2.2.1 - Basic ISDN Connections
If this IOLINK-520 & IOLINK-PRO are configured as an ISDN bridge/router, it may
establish WAN connections to other bridge/routers via ISDN (Integrated Services Digital
Network) connections.
Before the IOLINK-520 & IOLINK-PRO can establish an ISDN connection to another
ISDN router, the ISDN information must be defined. The ISDN switch type must be
defined for the ISDN interface, and the phone numbers must be defined. Refer to the
following diagram that shows three IOLINK router units connected together with two
ISDN B-channels being configured on each unit.
