Indicates whether a table column is part of an index key value and whether its value can be 

NULL. Each column can be part of more than one index. 
Each index can consist of one or more key fields. The database recognizes four types of keys: 
PK: Primary key. The unique identifier for the row within the table. 

This is the key most commonly used to access a row. 
AK: Alternate key. Another unique key that identifiers the row. 
IE: Inversion key. A non-unique key within the row.
FK: Foreign key. A copy of a key from another table which can be used to reference that table. 
Alternate and inversion keys are numbered sequentially within each table. When two or more 

fields share the same designation (for example, IE1) the combination of those fields make up a 

single key. All non-key fields can have the value NULL unless explicitly noted otherwise. Key fields 

are always designated as NULL (that is, the NULL value is allowed) or NOTNULL.

A value that ICM software returns to a routing client. The routing client can map the label either 

to an announcement or a trunk group and DNIS value. The routing client then either plays the 

announcement or delivers the task to the trunk group along with the DNIS value. Special labels 

might instruct the routing client to take another action, such as playing a busy signal or an 

unanswered ring to the caller.

The number of route responses returned to the routing client that exceeded the late threshold but 

did not timeout. A routing response includes a destination label that indicates a specific target for 

a task. 
A routing client sends routing requests to the ICM software. The requests include a late threshold 

(or time limit) for the ICM software's response. A routing client typically corresponds to a 

subsystem within an interexchange carrier or to a peripheral (ACD, VRU, PBX) that is performing 

Post-Routing. In WebView, you can report on statistics for the different routing clients defined in 

the ICM system. For example, you might want to report on the maximum delay of route 

responses to the routing client for a specified interval.

The time limit imposed by the routing client (for example, IXC) for receipt of a routing response.
