WARNING:
■ Before plugging or unplugging the interface cable connected to the SIC-1SAE
card, power off the router. Online insertion or removal tends to damage the
port and even the device.
■ Before connecting the SIC-1SAE card to a remote device, identify the type of
the device, such as its synchronous/asynchronous mode and DTE/DCE mode,
and the signaling criterion, baud rate and time clock required by the access
device.
