(AN4) Testing CAS Detector Performance with the AI 240
All CPE’s that provide the capability to handle Type II Caller ID messages, also termed as Caller ID on Call Waiting, require a CAS tone detector. The detector’s purpose is the proper recognition of the CAS tone in the possible presence of voice or other signals. The ability of this detector to reliably detect the CAS tones is key to the proper operation of the CPE.

(AN3) Using External and Isolated DC Feeding Bridges
This application note outlines how to construct a simple DC feeding bridge for use with the AI 150/120 Caller ID Simulators, and the AI 240 CAS Test System. In most cases, the internal feeding bridge in the AI150/120 and AI 240 provides enough flexibility to meet the user’s requirements. However, an external and isolated DC feeding bridge can be very useful in at least two situations.

(AN2) Verifying CAS Test System Performance Using The CAS2200 Software
This application note outlines a procedure for verifying the performance of the AI 240 CAS Test System using the CAS2200 software. The AI 240 undergoes an extensive computerized testing and alignment procedure at the factory and normally should be re-calibrated at an interval of one year. However, sometimes it is desirable to perform more regular checks of key operational parameters at the user’s location without a large amount of sophisticated test equipment. This application note describes such a procedure.

(AN1) Verifying Caller ID Simulator Performance Using The CID1500 Software
This application note outlines a procedure for verifying the performance of the AI 150 Caller ID Simulator using the CID1500 software. The AI 150 undergoes an extensive computerized testing and alignment procedure at the factory and normally should be re-calibrated at an interval of one year. However, sometimes it is desirable to perform more regular checks of key operational aspects of the simulator at the user’s location without a large amount of sophisticated test equipment. This application note describes such a procedure.
