Overview of ISDN BRI Connections
12-2 PortMaster Configuration Guide
For the ISDN S/T interface, a PortMaster requires an external terminal adapter to
connect from the PortMaster synchronous port to the ISDN link. For terminal adapters
that do not have automatic dialing or for administrators who want to manually connect
with the terminal adapter, the PortMaster supports automatic location table scripting.
For more information, see Chapter 8, “Configuring Dial-Out Connections.” For more
information about configuring the PortMaster for ISDN with an external terminal
adapter and automatic location table scripting, refer to Chapter 14, “Using Synchronous
V.25bis Connections.”
ISDN BRI ports can provide the same services that an asynchronous port provides,
except for direct network hardwired connections. The PortMaster automatically detects
whether the port is providing asynchronous or synchronous, 56Kbps or 64Kbps.
ISDN BRI connections can be initiated as needed, or they can remain active
continuously. A dial-out location must be specified in the location table for dial-out
connections, and a dial-in user must be specified in the user table or RADIUS for
dial-in connections. Figure 12-1 shows an example of an ISDN connection.
You can use PAP and CHAP for dial-in and dial-out authentication.
Contact your service provider for specific information about your ISDN switch type and
service profile identifier (SPID).
The following ISDN-specific settings need to be configured for each ISDN BRI port on
the PortMaster to permit ISDN service:
• ISDN switch type
• SPID—U.S. ISDN only
• Directory number (optional)
