With the configuration settings shown above the IPAC-X in intelligent NT applications
provides for equal access to the D-channel for terminals connected to the S-interface
and for D-channel sources on IOM-2.
For a detailed understanding the following sections provide a complete description on
the procedures used by the D-channel priority handler on IOM-2, although it may not be
necessary to study that in order to use this mode.
