PRODUCT BRIEF FEATURING VOICE SOLUTIONS L E79112 VOICE CONTROL PROCESSOR APPLICATIONS The Le79112 Voice Control Processor (VCP) is There are four firmware options offered for a digital signal processing platform that works the Le79112 VCP device: CO with the Legerity VE790 Series of chip sets LineCare Call Control Le79112SLNT using the MPI interface, PCM port, and an IVD interrupt line from the codec/filter. The LineCare Basic Test PBX Le79112SLBT primary functions of the Le79112 VCP are to LineCare Advanced Test program and control the codec/filter via an KTS Le79112SLAT Application Programming Interface (API). LineCare Advanced Test Plus Firmware residing in the DSPs RAM provides Le79112SLATP FEATURES enhanced call processing and test capabilities. The Le79112 VCP in combination with a Software interface using VE790 Series chip set, supports up to 32 VP API-II channels of universal telephone line interface with high-level voice functionality. The solution Software downloadable, enables the design of a low-cost, high- field upgradable, performance, fully software programmable line expandable interface for multiple country applications. All Provides expanded line of the AC, DC, signaling parameters, and data and circuit testing in are fully programmable via the Host Bus conjunction with Legeritys Interface (HBI) through the combination of the VE790 Series of chip sets HBI and a slave PCM port. DTMF detection Additionally, the Le79112 VCP has integrated Quad tone and howler tone self-test and line-test capabilities to resolve faults to the line or line circuit. The integrated generation Le79112 Voice Control Processor test capability is crucial for remote Arbitrary single tone applications where dedicated test hardware is detection not cost effective. 15-kHz energy detection SNR tests Dial pulse measurement SYSTEM BLOCK DIAGRAM Internal Balanced Ringing Le79228 TM SLAC Device Le79112 VCP codec 1 Le79252 SLIC Voice Signal codec 2 Device Processor codec 3 Le79252 Test SLIC Functions* codec 4 Device Microcontroller or External Unbalanced Ringing Le79228Rin Signal TM Backplane I/F SLAC Device Le79232 Le75282 codec 1 SLIC LCAS *Test Function Measurements: Device optional Voice Signal codec 2 Voltage Processor Current Le79232 codec 3 Le75282 Resistance Test SLIC LCAS Capacitance Functions* optional codec 4 Device Tone Noise VCP Application Board SLAC devices are also available in 2-, 4-, and 8-channel versions. www .Legerity .com PCM HighwayLineCar e Call Contr ol Softwar e Major Call Control Features The VCP Package HOST CONTROLLER 32-Channel Call Control Control/Coordination of Call Processing HOST CODE CID high level interface HOST ALGORITHMS Document and source code for high-level algorithms Control for Metering DTMF Detection API-II SOFTWARE Up to 16 lines simultaneously Application Programming VP API-II Interface (API) that presents a Q.24 compliant unified programming interface to Pulse Dial Timing with Decode all of Legeritys Voice Termination 32 simultaneous channels Devices (VTD) Adjustable timing parameters for Make, Break, Flash, and VCP FIRMWARE HBI Control aggregation Disconnect DTMF Detection VOICE CONTROL PROCESSOR Zero-Cross Detection for ringing on/off control Line Testing Pulse dial timing Optional make-before-break, or break-before-make (with LCAS) Zero cross detection MPI Adjustable delays for internal ringing CID AC and DC fault detection with automatic disconnect of the line SUPPORTED LINE CIRCUIT CONFIGURATIONS Slow ramp from Disconnect to Standby Programmable ramp time (0-4000ms) QISLAC QISLAC Read loop conditions while in service VoicePort Line Current (Metallic and Longitudinal) Le79232 SLIC Le79252 SLIC 2-CH ABS Sensed Voltage EMR*/LCAS Current battery supply voltages Howler Tone generation 790 Series 790 Series 880 Series External Ringing Internal Ringing Line Configuration Minor Call Control Features * Optional Loadable Image Field firmware updates (compressed image support) Programmable on/off for each fault type Automatic switch to Active (Talk) on ring-trip/off-hook Minimizes the delay for ring-trip no host interaction needed Automatic Ringing and Metering Cadencing RELATED COLLATERAL Smooth polarity reversal control AVAILABLE ON WWW.LEGERITY.COM Checksum over Program Code space while in-service VCP Basic Test Product Brief ( 081332) VCP Advanced Test Product Brief ( 081333) VCP Advanced Test Plus Product Brief ( 081334) FEATURING VCP Configuration A (External Ringing with LCAS) ( 081051) VOICE SOLUTIONS VCP Configuration B (Internal Ringing with Legerity was acquired on August 3, 2007 by Zarlink Semiconductor and was Test-Out Bus) ( 081168) incorporated into the Wired Communications product group which also includes Zarlink s timing, synchronization, voice processing and hands free products.
