Isdn Information - BT Speedway ISDN PCI card Installation Manual

For Internet service providers offering PPP over ISDN (synchronous PPP
according to RFC 1618), both the ISDN CAPI Port Driver and the NDIS WAN
CAPI Driver are suitable. You should ask your Internet service provider
whether PPP over ISDN protocol is supported.
In the case of Internet service providers not offering PPP over ISDN, it is
normally possible to dial in via the CAPI Port modem PPP asynchronous.
With the ISDN CAPI Port Driver, it is also possible to support special
solutions by way of register settings. You should ask your Internet service
provider. Due to the system design, the NDIS WAN CAPI Driver does not
offer this functionality.
Both drivers are suitable for access to RAS servers and Non-Internet
applications such as MS Money 97 or terminal.

6.3 ISDN Information

The Speedway ISDN PCI Card may be connected to any suitable ISDN
termination. Typically this would be either ISDN2e or BT Highway. Network
Termination Equipment (NTE) will generally have two sockets available for
connection of the cable and either socket can be used.
Your ISDN service may have a number of MSNs (Multiple Subscriber
Numbers) associated and so it will be necessary during the installation phase
of the Speedway ISDN PCI Card to enter the MSN you require to operate with
your PCI Card.
All incoming calls from the ISDN are distinguished not only by their MSN but
also by their service indicator. No such differentiation takes place for calls
coming in from the analogue network, in which case voice, data and fax calls
share the same network service. This is why it is important to specify which
call is to be accepted with MSN by an application module or by an ISDN
telephone. Please refer to the Speedway! online help for further details.
If you wish to receive faxes as well as data with the Speedway ISDN PCI Card,
you do not need to assign different Multiple Subscriber Numbers to these
applications because Speedway! fax is responsible for calls with the voice
indicator and Speedway! data for calls with the data indicator. Speedway! fax
and Speedway! answer both use the same service indicator (voice). However,
if you use Speedway! fax at the same time as Speedway! answer, you must
allocate different Multiple Subscriber Numbers to the two modules in order
that incoming calls can be assigned without ambiguity.
