7.Enter 1010 using the numeric keypad and press the Enter softkey.

Getting Started

Setting Up a Digital Modulation in the GSM Format

This changes the transmitted data to a ﬁxed 4-bit repeating sequence. The default 4-bit repeating sequence of 0000 is shown in the active entry area of the display.

This changes the pattern from 0000 to 1010. Directly below the visual representation of the timeslot, you should see Data: 1010.

Setting Up Timeslot 7

1.Press Return.

2.Press the Timeslot # softkey. Then enter 7 using the numeric keypad and press the Enter softkey.

3.Press the Timeslot Off On softkey.

4.Press the Timeslot Type softkey.

5.Press the Normal softkey.

6.Press the Conﬁgure Normal softkey.

7.Press the following softkeys:

E > Other Patterns > 4 1’s & 4 0’s.

This moves the softkey menu up one level.

This selects timeslot #7 as the active timeslot. (You can also use the arrow keys to select the timeslots.) The current active timeslot (#7) is displayed in the active entry area.

This toggles the Timeslot Off On softkey from Off to On. Notice that the display now shows that timeslot #7 is turned on.

Another menu of softkeys is displayed.

This changes the timeslot type to a Normal timeslot and automatically returns you to the previous softkey menu. Notice that the Timeslot Type softkey has changed from Custom to Normal. Also notice that the display shows timeslot #7 conﬁgured as a Normal timeslot.

Another menu of softkeys is displayed, allowing you to change the E, S, and TS ﬁelds for the Normal timeslot.

This ﬁlls the E ﬁeld with a repeating sequence of four 1’s followed by four 0’s. Directly below the visual representation of the timeslot, you should see E: P4.
