    • A wireless-access communications system, such as a CDMA cellular radio-telephone system (FIG. 2), comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). Traffic of individual calls is packetized, and packet-bearing frames (300 in FIG. 7) of a plurality of calls are then statistically multiplexed and frame-relayed through the network to yield the high capacity, efficiency, and speed of traffic transport and handoff required for a CDMA cellular system. At each call processing unit (264 in FIG. 5), individual calls are handled by individual service circuits (602 & 612) which perform speech-processing functions such as coding and decoding, tone insertion, and echo cancellation, and packet-to-circuit-switched-PCM traffic conversion. Processors (602) adapt call processing unit timing to compensate for asynchrony between cells and call processing units and variations in call path transmission delays. Cell-to-cell communications, fixed call path addressing, and packetized control message transfers ensure that the same service circuit handles a call through even multiple soft handoffs (FIGS. 27-29) and efficiently communicates simultaneously with all cells involved in the handoff without involvement of system control entities and negative effect on system call-handling capacity. Both coded (packet-switched) and uncoded (circuit-switched) radio-telephone traffic are accommodated side-by-side. Wherever possible, existing and proven technology and component units are used to achieve low cost and high reliability.

    • A panel assembly for the in-situ production of a standing seam roof has panels which, at one end, have a vertically standing hook formed atop a semi-trapezoidal fold, while at an opposite end, a vertically standing hook is formed atop and is part of a substantially trapezoidal fold. The first hook is designed to be simply and securely retained within the second hook through the use of a camming interlocking action and the free edge of the second end is upwardly bent so as to rest against the semi-trapezoidal fold of a like panel joined to said end to form a series of interconnected panels that are mounted to roof purlins by fasteners hidden by the standing seam. In a roof requiring plural parallel series of panels, upper and lower clamping bars are provided to form a tight, leak-proof lap joint between the adjacent panel series in a manner avoiding the need for the use of exposed fasteners which must extend through exposed roof portions.

    • Disclosed is a way of enhancing capabilities of an interface, such as a communications bus (100), while retaining backwards compatibility of the interface. The bus has a plurality of signal lines (250) including critical control signal lines. Legacy devices (102-103) present a legacy interface to each other over the bus by communicating with each other via a legacy protocol (251) over the bus. Critical control signals of the legacy protocol are conveyed by the critical control signal lines. New devices (104-105) present an enhanced interface to each other over the same bus by communicating with each other via an enhanced protocol (252) over the bus. Control signals of the enhanced protocol are conveyed by signal lines other than the critical control signal lines for the legacy protocol, so that the critical control signal lines remain idle or invalid for the legacy protocol. The new devices signal to each other an intent to use the enhanced protocol by sending a signal on a signal line (253) that is not used by the legacy protocol. The new devices preferably can communicate on the bus via either protocol, and thus can communicate not only with each other but also with the legacy devices.
    • 公开了一种提高诸如通信总线(100)的接口的能力的方式,同时保持接口的向后兼容性。 总线具有包括关键控制信号线的多条信号线(250)。 传统设备(102-103)通过总线通过传统协议(251)通过总线彼此通信来呈现通过总线彼此的传统接口。 传统协议的关键控制信号由关键控制信号线传送。 新设备(104-105)通过总线上经由增强协议(252)彼此通信来在同一总线上呈现彼此的增强接口。 增强协议的控制信号由传统协议的关键控制信号线以外的信号线传送,使得关键控制信号线对于传统协议保持空闲或无效。 新设备通过在传统协议不使用的信号线(253)上发送信号来彼此发信号通知使用增强协议。 新设备优选地可以经由任一协议在总线上进行通信,并且因此可以不仅彼此通信,而且可以与传统设备进行通信。
