The NTP timeout is decremented and, on expiry, a NTP frame is generated. This contains the Network Time as perceived by the system, together with an estimate of the transmission delay imposed by this system. Hytec Electronics Ltd - Page 103... -
Page 104: A3.3.3 Received Ethernet Frame
A received ERP response frame is noted in the relevant entry in the LLC3 Control Table. If there is a User Command active, it is completed to the User with an error status and no other Commands are acted upon until the ERP active frame is received. Hytec Electronics Ltd– Page 104... - Page 105 ECC. An immediate response from an ECC returns user data, while a deferred response acknowledges receipt of the user data. The returning user data is encoded in an LLC3 command at some later time. Hytec Electronics Ltd - Page 105...
