The Italtel Media and Signalling Gateway for IP-TDM Networks Interconnection
Moving to all-ip challenge While VoIP networks are evolving and increasing more and more, on the other hand, TDM assets are predominant in the networks of medium/large operators and their relative replacement will still take a long time. Similarly most of large/medium enterprises are renewing their infrastructure toward all-ip in order to take advantage of the enhanced features based on Unified Communication solutions. Even so, a lot of TDM devices like small Local Exchange, is the Italtel Media and Signalling Gateway providing high density transcoding services for IP-TDM interconnections ISDN PBX, Fax, are still present in their networks and have to be integrated (if possible) with the more recent and innovative platforms IP-based. Italtel, aware of this need and with a long and great experience within Media and Signalling Gateway, has designed, a compact, very flexible and powerful platform able to interface traditional installed platforms, TDM based, with the more innovative IP infrastructures. Saving the investment Service Providers and Enterprises which have completed the process of innovation of their network, replacing or dismounting the previous TDM infrastructure with all-ip, can take advantage of the investments previously done., in fact, has been designed to evolve toward a Border Gateway (NetMatch-B) reusing the same hardware and with a simple SW update. Product overview is the Media and Signalling Gateway within the NetMatch product line, designed to make easier the TDM adaptation toward any kind of IP Multimedia Interconnection. The is feature-rich, deployable with or without: equipment protection additional computing capacity according to the customer needs. In addition it can be deployed as VoIP gateway supporting low to medium channel densities. : Emerson Centellis and UCEMEP ATCA board High Availability VoIP Gateway The has compact footprint (3U) and low power consumption; it can meet the needs of both service providers with networks geographically distributed, as well as large enterprises. uses the latest generation of advanced, all-in-one DSPs and platform architecture, for high quality VoIP and fax/modem handling. simplifies the transition to VoIP with any-to-any voice and multimedia interconnections IP to IP, IP to TDM, TDM to TDM;
is targeted for interconnecting IP and TDM Networks providing Media Gateway and Signaling Gateway functionality, but it is futureproof interoperable because it is ready to be transformed in a Border Gateway simply by means of a SW configuration change Product characteristics Low to mid-density VoIP gateway able to scale from 2000 to 8000 channels; Supports high availability configuration with reliable 1+1 redundancy; Compact footprint (3U), ideal for small locations Allows easy capacity upgrades via a software license key H.248 controlled both by Italtel imcs (Italtel Multimedia Communication Suite) and by third party SSWs Both STM1 and E1/T1 PSTN Interfaces Wide range of vocoders which include Low Bit Rate (LBR), wireline, cellular and wideband vocoders Signaling backhauling capability for both SS7 and ISDN PRI signaling links Evolution toward IMS Border Gateway (I- BGF functionalities) IPv4/IPv6 dual stack support HD voice and video (Border Gateway only) Security Local management via CLI / web interface Complete Network Management System through Italtel Network Element Manager (i-nem) 3.
