A system for housing CompactPCI cards in a frame that does not meet a specified CompactPCI form factor (3U and 6U) is presented. Existing telecommunication frames have generally a larger depth that those required by the CompactPCI standard (160 mm) and therefore the insertion of CompactPCI cards (201) cannot be performed directly into the main backplane (204) of the frames. An intermediate backplane (200), or so-called CompactPCI backplane, comprising six CompactPCI connectors on a front side for allowing the insertion of up to six CompactPCI adapters (201) (3U and/or 6U), and one doubled-headed CompactPCI connector (203) on a back side being common to one of the six front side connectors (203/206) for insertion of a System Card (202), is connected to the main frame backplane (204) using the System Card (202). The System Card functions as a card extender between the CompactPCI adapters (201) and the main backplane of the frame. The depth of the System Card (209) will be such that the depth of CompactPCI cards (208) plus the depth of the System Card (209) spans the full depth of the frame (207).
