A test cable is spooled on a spring loaded cable reel that is structurally connected to a buttset via an anchor that holds on to a cable outlet of the buttset housing. A releasable ratchet holds the spool against a reeling spring such that the pulled out test cable may be conveniently handled without cable tension. To retract the test cable, the ratchet may be released by a small pull on the test cable. A number of such cable reels may be stacked inside a compact housing. Existing buttsets may be easily retrofitted by merely replacing its strain relief and dangling test cable. As a favorable result, test cable damage due to its wrapping around the buttset is avoided while test cable handling is optimized.
