The Um interface shown in Figure 5-2 is the dedicated wireless traffic channel between the GSP-1620 modem (DCE) and the Gateway Interworking Function (IWF).

Table 5-2 shows the signal lines for each port in Figure 5-2.

The modem signal naming convention assumes that the modem is the DCE and that the user application is the DTE.

Data and Control Port Configurations

For a data application, you can set up the modem to use different configurations of the Data and Control ports:

•Data port only — AT commands can be sent to the modem only when there is no data session active (i.e., no data is coming across the port) or when a data session is active but the Data port is in Online-Command mode.
