Telos ZephyrExpress user manual Call yourself testing your unit and the line, Configure the Codec

h Turn the knob to select the switch type for this line, and tap to confirm.

HOT TIP!

The currently-selected switch type will have brackets around it (like [PTP]). If the current switch is correct for your line, select a different type and tap the knob to confirm. Then wait a few seconds, and select the proper one and confirm.

This will force ZephyrExpress to resynchronize to the line using your circuit numbers.

Hold the edit knob in toward the panel for about five seconds. This will take you back up through the menu system, back to the Status screen. Then release the knob.

In a few seconds, you should see the word Ready in each of the boxes on the bottom of the screen.

∙If you don’t see Ready twice on the Status screen, go back and check to make sure you’ve entered all the numbers and the switch type correctly.

∙If that doesn’t work, turn to the Troubleshooting section of this manual.

Call yourself (testing your unit and the line)

Before you call our test lines, make sure ZephyrExpress is working properly with the phone system. The easiest way to do this is to place a call on one of your ISDN lines, through the telco’s central office, and back to yourself!

Verify that the word Ready appears twice on ZephyrExpress’ screen. If it doesn’t, go back through the previous few pages to configure the system for your ISDN line.

Configure the Codec

Check the Status screen. If it shows Transmit L3-DUALand Receive L3-STEREOlike the picture below, you can skip the configuration steps and go to Place the Call on page 1-9.

If the Transmit or Receive modes are different from the picture above, follow the following steps:
