OK fist we are going to start with PPP.
Note that any users on a DSL line using PPPoE would not be able to use PPP will get on that later...

Here is an example configuration for a Cisco 678 DMT.

First we are going to logging in to the command console here are the steps...

1* Connect the cable to the back of the router in the MGNT port and then to the back of your computer to COM 1.

2* Open Hyper Terminal and create a new connection, set it as follows, 1: Name the connection Cisco, 2: Ignore the first three fields and in the third "Connect using" set it to COM1. Click ok.

3* Set Bits per second to 38400, Data Bits 8, parity none, Stop Bits 1, Flow control None. click ok.
Then your Hyper Terminal Session screen will pop up. Hit Enter.

5* User Access Verification
Password: Is the next thing that appears. If this is a new router hit enter. Otherwise enter the password and hit enter.

6* cbos> appears. Type enable and hit enter.

7* enter the exec password then enter or hit enter if a new router.

8* cbos# appears. You are now in "Enable" mode and can setup your DSL router!

Here is a list of commands that will get up up and running if your ISP set you up with a dynamic IP address.

set nvram erase
write
reboot
Get back into the "enable" mode as you did above.
set password enable ~Make up a password~
set password exec ~Make up a password~ I use the same password I did above, easier to remember
set ppp restart enabled
set ppp wan0-0 ipcp 0.0.0.0
set ppp wan0-0 dns 0.0.0.0
set ppp wan0-0 login ( Supplied by your ISP )
set ppp wan0-0 password ( Supplied by your ISP )
set nat enable
set nat timeout udp 3600 ( for online gaming )
set nat timeout icmp 3600 ( for online gaming )
set dhcp server enable
set int wan0-0 disable
write
set int wan0-0 vpi 0 ( Supplied by your ISP )
set int wan0-0 vci 35 ( Supplied by your ISP )
set int wan0-0 enable
set ppp wan0-0 subnet 0.0.0.0
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

You are finished! Close Hyper Terminal and you should be able to connect to the Internet!

Note:
On CBOS 2.4.6 and up you do not have to set the web disable because these burnability is address...
But for double security you can still disable it ;)
Also the VPI/VCI vary upon ISP so you might want to call your ISP and ask them what is there VPI/VCI. The one I posted above is for SBC.

Now here are the steps for PPP if you have a Cisco 678 CAP.

1* Connect the cable to the back of the router in the MGNT port and then to the back of your computer to COM 1.

2* Open Hyper Terminal and create a new connection, set it as follows, 1: Name the connection Cisco, 2: Ignore the first three fields and in the third "Connect using" set it to COM1. Click ok.

3* Set Bits per second to 38400, Data Bits 8, parity none, Stop Bits 1, Flow control None. click ok.
Then your Hyper Terminal Session screen will pop up. Hit Enter.

5* User Access Verification
Password: Is the next thing that appears. If this is a new router hit enter. Otherwise enter the password and hit enter.

6* cbos> appears. Type enable and hit enter.

7* enter the exec password then enter or hit enter if a new router.

8* cbos# appears. You are now in "Enable" mode and can setup your DSL router!

set nvram erase
write
reboot
Get back into the "enable" mode as you did above.
set password enable ~Make up a password~
set password exec ~Make up a password~ I use the same password I did above, easier to remember
set ppp restart enabled
set ppp wan0-0 ipcp 0.0.0.0
set ppp wan0-0 dns 0.0.0.0
set ppp wan0-0 login ( Supplied by your ISP )
set ppp wan0-0 password ( Supplied by your ISP )
set nat enable
set nat timeout udp 3600 ( for online gaming )
set nat timeout icmp 3600 ( for online gaming )
set dhcp server enable
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

You are finished! Close Hyper Terminal and you should be able to connect to the Internet

And you are done :)

Now to bridge mode :)
To any DSL ISP that uses PPPoE these is the only option you only have to use with these modem because the Cisco 678 does not uses PPPoE for authentication.
So you will need a router or a Hardware Firewall to handle the PPPoE for you.

1* Connect the cable to the back of the router in the MGNT port and then to the back of your computer to COM 1.

2* Open Hyper Terminal and create a new connection, set it as follows, 1: Name the connection Cisco, 2: Ignore the first three fields and in the third "Connect using" set it to COM1. Click ok.

3* Set Bits per second to 38400, Data Bits 8, parity none, Stop Bits 1, Flow control None. click ok.
Then your Hyper Terminal Session screen will pop up. Hit Enter.

5* User Access Verification
Password: Is the next thing that appears. If this is a new router hit enter. Otherwise enter the password and hit enter.

6* cbos> appears. Type enable and hit enter.

7* enter the exec password then enter or hit enter if a new router.

8* cbos# appears. You are now in "Enable" mode and can setup your DSL router!

set nvram erase
write
reboot
Get back into the "enable" mode as you did above.
set password enable ~Make up a password~
set password exec ~Make up a password~ I use the same password I did above, easier to remember.
set bridging rfc1483 enable
write
reboot
enable
set client dhcp enable or (disable if your going to do dhcp from firewall)
write
set int wan0-0 disable
write
set int wan0-0 vpi 0 ( Supplied by your ISP )
set int wan0-0 vci 35 ( Supplied by your ISP )
set int wan0-0 enable
set web disable ( Code Red Virus Deterrent!)
set web port 8081 ( Code Red Virus Deterrent!)
set web remote 255.255.255.255 ( Code Red Virus Deterrent!)
write
reboot

You are finished! Close Hyper Terminal and you should be able to connect to the Internet

These will get you going in no time :)

Good Luck.
