New OIF Project Maps TFI, TDM Signals.Carriers Highlight Importance of Forum Work in ASON ASON Automatic Switched Optical Network (Lucent) Network Deployments FREMONT, Calif. -- Enhanced interoperability between CEI-P Devices and TFI/TDM-P clients is the aim of a new technical project announced by the Optical Internetworking Forum The Optical Internetworking Forum (OIF) was organized to facilitate and accelerate the development of next-generation optical internetworking products. The OIF produces Electrical, Tunable Laser, Very Short Reach Hardware Interfaces. (OIF) at its final 2006 meeting in Dallas. The new project, known formally as TFI-5/TDM-P Clauses in CEI-P, is targeted for 2007 work by the Physical and Link Layer Working Group. The TDM-to-Framer Interface (TFI) series of interfaces and their aggregation layer TDM-Protocol (TDM-P) are important methods of transporting SONET/SDH and OTN TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. signals between devices. The CEI-P layer, a protocol layer for the Common Electrical Interface (CEI), was defined in early 2006 and allows the support of FEC on signals in a 64B/66B format. This new project aims to describe a mapping of the existing TFI and TDM-P interfaces over CEI-P. "This project will tie together three of the OIF's existing specifications and deliver Forward Error Correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. (FEC) protected links for Time Division Multiplex (TDM) backplanes," said Brian Holden, MA&E (Marketing Awareness & Education Committee) co-chair for the OIF. OIF Dallas meeting attendees flocked to a workshop entitled "ASON/GMPLS Implementations in Carrier Networks." Representatives from AT&T, Telecom Italia and Verizon discussed their experience with control plane implementations, highlighting the role and significance of OIF technical agreements in network deployments. The carrier reps also provided feedback to OIF members from practical experiences and future expectations.

Level 5 Phase 2 (SFI-5.2): Implementation Agreement for 40Gb/s Interface for Physical Layer Devices. This Implementation Agreement describes an interface between SERDES See serializer/deserializer. and Framer devices within the Physical Layer (Serdes Framer Interface or SFI). SFI-5.2 is an interface, based on 4 data lines plus de-skew channel, for aggregate data bandwidths of OC-768, STM-256, OTN OTU3, as well as other applications at the 40 Gbps data rate. The IA is available at http://www.oiforum.com/public/impagreements.html "SFI 5.2 is the latest generation of 40 Gb/s interface that is optimized to require fewer pins than prior generations. It allows 40 Gbps signals to be transported on a narrow interface between framers, FEC devices, and optical interfaces," said Physical Link Layer Working Group chair, David Stauffer of IBM. OIF Leadership Update OIF members elected a new board of directors for 2007/2008. In the board of directors election, the OIF membership elected Chuck Sannipoli of IP Infusion and former president of the Network Processing Forum The Network Processing Forum (NPF) was organized to facilitate and accelerate the development of next-generation networking and telecommunications products based on network processing technologies. The NPF was merged into the Optical Internetworking Forum in June of 2006. and re-elected Hans-Martin Foisel of Deutsche Telekom, Steve Joiner of Finisar, Stephen Shew of Nortel Networks and Vishnu Shukla of Verizon. Joe Berthold of Ciena and Monica Lazer of AT&T continue in their elected positions as part of a two-year term on the board. The board named Joe Berthold as president, Hans-Martin Foisel as vice president, Steve Joiner as vice president of marketing and Monica Lazer as treasurer/secretary. In addition, Lyndon Ong of Ciena was elected vice chair of the OIF Technical Committee and Jonathan Sadler of Tellabs was re-elected as the Architecture and Signaling Working Group chair. About the OIF Launched in April of 1998, the OIF is the only industry group uniting representatives from data and optical networking disciplines, including many of the world's leading carriers, component manufacturers and system vendors. The OIF promotes the development and deployment of interoperable networking solutions and services through the creation of Implementation Agreements (IAs) for optical, interconnect, network processing and component technologies, and optical networking systems. The OIF actively supports and extends the work of national and international standards bodies with the goal of promoting worldwide compatibility of optical internetworking products. Working relationships or formal liaisons have been established with the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3, IETF See Internet Engineering Task Force.
