Configuring the Xstream to Make an ISDN Call

1.Plug your ISDN line into the back of the codec and press the "Codec" button below the LCD screen on the Xstream.

2."Transmit" should be highlighted and this lets you select your transmit algorithm of choice. If it is not selected use the arrow buttons on the right-hand side of the LCD screen to navigate to this menu item and press the "SEL" button to the right of the LCD screen to select the menu.

3.Use the arrow buttons to navigate to:

"G.722".

"L2 J-Stereo" (for an MPEG Layer 2 stereo connection), or

"L2 Mono 64" or "L2 Mono 128" (for a mono connection, depending on whether you have one or two B channels available).

4.Press the "SEL" button to store your setting and use the arrow down button to navigate to "Receive".

5.Press the "SEL" button and select the same algorithm that you selected for "Transmit" previously and then press the "SEL" button to store your setting.

Important Note: It you don't select the same algorithm for "Transmit" and "Receive" algorithms then it can take a long time to connect as the algorithms are scanned by the codec, or the wrong algorithm could be selected.

 

6.Use the arrow buttons to navigate to "Bitrate" and check that it displays "64kbps" - this is a per channel rate so both ISDN channels are programmed.

7.Use the arrow buttons to navigate to "Sample" and check that the sample rate is set at "48kHz". Press the "SEL" button and use the arrow buttons to make any adjustments to the current setting.

8.Press the "Tel" button below the codec LCD screen and press it again to display the "SPID" and "DN/MSN" screen. If these numbers need to be entered (check with your Telco), use the arrow buttons to navigate to each SPID and DN/MSN field in turn and when it is highlighted press the "SEL" button and enter the number using the keypad. Press "SEL" again to store each number once it has been entered.

9.Press the "Tel" button if you are not entering these SPID/DN/MSN numbers, or if you have already entered them, and check the local ISDN switch type setting is configured for your region.

10.Press the "SEL" button and use the arrow buttons to adjust the setting.

Select "ETS300" if you are connecting to a Euro ISDN service.

"Natl.I-1" is the most common in the US but check with your Telco.

11.Press the "SEL" button to store the ISDN switch type setting that you have selected.

 

Your codec should now be configured. Press the "Tel" button on the front panel until it displays the "ISDN Status" screen. "Ready" should be displayed next to any active lines. If this is not displayed, check your connections and settings to make sure they are correct.
