3.11 Alternate Terminating Address (ATA) /
Message Forwarding
Message forwarding allows copies of all SC-terminated messages to be sent to an alternate
terminating address (ATA). Any valid e-mail address can be set as the ATA, and any of three
forwarding rules can be applied: carbon copy, conditional, or unconditional. The appropriate
address and rule should be specified when the satellite modem is provisioned.
3.12 Delivery Plan
A delivery plan is the scheme the ORBCOMM gateway uses to attempt delivery of SC-terminated
messages. Delivery plans have four main characteristics:
• Automatic delivery attempts: the number of times, immediately upon receipt and at one-
minute intervals, the ORBCOMM Gateway will attempt to deliver an SC-terminated message
• Time to hold: the maximum time the ORBCOMM Gateway will hold the message before
returning it as undeliverable
• Deletion after final attempt: whether the message should be deleted after the automatic
delivery attempts are exhausted, or held until the time to hold has been reached
• Use of piggybacking: whether a message delivery attempt should be triggered by
successful delivery of another message in either direction
