Carrier level templates are most often used to apply specific settings or formatting requirements to your method of delivery and most of the variables you'll apply will be in the Settings section. For more information, please review the Template Components section of the documentation. Applying a custom template to a carrier tells PageGate to format messages delivered via this carrier in a certain way. Most carriers do not require a custom template but there may be things you want to customize about the look, output or specific format of your messages.
All delivery protocols have specific variables that can be used in the Settings section of a corresponding carrier template. These variables can be broken down in to a few categories: Protocol Delivery and Content Modification
Protocol Delivery
These parameters modify the behavior of a protocol and specify certain declarations that must be made during the protocol negotiation sequence.
