Control Port Operation HDSL4 for General Distribution Installation and Maintenance Practice52 61223HDSL4L2-5CDownload HTUC via TFTPThe Download H4TUC via TFTP screen (Figure 49) is utilized to perform a TFTP file transferfrom a remotely located computer/server to the H4TU-C. During TFTP transfers, the SCUcontinues to act as an intermediary to receive the file data from the remote computer and thensend it to the H4TU-C unit. Before initiating a TFTP transfer from the menu screen, first enterthe TFTP remote filename that is listed on H4TU-C TFTP menu (option 1). The IP address ofthe remotely located computer must also be set from the network management menu on theSCU.In addition, the Ethernet interface of the SCU must also be provisioned properly for TFTPtransfers. The Ethernet interface settings allow the SCU to communicate properly over theEthernet network in which it is installed. If settings are improperly entered, neither Telnetsessions nor remote TFTP file transfers will be available.Refer to the appropriate SCU Installation and Maintenance Practice for details on Ethernetsettings.Once the H4TU-C and SCU have been provisioned properly for the TFTP file transfer, selectoption 2 from the H4TU-C TFTP file transfer menu screen to initiate the TFTP file transfer fromthe remotely located computer to the H4TU-C. TFTP file transfers are typically faster than Y-Modem transfers. Once the SCU receives the file from the remote computer, the file is sentfrom the SCU to the H4TU-C to be downloaded (typically less than 2 minutes).TFTP transfers can also be initiated remotely using SNMP - totally eliminating the need tophysically be at the Total Access 3000 shelf to update the H4TU-C.Figure 49.
