public class TmSleLink
extends AbstractTmSleLink

Receives TM frames via SLE. The Virtual Channel configuration is identical with the configuration of UdpTmFrameLink.

The SLE specific settings are loaded from sle.yaml based on the sleProvider key specified in the link configuration. The description of the sle.yaml configuration parameters are as follows:

initiatorId	identifier of the local application
responderPortId	Responder Port Identifier
versionNumber	the version number is sent in the bind invocation. We only support the version of the SLE valid in April-2019; however this field is not checked.
myUsername	username that is passed in outgoing SLE messages. A corresponding password has to be specified (in hexadecimal) in the security.yaml file.
peerUsername	username that is used to verify the incoming SLE messages. A corresponding password has to be specified (in hexadecimal) in the security.yaml file.
authLevel	one of NONE, BIND or ALL - it configures which incoming and outgoing PDUs contain authentication information.
service	One of RAF (return all frames) or RCF (return channel frames).
rcfTfVersion	Specifies the requested frame version number (0=TM, 1=AOS, 12=USLP). If this option is not used, the frame version number will be derived from the frameType. If specfied, no validation is performed but sent as configured to the SLE provider.
rcfSpacecraftId	Specifies the number sent as part of the RCF request to the SLE provider. If not specified the spacecraftId will be used.
rcfVcId	Specifies the virtual channel sent as part of the RCF request. If not specified, or if negative, the request will be sent for all VCs
deliveryMode	one of timely, or complete
