摘要： Disclosed is an apparatus for and method of routing telephony data packets by checking the address of each data packet as the data packet is sent to a common random access memory to be used by all of a plurality of router. The appropriate output link is ascertained by use of a lookup table accessible by each of the plurality of routers. The location of the data packet in memory is then sent to a FIFO entity associated with the appropriate output link. When the queue for that link reaches a pointer in the FIFO for that data packet, it is retrieved from memory and forwarded to its destination. The design of the overall router entity facilitates monitoring of average input traffic as well as output traffic on each link at a data packet or byte level, monitoring the traffic of any input link by copying all data packets received from a given link to a monitoring link, restricting the capability of link sources from broadcasting data packets, checking individual or composite FIFO queue levels to determine the amount of time a link or links are operating at full capacity.
摘要翻译：公开了一种用于通过检查每个数据分组的地址来路由电话数据分组的装置和方法，因为数据分组被发送到要由多个路由器全部使用的公共随机存取存储器。通过使用由多个路由器中的每一个可访问的查找表来确定适当的输出链路。然后将数据分组在存储器中的位置发送到与适当的输出链路相关联的FIFO实体。当该链路的队列到达该数据分组的FIFO中的指针时，它从存储器检索并转发到其目的地。总体路由器实体的设计便于监视每个链路上的平均输入流量以及输出流量数据包或字节级，通过将从给定链路接收的所有数据包复制到监视链路来监视任何输入链路的流量，限制链路源从广播数据包的能力，检查单个或复合FIFO队列级别以确定链接或链接以全容量运行的时间量。

摘要： A reconfigurable RF transceiver for use in either a base station or a mobile station Of a wireless network. The reconfigurable RF transceiver comprises a first receive path that down-converts an incoming RF signal to analog and digital baseband signals. The first receive path in a first mode down-converts the incoming RF signal in a receive frequency band for the base station and in a second mode down-converts the incoming RF signal in a receive frequency band for the mobile station. The reconfigurable RF transceiver further comprises a transmit path for up-converting an outgoing baseband signal to an outgoing RF signal. The transmit path in the first mode up-converts the outgoing baseband signal in a transmit frequency band for the base station and in the second mode up-converts the outgoing baseband signal in a transmit frequency band for the mobile station.

摘要： A multi-mode mobile station comprising 1) reconfigurable transceiver circuitry for communicating with wireless networks operating under different air interface standards; 2) a memory for storing at least a download configuration file and a home configuration file; and 3) a main controller for configuring the reconfigurable transceiver circuitry to operate according to a home network wireless standard using home configuration data retrieved from the home configuration file. If the main controller determines that a network operating according to the home network wireless standard cannot be found, the main controller is further capable of configuring the reconfigurable transceiver circuitry to operate according to a download channel wireless standard using download configuration data retrieved from the download configuration file. The main controller then establishes a download channel with a local roaming wireless network and downloads a roaming network configuration file from the roaming wireless network over the download channel.
