Testing ISDN Connections
To test your ISDN line is working you can dial a standard phone line or your cell-phone number. If
the call is successful this verifies the line is active. To verify ISDN data is being sent you can:
·
Dial a codec you know is connected to an active ISDN line, e.g. another codec in your
network or a Tieline test codec.
·
Dial the test ISDN data number provided by your Telco (when available).
·
Create a program and perform a loopback test by dialing out on the main ISDN number and
receive the call on the auxiliary ISDN number. (
Note:
To create a loopback program create a
2 x Mono or Stereo Peer-to-Peer program and configure a dial only audio stream using your
main ISDN number. For the second audio stream create an answer only audio stream
connection configured for ISDN. If you dial the connection and can hear the audio you are
sending on the return B channel, you have confirmed ISDN data is being sent successfully.
If you dial using a loopback program and a "disconnect" error message similar to the following
image appears, you may have the incorrect
Line Type
configured.
Change the
Line Type
setting and this should hopefully resolve the issue.
On-Demand ISDN Services
If
Sync
appears for approximately 60 seconds when you connect an ISDN line to the codec and
then disappears, or if
Sync
does not appear and you know you are connected to an active ISDN
interface, then the line may have ‘On-demand’ enabled by your Telco. To test this you can dial a
codec on an ISDN line known to be operational. Dial over ISDN and if
Sync
appears after connecting
it indicates the service has now been activated. Disconnect and then dial again. If this dial is
successful ‘On Demand’ is enabled. We recommend you contact your network service provider and
get them to disable ‘On Demand’ to circumvent any possible connection issues.
27.7
Connecting Tieline ISDN to other Codecs
To dial from a Tieline codec to a non-Tieline codec it is necessary to disable ‘Session Data’ and
use an algorithm like G.722 or MPEG Layer 2 for compatibility. The same settings must be
configured at both ends for:
·
Mono or stereo
·
Encoding (Algorithm)
·
Sample Rate
·
Other relevant settings on the non-Tieline codecFollowing are configuration instructions for
dialing to several non-Tieline codec brands over ISDN.

Connecting to APT Wordcast Equinox ISDN
Configuring the WorldCast Equinox to Make an ISDN Call

2. Press the "Menu" button on the codec to access the codec menus.
3. Press the "Menu" button to select the "USER" menu.
