Downloading Software
The access unit is capable of accepting a software download from a PC through
its COM port to support a file transfer or software upgrade. The Download feature
is used only by your service representative to update your access unit.
File Transfer
The T1 access unit supports a standard File Transfer Protocol (FTP) server over
Transmission Control Protocol (TCP) to allow you to transfer configuration and
program files to/from a T1 access unit node. A complete binary image of the
configuration can be copied to a host to provide a backup. The T1 access unit
must be configured to support FTP sessions.
Initiate an FTP session to a T1 access unit node in the same way as you would
initiate an FTP to any other IP-addressable device.
Be aware of the following rules when doing a file transfer:
You must have Access Level 1 permission to use the put command.
You cannot put a file to the factory.cfg file under the system directory.
You can only put a NAM program file (nam1_ctl.ocd, nam2_low.ocd, or
nam3_hi.ocd) to a T1 access unit. It cannot be uploaded from a node to a
host.
You must change to the /system directory.
Before putting a download file, you must use the “bin” binary command to
place the data connection in Binary mode.
