  3. Introduction • Panasonic introduces the New KX-TDE100/200 Pure IP PBX range. • Panasonic KX-TDE100 and KX-TDE200 Pure IP PBXs are advanced corporate communication systems providing IP telephony features and functionalities over both local and broadband IP networks. Empowered with the latest SIP technology and packed with extensive productivity applications, the KX-TDE100/200 IP-PBXs: • Enable cost-effective IP telephony over local and broadband IP Networks • Support integrated SIP Desktop and Network Connectivity • Streamline and centralise corporate communications • Provide desktop mobility • Increase user and business productivity, and • Ease installation & maintenance • The system is highly modular and supports analogue, Digital & ISDN, SIP Trunks & Extensions, and Networks with other systems, making it ideal for customers planning to expand into a Voice Over IP (VoIP) Solution at their own pace. • Empowered with the latest SIP technology; the new KX-TDE100 and KX-TDE200 IP PBXs are an ideal communication platform for customers to help them solve all their business telephony needs today as well as in the future as they embrace full IP telephony.

  4. Panasonic New IP PBX All-in-One Converged IP Platform New IP Platform, Traditional Telecom Interfaces, and all TDA Solutions are converged into one system. It is a true converged system for today and the future. Smooth Migration Path for TDA user Easy/Smooth Migration is the key for converged systems today. All current TDA user can easily upgrade to a TDE system by simply replacing the current Main Processor (MPR) card with the new TDE MPR Card (IPCMPR). Easy Installation and Management Same programming method as current TDA system. Unified programming for IP and Traditional communication setup TDE New IP Features: Up to 64 IP-PT’s, and 32 IP-Trunks available with Optional DSP Board Up to 128 Standard SIP (RFC3261) Phones Fully equipped KX-TDA Functions and Solutions Easy Maintenance using PC Program and 2 Built-in LAN Ports Multi-site Programming (Up to 4 sites) New IP-PT Line-up with Bluetooth, Self Labeling keys & peer-to-peer communications Built-in Simple Voice Mail (SVM) KX-TDE Product KX-TDE100 KX-TDE200

  39. VoIP DSP Calculations – 1/6 • VoIP DSP capacities are calculated by a combination of: • The available DSP processing power • The available communications paths through from IP interface to traditional telephony interface (Limited to 49 paths on both TDE100 and TDE200), and • The available paths through any interconnecting IP trunks (Max 32 IP Trunk Paths) • There are three compression codecs available - G711; 64Kbps, G729; 8Kbps and G722 (HIFI AUDIO) • Note: G.722 only works in Peer to Peer Mode. • It uses processing power of the IP-PT and does not require any additional DSP resources on IPCMPR card. • G.729 8Kbps has the lowest network utilisation but it also has the highest processor utilisation (DSP) Voice Codec Converter DSP G.711 G.729
