Modem Data-Only

This type of modem data station includes only DTE and a modem (see
5-2). The modem connects to the control unit through an analog port on a T/R
module. If the modem does not provide dialing capability, a single-line telephone
can be connected to it to provide dial-out capability; however, the data station and
the telephone cannot be used simultaneously.
