CHANGING A CISCO 675 and 678 into PPP MODE

    Note: The Cisco 675 is referred to, but the Cisco 678
          should require identical configuration.

To change a Cisco 675 into PPP mode, connect up the management
cable from the Cisco 675 to the computer.  The management cable
is probably gray or blue, it has one side that looks like a
network cable (like a fat phone line), that plugs into the MGMT
port on the back of the Cisco 675, and the other side that is a
9 pin serial port, that plugs into the computer.

Once the cable is connected up, start up Hyper-terminal, usually
in the Start menu, in Programs -> Accessories -> Communications
-> Hyper-terminal.  This will open up the Hyper-terminal window.
Double click on "Hypertrm.exe" or just "Hypertrm" to start the
Hyper-terminal program.

When Hyper-terminal starts, it will ask for the name of the
connection, call it Cisco675 and click "OK".  The next window
should have a section "Connect using", choose Direct to Com1
(or Com2, if the cable is plugged into Com2 on the PC.  You may
have to try both Com1 and Com2 if you are not sure which you
plugged the cable into).

Now the Port settings window will come up.  Adjust it so it
looks like the following:

Bits per second:	9600    (for Cisco 675)
Bits per second:	38400   (for Cisco 678)
Data bits:		8
Parity:			None
Stop bits:		1
Flow control:		None

You should now be connected to the Cisco 675 management (MGMT)
port.  Press ENTER a few times and you should see a Password:
or "cbos>" prompt.  If you don't, try unplugging the Cisco 675
for 10 seconds and plugging it back in.  Then press ENTER a
few times again.  If you still don't see a Password: prompt or
a "cbos>" prompt, the wrong Com port may have been selected.
In that case, go into the File menu in Hyper-terminal and choose
Properties.  Change the "Connect using" box to the other Com
port.  If you are using "Direct to Com1" now, change it to
"Direct to Com2", or vice versa.

Now press ENTER a few times, if you still don't see a
"Password:" prompt, power off the Cisco 675 for 10 seconds,
then plug it back in.  You should now get a "Password:" or
"cbos>" prompt.

Once you are at the Password: prompt, enter your Cisco 675
password, or if you don't have one, press ENTER.  That should
get you to a "cbos>" prompt.  Now type in "enable" and press
ENTER.  It will now ask for a password again.  Enter your
Cisco 675 enable password, or press ENTER if you don't have
one.  You should now be at a "cbos#" prompt.

At the "cbos#" prompt, type in the following, pressing the
ENTER key after each line:

	set nvram erase
	write
	reboot

After the Cisco 675 reboots, you'll should back at the main
password prompt again.  Press ENTER a few times again if you
don't see the "Password:" prompt.  Again, enter your Cisco 675
password, of if you don't have one, press ENTER.  That should
get you to a "cbos>" prompt.  Once again, type in "enable" and
press ENTER.  It will now ask for a password again.  Enter your
Cisco 675 enable password, or press ENTER if you don't have
one.  You should now be back at a "cbos#" prompt.

At the "cbos#" prompt, type in the following, pressing the
ENTER key after each line:

	set ppp wan0-0 ipcp 0.0.0.0
	set ppp wan0-0 dns 0.0.0.0
	set ppp wan0-0 login ppp
	set ppp wan0-0 password ppp
	set nat enable
	set dhcp server enable
	set password exec SECRET-PASSWORD
		NOTE - VERY IMPORTANT
			Write down the SECRET-PASSWORD you
			use there is no way to recover it.
	write
	reboot

That should do it, your Cisco 675 should now be in PPP
mode.  It should be up and running.  If you have a
Cisco 678, there are a few more commands to type in:

If you have a Cisco 678, there
are a few more commands to type in:

        show int wan0-0
        set int wan0-0 disable
        write
        set int wan0-0 vpi 0            (CAP use: vpi 1)*
        set int wan0-0 vci 32           (CAP use: vci 1)*
        set int wan0-0 ena
        write
        reboot

*CAP is the older format for Qwest DSL, the new format is DMT.
 Most DSL lines are DMT.  If your DSL was installed before
 2002, please call Zipcon at 206-524-0612 and we'll find out
 if your DSL line is CAP or DMT.

That completes the configuration for the Cisco 678.

When you exit Hyper-terminal, if you get a "You are currently
connected.  Are you sure you want to disconnect now", choose
Yes.  It may then ask "Do you want to save session Cisco675",
choose Yes.  Now the next time you want to connect into the
Cisco 675, just double click on the Cisco675 icon.


Please let me know if you have questions or problems.  Thanks, Dan
