4.2 Cisco·Cisco 678 - Does it work with the current Qwest DSL offerings?
·Where can I get the latest DMT firmware for my Cisco 678?
·Cisco 67x - How to Build Management Cable
·What is an example configuration for my 800 series router?
| | | The answer depends on the service:
The 678 will work with all of their regular ADSL offerings (the 7Mbps/1.0Mb and slower services).
However since the 678 does not support ADSL2+ it will not work with the more recent (and rarer) 12Mbps and 20Mbps Qwest offerings.
Regardless of what some Qwest representatives may say, the modem WILL work (with the 7Mbps and lower offerings). Any confusion about this is likely due to the fact that the 678 is no-longer sold or officially supported by Qwest.
A note regarding PPPoE and PPPoA and the Cisco 678 modem:
Qwest has switched to using PPPoE in many areas, and the 678 does not internally support PPPoE authentication. If you live in one of the areas where PPPoE is the only authentication available and you want to use the 678, you will need to put the modem into bridged mode and use a device (PC or router for example) to do the PPPoE authentication.

»www.qwest.com/dsl/customerservic···dmt.html
This will get you to CBOS v2.4.6.

»www.cisco.com/en/US/tech/tk175/t···33.shtml
An alternative is to use a straight RJ-45 CAT5 cable, and purchase an RJ-45 to DB-9 Female adapter (example: »www.sealevel.com/product_detail.···_Adapter) and wire up the pins you need. The Cisco 67x only uses three wires for communication, depending on the colored wires inside the adapter:
Flat Standard: YELLOW->2, GREEN->3, RED->5
568B Standard: GREEN->2, WHITE/BLUE->3, BLUE->5
Cut or individually tape up the unused wires in the RJ-45 to DB-9 adapter so they don't touch or short out. Plug the adapter into a serial port on your computer, and the RJ-45 cable between the adapter and the management port of your 67x.
The Cisco 67x DSL router uses a different management cable than the Console cable used on other Cisco products (2500, etc.), so if you find one for sale or on an auction, be sure it is specifically for the Cisco 67x.
