TDMoIPTransport TDM circuits over IP and Ethernet networksEthernet and IP are changing the economics of data services delivery, bringing simplicity with lower cost to both carrier and enterprise users. TDM over IP (TDMoIP) takes advantage of this infrastructure to help carriers deliver high revenue leased line services such as E1, T1, E3 and T3. TDMoIP is also ideal for the enterprise looking to reduce network expenses without compromising features of their existing PBX and TDM equipment. This evolutionary approach maximizes investment protection by running all TDM traffic irrespective of protocols or signalling transparently over IP and Ethernet networks. The emerging technology of choice: TDM over IPTDMoIP is a transport technology developed by RAD that provides a simple conversion strategy to IP-based networks. TDMoIP carries E1, T1, E3 or T3 circuits across the packet-switched network, transparent to all protocols and signalling. TDMoIP enables service providers to migrate to next generation networks and continue to provide all their revenue generating legacy voice and data services. TDMoIP also benefits data carriers by enabling them to offer lucrative leased line and private line services. This lets them maximize revenues from their packet-switched (e.g., Gigabit Ethernet) infrastructure by selling voice services as well as data. It enables enterprises to run voice and video over the same IP/Ethernet-based network that is currently used to run only LAN traffic, thereby minimizing network maintenance and operating costs. How TDMoIP worksTDMoIP takes TDM data streams and converts them into IP packets (with an IP addressing scheme) for transmission over the network. The original traffic, including clocking, is regenerated at the destination. Transparent connectivity over the IP/Ethernet network maintains all features and functionality of the telephony network. TDMoIP therefore provides seamless migration of a variety of legacy services to packet-switched networks, with full support for legacy equipment such as Class 4 and 5 switches, PBXs and TDM multiplexers. RAD is working together with other industry leaders on the Internet Engineering Task Force (IETF) to standardize the TDMoIP protocol. A superior alternative to VoIPNot only is TDMoIP simpler and less expensive than VoIP, but it is also a superior alternative in many other ways especially in applications where the existing PBX functionality is sufficient. Most importantly, TDMoIP provides higher voice quality with much lower latency that VoIP. Unlike VoIP, TDMoIP can support all applications that run over E1/T1 circuits, not just voice. TDMoIP can provide traditional leased line services over IP, and is transparent to protocols and signalling. Because TDMoIP provides an evolutionary not revolutionary approach, investment protection is maximized. RAD's TDMoIP product solutionsRAD offers a variety of product solutions incorporating TDM over IP (TDMoIP) technology. These products include the IPmux family of TDMoIP gateways, the Megaplex family of multiservice access multiplexers and the Kilomux sub-rate multiplexer and voice compression device. The IPmux family of TDMoIP gateways transparently extends TDM circuits over IP and Ethernet networks. These products handle full and fractional E1/T1 and E3/T3 streams, supporting ToS (DiffServ) on the IP layer and VLAN on the Ethernet layer. Megaplex and Kilomux multiplexers, equipped with an internal TDMoIP main link module, work opposite the IPmux to function as full service TDMoIP gateways, providing over 50 I/O modules for voice, fax and data applications in ring, star and daisy-chain topologies. RADview Service Center TDMoIP is an SNMP-based network management system designed to manage TDMoIP gateways and provision leased line services in a quick, intuitive manner. Benefits of RADs TDMoIP products
Who benefits from TDMoIP? Utility companies reduce expenses and simplify their networks by migrating legacy voice and SCADA applications over their more efficient Ethernet networks Utelcos: generate new revenue by delivering profitable leased and private line services over their scalable Ethernet/fibre infrastructures. Incumbent carriers: reduce infrastructure costs by utilizing their IP cores for TDM transport (e.g., connecting SS7 over IP). Metropolitan carriers: with IP or Ethernet access networks generate new revenue by delivering traditional leased line and private line services such as E1/T1 and E3/T3. Cable operators: can generate new revenue by offering traditional E1/T1 leased line and private line services over their hybrid fibre coax (HFC) cable networks. Enterprises: reduce network expenses with maximum investment protection by running all TDM traffic over Ethernet. Popular TDMoIP applicationsCarrier:
