AT&T 555-230-520 manual Call Denial Vector Commands, Call Denial Vector Command Qualification

Functions and Examples

If the receiving switch decides it is unable to accept the Look-Ahead Interflow call, call denial is accomplished by executing either of the vector commands listed in the following table. One recommendation: use busy instead of disconnect to allow for compatibility with similar network services such as ADR.

Table 8-2. Call Denial Vector Commands

Call Denial
Vector Command	Qualification
busy	■	Always
disconnect	■	With no announcement

■ With announcement but announcement unavailable

The vector commands presented in the next table are considered neutral because they do not generate either call acceptance or denial messages.
