Preparing Network Connections

Universal Serial Cables

The universal FSIP ports for all interface types are 60-pin, D-shell receptacles. Each port requires a
serial port adapter cable to connect to the external network or connection device.
On data communications ports, the universal port adapter cable determines the electrical interface
type and mode of the port. All universal cables use a 60-pin D-shell plug at the router (FSIP) end.
The network end of each cable provides the standard connector used with each respective interface
type. (See Figure 2-30.) Cables for all data communications interfaces except EIA-530 are available
in DTE mode with a plug at the network end, or in DCE mode with a receptacle at the network end.
The mode, DCE or DTE, is labeled on the connectors at both ends of the cables.

Metric (M3) thumbscrews are included with each port adapter cable to allow connection to devices
that use metric hardware. Following are the available interface cable options for the mode and
