Data Stations
Figure 6-1 shows the equipment configuration for an analog voice and modem
data station.

GPA Settings

The switch on the back of the General Purpose Adapter (GPA) used in Step 4,
provides two settings, Automatic and Basic (Join is not used).
Use the Basic setting to originate:
Modem calls
Telephone calls while using the modem
When the GPA is connected to an analog multiline telephone and configured
using the Automatic setting, you can:
Answer calls (if this is the case, an Auto Answer All button must be
programmed so that calls can be answered automatically).
Make and receive calls on the telephone while using the modem. The
speakerphone must not be used.

Setting Up

To set up an analog voice and modem data station, follow the steps below:
If using an external modem, use an EIA-232-D cable to connect the

SERIAL port on the data terminal to the modem. If using an internal
modem, it should already be connected to the correct serial port.
If the data terminal has both COM1 and COM2 ports, make sure you use
the one designated for data transmission. See the customer's system
manager if you are not sure.
