Trillium Digital Systems Inc. Announces First Commercially Available Source Code Software Supporting Q.933 Frame Relay SVC NNI Interface.LOS ANGELES--(BUSINESS WIRE)--Sept. 23, 1997--Trillium Digital Systems Inc., a leading provider of communications software solutions, Tuesday announced the release of the first commercially available Frame Relay Switched Virtual Circuit See SVC. switched virtual circuit - virtual circuit (SVC (1) (Switched Virtual Circuit) A network connection that is established at the time the transmission is required and disconnected when the session is completed. ) Network-to-Network Interface (NNI) signaling source code software. SVCs provide dynamic, on-demand connectivity which allows businesses to cut costs and manage bandwidth use. On-demand bandwidth features allow for greater scalability and lower costs compared with Permanent Virtual Circuit See PVC. (networking) Permanent Virtual Circuit - (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down. (PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. ) leased-line services. With the continued rapid growth of communications, carriers can use SVCs to provide a greater range of Quality of Service (QoS). Trillium President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. Jeff Lawrence said, "Trillium is committed to providing the broadest range of products to our customers. The addition of NNI functionality to our Q.933 software product demonstrates our commitment to being first to market with new technologies. "We are an active participant in the Frame Relay Forum and the ITU (International Telecommunications Union See ITU. (body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. ) to help our customers prepare for emerging technologies. At Networld + Interop in Atlanta this October, several Trillium Q.933 software product licensees will give demonstrations at the Frame Relay Forum SVC Technology Tour." Frame Relay NNI builds on User Network Interface (UNI) functionality, adding support for operations at the network side in a Frame Relay switch. It provides SVC and soft permanent virtual circuit (SPVC SPVC Soft Permanent Virtual Connection SPVC Switched Permanent Virtual Circuit SPVC Security Policy Verification Committee SPVC Soft Permanent Virtual Circuit ) signaling support as specified by the ITU X.76 recommendation and the Frame Relay Forum FRF FRF The ISO 4217 currency code for the French Franc. .10 implementation agreement. Trillium's standards-based implementation of NNI provides SVC establishment on Frame Relay links across networks, facility information signaling, and SPVC support. SPVC support eases Frame Relay VC administration within the network and allows for interconnection with existing users. Trillium's integrated Q.933 and Layer Management Interface (LMI) software products will now support SVCs and PVCs on the same interface for the UNI and NNI. In conjunction with its Q.922 product, which supports both the Core Aspects and the Link Access Procedure F (LAPF) reliable data transfer procedures, Trillium's Q.933 and LMI software products provide a complete, end-to-end Frame Relay stack solution for operation at both the user and network sides. All the capabilities are configurable per port/interface at run time. These features provide complete flexibility to support various signaling specifications. Trillium's Q.933 NNI capability is fully compliant with the ITU-X.76 recommendation and FRF.10 implementation agreement. In addition to NNI, Trillium's Q.933 software product supports Frame Relay UNI implementation agreements Q.933 (Case A and Case B), X.36 and FRF.4, Frame Relay PVC management procedure implementation agreements Q.933 Annex A, and American National Standards Institute See ANSI. (body, standard) American National Standards Institute - (ANSI) The private, non-profit organisation (501(c)3) responsible for approving US standards in many areas, including computers and communications. ANSI is a member of ISO. (ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. ) Annex D. For more detailed technical information, Trillium has written a Frame Relay white paper located at http://www.trillium.com/resource.html .
