Automatic Intercept System: Organization and Objectives

Abstract

The Automatic Intercept System routes calls to nonworking telephone numbers to a centralized location where a time division network under stored program control connects the calling customer to a series of prerecorded announcements. The customer is told what number he reached and, from information stored in a large‐capacity disc file, is given the reason the number is not in service and, if available, the new number at which the called party may be reached. This paper describes the system objectives and organization and also serves as an introduction to the detailed papers which follow.

Automatic Intercept System: Administering the Intercept Data Base

“…When this is done the system is made tem porarily insensitive to the expected flurry of not-in-file indications since their normal handling would cause flooding of the centralized intercept bureau operator positions. 1 It may be found in normal operation of some AICs that occasionally a region of the file becomes so congested that insertion of new entries requires abnormally long times to complete all the data rippling required to maintain ordering within thousands groups. To relieve such congestion it is possible to do some restructuring of the data base.…”
