Analog Voice and Modem Data	5

This type of modem data station includes an analog multiline telephone, a modem, and a DTE (a data terminal or PC) (see Figure 5–1). The modem connects to the control unit through the T/R interface of a General-Purpose Adapter (GPA). The telephone connects to the system through an analog port on the control unit.

The port configuration requires two adjacent odd/even extension jacks on a 408, 408 GS/LS, or 008 module in the control unit. The even jack is for voice and the odd jack is for data. The bridging adapter joins the odd/even jack pair for connection to the analog multiline telephone. The telephone provides the dialing capability for the data station.
