It's not clear what the question is but anyway....

The descriptions above are accurate to a first approximation. However, the ISDN
label is applied to a whole basket of bits of technology, for instance not all
are protocols - some are the services that the network provides. The protocols
in the wire have some similarities with other protocols such as ethernet but
ISDN has a more complex call set-up process associated with the low-level
protocols in order to set-up a point to point connection for a specific class of
service.
