Note: Cisco 675 has DSL filter built-in for Phone jack. Cisco 678 does not - use an external filter on the Phone port when connecting telephone equipment.

1) With the Cisco Router powered up and plugged into a serial port on the PC, start a HyperTerminal session with these settings:

  Name: Cisco
  Connect using: Com1 or Com2 (Blue cable)
  Bits Per Second: 38400
  Data bits: 8
  Parity: None
  Stop: 1
  Flow Control: None
  Click Ok 

2) Hit <enter>. You should get a response from the router.

3) At the Password prompt: hit <enter>.

4) Go into Enable Mode: 'enable' <enter>

Enter is implied at the end of each line and when a password is requested prior to a password being set.

There are two levels of passwords: Exec and Enable. The Enable mode allows you to change settings.

After the password has been set the password must be entered when requested. Also, after the password has been set, the unit can be configured with a Telnet session.

The default IP address is 10.0.0.1.

  User: enable
  Password: <enable password>

All things in <brackets> must be changed for each different site.

Warning: this device must be disconnected from the phone line before this configuration is installed. Once the final reboot command is given, it may be reconnected.

Erase current configuration and reboot:

cbos# enable
cbos# set nvram erase
cbos# write
cbos# reboot

Configure with static IP address:

cbos# enable
cbos# set ppp wan0-0 login <their-username>
cbos# set ppp wan0-0 pass <their-password>
cbos# set int eth0 address <their-address>
cbos# set int eth0 netmask <their-mask>
cbos# set snmp enabled
cbos# set syslog disabled
cbos# set syslog remote <syslog-server>
cbos# set prompt <customer> (8 char)
cbos# set password exec <customerpassword>
cbos# set password enable <customerpassword>
cbos# set web port 77
cbos# set web disabled
cbos# set tftp disabled
cbos# write
cbos# reboot

For Qwest customers with Cisco 678 routers, there is a choice of CAP or DMT. All customers who connected prior to 1-April-2001 (including simple change of ISP), have to know whether they are CAP or DMT. The 678 can be loaded with either AP or DMT firmware (but you must select one). To find your firmware version, do a “show version” when logged in to the 678.

cbos# set inter wan0-0 close
cbos# set inter wan0-0 vci 1
cbos# set inter wan0-0 vpi 1
cbos# set inter wan0-0 open

cbos# set inter wan0-0 close
cbos# set inter wan0-0 vpi 0
cbos# set inter wan0-0 vci 32
cbos# set inter wan0-0 open

Note: For static routers, DHCP service is generally disabled, although there is no reason why the DSL router cannot be a DHCP server. In the configuration above, DHCP is not turned on, which means that it is off by default.

All things in <brackets> must be changed per installation.

Warning: this device must be disconnected from the phone line before this configuration is installed. Once the final reboot command is given, it may be re-connected to Qwest/US West.
