Post Dial Delay (PDD) is experienced by the originating customer as the
time from the sending of the final dialed digit to the point at which they
hear ring tone or other in-band information. Where the originating
network is required to play an announcement before completing the call
then this definition of PDD excludes the duration of such announcements.
The Average Call Duration (ACD) is calculated by taking the sum of billable
seconds (bill sec) of answered calls and dividing it by the number of these
answered calls.
Answer Seizure Ratio is a measure of network quality. Its calculated by
taking the number of successfully answered calls and dividing by the total
number of calls attempted. Since busy signals and other rejections by the
called number count as call failures, the ASR value can vary depending
on user behavior.
