Radcom [RDCM], an Israel-based manufacturer of support network services, announced the availability of a new testing system to monitor and to troubleshoot LAN, WAN, ATM and other communications capabilities. The testing system, called the Performer Analyzer, assesses network efficiency by using Global Positioning System (GPS) or Network Time Protocol (NTP) technology to provide accurate and time-dependent measurements among several units in a lab or across remote sites, company officials said.
