PortMaster 3 T1/PRI Provisioning
In order for the PortMaster 3 to work correctly, you must supply your ISDN
service provider with specific ISDN setting information. This document suggests
the most common (default) configuration for ISDN PRI provisioning.
Your ISDN service provider will want to know:
One way or two way service?
One way service is for inbound calling only. Two way service
is for both in/outbound calling.

Circuit-Switched Data Only?
Alternating Circuit-Switched Voice and Circuit-Switched Data supports
ISDN and modem calls. Circuit-Switched Data only supports ISDN calls.
