Gateway configuration for SMS messages to a GSM modem
REF 542plus can be either configured to function as a gateway for SMS
messages to the GSM modem, or as a normal SMS message source.
As the gateway function is configured, REF 542plus will receive all SMS
messages from the Ethernet network and forward them to the GSM modem
for transmitting into the GSM network. REF 542plus is forwarding all the
SMS messages that are sending to this (Gateway) IP address. Also, the SMS
messages generated by the gateway itself are sent to the GSM for
transmitting.
As the SMS message source is configured, REF 542plus will send its SMS
message to the Gateway IP address. The gateway is then forwarding this
message to the GSM modem.
