J-20 INSTALLING TELEVANTAGE
Disabling Dialogic devices _________________________________
By default, TeleVantage allocates and opens all Dialogic devices that are present on the Server
for itself. If you do not want TeleVantage to allocate all of the available devices, use the
procedure described later in this section to disable the Dialogic devices.
You might need to disable Dialogic devices for any of the following reasons:
Q Disable devices to allow non-TeleVantage applications to run on the TeleVantage
Server.
For example, you may have another telephony application installed on the
TeleVantage Server that must own some Dialogic devices. You would identify the
specific Dialogic devices and channels required by the application, and then disable
those devices. When TeleVantage opens Dialogic devices at startup, it will ignore the
disabled devices, making them available to the application.
Note:
You do not need to reserve devices when developing an IVR Plug-in, which will
automatically share TeleVantage’s Dialogic resources as needed.
Q Disable devices to connect a fractional T1 or E1 line to TeleVantage. For example,
you may have a T1 line with 12 channels instead of 24. To connect this T1 line to
TeleVantage, you still connect it to a Dialogic board with 24 channels, but you disable
half of the channels. When TeleVantage starts, it will see 12 instead of 24 trunks, which
will match the fractional T1 line. You must be sure to disable the correct half, for
example, trunks 1-12 or trunks 13-24, whichever matches the fraction of the T1 line you
have.
Q Disable devices to ignore several trunks on a telephony board and use its voice
resources only.
For example, you could install a D480SC-2T1 card that supports two
T1 lines (even though you only have one T1 line) and 48 voice processors in one slot.
The D480SC-2T1 card has 24 extra voice resources that you can use to provide dial tone
and voice prompts for those 24 stations. Installing a D240SC-T1 card (that supports only
one T1 line) and another board that provides the additional 24 voice resources would
consume an additional slot. For this configuration, you would disable the T1 resources
for the second T1 line on the D480SC-2T1 board. TeleVantage will not see the disabled
T1 resources when starting up, but it will see all the voice resources.
To disable Dialogic devices in the Windows registry
1. Using the conventions described in “Dialogic device names” on page J-24, determine
the device names for the Dialogic devices you want to disable.
2. Run
Regedit.
3. Create the following key as a string value (if it does not already exist):
HKLM\SOFTWARE\Artisoft\TeleVantage\Server\Settings\DisableDevices
