Setting Up the Cisco 678 Hardware Environment
Configure the Serial Port
For the best access to the CBOS, use your terminal emulation program (such as
HyperTerminal in Windows) to set your COM protocol to the following settings:
• Baud rate: 38400 bps recommended (standard 9600 bps possible)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
Connect All Cables to the Network
The procedure for connecting cables differs depending on whether or not your
telephone equipment is connected to a POTS splitter.
POTS Splitter Configuration
A POTS splitter separates data signals from voice signals on your telephone line.
The POTS splitter works by running a separate data line from the voice line, so
that the ADSL router has a dedicated cable for data transmission. Figure 2-3
shows telephone equipment connected to a POTS splitter. In Figure 2-3 and
Figure 2-4, the PHONE port cannot be used. Figure 2-6 shows how to connect all
cables to the Cisco 678 ADSL router.
