SMS-initiated PPP
In environments where Local Managers contact the Control Center as needed via wireless modem, contact can be initiated from the Control Center by sending an SMS message instructing a Local Manager to phone home in order to connect to the network out-of-band.
Requirements for using this capability are:
- The Local Manager uses a wireless modem (GPRS/CDMA/Iridium/Inmarsat) modem that supports SMS commands.
- The Local Manager has been configured with a phone number and SMS domain name that the Control Center can use to construct a valid SMS email address. These are locally configured with the config answer command.
- An SMS modem monitor with automation (i.e., a rule/ruleset) has been configured for the modem to monitor for SMS messages. The included smsPppOn rule can be used in conjunction with this monitor.
To initiate contact:
- Select the Local Manager from the Inventory and expand the page to show the Local Manager detail.
- Click Schedule Task and from the list of tasks that may be scheduled, select SMS Message and click Next.
- The SMS Message - Parameters page opens. Click Next and the ppp on command is sent immediately by SMS message. It may take a few minutes before the Local Manager receives the SMS message and activates PPP to phone home.
