Dear Colleague, TDMoIP Becomes Industry-Wide Standard
The International Telecommunications Union (ITU) has recently adopted two recommendations that, in effect, turn TDMoIP from a de facto into a de jure industry standard. Recommendation Y.1413, which RAD has implemented in its IPmux product line, specifies TDMoIP as one of three standardized modes for supporting constant rate TDM services over MPLS networks. Recommendation Y.1414, which RAD has implemented in its Vmux product line, specifies TDMoIP as one of three standardized modes for supporting variable rate voice services over MPLS networks. Y.1413 and Y. 1414 are two of the ITU's Y.14xx series of recommendations that cover multiservice internetworking. RAD is an active participant in ITU-T Study Group 13. In addition, TDMoIP is defined in IETF (Internet Engineering Task Force) Internet Drafts, soon to be issued as Requests for Comments (RFCs). Furthermore, RAD was the first vendor to announce product compliance with two Implementation Agreements (IAs) issued by the MPLS/Frame Relay Alliance. IA 4.0 covers transport of constant rate TDM services, and IA 5.0 covers variable rate voice services. Parallel processes in other institutions, such as the Metro Ethernet Forum, have similarly included TDMoIP as a standardized mode of operation. "In the past, it had been true that VoIP had industry-wide standardization in its favor, while TDMoIP was lacking in that regard," stated Dr. Yaakov Stein, Chief Scientist at RAD Data Communications. "With these recent developments, however, VoIP and TDMoIP are on a par in terms of standardization," Stein continued. "VoIP can claim the ITU's H.323 suite of protocols, but TDMoIP can now respond with Y.1413 and Y.1414," he explained. "In the IETF VoIP has the SIP and RTP RFCs, but TDMoIP's replies are Internet drafts that are on track to become RFCs in the near future," Stein added. "Standardization should no longer be an impediment to TDMoIP deployment."
RAD also conducted a separate demonstration at SUPERDemo of E1/T1 and LAN service over E-line services. An IPmux-11 TDMoIP multiservice gateway, designed for deployment at the customer premises, was used to transport both VLAN and CES traffic over an E-Line cloud to RAD's carrier-class Gmux-2000, a soon-to-be-released TDMoIP product designed for deployment at points-of-presence (POPs) and central offices. By assigning different VLAN tags to voice and data, the IPmux-11 illustrated how economical E1/T1 services can be added to metropolitan Ethernet networks using a one-box solution at the customer premises. The Gmux, moreover, will serve to transform TDMoIP into a true carrier-class service. Earlier this year RAD unveiled its RJ020 ASIC, which it is using to power the next generation of its Ethernet network termination units (E-NTUs) and TDM over MPLS access devices. To date, 20,000 TDMoIP ports have already been shipped, and investment analysts at Piper Jaffray & Co. estimate that by 2006 that number will have grown tenfold to 200,000.

Sincerely, |
TDM over IP (TDMoIP) technology, developed,
patented and introduced to the market by RAD Data Communications and
implemented in its IPmux series of TDMoIP gateways and Vmux series
of voice trunking gateways, has taken the industry's center stage as
a standard for running legacy services - primarily leased line and
bulk voice - over next generation packet switched
networks.
Needless to say, TDMoIP is attracting
widespread interest at industry exhibitions and interoperability
events. At SUPERDemo, for example, which was held under the auspices
of the Metro Ethernet Forum (MEF) at SUPERCOMM 2004 in Chicago, RAD
joined forces with TranSwitch Corporation in demonstrating circuit
emulation system (CES) interoperability using TDMoIP technology over
an MEF-compliant Ethernet UNI service. The demonstration teamed
RAD's IPmux-16 TDMoIP gateway with TranSwitch's PacketTrunk-4
internetworking gateway, and focused on transporting voice and E1/T1
TDM traffic over an Ethernet UNI network, powered by TranSwitch's
scaleable Envoy family of carrier grade Ethernet controllers and
aggregators. The demo featured advanced traffic management
capabilities, such as voice prioritization, service provisioning and
the efficient and fair handling of bursty data traffic.
PacketLight Networks, a developer of SAN-over-SDH/SONET
solutions, has joined the RAD Group as its fifteenth member company.
France's Distributique magazine, part of the

Dynetcom enabled Teleperformance to achieve a notable reduction in
communications costs and "considerably augment call capacity without
requiring investment in new equipment."
