The serial port on the router uses a universal port, a 60-pin receptacle that supports the
following serial interfaces: EIA/TIA-232, EIA/TIA-449, X.21, V.35, and EIA-530. The
shielded serial transition cable determines the electrical interface type. The router end of all
of the cables is a 60-pin connector.
DTE connectors have a plug connector at the network end. (DCE connectors have a
receptacle at the network end.) However, V.35 is available in DTE mode either a receptacle
or a plug connector at the network end. The serial port operates in DTE and DCE modes.
The tables that follow list the signal pinouts for the DTE mode serial transition cables for
each router interface type.
Figure C-2 shows the EIA/TIA-232 serial cable assembly, and Table C-8 lists the
EIA/TIA-232 cable pinouts.
