Adax Announces New Fully Redundant Signaling Gateway Pair for High Availability; Distributed Design and Operation with No Single Point Of Failure.BOSTON -- Adax has announced a significant new High Availability addition to its family of signaling gateway products. The Adax SG-HA has a fully redundant design with no single point of failure to provide a highly reliable SS7 -- IP gateway solution. Designed to be implemented as a mated pair with a single point code the SG-HA performs like a traditional SS7 STP STP or standard temperature and pressure, standard conditions for measurement of the properties of matter. The standard temperature is the freezing point of pure water, 0°C; or 273.15°K;. , relaying traffic rather than being an endpoint, while providing IP inter-working with SIGTRAN (SIGnaling TRANsport) An IP telephony protocol from the IETF that is used to transfer SS7 signals over IP networks. The telco switch sends SS7 signals to a signaling gateway (SG) that converts them into SIGTRAN packets, which travel over IP to the next signaling gateway or endpoints and SoftSwitches. In addition to M3UA M3UA MTP (Message Transfer Part) Level 3 User Adaptation Layer (IETF) M3UA Mtp3 User Adaptation (MTP3 User Adaptation Part) both the Signaling Connection Control Part (SCCP (Signaling Connection Control Point) A layer 3 protocol in an SS7 network that routes a message to the appropriate database. SCCP is used in conjunction with the TCAP protocol for sending queries to databases. See SS7 and TCAP. See also SSCP. ) and the SUA (SCCP User Adaptation Layer) protocols have been added to the Adax SG-HA Gateway. SS7 SCCP provides connectionless network services above MTP3 and is used as the transport layer for TCAP-based services such as freephone, calling card, local number portability "LNP" redirects here. For the airport in Virginia with that IATA code, see Lonesome Pine Airport. For the compound InP, see Indium phosphide. Local number portability, (LNP) for fixed lines, and full mobile number portability , wireless roaming, and personal communications services See PCS. (PCS). SCCP also provides the means by which an Adax SG can perform global title translation (GTT GTT, n See test, glucose tolerance. GTT Glucose tolerance test, see there ) to enable the destination signaling point and subsystem number (SSN) to be determined from the signaling message. SUA is a SIGTRAN protocol for transporting SCCP user part signaling messages (e.g. TCAP (Transaction Capabilities Application Part) The protocol used in an SS7 network for sending database queries to a service control point (SCP). The SCP provides the interface to local and remote databases that contain subscriber and routing information. ) over IP using SCTP (1) (Stream Control Transmission Protocol) An alternative to TCP that supports multiple transmission paths. Designed to facilitate SS7 signaling over TCP/IP, SCTP supports multiple IP addresses from the same host (multihomed host) and treats the data . SUA is used between a signaling gateway and an IP signaling endpoint, or between IP signaling endpoints and supports unordered and in-sequence connectionless services, bi-directional connection-oriented services with or without flow control and detection of message loss and out-of-sequence errors. SUA operates with either connection-oriented or connectionless transport and is a signaling solution for companies who are running SCCP on SS7 devices that need to connect to IP devices. "With the announcement of the SG-HA we have now added STP functionality to our range of Signaling Gateways," said Barry Zuckerman, President of Adax Inc. "This fully redundant, distributed solution that appears to the network as a single point code is a must for our high-end telecom customers." The link density, throughput and performance of the Adax Signaling Gateways have all been increased following upgrades to the communications controllers and software modules. These improvements enable operators to manage the growth of their network while maximizing revenues and satisfying consumer demands for new services. The five Adax SS7 over IP gateways for switching, routing, tunneling and backhaul are capable of supporting up to 2 million BHCA (Busy Hour Call Attempts) The number of times a telephone call is attempted during the busiest hour of the day. See busy hour. (Busy Hour Call Attempts In telecommunications, Busy Hour Call Attempts (BHCA) is a teletraffic engineering measurement used to evaluate and plan capacity for telephone networks. BHCA is the number of telephone calls attempted at the busiest hour of the day (peak hour), and the higher the BHCA, the ) and are scalable up to 5 million BHCA and beyond. Each Adax Gateway system can support up to 64 SS7 LSLs or 4 HSLs (subject to configuration). In addition, the gateways are now capable of delivering 253 SCTP associations with up to 25 secondary IP addresses per association. The gateways are NEBS certified platforms for carrier-grade system reliability and the new Adax SG-HA has a fully redundant design with no single point of failure to provide a highly reliable SS7 -- IP gateway solution. With outstanding performance and reliability the Adax gateways offer one of lowest costs per link and highest throughputs available on the market today. The Adax signaling gateways enable the simple and straightforward migration of existing SS7 Nodes to IP transport, saving the costs associated with leasing or provisioning dedicated long haul SS7 circuits. In addition, the migration to IP signaling enables the network to deal with the increasing demands for bandwidth from new applications such as video gaming and with the more 'bursty' nature of traffic generated by SMS and multi-media messaging. The Adax gateways offer various types of SS7 over IP solutions to suit the different stages of migration to IP signaling. The gateways have a common field hardware platform and through a simple software upgrade can easily evolve with changing IP needs including M2PA M2PA MTP2-User Peer-to-Peer Adaptation Layer M2PA Mtp2 Peer to Peer Adaptation Layer , M2UA, M3UA and SUA. They are also readily scalable to grow in line with the demands of the network, future-proofing a customer's equipment investment choice. About Adax Inc.
