C-16 INSTALLING INTEL TELEPHONY COMPONENTS

D-Channel Trace utility. Shows you the exact data sent over an ISDN line connecting

TeleVantage and the phone company.

Two B-Channel Transfer test utility. Verifies that you ISDN line has been correctly

configured by the phone company to support Two B-Channel Transfer.

ISDN calls work via the Intel Dialogic Makecall Utility but fail via

TeleVantage

If inbound and outbound ISDN T1/E1 calls work using the Intel Dialogic Makecall Utility

(DMU), but fail when made through TeleVantage, the problem is usually caused by

TeleVantage not correctly detecting that an ISDN protocol has been assigned to the T1/E1 board

on the Interface tab in the Intel Dialogic Configuration Manager (DCM).

1. To diagnose the problem, use Notepad to open the file

TVSTART.TXT, located by

default in

C:\Program Files\TeleVantage Server\Logs). If the Server is indeed not

properly reading the ISDN protocol settings for the board, a line similar to the

following will appear in the log:

[01/25/03 22:16:20.901 - 704 - MainThread ] Device Name : dtiB1, ID :

’0x02’, ISDN Protocol: ’None’, InProtocol: ’’, OutProtocol: ’’, Country:

’US’, Board Name: ’D/240PCI-T1’

In the example above,

ID: ’0x02’

indicates the T1 board with SC-bus ID of 2. You

can determine the SC-bus ID of your T1 board by looking in the DCM or checking the

setting of the rotary switch on top of the T1 board.

2. If a similar entry exists for the malfunctioning T1/E1 board, add the following registry

key values to force the TeleVantage Server open the T1/E1 board in ISDN mode at

startup:

[HKEY_LOCAL_MACHINE\SOFTWARE\Artisoft\TeleVantage\Server\DTIBoardn\

GlobalCall]

“ InProtocol”=“isdn”

“ OutProtocol”=“isdn”

Replace the

DTIBoardn

with the span number, determined by counting the T1/E1

interfaces across all Intel Dialogic boards, beginning with the board with the lowest

SC-bus ID and proceeding through the boards in SC-bus ID-order.

For a board with multiple T1/E1 interfaces, check the Intel Dialogic quick install card

for that board. Quick install cards for most of the Intel Dialogic boards can be found

at the following location:

http://resource.intel.com/telecom/support/Install/Config

To verify that the problem has been resolved:

1. Stop the TeleVantage Server.

2. Stop the Intel Dialogic drivers.
