A stand-alone modem includes a power transformer. The unit conditions
the power supply.

The off-line configuration (OLC) button is on the back panel of some
stand-alone modems.

Pressing the button makes the modem enter command mode, in which
the user in synchronous or leased-line environments can change
configuration options.

Cards and stand-alone modems have the following front panel
interfaces (Figure D-3, Figure D-3, and Figure D-4).
