APPENDIX B
CONFIGURING INTEL DIALOGIC
B
OARD ISDN PARAMETERS
Some sites may need to modify the ISDN parameters used for outgoing calls so that their ISDN
trunks will work with TeleVantage.
To determine if you have a problem, do the following:
Install Intel Dialogic hardware and software according to the instructions in this manual.
See Configuring ISDN PRI T1 or ISDN PRI E1 trunk boards on page 7-22 and
Configuring ISDN BRI trunk boards on page 7-25. Also, see Administering
TeleVa ntage for information on adding an ISDN span using the TeleVantage
Administrator.
Try placing calls on the ISDN line using TeleVantage. If calls from TeleVantage work,
there is no need to troubleshoot your line or modify any ISDN parameters.
If you cannot place calls successfully, follow the instructions in this Appendix to use the
following troubleshooting utilities to place calls and diagnose problems on your ISDN line:
Intel Dialogic Makecall Utility (DMU). See page B-2.
Intel Dialogic ISDIAG utility. See page B-2.
TeleVantage D-Channel ISDN trace utility. See page B-5.
TeleVantage Two B-Channel Transfer test utility. See page B-9.
To troubleshoot problems on your ISDN line
1. Ask your ISDN carrier for the optimal protocol values for your line. Enter them into
the Windows registry as described in Changing TeleVantage ISDN protocol
parameters on page B-4.
2. If calls from TeleVantage still fail, use the DMU to determine the protocol values for
your line. See the next section, Using the Intel Dialogic Makecall Utility on
page B-2.
3. If calls from the DMU fail, use ISDIAG to determine why the Intel Dialogic board
cannot communicate with your ISDN line. See Using ISDIAG on page B-2.
4. If you are having difficulty configuring outbound Caller ID or need to see the exact
data that is being sent between the phone company and TeleVantage, see Using the
TeleVantage D-Channel ISDN trace utility on page B-5.
5. If you are using the NI2 protocol with ISDN PRI T1 lines and the Two B-Channel
Transfer feature, and the Two B-Channel Transfer feature is not working, see Using
the ISDN Two B-Channel Transfer test utility on page B-9.
