Transmission Performance Metrics Based on Error Correction Mode (ECM) Facsimile - Series E: Telephone Network and ISDN Quality of Service Network Management and Traffic Engineering - Network Management - Checking the Quality of the International Telephone
The purpose of this Recommendation is to define transmission performance metrics based on Error Correction Mode (ECM) facsimile. Performance parameters defined in Recommendations E.45 1, E.452 and E.453 have been modified to accommodate the error correction and Partial Page characteristics of ECM facsimile. Performance parameters for ECM that will help estimate the image quality for non-ECM transmissions have also been defined.
