Specifically designed for network managers and technicians. Toning an active LAN circuit can disrupt network traffic and is difficult to track due to cable twist and tone bleed. This test system works with both active and inactive (dark) cables, and features a port ID function that blinks the link light to verify cable connectivity.

This feature also provides a simple and effective method to identify a connected hub or switch port assignment on active networks.

This kit also detects shorts by using a built-in continuity check.

Three different blink rates are provided to ensure compatibility with equipment from a wide range of manufacturers. Traditional toning (a total of four audible tones) with two different tone frequencies and patterns is provided for non-active circuit tracing.

The CT10 toner/blinker has a female RJ45 connector for easy network connection to connect with the included RJ45 patch cord. It has a unique capability of user-selectable blink rates for compatibility with the widest range of LAN equipment. Detachable alligator clips can connect to punchdown blocks or unterminated cables. Auto power down extends battery life, and a built-in low battery indicator warns when battery replacement is required.
