Adding ISDN devices

Configuration parameters

To configure your ISDN adapter, you must supply values for interrupt vector and I/O address that do not conflict with other devices on the system. The Network Configuration Manager supplies rational default values.


NOTE: You cannot use the Device Configuration Utility to set configuration parameters for networking devices.

In addition, for each B-channel you want to use, you must supply values for:


ISDN address
your ISDN number, supplied by your ISDN provider

ISDN subaddress
Optional. Two local terminals can share the same ISDN number by using a local subaddress to identify each terminal on the ISDN Basic Rate Interface (BRI). Subaddresses provide an additional addressing capability outside of the ISDN numbering plan and are transparent to the public network. For example, a subaddress can be used to identify a particular station on a Private Branch Exchange (PBX). Local subaddresses are not always required and are defined by the user.

SPID
Service Profile Identifier. If your adapter conforms to the North American AT&T 5ESS or National ISDN 1 (NI-1) standards, you might be required enter a SPID value. The SPID usually consists of the ISDN line number with a suffix and prefix used to identify line features required by your ISDN provider's switch. If required, the correct SPID values should be supplied by your ISDN provider.

SPIDs are currently used only for circuit-switched service, not packet-switched.


Line direction
Both incoming and outgoing calls are enabled by default, although you can disable either for special purposes. When incoming calls are enabled, the ISDN port monitor isdnmon(1M) listens for incoming calls. When outgoing calls are enabled, your ISDN adapter is listed in the Devices(4bnu) file and is accessible to the ISDN dialer, isdndialer(1M).
