Abstract: A communication multiplexer device is provided. The multiplexer device includes a legacy port adapted to communicate a legacy data frame format having at least one major data frame. The legacy major data frame includes overhead fields which may include a sync field. The legacy major data frame also includes three minor frame groups, where each of the minor frame group includes minor frames having subframe formats. The multiplexer also includes a contemporary port adapted to communicate a contemporary data frame format; and a translator coupled between the legacy port and the contemporary port for translation between the legacy data frame format and contemporary data fame format.

Abstract: The invention provides a children's playground device to be used for climbing up and sliding down. The device is configured in the form of a pyramid, having a multi-sided base and planar surfaces extending upwardly and inwardly to a top pad at the center. Alternate planar surfaces are adapted for climbing with padded, irregular surface treatments, and intermediate planar surfaces are adapted for sliding down with low friction smooth surface treatments. A resilient pad is supplied around the base to cushion the downward impact of users of the device. A further embodiment is configured as a semi-pyramid and is adapted to be placed against a wall or partition.
