| Design-In Guide for JADE AN Audio Ringing Codec Filter Basic Function PSB 7230 08/97 The PSB 7230 Joint Audio Decoder Encoder for Analog Videophones (JADE AN) is a device wich implements voice compression algorithmus using the Algebraic Code Excited Linear Prediction (ACELP) and the Multi-Pulse Maximum Likelihood Quantization (MP.MLQ) standard as defined in the ITU-T G.723 Recommendation. 1. Potential application * * * * ISDN and analog Videophones Corporate Nerwork voice concentrators, multiplexers and gateways Data-over-voice and Voice-over-Data terminals Digital Added Main-Line (DAML) & Digital Circuit Multiplication Equipment (DCME) 2. Features: * G.723 V5.1 (6.3, 5.3 kbps)and G.711 (64 kbps) Compression/Decompression * Uncompressed/compressed audio switchable between different interface combinations (IOM(R)/Serial Audio Interface, IOM/Host) * Inbanc controlled H.221/H.223 oriented audio protocol, e.g. for direct serial connection to Videotec (VPC of 8x8 Inc., formerly IIT Inc.), as well as host based solutions * Stable reaction on interrupt handshake timing violations of e.g. a slow host (Windows PC) * Outband controlled audio protocol with optimized data rate * IOM-2 Monitor and C/I channels * 4-line IOM-2/PCM and 5 line Serial Audio Interface, e.g. for connection to Videocodec H.221/223 processor * Programmable via Parallel Host Interface * Access to audio channels and serial transparent data controller from DSP or an external Host * Interface to external software via a full-duplex 64-byte on-chip mailbox * Operating parameters and mode settings via a register bank * Supply voltage :3.0-3.6V * Advanced 1- BICMOS technology 3.
