interpreted as follows:
•For asynchronous terminal
lines, async network interfaces,
and virtual async interfaces, the
value is 00ttt, where ttt is the
line number or async interface
unit number.
•For ordinary synchronous
network interfaces, the value is
10xxx.
•For channels on a primary-rate
ISDN (Integrated Services
Digital Network) interface, the
value is 2ppcc.
•For channels on a basic rate
ISDN interface, the value is
