21. VMUX_TS2009.ppt - Slide 21 http://www.cbnetworks.fr - support.technique@cbnetworks.fr Features & Benefits Up to 16:1 voice compression ratio VAD & Silence Suppression Equipped with both TDM & IP uplinks Supports any type of signaling including CAS and CCS Transparent to all telephony features including: fax, modem, CLIP, IVR, MFC, etc. Compact, Scalable and Simple to deploy Maximum reduction of voice transmission costs No bandwidth consumed when channels are idle Seamless migration from today’s TDM networks to tomorrow’s IP networks NO compromise of existing telephony features and NO retraining of staff Minimizes Initial Investment & Collocation Costs

22. VMUX_TS2009.ppt - Slide 22 http://www.cbnetworks.fr - support.technique@cbnetworks.fr Advantages over standard VoIP Solutions (for trunking applications) TDMoIP multiplexing provides higher bandwidth savings (16:1) than any standard VoIP solution Full signaling transparency ensuring seamless integration with no retraining costs or lost functionality Provides bandwidth reduction even without migrating to IP networks Backup between IP and TDM uplinks with the same bandwidth savings Single compression cycle end-to-end (Super-Tandem) Better resiliency to packet loss Supports bandwidth control mechanisms to better cope with situations of bandwidth overflow

23. VMUX_TS2009.ppt - Slide 23 http://www.cbnetworks.fr - support.technique@cbnetworks.fr Bandwidth Considerations User configurable parameters: Voice codec used (between 5.3k & 64k) Packet size (tradeoff between bandwidth & delay) Packet type (AAL2oMPLS header - smaller than TDMoIP - for TDM networks only) Application dependant parameters: Number of compressed voice channels in a single bundle (The more channels, the less header overhead) Actual silence percentage (typically – 50% in fixed line networks, 35% in cellular networks) Easy to use calculator for case-by-case estimation of compression ratio
