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.

For successful NET calling and response, the Address, Network, Member
Address, Link, Tune Time, LQA Exchange and Slot Width settings in the
NET List must be identical for all stations that are members of the NET.
Specifically, the order of the member stations in the Member Address
setting must be identical for all member stations, as this order is used to
determine the response slots for all stations.

The NET List
Settings in the NET List
NOTE
In the following discussion, you will need to log in as administrator to see
the NET List (see page 110, Logging into admin level from user level).
Name
The NET name may be any meaningful name that you want to assign to the NET. The
name may be up to 20 alphanumeric characters including spaces. The NET name is only
used for reference within the transceiver. It is not part of the NET configuration data.
Address
CAUTION
This setting must be the same in all member stations.
The Address setting contains the global address used by all members of the NET, and
other stations that have the NET programmed in the NET List, to establish an ALE link
during NET calls. The address may be up to 15 alphanumeric characters however, for
efficiency of NET calls, it is preferable that the address be limited to 3 characters. You
should choose an address that is not the same as any self addresses in the NET or wider
communication audience.
Network
CAUTION
This setting must be the same in all member stations.
The Network setting refers to the network containing the channels to be used with the
NET. This is selected from the pre-defined list of networks in the Network List. You can
set up two NETs with the same address but with different networks, say one for Group
Privacy Mode and one for Plain Privacy Mode. If the networks have the same channels,
then the Member Address setting in each NET should be identical.
Member Address
CAUTION
This setting must be the same in all member stations.
The Member Address setting contains a sequential list of the self addresses of all
members of the NET. The station uses this list to calculate the response slots, so each
station in the NET can determine when an automatic response is required after the
initiating call. A member address may be up to 15 alphanumeric characters however, for
efficiency of NET calls, it is preferable that the member addresses be limited to
3 characters. To preserve an empty slot use the null address (@@@) in a member
address position.
134
2110 SSB Transceiver Reference Manual
The NET List
Outgoing Calls
The Outgoing Calls setting enables you to set up your station to make calls to the NET,
or disable calling to the NET. Unless you need to restrict calling to the NET, you should
set the Outgoing Calls setting to Enabled for all stations in the NET, regardless of their
member status.
If you want to set up your NET so that only one station makes calls to the NET, set the
Outgoing Calls setting for the NET in that station to Enabled. All other stations with this
NET programmed would then have the Outgoing Calls setting for the NET set to
Disabled.
Incoming Calls
CAUTION
If the Link setting is set to Only if response, you must ensure that at least
one member station is set to receive an incoming call from the NET.
The Incoming Calls setting enables you to set up your station to receive all incoming
calls from the NET, receive calls only if you are a member of the NET, or disable
receiving calls from the NET.
If the station has the NET programmed, then it can receive calls from the NET if the
Incoming Calls setting is set to Enabled. If your station has the NET programmed but
you are not a member, and you do not want to receive all of the NET calls, set the
Incoming Calls setting to Members only. As your station is not a member of the NET, it
will not enter the link. If you are a member of the NET but do not want to receive any
calls from the NET, select Disabled.
Link
CAUTION
This setting must be the same in all member stations.
The Link setting determines how the initiating station links with the receiving stations. It
can link:
•
only if it receives a response from a member station
•
even if it doesn’t receive a response from a member station
•
immediately
NOTE
Stations with the NET programmed will only send a response to a NET
call if:
• their self address is included in the Member Address setting for the
NET, that is, they are a member of the NET
• the Response setting in the NET List is set to Send
2110 SSB Transceiver Reference Manual
135
The NET List
If it is important that you know with which member stations you have linked, then you
must set the Link setting to Only if response. The initiating station will make the call to
the NET using the best channel, on average, for all NET members. If there is no response
to this channel, the initiating station will select the next ranked channel and attempt the
call again, and so on until at least one response is received. Any member station
detecting the call will respond, if they are enabled to do so, then the initiating station
completes the link. Non-member stations with this NET programmed will also enter the
link, but as they are not members, they will not send a response. If you use this setting,
you must be sure that there are stations in your NET that will respond. If the initiating
station does not receive a response to the call after trying all channels for the NET, it will
terminate the link establishment process.
If you want to send a NET call to all stations with the NET programmed, but you do not
need to know which of the member stations have entered the link, set the Link setting to
Even if no response. The initiating station will make the call to the NET using the best
average channel for all NET members. All stations detecting the call will enter the link,
if enabled to do so.
If you want to send a NET call to all stations with the NET programmed without the
delay of the link establishment process, set the Link setting to Immediately. In this case,
the initiating station will establish an implicit link with any stations programmed with
the NET that detected the call. There is no 3-way handshake.
Response
CAUTION
If the Link setting is set to Only if response, you must ensure that at least
one member station is set to respond to a call from the NET.
The Response setting sets whether or not receiving member stations respond to NET
calls during link establishment. Generally, you would set the Response setting to Send,
so that there is confirmation of the station entering the link. However, if for some reason
you do not want the receiving station to transmit on air, you would set the Response
setting to Don’t send. If a station is set to not respond, it will still enter the link when it
receives the acknowledgement from the initiating station.
NOTE
The Response setting is only applicable to NET calls. It does not affect a
station’s ability to respond to an ANY, Group Selective or Wildcard call
(see page 158, Calls you can make and receive).
Tune Time
CAUTION
This setting must be the same in all member stations.
The Tune Time setting is the time that the members of the NET wait after the initiating
call before sending the automatic responses to the initiating station. This time should be
set to match the longest tuning time between all members in the NET.
136
2110 SSB Transceiver Reference Manual
The NET List
LQA Exchange
CAUTION
This setting must be the same in all member stations.
The LQA Exchange setting determines whether or not the exchange of LQA information
occurs during calls within the NET. If this setting is enabled, the transceiver adds an
appropriate amount of time to the slot widths so that LQA information can be exchanged.
Slot Width
CAUTION
This setting must be the same in all member stations.
The Slot Width setting determines the width of response slots for each member of the
NET. If the Slot Width setting is set to Fixed, then all slot widths match the width
required for the largest member address for the NET. However, this extends the time to
complete the handshake considerably. Unless required for interoperability reasons, the
recommended setting is Variable. In this case, the transceiver calculates the exact slot
width required for the response from each station.

For example, if the NET you renamed is used in an entry in the Address List, go to this
entry, find the reference to the old NET name, then change it so that the new name is
displayed (for help see page 155, Editing an entry in the Address List). If you do not
update the reference to the NET, the transceiver will prompt you to enter an address each
time you use the entry to make a call.

About phone links
A phone link is a connection to a station with a telephone interconnect unit that can route
Phone calls from transceivers to the public telephone network.
The addresses of the phone link stations you use, and the networks and channel/modes
you use to make Phone calls, can be stored in the Phone Link List. If you want to be
prompted for some of these details when you make a Phone call you can leave the
relevant settings in the Phone Link List blank. If you want to be prompted for all of these
details leave the Phone Link List blank.

About the Address List
The Address List is like any personal address book: it is a place to store the names and
addresses of stations you often call. When you have entered the details of a station,
calling the station becomes as simple as going to the entry for it, then pressing CALL.
If you want to be prompted to enter particular details at the time you make a call (for
example, type a message or select a channel) you can leave the relevant settings blank. If
you make several different types of calls to one address you can create several entries
with the same name and address but with different call types.
The Emergency 1 entry is stored in the Address List. This is the entry the transceiver
calls when you press . Setting up this key is covered on page 150, Setting up the
emergency key.
For information on making calls from the Address List and making calls using
page 173, Making a call.

The Address List
Settings in the Address List
CallType–Address
The call type is the type of call that you want to make to the station that you want to call.
For example, if you want to know where a mobile station is located, you send a Get
Position call to the station. The Address setting is the address of the station that you want
to call.
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Emergency, Message, Phone, Selective, and Send Position call
types. If you have the MIL-STD-188-141B ALE option installed, you can set up the
Address List to use the ALL, ANY, Group Selective, NET, and Wildcard address
syntaxes with the Emergency, Message, Phone, Selective, and Send Position call types.
The transceiver will automatically determine the call type from the ALE address syntax
that you enter in the address.
If you enter the ALE
address syntax...
The transceiver will send...
@?@
a global ALL call to all listening stations (see page 159, ALL
address syntax)
@A@
a selective ALL call to listening stations that have an ‘A’ as
the last character of their self address (‘A’ may be any
specified upper-case letter or number), for example, TNAA,
EANBA, 1NCA, 23A (see page 159, ALL address syntax)
@@?
a global ANY call to all listening stations (see page 160, ANY
address syntax)
@@A
a selective ANY call to listening stations that have an ‘A’ as
the last character of their self address (‘A’ may be any
specified upper-case letter or number), for example, TNAA,
EANBA, 1NCA, 23A (see page 160, ANY address syntax)
@AB
a double selective ANY call to listening stations that have
‘AB’ as the last two characters of their self address (‘A’ and
‘B’ may be any specified upper-case letter or number), for
example, BAAB, 14BAB, Q2CAB, 1AB (see page 160, ANY

matching the length of the sent address and with any uppercase letter or number as each of the characters, for example,
SAM, NAA, 234, 3AZ (see page 163, Wildcard address
syntax)
A?B? (example only)
a selective Wildcard call to listening stations that have a self
address matching the length of the sent address with ‘A’ and
‘B’ as the first and third characters respectively, and with any
upper-case letter or number in the second and last characters,
in this case (‘A’ and ‘B’ may be any specified upper-case
letter or number), for example, A2BM, ADB1, AZBE, A3B8
(see page 163, Wildcard address syntax)
Message
The Message setting in the Address List entry is available when you select Message as
the call type. It may be used for requesting configuration and diagnostic information
from other transceivers in your network, or you can pre-store a standard message that is
sent each time you make a call using this entry in the Address List. For example, you
may need to notify your base station that you are shutting down for the day. Therefore,
you would create an entry in your Address List to send a Message call (call type) to your
base station (address) containing the message ‘Shut down’. The Privacy Mode and
Privacy Password in the network used for the call specify how the data is transmitted, for
example, plain or encrypted (see page 124, Privacy Mode).
Messages are sent using a Codan protocol in Codan Selcall networks, and as an AMD
message in ALE/CALM networks.
A Message call closes the link as soon as the message has been sent.
Phone Link
The Phone Link setting in an Address List entry is available when you select Phone as
the call type. It identifies the phone link station through which the call is made.

receiving station. When AMD messaging is used in ALE calls, an emergency alert tone
is triggered by #HELP, #SOS, #MAYDAY, #PANPAN, and #EMERGENCY text. The
key can be set up to call one or more stations in an emergency.
You should pre-set all the settings in the Emergency entries so that the call
is made automatically during an emergency without the transceiver
prompting for information.

Calling several stations simultaneously
If you want to call several stations simultaneously, set up the Emergency 1 entry in the
Address List to make a call.
In an ALE/CALM network, calls to a group of stations can be made using ALL, ANY,
Group Selective, NET, and Wildcard address syntaxes through the Emergency, Message,
Phone, Selective, and Send Position call types if you have the MIL-STD-188-141B ALE
option installed. You can also send a message as part of the ALE call.
For more information on the special ALE address syntax see page 147, CallType–
Address.
In a Codan Selcall network, calls to a group of stations can be made using a group selcall
address through the Emergency, Message, and Selective call types. A group address is an
address that ends in two or more zeros. For example, to call all stations with addresses
that range from 1201 to 1299, you would enter 1200 as the address. To call all stations
with addresses that range from 150001 to 159999, you would enter 150000 as the
address.

Making several different types of calls
NOTE
This capability is available for use in Codan Selcall networks, enabling
you to make different types of calls, or even the same call type on several
channels.
In ALE/CALM networks, the channel selection is typically done
automatically, so it is not necessary to set up the Emergency entries in the
Address List to make chain calls.
If you want to make several different types of calls in succession you need to create an
entry in the Address List for each different type of call you want to make, and name the
entries Emergency 1, Emergency 2, Emergency 3 and so on.
When you press , the transceiver calls the station (or stations) specified in the
Emergency 1 entry, then pauses for about 10 seconds. It then calls the station in the
Emergency 2 entry, and so on, until it calls the station in the last Emergency entry. Calls
made this way are referred to as chain calls.
When the transceiver pauses between calls it displays the seconds remaining in the pause
at the top right of the screen, as shown in Figure 29.
Figure 29:
The front panel screen during a chain call
You can terminate a chain call by pressing PTT. If you press PTT during:
•
an Emergency or Selective call, you can continue with the current call but the chain
call itself is terminated (that is, the transceiver will not call the next Emergency
entry)
•
a call in which data is being sent to another station (for example, a Message call), the
current call and chain call are terminated
NOTE
If you want to make a call that sends data and a call that enables you to
speak to an operator, set up the Emergency entries to make the data call
first: once you press PTT to speak to an operator, the chain call is
terminated.
You can also terminate a chain call by pressing any key. The exceptions to this are that:
152
•
you can press
to remove messages on the screen, and press
the volume at any time, without terminating the call
and
to adjust
•
if you are prompted to select and/or enter details about the call (for example, a
channel/mode), you can press any keys to do so without terminating the call
2110 SSB Transceiver Reference Manual
The Address List
To set up the
key to call several stations in succession:
Decide on the stations you want to call in an emergency, the type of call you want to
make to each station, and the order in which you want to make the calls.
NOTE
If you want to use a special ALE address syntax, you should set up
the Emergency entries to make calls that create an implicit link, or
link immediately first, for example, an ALL call. Address syntaxes
that require a response should be set up in the last Emergency entry
of the chain call, if required.
Enter the details of the first call you want to make into the Emergency 1 entry (for
help see page 155, Editing an entry in the Address List).
Create an entry in the Address List, name it Emergency 2 and enter the details of the
second call you want to make (for help see page 154, Creating an entry in the
Address List).
Create an entry for each subsequent call you want to make, naming the entries
Emergency 3, Emergency 4 and so on.

Special ALE address syntaxes
There are five types of special address syntax available for use in ALE/CALM networks
with a 2110 SSB Transceiver:
•
ALL address syntax (FED-STD-1045 ALE/CALM option or MIL-STD-188-141B
ALE option)
•
ANY address syntax (MIL-STD-188-141B ALE option)
•
Group Selective address syntax (MIL-STD-188-141B ALE option)
•
NET address syntax (MIL-STD-188-141B ALE option)
•
Wildcard address syntax (MIL-STD-188-141B ALE option)
The types of ALE address syntaxes you can use depends on the options installed in the
transceiver.
Each address syntax has an icon associated with it that is displayed when you make and
receive calls (see Table 17).
Table 17: Call icons for Selective calls made or received using a special ALE
address syntax

2110 SSB Transceiver Reference Manual
Making and receiving calls
ALL address syntax
NOTE
The ALL address syntax may be used if the FED-STD-1045 ALE/CALM
option or MIL-STD-188-141B ALE option is installed in the transceiver.
NOTE
You cannot use the ALL address syntax in the Channel Test, Get Position,
or Get Status call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
If you want to send an ALE call to any station that is tuned to the same frequency in an
ALE/CALM network or scanning the network, make a call through the Emergency,
Message, Phone, Selective, and Send Position call types using the ALL address syntax
(see page 167, Emergency call, page 168, Message call, page 169, Phone call, page 169,
Selective call, and page 170, Send Position call). The ALL call does not specifically call
any stations, and does not request any automatic responses from stations that enter the
link. Stations can be configured to accept or to ignore ALL calls.
NOTE
When you use an ALL address syntax through the Selective call type, the
call icon will change to the ALL call icon ( ) when the call is started.
The global ALL address syntax is @?@. All stations detecting the call will enter an ALE
link with the initiating station, if enabled to do so. The group of linking stations can be
narrowed by using a selective ALL address syntax. In this address, the ? is replaced by
an upper-case letter or number, for example, @A@. All stations detecting the call that
have this letter or number as the last character in their self address for the ALE/CALM
network will enter the link.
If you send a selective ALL call to a group of stations, you can send another selective
ALL call to bring more stations into the link. For example, if you initially call @A@, all
stations tuned to the same frequency in an ALE/CALM network or scanning the network
with an ‘A’ as the last character of their self address will enter the link. If you follow this
with a call to @B@, then a further group of stations with ‘B’ as the last character of their
self address will also enter the link. If the receiving stations are already in a link, this link
will be closed and a new link created with the new call.
Alternatively, you can send multiple ALL addresses together to make a call to a range of
stations, for example, @A@,@B@.
2110 SSB Transceiver Reference Manual
159
Making and receiving calls
ANY address syntax
NOTE
The ANY address syntax may be used if the MIL-STD-188-141B ALE
option is installed in the transceiver.
NOTE
You cannot use the ANY address syntax in the Channel Test, Get Position,
or Get Status call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
CAUTION
If a station detects an ANY call to its matching self address, it will send a
response over the air.
If you want to send an ALE call to any station that is tuned to the same frequency in an
ALE/CALM network or scanning the network, and receive a response, make a call
through the Emergency, Message, Phone, Selective, and Send Position call types using
the ANY address syntax (see page 167, Emergency call, page 168, Message call,
page 169, Phone call, page 169, Selective call, and page 170, Send Position call). The
ANY call does not specifically call any stations, but it does request an automatic
response from stations that detect the call. These responses are returned in any slot
position (collisions may occur). The operator at the initiating station can use these
responses to gather information on the status of the stations using the network. The
initiating station then completes the link establishment with an acknowledgement sent to
all stations from which it received a response. Stations can be configured to respond to or
to ignore ANY calls.
NOTE
When you use an ANY address syntax through the Selective call type, the
call icon will change to the ANY call icon ( ) when the call is started.
The global ANY address syntax is @@?. All stations detecting the call will send a
response to the initiating station. The group of stations detecting the call can be narrowed
by using a selective ANY address syntax. In this address, the ? is replaced by an uppercase letter or number, for example, @@A. All stations detecting the call that have this
letter or number as the last character in their self address for the ALE/CALM network
will send a response, then enter a link with the initiating station when the
acknowledgement is received.
You can send multiple ANY addresses together to make a call to a range of stations, for
example, @@A,@@B.
The allowable length of the called address is dependent on the length of the self address
used for the call.
160
If the length of your self address is...
The length of the called address can be...
1–3 characters
1–9 characters
4–6 characters
1–3 characters
2110 SSB Transceiver Reference Manual
Making and receiving calls
Group Selective address syntax
NOTE
The Group Selective address syntax may be used if the MIL-STD-188141B ALE option is installed in the transceiver.
NOTE
You cannot use the Group Selective address syntax in the Get Position or
Get Status call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
CAUTION
If a station detects a Group Selective call to its matching self address, it
will send a response over the air.
If you want to send an ALE call to specific stations that are named in the call but are not
members of a pre-determined group, make a call through the Emergency, Message,
Phone, Selective, and Send Position call types using the Group Selective address syntax
(see page 167, Emergency call, page 168, Message call, page 169, Phone call, page 169,
Selective call, and page 170, Send Position call). The Group Selective call requests an
automatic response from stations that detect the call and whose self addresses match one
of those in the call. These responses are sent in reverse order from that provided in the
call. The initiating station then completes the link establishment with an
acknowledgement sent to all stations from which it received a response.
NOTE
When you use a Group Selective address syntax through the Selective call
type, the call icon will change to the Group Selective call icon ( ) when
the call is started.
With Group Selective addresses, the length of the combined address can be no longer
than 12 ALE words, excluding commas. An ALE word has 3 characters. There can be no
more than five different first ALE words in the combined address. For example:
An address of ‘BOB1,BOB2,BOB3,BOB4,TIM,JOHN,MIK,SUE’ has five different first
ALE words, that is, BOB, TIM, JOH, MIK and SUE. However, this address will be
rejected because it has a total of 13 ALE words, that is, BOB, 1, BOB, 2, BOB, 3, BOB,
4, TIM, JOH, N, MIK and SUE.
2110 SSB Transceiver Reference Manual
161
Making and receiving calls
NET address syntax
NOTE
The NET address syntax may be used if the MIL-STD-188-141B ALE
option is installed in the transceiver.
NOTE
You cannot use the NET address syntax in the Get Position or Get Status
call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
If you want to send an ALE call from one station to other stations that are members of
the NET or have the NET programmed, make a NET call using the NET address through
the Emergency, Message, NET, Phone, Selective, and Send Position call types (see
page 167, Emergency call, page 168, Message call, page 169, Phone call, page 169,
Selective call, and page 170, Send Position call). These stations have a common NET
address. The member stations send an automatic response to the initiating station in a
pre-determined response slot. The initiating station then completes the link establishment
with all member stations. If a member station is set up to not respond during its allocated
response slot, it will still enter the link.
NOTE
When you use a NET address syntax through the Selective call type, the
call icon will change to the NET call icon ( ) when the call is started.
The NET address syntax can be any combination of upper-case letters and numbers up to
15 characters however, for efficiency of NET calls, it is preferable that the address be
limited to 3 characters. To make a call using a NET, the NET must be programmed in the
transceiver and configured correctly (see page 138, Programming the NET List).
162
2110 SSB Transceiver Reference Manual
Making and receiving calls
Wildcard address syntax
NOTE
The Wildcard address syntax may be used if the MIL-STD-188-141B
ALE option is installed in the transceiver.
NOTE
You cannot use the Wildcard address syntax in the Channel Test, Get
Position, or Get Status call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
CAUTION
If a station detects a Wildcard call to its matching self address, it will send
a response over the air.
If you want to send an ALE call to any station that is tuned to the same frequency in an
ALE/CALM network or scanning the network, and receive a response, make a call
through the Emergency, Message, Phone, Selective, and Send Position call types using
the Wildcard address syntax (see page 167, Emergency call, page 168, Message call,
page 169, Phone call, page 169, Selective call, and page 170, Send Position call). The
Wildcard address syntax, which ALE stations recognise, uses the wildcard character ? as
a placeholder for characters within a self address of a receiving station. Stations that
detect the call and whose self address matches the pattern in the wildcard address will
send a response to the initiating station. These responses are returned in any slot position
(collisions may occur). For example, a call sent to EM? may be responded to by stations
in the network with a self address in the ranges EMA–EMZ and EM0–EM9. The
initiating station then completes the link establishment with an acknowledgement sent to
all stations from which it received a response.
NOTE
When you use a Wildcard address syntax through the Selective call type,
the call icon will change to the Wildcard call icon ( ) when the call is
started.
NOTE
The wildcard question marks can be in any position within the address.
The stations that respond will have an address that is the same length as
the wildcard address sent from the initiating station.
You can send multiple Wildcard addresses together to make a call to a range of stations,
for example, ?A,B??.
The allowable length of the called address is dependent on the length of the self address
used for the call.
If the length of your self address is...
The length of the called address can be...
1–3 characters
1–9 characters
4–6 characters

address syntax...
The transceiver will send...
@A?
a double selective wildcard ANY call to listening stations
that have an ‘A’ as the second to last character of their self
address (‘A’ may be any specified upper-case letter or
number) and any upper-case letter or number as the last
character, for example, USAM, 19MA0, ENA9, 3DAZ (see
page 160, ANY address syntax)
ABC,JK3MN,PQR
(example only)
a Group Selective call to the stations specifically addressed
(see page 161, Group Selective address syntax)
NET address

a Wildcard call to listening stations that have a self address
matching the length of the sent address and with any uppercase letter or number as each of the characters, for example,
SAM, NAA, 234, 3AZ (see page 163, Wildcard address
syntax)
A?B? (example only)
a selective Wildcard call to listening stations that have a self
address matching the length of the sent address with ‘A’ and
‘B’ as the first and third characters respectively, and with any

in this case (‘A’ and ‘B’ may be any specified upper-case
letter or number), for example, A2BM, ADB1, AZBE, A3B8
(see page 163, Wildcard address syntax)
Call types
There are 8 different types of calls available with an 2110 SSB Transceiver:
•
Channel Test call
•
Emergency call
•
Get Position call
•
Get Status call
•
Message call
•
Phone call
•
Selective call
•
Send Position call
The types of calls you can make and receive depend on the options installed in the
transceiver.
Each call type has an icon associated with it that is displayed when you make and receive
calls (see Table 18).

Each type of call is described below.
Channel Test call
If you want to test the suitability of a channel/mode before you use it to transmit voice or
data, make a Channel Test call.
In an ALE/CALM network, a Channel Test call may be sent to an ALE address using a
Group Selective or NET address syntax (if you have the MIL-STD-188-141B ALE
option installed).
NOTE
You cannot use the ALL, ANY, or Wildcard address syntax with a
Channel Test call.
A Channel Test call made in an ALE/CALM network with a Group Selective or NET
address may be used to replace the information in the LQA database. The initiating
station automatically sends a beacon on each channel/mode combination in the ALE/
CALM network, recording local and remote BER and SINAD information, and
calculating an LQA score. The LQA screen is visible during the Channel Test call, and at
the end of the call, displays the best channel on which to make the call.
The LQA information recorded during a Channel Test call in an ALE/CALM network
replaces information already recorded against the same network and self addresses.
Using a Channel Test call in an ALE/CALM network is an immediate method of
replacing the LQA database in the transceiver.
A Channel Test call made in an ALE/CALM network using the text SOUNDING as the
call address may be used to initiate a sounding operation. Transceivers that detect this
sounding will update the relevant information stored in their LQA database.
166
2110 SSB Transceiver Reference Manual
Making and receiving calls
In a Codan Selcall network, a Channel Test call sends a request to the station you want to
call on the channel/mode you have selected. The receiving station automatically returns
an audible test signal. The volume and clarity of this signal indicates the quality of the
channel/mode.
You can also test channels once you have started a call (for more information see
page 176, Replacing LQA information as part of a call in an ALE/CALM network and
page 174, Testing a channel as part of a call in a Codan Selcall network).
Emergency call
If you want to trigger an emergency alert tone at a particular station and speak to an
operator, make an Emergency call. If the GPS option is installed in the transceiver (and
you have connected and configured a GPS receiver), your GPS position is automatically
sent with the call. Emergency calls can be sent to several stations at once (see page 150,
Setting up the emergency key and page 170, Group calls in a Codan Selcall network).
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Emergency call type to send a call to a group of stations using an
ALE/CALM network. If you have the MIL-STD-188-141B ALE option installed, you
can use the ALL, ANY, Group Selective, NET, and Wildcard address syntaxes with the
Emergency call type to send a call to a group of stations using an ALE/CALM network.
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
For more information on the ALE address syntaxes you can use with an Emergency call
see page 164, Summary of the special ALE address syntaxes.
Get Position call
NOTE
You cannot use the ALL, ANY, Group Selective, NET, or Wildcard
address syntax with a Get Position call.
NOTE
The success of your Get Position call will depend upon the setting in the
Cfg Respond GPS entry in the Control List of the transceiver you are
polling and the Privacy Mode of the network you are using for the call
(see page 204, Cfg Respond GPS).
If you want to obtain the GPS position of a station that has the GPS option installed in
the transceiver (and a GPS receiver connected to it and configured), make a Get Position
call. Get Position calls are automatically answered by the receiving station so an operator
is not required to take any action.
The information you receive from a Get Position call is displayed on the front panel as it
is received, if permitted, and is stored in the Calls In Log (see page 192, The Calls In
Log).
2110 SSB Transceiver Reference Manual
167
Making and receiving calls
Get Status call
NOTE
You cannot use the ALL, ANY, Group Selective, NET, or Wildcard
address syntax with a Get Status call.
NOTE
The success of your Get Status call will depend upon the setting in the
Cfg Respond OTA entry in the Control List of the transceiver you are
polling and the Privacy Mode of the network you are using for the call
(see page 204, Cfg Respond OTA).
If you want to obtain information on the status of a transceiver at another station, such as
the power output of the transmitter or the firmware versions installed, make a Get Status
call. Get Status calls are automatically answered by the receiving station so an operator is
not required to take any action.
The information you receive from a Get Status call is displayed on the front panel as it is
received, if permitted, and is stored in the Calls In Log (see page 192, The Calls In Log).
When you make a Get Status call you need to specify the type of information you
require: diagnostic or configuration. This is described in detail on page 335, Get Status
calls.
Message call
If you want to send a typed message to another station, make a Message call. You can
enter a message at the time you make a call, store up to 10 messages in the Control List
for later use, and store messages in the Address List as part of a Message call.
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Message call type to send a call to a group of stations using an
ALE/CALM network. If you have the MIL-STD-188-141B ALE option installed, you
can use the ALL, ANY, Group Selective, NET, and Wildcard address syntaxes with the
Message call type to send a call to a group of stations using an ALE/CALM network.
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
For more information on the ALE address syntaxes you can use with a Message call see
page 164, Summary of the special ALE address syntaxes.
Message calls are automatically answered by any receiving stations so an operator is not
required to take any action. If you send an ALE call using the Message call type, the link
terminates immediately after the message is sent. Messages you receive are displayed on
the front panel, if permitted, and stored in the Calls In Log (see page 192, The Calls In
Log).
168
2110 SSB Transceiver Reference Manual
Making and receiving calls
Phone call
If you want to call a telephone number from the transceiver, make a Phone call. Before
you make a Phone call you need to know the address of a telecommunication station
through which your call can be routed to the public telephone network.
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Phone call type to send a call to a group of telecommunication
stations using an ALE/CALM network. If you have the MIL-STD-188-141B ALE option
installed, you can use the ALL, ANY, Group Selective, NET, and Wildcard address
syntaxes with the Phone call type to send a call to a group of stations using an ALE/
CALM network.
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
For more information on the ALE address syntaxes you can use with a Phone call see
page 164, Summary of the special ALE address syntaxes.
Selective call
If you want to speak to an operator at a particular station, make a Selective call. When
the station receives the call the transceiver rings like a phone to notify the operator.
Selective calls can be heard by any station tuned to or scanning your current channel
with their mute switched off. However, only the transceiver at the station to which the
call has been addressed will ring.
Selective calls can be made to several stations at once (see page 170, Group calls in a
Codan Selcall network).
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Selective call type to send a call to a group of stations using an
ALE/CALM network. If you have the MIL-STD-188-141B ALE option installed, you
can use the ALL, ANY, Group Selective, NET, and Wildcard address syntaxes with the
Selective call type to send a call to a group of stations using an ALE/CALM network.
The transceiver will automatically determine the call icon from the address syntax that
you enter in the address.
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
If you have the MIL-STD-188-141B ALE option installed and the ALE Selective Msg
entry in the Control List enabled, you will be able to send a message with the start of a
call if you press when prompted during the call. You must use an ALE/CALM
network to make the call.
For more information on the ALE address syntaxes you can use with a Selective call see
page 164, Summary of the special ALE address syntaxes.
2110 SSB Transceiver Reference Manual
169
Making and receiving calls
Send Position call
If you want to send your GPS information to another station, make a Send Position call.
You can only make Send Position calls if the GPS option has been installed in your
transceiver.
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Send Position call type to send a call to a group of stations using
an ALE/CALM network. If you have the MIL-STD-188-141B ALE option installed, you
can use the ALL, ANY, Group Selective, NET, and Wildcard address syntaxes with the
Send Position call type to send a call to a group of stations using an ALE/CALM
network. The transceiver will automatically determine the call icon from the address
syntax that you enter in the address.
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
For more information on the ALE address syntaxes you can use with a Send Position call
see page 164, Summary of the special ALE address syntaxes.
Send Position calls are automatically answered by any receiving stations so an operator
is not required to take any action. If you send an ALE call using the Send Position call
type, the link terminates immediately after the GPS position is sent. GPS positions you
send are stored in the Calls Out Log (see page 187, The Calls Out Log).
Group calls in a Codan Selcall network
Emergency, Message and Selective calls can be made to a group of stations
simultaneously by using a Codan Selcall network and a group address.
A group selcall address is an address that ends in two or more zeros. For example, to call
all stations with addresses that range from 1201 to 1299, you would enter 1200 as the
address. To call all stations with addresses that range from 150001 to 159999, you would
enter 150000 as the address.
NOTE
170
You can replace the zeros at the end of the address with dots or question
marks, for example, 12.. or 12?? instead of 1200.

Special AMD messaging features
NOTE
Special AMD messaging is available if the MIL-STD-188-141B ALE
option is installed.
For interoperability with other transceivers, the 2110 SSB Transceiver recognises special
AMD messaging syntax included at the beginning of an AMD message sent on a
network with a Privacy Mode of Plain. The transceiver will accept and process the
syntax shown in Table 19. You can also manually enter any of this text into an AMD
