    • A method of supporting multiple quality of service (QoS) levels for data being transmitted between two networking devices, such as customer equipment (CE), that use Ethernet and Frame Relay (FR). The method supports multiple QoS services in a network where a first CE is connected to a first edge device (interworking unit) using the Ethernet protocol and a second CE is connected to a second edge device using the FR protocol. The edge devices may be directly connected together or they may be connected through a network backbone using any generally accepted network protocol. The first CE may be connected to the first edge device using a single Ethernet port, multiple Ethernet ports, a single virtual local area network (VLAN), or multiple VLAN's. The second CE is connected to an edge device using a single data link connection (DLC), or multiple DLC's. The method ensures QoS for data transmitted between the first and the second CE via the Ethernet protocol to the FR protocol and vice versa.
    • 支持使用以太网和帧中继(FR)的两个网络设备(例如客户设备(CE))之间传输的数据的多个服务质量(QoS)级别的方法。 该方法支持使用以太网协议将第一CE连接到第一边缘设备(互通单元)的网络中的多个QoS服务,并且使用FR协议将第二CE连接到第二边缘设备。 边缘设备可以直接连接在一起,或者它们可以使用任何普遍接受的网络协议通过网络主干连接。 第一个CE可以使用单个以太网端口,多个以太网端口,单个虚拟局域网(VLAN)或多个VLAN连接到第一个边缘设备。 第二个CE使用单个数据链路连接(DLC)或多个DLC连接到边缘设备。 该方法通过以太网协议向FR协议确保在第一和第二CE之间传输的数据的QoS,反之亦然。

    • A method of supporting multiple quality of service (QoS) levels for data being transmitted between two networking devices, such as customer equipment (CE), that use Ethernet and Asynchronous Transfer Mode (ATM). The method supports multiple QoS services in a network where a first CE is connected to a first edge device (interworking unit) using the Ethernet protocol and a second CE is connected to a second edge device using the ATM protocol. The edge devices may be directly connected together or they may be connected through a network backbone using any generally accepted network protocol. The first CE may be connected to the first edge device using a single Ethernet port, multiple Ethernet ports, a single virtual local area network (VLAN), or multiple VLAN's. The second CE is connected to an edge device using a single virtual circuit connection (VCC), a single virtual path connection (VPC), or multiple VCC's. The method ensures QoS for data transmitted between the first and the second CE via the Ethernet protocol to the ATM protocol and vice versa.
    • 支持在使用以太网和异步传输模式(ATM)的两个网络设备(例如客户设备(CE))之间传输的数据的多个服务质量(QoS)级别的方法。 该方法支持网络中的多个QoS服务,其中第一CE使用以太网协议连接到第一边缘设备(互通单元),第二CE使用ATM协议连接到第二边缘设备。 边缘设备可以直接连接在一起,或者它们可以使用任何普遍接受的网络协议通过网络主干连接。 第一个CE可以使用单个以太网端口,多个以太网端口,单个虚拟局域网(VLAN)或多个VLAN连接到第一个边缘设备。 第二个CE使用单个虚拟电路连接(VCC),单个虚拟路径连接(VPC)或多个VCC连接到边缘设备。 该方法通过以太网协议向ATM协议确保在第一和第二CE之间传输的数据的QoS,反之亦然。

    • A continuous, non-metallic conduit for conductors, such as electrical wiring and/or fiber optic cable. The continuous conduit being formed from at least one pair of first and second conduits having enlarged ends coupled together. The enlarged ends are belled or otherwise have a diameter greater than that of the straight run (non-belled) portions of the conduit. The enlarged ends of the conduit being coupled together by fusion or welding, and an internal bead or ridge being formed by the coupling process. The enlarged ends are dimensioned such that the internal bead or ridge formed at the junction between the two enlarged ends does not project radially inward to a position equal to or less than the diameter of the straight run portion of the conduits. The continuous conduit is configured to allow the conductor to be passed therethrough such that the conductor does not contact the internal bead or ridge.
    • 用于导体的连续的非金属导管,例如电线和/或光纤电缆。 连续管道由至少一对第一和第二管道形成,第一和第二管道具有扩大的端部联接在一起。 扩大的端部被鼓起或者具有比导管的直线(非鼓形)部分的直径大的直径。 通过熔接或焊接将导管的扩大端连接在一起,以及通过耦合过程形成的内部珠或脊。 扩大的端部的尺寸使得形成在两个扩大端部之间的接合部处的内部胎圈或脊部不径向向内突出到等于或小于导管的直线部分的直径的位置。 连续管道被配置为允许导体通过,使得导体不接触内部珠缘或脊。
