Answer Supervision
Description
The Hybrex Series Digital Telephone System is equipped to provide answer supervision in applications
where it is provided by the telephone company as a polarity reversal. When active, answer supervision
provides accurate timing information for the preparation of SMDR records within the system.
Conditions
Answer Supervision will operate only if it is being provided by the local telephone company.
Programming
Mode 14-01-01 (Recording Start Time) should be set to [0] in order to allow the system to accurately
expect answer supervision, if available. If answer supervision is not provided by the local telephone
company, this parameter should be set to a time that is representative for a call to be placed. For more
information, please see Station Message Detail Recording, page 160 of this document.
Mode 14-01-08 (Detect Polarity Reversal) must be set to [0], disable, in order to recognize answer
supervision by polarity reversal. (Polarity reversal is not for NZ so set to 0).
Operation
Operation of Answer Supervision is automatic.
