defines the channels that may
be used when establishing the ALE link, and the privacy mode for messaging within
a call.
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 a
contact to make a NET call.
Figure 46 shows the information that is stored for a NET. Each item is described in
detail in the sections following.
