Field 4 Translates ISDN trunk type 120 only. Recall that for ISDN applications the trunk
type may be translated as fixed (that is, one specific type) or dynamic (which may
include those from the fixed category). Generally, the trunk type selected will
depend on the network service or feature value, which is translated in field 5. Table
7-4, Network Service/Feature Options, shows the relationships.
