This parameter specifies which MTP (Message Transfer Protocol) CDRouter’s USP Controller will use.

Note: CoAP is still supported by CDRouter but the USP conformance tests can no longer be run using this MTP. This MTP was deprecated in USPv1.2 and support for this MTP will eventually be removed from CDRouter.
