Barrett Selective Calling System General In addition to the use of the transceiver in simple voice mode to call other stations there are several different types of Selective Calling systems available. The calling systems available for the Barrett PRC-2090 transceiver are listed below:International A four and six digit Selective Call system, fully interoperable with the UN format published in September 2004 and fully backwards compatible with all previous Barrett 4 digit Selcall protocols.
Selective Call –“Selcall” Selcall is a digital signalling system based on standard CCIR-493 for use on HF networks. Each station in an HF network can be assigned up to 10 self IDs of which there can be a mixture of four or six digit IDs (identification). The station can be called using any of these self IDs.
More Selective Calling Information Selcall Self IDs As from software version 2.00 the 2050 transceiver can have up to 10 selcall self IDs assigned to it. These Selcall IDs can be any combination of 4 or 6 digit OEM or International type id. Selcall Decode As from software version 2.00 the 2050 transceiver has the ability to decode both OEM and International Selcalls on any channel programmed as a Selcall channel.
Default Self IDs Default self IDs are the IDs used when making a selective call. They are used when the self ID is not set during the call procedure or the Selcall address book entry being used does not have a self ID attached to it. These IDs are also used when making calls via the RS232 control command set. Setting Default Self IDs then press the key. Use the scroll keys to select the self id to attach to the default ID (in this case the 4 digit OEM defalut ID) then press the key.
Detaching an ID From the Default Self IDs Detaching an ID from the default IDs will force the operator to select a self ID when making a Selcall. then press the press the key. key until the “Detach Self ID?) screen appears. Use the scroll keys to select the option required.
then press the 34 of 285 key.
Contacting Another Station - Using Selective Call “Selcall” and Telcall Entering Station IDs and Using the Address and Telephone Books Selcall and Telcall functions described in this section require station IDs or telephone numbers to be entered when making a call. They make use of convenient address and telephone books to allow frequently used Station IDs, station names and telephone numbers to be easily entered.
then press the or 36 of 285 press the key key and the last station called will be called again.
Changing Self IDs During a Call During any selective call process pressing the button after the destination address has been entered will continue on with the call process. If the button is pressed and held for 2 seconds then the option of changing the self ID of the call will become available. If the destination address is a fixed address entry then the operator cannot change self IDs during the call.
Use the scroll keys to scroll to a non fixed address book entry. press and hold the key for 2 seconds Use the scroll keys to select the new self ID to be transmitted then press the 38 of 285 key to continue the call process.
Station ID ranges 4 and six digit networks are all accommodated in the PRC-2090 standard Selcall system Station ID range from 000000 to 999999 inclusive (the destination ID must be either 4 or 6 digits long) Calling groups In four digit format All call A station sending X000 will be received by stations X000 - X999 (up to 890 stations*) Group call A station sending XX00 will be received by stations XX00 - XX99 (up to 89 stations*) Sub-group call A station sending XXX0 will be received by stations XXX0 -
When Asked to Enter a Telephone Number:Either enter the telephone number using the numeric keypad (a number up to 16 digits) or if you think that telephone number is in the phone book use the Scroll keys to find the name and number you want to call:- or if you know the name associated with the telephone number in the phone book press the key and either enter the first letter of the name you want to call using the alpha keypad and use the Scroll keys or use the Scroll keys to find the name you want to c
Checking for the Best Channel to Use Between Two Stations - Beacon Call Before using many of the Selcall and Telcall functions in this section it is useful to know how to use the “Beacon Call” function. "Beacon Call" allows the operator to determine the signal quality between their station and a station they want to call on a particular channel, but without actually alerting the station they are doing so.
Receiving a Beacon Call When a transceiver receives a beacon request call, it responds by transmitting the Beacon Call revertive tones. No indications occur on the transceiver. Beacon Calls are not saved in the Selcall history buffer. Sending a Selcall select the channel you want to send the Selcall on.
Receiving a Selcall To receive a Selcall your transceiver must be programmed for Selective Call (Selcall) and where multiple channels are in use the scan function should be activated.
Receiving All Calls, Group Calls and Sub-group Calls Stations can send a Selective Call that will alert different groupings of mobiles as follows:In four digit format All call A station sending X000 will be received by stations X000 - X999 (up to 890 stations*) Group call A station sending XX00 will be received by stations XX00 - XX99 (up to 89 stations*) Sub-group call A station sending XXX0 will be received by stations XXX0 - XXX9 (up to 9 stations*) In six digit format All call A station sending XXX
Receiving an “All call ” , “Group Call”, “Sub-Group Call” When you receive any of the calls above an audible alarm is sounded, the mute (squelch) (if selected) opens and the display shows the call type as follows:“All call” “Group call” “Sub-group call” In all group calls the audible alarm will sound for thirty seconds and then time out. To cancel the alarm before the time out and to acknowledge the call press PTT or any key.
Emergency Calls Receiving an Emergency Call Barrett transceivers that receive an emergency Selcall emit a distinctive audio alarm and display the following:- If the transceiver sending the emergency Selcall is fitted with a GPS receiver the position will also be displayed as illustrated below :- If the transceiver sending the emergency Selcall was not fitted with GPS or no data is available the following is displayed:- 46 of 285
Direct Dial Telephone Calls - Telcalls Transceivers equipped with the Telcall option can direct dial telephone numbers and receive calls from telephone users through a Barrett telephone interconnect base stations. Note:- If ALE is in use refer to the ALE section for details. Making a Direct Dial Telephone Call - Sending a Telcall select the channel you want to send the Telcall on. (“Beacon Call” can be used to select the best channel) listen for traffic on that channel, if no traffic is heard then continue.
then press the key enter the telephone number you want to call (see “Entering station IDs and using the address and telephone books”) then press the key wait for the Telcall to be sent. listen for revertive tone from the called station that indicates the call was successful. If no revertive call is heard try another channel and repeat the process. When the call is successful wait for telephone connection to be made and proceed with call..
Hang Up Call When a call to a telephone interconnect base station has been completed the caller should "hang up" by sending a “hang up” code:- press the key select “Hang up” with the scroll keys then press the key select the ID of the telephone interconnect that you are connected through then press the key When the hang up Selcall has completed transmitting, listen for hang up revertive signal, confirming the “hang up” was successful, if not heard repeat the above procedure.
Preset/Predialled (Abbreviated Number) Telephone Calls A base station equipped with telephone interconnect facilities is also capable of making preset (abbreviated number) telephone calls, these calls are also known as predialled calls. Preset (abbreviated) telephone numbers are stored in the telephone interconnect unit and are accessed by sending a standard Selcall using a specific Selcall number. select the channel you want to send the “hang up” call on.
Preset (Abbreviated) Selcall Numbering Enter xxxxAA or xxAA where xxxx or xx is the (four) six or (two) four digit Selcall ID of the base station equipped with telephone interconnect facilities and AA represents the preset telephone number (between 1 and 98) Example:Entering 4523 will instruct a telephone interconnected base station with a four digit Selcall ID of 45XX to call preset (abbreviated) number stored as 23 in the telephone interconnect.
Fixed and Preset Address Book Entries Fixed Address Book Entry Address book entries can be programmed to be fixed to certain self IDs via the 2000 Series Programming Software. This stops the transceiver operator from being able to select which self ID is to be used when calling a specific address book entry. In other words the self ID attached to the address book entry will always be used and can only be changed via the 2000 Series Programming Software.
Preset Address Book Entry Preset or predialled address book entries are used when the destination transceiver is connected to a telephone interconnect which has preset facilities available. Preset address book entries are fixed and can only be changed via the 2000 Series Programming Software. This means that the operator only needs to know which preset number (01 to 98) has the required phone number set.
Call History Whenever a Selcall, Telcall, All call, Group call, Sub group call, Pagecall, Statcall GPS or Emergency call is received or transmitted its details are held in a first in first out call history buffer. Received calls that have not been viewed before are held in a section called “New Calls”, received calls that have been viewed are held for future viewing in the “Call inbox” all transmitted calls are stored in the “Call Outbox”. Each history buffer can store up to 30 entries.
Hold the key until the “Erase Entry” screen is shown. press the key and the entry will be deleted. To delete all entries from a Selcall history section scroll to the “All Entries” screen then press the key.
Scanning Channels Scanning allows a HF transceiver to monitor several channels for incoming calls. It is particularly useful as the nature of HF signal propagation means that not all channels are available for communications at one time. For instance, a station calling a station that is in scanning can send a “Beacon Call” on any channel knowing the station it is calling is monitoring all its available channels.
Selecting a Scan Table press the key for more than two seconds use the scroll keys to select the scan table number then press the key Note:- If no scan tables are programmed the following is displayed:- Initiating Scan Momentarily press the key. Alternatively scan may be programmed as a default condition so when the transceiver is switched on, scan is automatically initiated, or after a period of inactivity, i.e. no key presses, the transceiver returns to scan.
Clarifier The clarifier is used to finely tune the receiver on the selected channel to compensate for received signals from other stations that are off frequency. The receiver can be tuned in the clarifier mode in steps of 1 Hz to frequencies up to -1 kHz and +1 kHz of the assigned channel frequency, depending on programming. (see note below) to enter clarifier tune mode.
Noise Reduction Selection The DSP noise reduction system is enabled and disabled by momentary pressing the key. When the noise reduction system is selected the display shows a small square to the right of the mode indication notated NR as below:- The DSP noise reduction system is disabled by momentary pressing the key. Note:- There are three levels of noise reduction available, these levels can be set either when programming the transceiver or in the “Audio Settings” section of the protected menu.
Mute (Squelch) Selection There are three mute (squelch) modes:Audio (syllabic) Mute (Squelch) – the receiver audio is enabled when speech is detected on the selected channel. Note:- The syllabic mute sensitivity can be set to three levels, these levels can be set either when programming the transceiver or in the “Mute Settings” section of the protected menu.
Mode Selection The mode key changes the mode of operation - LSB, USB, AM, CW or AFSK of the selected channel. The mode key will only temporarily set the mode for a selected channel, the mode reverting to that channel’s programmed mode after the channel is changed, or the transceiver is turned off. Press the key repeatedly to select the required mode:- Note:- If the IF filter option is physically fitted and enabled in software, it will automatically be selected when CW and AFSK mode is selected.
Advanced Selective Call Functions Requesting Another Station’s GPS Position select the channel you want to send the GPS request call on.
Wait for the station you called to send back its position data after which the following will be displayed:The station called GPS position:- or – the following error messages:- The GPS unit is not providing data to the remote transceiver There is no GPS receiver fitted to the remote transceiver There was no response from the remote station 63 of 285
Sending Your GPS Position to Another Station select the channel you want to send the GPS call on. (“Beacon Call” can be used to select the best channel) listen for traffic on that channel, if no traffic is heard then continue.
Note:- If the display indicates that the GPS is unavailable as shown below you cannot select the Selective Call function “GPS data.
Text Messaging – “Pagecall”, “SMS” Pagecall allows messages of up to 32 characters in International format or 64 characters in OEM format to be sent or received to and from other transceivers with Pagecall facilities. Sending a “Pagecall” “SMS” select the channel you want to send the Pagecall on. (“Beacon Call” can be used to select the best channel) listen for traffic on that channel, if no traffic is heard then continue.
then press the key type in your messages using the alpha numeric keys then press the key 67 of 285
Receiving a “Pagecall” “SMS” When a Pagecall is received an audible alarm is sounded, the mute (squelch) is opened and the display shows the following:- The audible alarm will sound for thirty seconds and then time out. To cancel the alarm before the time out period and to acknowledge the call, press PTT or any key. When the audible alarm times out the call received “Envelope” icon is displayed in the bottom right hand side of the display.
Special Characters in a Pagecall As from V2.00 of transceiver firmware “Pagecall” selective call messages have the ability to send special characters out as part of the message. These special characters are ‘*’, ‘#’ and ‘.’. To get the new characters to display properly the transceiver front panel unit needs to be fitted with V14 or later firmware.
To select a ‘.’ character press the key. To select either the ‘*’ or ‘#’ character the transceiver needs to go into ‘Special Character Mode’. To do this press the key. Please note that if V14 or later front panel firmware is not fitted then a ‘?’ will be shown in place of the ‘#’. Use the up/down scroll keys to select the character required. Pressing the key again will exit the ‘Special Characters Mode’ without saving the character to the message.
Remote Station Operational Status – “Statcall” “Statcall” allows the operational status parameters of any Barrett transceiver fitted with Selcall to be accessed. This status is sent from the remote transceiver as a Selcall with the status information embedded within the Selcall structure.
The status request is being transmitted Your station is waiting for the station you called to send back its “Status data” (which sounds like the remote station sending a Selcall to you) after which the following will be displayed, use the or keys to move through the pages:- or – the following error messages:- There was no response from the station you requested the status from, repeat the process or change the channel and repeat the process 72 of 285
Person to Person(s) Secure Call This facility allows a secure voice connection to be made between two or more stations. Note:- In the protected menu “Audio Setting” section, scrambler must be enabled in the “Scrambler section” and in the “Scrambler code” section a 4 digit number entered. For security purposes this code must be the same as the code set in the station you wish to call. select the channel you want to set up the secure link on.
Tuning the Receiver The PRC-2090 transceiver can be used as a tunable receiver. The receiver can be tuned from 500 kHz to 30 MHz in steps ranging from 1 Hz up to 10 MHz. Press the key to enter the tuning receiver mode:- To tune the receiver move the cursor over the digit representing the frequency increment required in the receiver frequency display you wish to tune using either the keys, then use.
