3.9 Speed Dial
The ORBCOMM gateway maintains a list of up to eight speed dials, or originator/recipient
addresses for each satellite modem. Typically, these speed dials contain the e-mail addresses of
frequent recipients or originators of messages to and from the satellite modem. The use of speed
dials results in a reduced number of bytes in a message. The speed dials can also be used with
message blocking to restrict addresses that can send to the satellite modem and those to which
the satellite modem can send.
NOTE: For the Digi m10 JumpStart Kits, Digi provides automatic e-mail forwarding for
messages with speed-dial destinations. This greatly simplifies your overall evaluation and
development experience by allowing you to define speed dial configurations online at any given
time, without changing the actual satellite service provisioning of your modem. Please refer to the
online help of the Digi Satellite Dashboard application for more information about the speed dial
forwarding. If you have any additional questions, please contact Digi technical support.”
3.10 Message Acknowledgments
Acknowledgments allow a customer to have confidence that SC-originated messages have
reached the Gateway successfully. While ORBCOMM’s implementation of extended SMTP
(ESMTP) allows for delivery notification information for SC-originated messages, the destination
mail server and any mail servers relaying mail along the path to the destination server must also
support the extended version of the protocol. In cases where the customer hosts support ESMTP,
delivery notification is returned to the originating SC in a System Response. In other cases,
results described in a System Response as referring to delivery to the message recipient can be
misleading. An acknowledgment from the ORBCOMM Gateway is implicit in the delivery protocol
for MESSAGES, and is implemented regardless of the specified acknowledgment level. No
acknowledgment by the Gateway is available for Global Grams. For Data Reports, the service
type specified for the message determines the acknowledgment level.
