The SuperLooper™ T1/E1 Loopback Jack and Plug quickly and easily checks the RX/TX pairs of T1/E1 circuit cables helping a network technician determine if a signal exists or if there are broken or shorted wires within the cabling. It can be plugged directly into a T1/E1 CSU/DSU or can be attached to the end of a network patch cable. If a signal is present, the SuperLooper™ T1/E1 Loopback Jack and Plug sends the signal back to the source illuminating the port light on the associated T1/E1 equipment.

Molded hybrid casing providing both male and female jacks. Small, convenient, and economical for network technicians. Easy access with key chain attachment. Color coded for quick recognition.
