SBX IP 320 Features & Operation Guide
To send an SMS message from an SMS SLT:
1.
User composes an SMS message from SMS SLT.
2.
User initiates the transmission of the message.
Actually, the procedure is the same even if the SMS SLT is connected to the SBX IP 320 system.
That is, the user edits an SMS message from the SMS SLT and initiates the transmission.
(This is the end of operation from the user side)
Then, the SLT sends the SMS message to the SMS service center.
At the beginning stage of sending the SMS message, the SBX IP 320 system routes the call from
the SMS SLT to the SMS service center so that the message can be sent to the destination
properly.
To receive an SMS:
1.
When an incoming call comes in with the same Caller ID in "SMS Service Center CLI",
then the system connects the CO with the SMS channel to receive the SMS from the
PSTN.
2.
The SMS message delivery is completed and the SMS message is saved in the memory of
the SBX IP 320 system.
3.
If the assigned station of application is a DKTU, the SMS message is sent to the
application. And the system deletes the SMS message from the memory of the SBX IP
320 system.
4.
If the assigned station is a DKTU without ez-Phone, the LCD display of the DKTU
indicates the SMS arrival.
5.
If the assigned station is an SMS SLT, the system regenerates the SMS message to the
SLT phone. When the SMS SLT receives a SMS message correctly, the system deletes
the SMS message from the memory of the SBX IP 320 system.
