<p>A keying system for assuring the proper sequence or arrangement of cable cards (10) within a card grouper (12) is provided. The grouper includes a plurality of slots (26, 28) to receive the cable cards. The cards include tab means (33, 34, 36, 37) at at least one side thereof which can be selectively trimmed to one of several specific extension distances from the card. The grouper includes a template which has grooves configured to receive cards having their tabs programmed to one and only one configuration. Thus any given card, when programmed, will fit in only one location. The cards and grouper also include coacting surfaces (32) to allow the appropriate card to be inserted in only one orientation in any given slot.</p> |
