Telecom industry gathers in Chicago
NXTcomm, McCormick Place, Chicago, IL, June 18–21.
-- Test & Measurement World, 6/21/2007 6:24:00 AM
NXTcomm (formerly GlobalComm, formerly SuperComm) opened on June 18 in the Windy City. NXTcomm draws numerous test-equipment makers, many of whom introduced new products or exhibited products they introduced earlier in the month.
Agilent Technologies used NXTcomm to introduce two telecom test products. The company announced the N2X N5575A/N5576A enhancement to its popular N2X Multiservice Test Platform. The new option emulates transmission control protocol (TCP) in hardware, which increases the speed at which it can generate and analyze TCP traffic. The N2X implements its TCP protocol stack using in FPGA rather than software. The N2X, which consists of a chassis and line cards, can test protocol layers 2 through 7.
Agilent also introduced the N4192A Network Tester, which lets you test networks at layers 4 through 7. The tester supports over 21 protocols including IPv6. It generates and analyzes voice, video, and data traffic. The N4192A can simulate network attacks, which lets you test firewalls and other network-security components.
Ixia added Provider Backbone Bridging (PBB) and Provider Backbone Transport support to its IxNetwork test software, which runs on the company’s Aptixia network testers. Release 5.30 also adds Ethernet operations and maintenance (OAM) and Configuration Fault Management (CFM), which comply with IEEE 802.1a/g.
See explanations of PBB and PBT from Nortel networks.

JDSU demonstrated its 2.5/2.7G jitter/wander module for the T-BERD/MTS-8000. This module upgrades the T-BERD/MTS-8000 mainframe to provide jitter measurements in the field on SONET/SDH networks. The company also announced enhancements to its HST-3000 handheld DSL tester. The enhancements include ADSL2+, VDSL, and IPTV in addition to its ability to test previous generations of ADSL and VoIP.
Pixelmetrix exhibited its DVStation-IP³ an enhanced and upgraded version of the DVStation-IP IP video monitoring systems. DVStation-IP³ can monitor and evaluate video quality in cable, satellite, and terrestrial video streams.
Polatis introduced its wavelength selective switch (WSS), an ultra low-loss switching technology for DWDM networks. The WSS can attenuate or block any wavelength and it can pass or drop any wavelength with 3 dB of optical insertion loss. You can configure the WSS for 1x9, 1x4, and 1x20 fiber drops. The company demonstrated the WSS in a 1x9 configuration.
Spirent Communications demonstrated its recently released Spirent TestCenter 2.0, a modular system for testing voice, data, and video networks. It consists of a chassis with network-interface cards that generates and analyzes traffic access networks, core networks, switches, routers, and DSLAMS at protocol layers 2 through 7. TestCenter 2.0’s software architecture has features that include automation, which provides a GUI-to-script tool that lets you set up tests with a GUI and convert them to TCl scripts. TestCenter 2.0 also includes prewritten test scripts for popular protocols such as Ethernet, Internet Protocol (IP), and Multiprotocol Label Switching (MPLS).
Today, Spirent announced 10GBASE-T interface for TestCenter, making the tester compliant with IEEE 802.3an.
Symmetricom announced the Q-400 monitoring probe that provides end-to-end network performance monitoring. It provides quality of service (QoS) and quality of experience (QoE) measurements using the company’s V-Factor scale. The Q-400 can monitor up to 400 standard-definition (SD) or high-definition (HD) IPTV streams that use H.264 protocols and up to 10,000 VoIP streams. It uses the Mean Opinion Score (MOS) for VoIP.
The company also announced and displayed its PackeTime server card, which provides network-time protocol (NTP) timing service-provider applications such as IPTV, Billing Record Management, QoS Measurement Systems, and IP Service Level Agreement (SLA) Monitoring.
Tektronix announced its Unified Assurance for Converged Networks (UACN), which provides end-to-end service level diagnostics on all user sessions across multiple access and core networks. The UACN currently focuses on voice service service-level monitoring and diagnostics.
