Connecting Interface Cables
Figure 3-17 Serial Port Adapter Cable Connections
Note The serial port adapter cable determines the electrical interface type and mode of the FSIP
port. When connecting a remote DTE device (which means that the FSIP port is a DCE interface),
you must set the clockrate with the clockrate command. For an example configuration using this
command, refer to “Configuring Timing (Clock) Signals” in the chapter “Maintenance.” For
complete command descriptions and instructions, refer to the related software documentation.
Caution The SIP and FSIP each use unique interface cables that are not interchangeable.
Attempting to force a SIP cable (which uses DB-15 or DB-25 plugs) into the FSIP universal, 60-pin
receptacle can damage the FSIP. (See Figure 3-18.)
