3.1.2. GSM Gateway Ready Signalling
The GSM Gateway registers the off-hook (current inflow). Immediately and then, if
everything is O.K., starts sending its usual dialling tone . Now the subscriber can
dial the number.
Notes:
•
If GSM gateway needs PIN, special tone is transmitted. See chapter 3.9. Until the
correct PIN is entered, GSM gateway will not allow any outgoing call. Only an
incoming call from PSTN is allowed.
•
In some cases, PBX operates as a repeater. Subscriber will dial whole number, then
PBX repeats it to PSTN line. In this case, subscriber will not hear dialling tone from
GSM gateway.
•
As far as pulse dialling is selected, DTMF dialling can be used to enter programming
mode and program GSM gateway by phone. In case of any other DTMF dialling, GSM
gateway will answer by busy tone.
•
If one network is not accessible, an outgoing call to second one is still possible. User
will hear normal dialling tone, but dialling may cause a busy tone - if inaccessible
network is required. If enabled by par. 5003, the call to inaccessible network can be
rerouted to the second one.
GSM network is not accessible in these instances:
o
GSM module in use (data mode)
o
No SIM
o
GSM network failure, no antenna etc.
PSTN network is not accessible in the case of PSTN line failure - no current.
•
In this moment, GSM gateway also picks up the PSTN line. This help to avoid a
conflict with incoming call from PSTN.
3.1.3. Dialling Receive
The GSM Gateway is ready to receive pulse or tone dialling (according to the set-up). As
soon as the subscriber starts dialling a number, the GSM Gateway mutes the dialling
tone
(as with public telephone exchanges). The user must dial digits in no more
than 6 second intervals; otherwise the number is regarded as complete and sent to the
GSM network (this timeout is programmable).
Notes:
•
If pulse dialling is selected, and the call is routed to PSTN, dialled number is
transformed to DTMF.
•
If pulse dialling is selected, DTMF can be still used for programming.
•
Some PBXs analyse the whole number first and then transmit the dialling into the CO line
(GSM Gateway). Here, the signalling type and the timeout depend on the PBX set-up!
3.1.4. Dialling End Recognition
The GSM Gateway itself can recognize the end of some numbers according to their
length. Moreover, you can set your GSM Gateway in such a way that the GSM Gateway
accepts the ‘*‘ or ‘#‘ (for tone dialling only) symbols as the end of dialling. Otherwise, it
waits 6 seconds after the subscriber stops dialling (the timeout is programmable). Then,
the subscriber can hear a short tone signalling the dialling end.
Note : If the caller goes on dialling, the GSM Gateway will not accept the extra digits!
