Title: Using RFM/5 Commands to Connect Remotely to 3Com ESD Systems
Date: 01/29/90

The RFM/5 (Radio Frequency Modem/5) that attaches to a 3Com
Broadband Controller installed in an IB, CS, or GS/X.25 is
"frequency agile."  This means that the modem may be configured
by software to operate over one of six operating channel pairs.

When configuring the modem, there are several parameters that can
be set, including the transmit channel, the receive channels, the
minimum and maximum transmit levels, etc.  For detailed information
on the available commands and their uses, see the CR/5 and RFM/5
Installation Guide (P/N 3C6309).  (The 3C part number does not
appear in the manual, but each page is marked with the number
09-0090-01, if you need to verify that you have the right manual.)

If the broadband system you are connected to remotely or locally
has older firmware revision levels, it is possible that the RFM/5
configuration commands will not be available.  If this is the case,
you will not be able to issue the missing commands via the user
interface or remote.  Instead, use an RFM/5 terminal adapter
(P/N 3C5905).  The CR/5 and RFM/5 Installation Guide explains how
to use the terminal adapter.

To connect remotely to a CS or other enterprise system device, type
one of these commands, depending on the protocol used:

If using XNS, type

"remote %080002XXXXXX", where XXXXXX are the
         last six digits of the Ethernet address (hexadecimal
 notation) of the device you are remotely connecting to

If using IP, type

"remote XXX.XXX.XXX.XXX", where XXX.XXX.XXX.XXX
         is the IP address (decimal notation) of the device you
 are remotely connecting to

You should then get the remote prompt.  No packets have been
exchanged on the network yet.  The remote prompt indicates only
that all commands will be directed to the device identified by
the address given in your remote initiation command.

When you type a command at the remote prompt, a packet is sent out
over the network to a socket number used by 3Com's network management
protocol.  Because the socket is used, rather than the normal user
interface, only a subset of user interface commands is normally
available.  The command given must be of this subset on the device
remotely connected to; if not, an error message is returned.  Unless
the error message is "unknown errors" or "timed out," the source
is the device which is remotely connected to.
