Preparing Dialogic PCI Linecards for Installation
Depending on the linecard you are installing, you will need to configure some or all of the
following components of the Dialogic PCI linecard before installing it in the OneBox
platform.
•
Assign a linecard identification number based on the ports it will provide.
•
Configure the linecard to use an SCbus clock (except on the D/120JCT-LS model).
•
In the case of the D/41EPCI and the D/120JCT-LS, configure its default line state.
•
If the platform has only PCI expansion slots, remove the slot retainer brackets from
the linecards.
Assigning the Linecard Identification Number
Each Dialogic linecard installed in the OneBox platform must be configured with a
unique linecard identification number (referred to by Dialogic as the Board ID, Board
Locator ID, or Board Locator Technology ID). This number, from 1 through F hex (1–15
decimal), is used by Dialogic System Software to determine which linecard is sending a
signal. If two or more linecards installed in the platform are configured to use the same
linecard identification number, the Dialogic System Software (device driver) will be
unable to locate either linecard.
Unique linecard identification numbers must be assigned
in ascending order to each linecard starting at 1
.
OneBox assigns line numbers in ascending order based on the linecard identification
number. For example, if you install a D/240PCI-T1 linecard to which you have assigned
linecard ID 1, the 24 channels it provides will be assigned by OneBox the line numbers
1–24. If you then install a D/41EPCI to which you have assigned linecard ID 2, the four
ports it provides will be assigned the line numbers 25–28.
Precedence in Mixed Systems
D/240PCI-T1 linecards must be assigned the lowest linecard identification numbers of
any linecards installed in the platform starting at ID 1. The D/240PCI-T1 will not
function properly if another model of PCI linecard, such as a D/41EPCI, is assigned a
lower linecard identification number. For example, if you are adding two D/240PCI-T1
linecards in a platform that currently has two D/41EPCI linecards, the D/240PCI-T1
linecards must be assigned ID 1 and ID 2, and the D/41EPCI linecards must be changed
to ID 3 and ID 4.
