TIA TIA-1110 PDF

This standard provides handset acoustic performance requirements for Customer Premises Equipment (CPE) intended for connection to the Public Switched Telephone Network (PSTN). These requirements should ensure compatibility and satisfactory performance to the user in a high percentage of installations. Test measurement methods reference procedures in IEEE Std 269 where applicable.

Several performance measurement procedures are established today, each of which yields standardized measurement data that may be used for the comparison of different products. This document may reference only a single procedure or specific equipment, however the intent is not to be all-inclusive. Any measurement procedure and equipment that can result in an identical measurement is considered valid.

While the procedures may call out specific test points within the requirements, the full range of the requirements take precedent.
