The SmartClass IW-1000 handheld service meter enables verification of internal wiring at the customer premises for proper operation of voice, video, and data services. The IW-1000 is used to test the coax and twisted pair wiring inside the home, in multiple dwelling units (MDUs), and in small-to-medium-sized businesses (SMBs), providing an easy-to-use, accurate, and economical measurement tool for service technicians installing or troubleshooting triple-play services over existing or new networks. The IW-1000 includes a unique set of features to completely qualify the physical media used to deliver triple-play services throughout the site. The Coax Map feature and the Noise Immunity Test can be used to assess quality and troubleshooting issues in a coax network. The Active ID can delineate multiple runs of coax in the building even through coaxial splitters. The integrated wiring tools can also be used to qualify twisted pair, including Cat3, Cat5, Cat5e, and Cat6 cables. The IW-1000 saves time and effort in verifying and troubleshooting inside wiring problems before the subscriber notices them. The IW-1000 also includes a unique feature set for testing Ethernet data networks in residential and SMB locations. An optional 802.11b/g wireless feature can be added to ensure correct WiFi functionality in and around the subscriber locations.
