There are 3 connectors
that interface between the modem board and the the main board.
|CN5||serial connection to the modem|
|CN7||this connector leads to the 2 telephone jacks|
The hack is basically a ribbon cable that connects between CN5 on the main board of the cable modem
and your external modem.
On one end, we have a 12 pin (or greater) IDC connector, and on the other end, a 9 or 25 pin D-sub.
The internal 14.4Kbps modem is no longer used, and can be either removed, or left inside.
Here are the pinouts for 9 and 25 pin connectors:
|CN5 on the main board||Description||9-pin dsub||25 pin dsub|
cut the end off of a joystick port connector and used the ribbon and 16
pin IDC connector.
There were rows left open at the end, but that was ok. Soldering this to a 9 pin male dsub
is recommended because most of the wires line up and fall right into place.
After you are done,
plug the connector into your external modem, plug your phone lines, network
cable lines into the whole contraption and then power cycle your HYBRID CCM-202. You
should hear it dial in and then you are ready to upload 2-4x faster.
