1111STR”01912243174”,”01912241558”,”07771234567”
Remember an optional ? can be included at the end of the message to receive conrmation of the stored numbers, like so:
1111STR”01912243174”,”01912241558”,”07771234567”,”01912241559”,”07897123456”?
The following reply will be received from the GSM:
MEM OPEN 003 = 01912243174
MEM OPEN 004 = 01912241558
MEM OPEN 005 = 07771234567
MEM OPEN 006 = 01912241559
MEM OPEN 007 = 07897123456
VIDEX 4G
Remember to include “ and , where appropriate. In the example above if locations 001 and 002 already had numbers programmed
then the dial to open numbers (DTO) n1, n2, n3, n4 and n5 would be stored in the GSM starting from location 003 up to 007.
IMPORTANT NOTE: It should be noted that when programming multiple dial to open numbers (DTO) using this command the
GSM starts checking for free memory locations from 001 to see if there is enough available space to store them. So if the number
of DTO numbers being programmed is greater than the number of available locations the GSM will skip to nd the next available
location that has enough space to store the numbers.
For example: the DTO locations from 001 to 003 and locations
from 006 to 008 may be occupied with DTO numbers, location
004, location 005 are available and locations from 009 onwards
are available (refer to table on the right). If the intention is to
store three DTO numbers: 01912243174 (n1), 01912241558
(n2), 07771234567 (n3). The following text message would be
sent to the GSM:
1111STR” 01912243174”,” 01912241558”,” 07771234567”?
The GSM will reply with the following text:
MEM OPEN 009 = 01912243174
MEM OPEN 010 = 01912241558
MEM OPEN 011 = 07771234567
VIDEX 4G
DTO location Location status (free/occupied)
001 occupied location
002 occupied location
003 occupied location
004 free location
005 free location
006 occupied location
007 occupied location
008 occupied location
009 free location
010 free location
011 free location
In the example above although the DTO locations 004 and 005 are available the programming command sent to the GSM is to store
three DTO numbers. As the quantity of DTO numbers to be stored is greater than the number of memory locations available from
location 004 the GSM will look for the next set of free locations that is able to accommodate the three DTO numbers. So in this case
the GSM will bypass locations 004 and 005 as there isn’t sucient space to store the three DTO numbers, it will also bypass locations
006, 007 and 008 as these locations are already occupied. However the locations from 009 onwards are free to use so the GSM will
store the rst DTO number (n1) in location 009 and then the next DTO number (n2) in location 010 and so on.
IMPORTANT NOTE: It is also possible that when storing multiple DTO numbers using the STR code a start location, nnn, can be
included in the programming command i.e. 1111STRnnn”n1”,”n2”,”n3”,”n4”,”n5”. However when a start location is included, while
the GSM will store the DTO numbers from this location, any memory location after it that already has a DTO number stored will
be overwritten with the new DTO number.
Using the same details from the previous example: The DTO locations from 001 to 003 and 006 to 008 are already occupied with DTO
numbers, location 004 and 005 are available. Locations from 009 onwards are also available (refer to previous table). If the intention
is to store the following three DTO numbers: 01912243174 (n1), 01912241558 (n2), 07771234567 (n3) starting from location 004. The
following text message would be sent to the GSM:
1111STR004”01912243174”,”01912241558”,”07771234567”?
The GSM will reply with the following text:
MEM OPEN 004 = 01912243174
MEM OPEN 005 = 01912241558
MEM OPEN 006 = 07771234567
VIDEX 4G
In this example the 1st and 2nd DTO numbers 01912243174 (n1) and 01912241558 (n2) would be stored in the available locations
004 and 005 as expected, however the 3rd DTO number 07771234567 (n3) would overwrite the number that was already stored in
location 006.
DELETE A DIAL TO OPEN NUMBER WITHOUT KNOWING IT’S LOCATION DET
Although it is possible to delete a DTO number from the GSM using the command 1111STRnnn””? , it is also possible to delete a
DTO if the location is unknown. The following texts can be used to delete and conrm deletion of a DTO number from the GSM.
