:TEK See TeX. ), Beaverton, Ore., a worldwide provider of communications network management and diagnostics, has launched new software for the market-leading Spectra(TM) diagnostics product that offers comprehensive Sigtran and SS7- based signalling conformance testing capabilities for telecommunications carriers, developers and equipment manufacturers. Spectra Release 5.2 adds the ability to emulate, test, generate and evaluate networks and network elements that support the SS7 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.  User Adaptation Layer (SUA) running over Steam Control Transmission Protocol (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 ).

As carriers build out next-generation networks, they need testing tools that help ensure interoperability between legacy and VoIP signalling technologies and validate equipment performance across converged networks. Spectra 5.2 software adds SUA Tester, a new application which works in conjunction with Spectra's 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.  Tester and TCAP Generator applications. Spectra 5.2 enables users to easily emulate network elements such as Application Servers (ASs), Application Server Processes (ASPs), Signaling Gateways (SGs), Signaling Processes (SPs) or Signal Transfer Points (STPs) that use SS7 and SUA over SCTP and IP network connections for signalling protocol delivery.

"Spectra 5.2 further increases Spectra's overall Sigtran testing portfolio by providing conformance testing for the new SUA technology," said Richard Kenedi, senior director, Diagnostics, Tektronix. "With the full suite of SUA testing features added to existing support for M2PA M2PA MTP2-User Peer-to-Peer Adaptation Layer
M2PA Mtp2 Peer to Peer Adaptation Layer
 and M3UA M3UA MTP (Message Transfer Part) Level 3 User Adaptation Layer (IETF)
M3UA Mtp3 User Adaptation
 protocol testing, Tektronix provides the most comprehensive suite of protocol monitoring, testing, generation and emulation support to verify the integrity and compliance of IP and PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S.  network protocols."

The SUA Tester application generates SS7 SCCP and TCAP signaling traffic to stress test ASPs and SGs. Users can perform functional and conformance testing for ASPs, SGs and AS(s), as well as evaluate SUA protocol performance across SGs, ASPs and AS(s).

The Spectra 5.2 Release is part of Tektronix' Internet Protocol Diagnostics (IPD) product portfolio that provides network equipment manufacturers and service providers easy-to-use test and measurement tools for the analysis and QoS measurement of media over IP and protocols in the core of converged multiservice networks.
