DIVA Pro 2.0 ISA Adapter

UnixWare 7 supports the DIVA Pro 2.0 ISA Adapter.

To complete configuration for this adapter, the Network Configuration Manager prompts you for:

Interrupt Vector (IRQ)
I/O Address
ISDN Address (B-channel 1 and 2)
Specify your Local ISDN Number. This information is provided by your ISDN service provider.
ISDN Subaddress (B-channel 1 and 2)
If two local terminals share the same ISDN Number, enter a Local Subaddress to further identify the terminal on the ISDN Basic Rate Interface (BRI). Subaddresses provide an additional addressing capability outside of the ISDN numbering plan. Subaddresses are transparent to the public network. For example, a subaddress can be used to identify a particular station on a Private Branch Exchange. A Local Subaddress is not always required and is defined by the user.
Service Profile Identifier (SPID) (B-channel 1 and 2)
Only applies to the ISDN protocols NI-1 or AT&T 5ESS Custom. Specifies the SPIDs that the driver uses to communicate with the ISDN switch. Your ISDN service provider assigns the SPIDs for the ISDN line. For the proper SPID values, refer to the documentation provided when you ordered your ISDN line, or contact your ISDN service provider.

NOTE: SPID values are not always required by your ISDN service provider for the AT&T 5ESS Custom Protocol.

Layer 2 Mode - D-channel Connection
This setting controls the type of ISDN D-channel/Layer 2 connection.
Normal operation: The D-channel/Layer 2 connection is maintained only while there is a B-channel connection to a remote system.
Never deactivated: The D-channel/Layer 2 connection is activated when the initial B-channel connection is made and is maintained until the DIVA software is stopped.
Always active: The D-channel/Layer 2 connection is set up immediately and maintained.
TEI Value Assignment - Terminal Endpoint Identifier (TEI)
The TEI value enables data in the ISDN control-channel to be assigned for the logical connection between ISDN network termination (NT) and ISDN device. With the parameter TEI the ISDN card can be configured for automatic issue of the TEI value or a fixed value can be assigned to it.
The following values can be assigned for the TEI:
- Dynamic - a TEI value is automatically assigned by the ISDN network termination (NT).
- 1-63 - for nonautomatic TEI assignment user equipment.
