Hardware Installation and Setup
1)
Configure the Jumper Settings
Please refer jumper setting for details. To install B400P, user should
follow the steps.
A.
Setting Card ID Switch
If user wants to install more than one cards of B400P in one pc, you
should take care of the card id switch. It has three rules, which user
must follow:
1.
The card id of the first card must be set to 0, and the second card
should be set to 1, and so on.
2.
The First Card is a card that will be initialized (i.e installing
driver) first when system is booting.
3.
At most of cases, Linux will initialize PCI devices according to
PCI slot order. The slot is nearest to the CPU will be initialized
first; the slot at the far end from CPU will be initialized at last.
That is to say, if user has more than one cards of B400P in pc, the
one is nearest to CPU should be set to card id 0.
B.
Adjusting Termination of S/T Interface (100 ohm)
1.
If a port will work on NT mode, you should set jumper to CONNECT
(ON).
2.
If a port will work on TE mode, Theoretically it should be to
OPEN(OFF), but user might connect to some non-standard isdn
terminal equipments that do not have terminal resistors, for such
equipments, you should set it to CONNECT(ON).
C.
Power Feeding Connector
These jumpers control whether the card will feed power to the external
isdn terminal. User should adjust accordingly.
If the port will work on TE mode, user MUST set the jumper to
OPEN(OFF)
If this port will work on NT mode, the ISDN terminal requires
ISDN power supply, user should set the jumper to CONNECT(ON).
ISDN terminal does not require ISDN power supply, user should
set the jumper to OPEN(OFF).
