DSL Test unit with 1 ft. test cord - The Suttle DSL Test Unit allows for an active DSL line to be tested for POTS (voice) verification without interfering with the DSL service connection The hand-held device has an RJ-14 modular jack for the input connection. The input can be made with a double-ended modular cord or with a universal test cord equipped with a modular plug on one-end and test clips on the other as used with a typical Butt set. The connection for the testing is provided via two RJ-14 modular jacks labeled "Non-Filtered" for the DSL port and "Filtered" for the POTS port, or through the test access point terminals for use with a test cord.
