ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 85

7-45

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.
