i would like to ask what is the AT command sequence for the fax handshake (if there is any…)…
anyway, i would like to describe below my set-up and procedures that i have done, and in hopefully you would be able to point me to some directions to move into…
Setup:
Equip 1: Mobile Station (PC and Fastrack Supreme - Using mobile SIM with Data call support)
Equip 2: Landline Station (PC and Conexant Modem - Using a PSTN FAX number)
Procedure 1:
From Equip 1 PC Hyperterminal, dial Equip 2 number “atd07xxxxxxx” .
At Equip 2 PC Hyperterminal, “Ring” displays
From Equip 2 PC Hyperterminal, type “ata” to to answer the call.
“fax handshake” occurs, (i can hear the sound/noise when the modem tries to connect to each other)
Equip 1 and Equip 2 are connected, so you can type characters from Equip 1 PC Hyperterminal and it is displayed in Equip 2 PC hyperterminal.
–> Setup and Procedure 1 = OK.
Procedure 2:
From Equip 2 PC Hyperterminal, dial Equip 1 number “atd021xxxxxxx” .
At Equip 1 PC Hyperterminal, “Ring” displays
From Equip 1 PC Hyperterminal, type “ata” to to answer the call.
–> at this point i do not know what to do for the “fax handshake” to occur or for the modem to connect to each other…
–> from Equip 2, i could still hear a tone beeping, i would guess that the Equip 2 is waiting for some command or identification from Equip 1…
i hope i explained my problem clearly…if you need more information, i would be happy to comply…thank you very much…
can you please tell me how would i be able to establish a data call from my PSTN line (Equip 2-from the above) to my Mobile Station (Equip 1)…thank you very much…
i gave my GSM service provider a ring, and i was told that i would have the same “data number” for the incoming data call, and that the number that i am currently using would be able to handle both voice and data call.
i have mentioned in my earlier post, that i could hear a tone beeping from my equip 2 (Landline Station -PC and Conexant Modem - Using a PSTN FAX number-). anyway, i tried calling my mobile and my colleagues mobile using equip 2, and i was able to hear the same tone from my mobile. i reckon, it would be the data (fax) number waiting for an identification or some confirmation from the receiving number…
do you have any thoughts that i could try to work on… i have been searchin this forum and the web for some and i was not successful so far…i also have read and re-read the documents that i have downloaded from the wavecom website but still i came up short…i would appreciate much if you could give me headstart…thanks…
below is a step by step process of what i am trying to do.
From the PSTN Modem dial the Fastrack Modem number.
In the Fastrack Modem a “RING” is displayed
In the Fastrack Modem answer the call “ATA”
–> at this point, no data connection is established.
–>i can still here the tone beeping sound from the PSTN Modem.
i have also tried all the bearer type selection values, i.e. at+cbst= 1,0,1; at+cbst=7,0,1, etc… but still i cannot establish a data call connection.
i am from New Zealand, the PSTN operator is Vodafone, and i am also using Vodafone pre-pay SIM.
I don’t know how your networks work down there, but up here they (including Vodafone) assign separate numbers for voice and data.
I think you really need to find a local Wavecom distributor to advise you on this - if your networks are anything like ours, you stand no chance of getting anything useful out of their customer helplines.
See: viewtopic.php?f=34&t=1106
Or perhaps you could find a specialist M2M service provider…?
thanks for your reply mate…i gave Vodafone customer helpline another ring to ask why is it that i cannot accept data call from my pre-pay SIM card considering that i was told that i should be able to do so…anyway, lo and behold, i was told that for the pre-pay SIM card, data call is not available, and that they do not provide data numbers for pre-pay SIM card…what a waste of time trying to figure out what was wrong in what i have been trying to do…
anyway, i am now trying to find an economical way of acquiring a SIM card with data call (i.e. with separate data number)…i will keep you posted for any development…
