    • A method manages a communications link in which a first device (110) interfaces with a first channel extender (310) and in which a second device (120) interfaces with a second channel extender (320), and in which the first and second channel extenders (310, 320) communicate with each other through a communications medium (330). The method involves (FIG. 7A) monitoring an occupancy (“b”) of a receive buffer (922+924) in the first channel extender (310) during transmission from the second channel extender (320) at a first transmission rate (R0); (FIG. 7B) at a first time (Tlwm) when the occupancy of the receive buffer (922+924) exceeds a first threshold (B0+Bcr), immediately instructing (718) the second channel extender (320) to cease transmission to the first channel extender (310); (FIG. 7C, 732) monitoring for an overflow condition in the receive buffer (922+924); if (FIG. 7D, 758) the overflow condition is present, specifying (760) that a future transmission to the first channel extender (310) be at a second transmission rate (R′0) that is lower than the first transmission rate (R0); and instructing (FIG. 7D, 762) the second channel extender (320) to resume transmission to the first channel extender (310).
    • 一种方法管理通信链路,其中第一设备(110)与第一信道扩展器(310)接口,并且其中第二设备(120)与第二信道扩展器(320)接口,并且其中第一和第二信道 扩展器(310,320)通过通信介质(330)彼此通信。 该方法涉及(图7A)在以第一传输速率(R0)从第二信道扩展器(320)传输期间监视在第一信道扩展器(310)中的接收缓冲器(922 + 924)的占用(“b” ); (922 + 924)的占有率超过第一阈值(B0 + Bcr)时,在第一时间(Tlwm)(图7B),立即指示(718)第二信道扩展器(320)停止向 第一通道延长器(310); (图7C,732)监视接收缓冲器(922 + 924)中的溢出状态; 如果(图7D,758)存在溢出条件,则指定(760)到第一信道扩展器(310)的未来传输处于低于第一传输速率的第二传输速率(R'0) R0); 并且指示(图7D,762)第二信道扩展器(320)恢复发送到第一信道扩展器(310)。

    • An arrangement for routing toll calls to a predominant local exchange carrier (LEC) or to a competitive access provider (CAP). An egress switch of an interexchange (toll) carrier translates the called directory number office code to determine whether that code serves a CAP. If so, an exception table is searched to identify the CAP. If the called number is not in the exception table, the call is routed to the predominant LEC. Calls may also be routed to a customer who is served by a CAP and the predominant LEC via either of these local carriers. The billing record identifies an originating and/or a terminating CAP for the call. Optionally or alternatively, an ingress IXC switch may access a data base to determine the CAP or predominant LEC serving a called customer. The ingress IXC switch then routes the call to an IXC egress switch serving the carrier that serves the called customer. Advantageously, this arrangement efficiently serves calls using a CAP to provide part of the connection.
    • 用于将路费长途电话路由到主要的本地交换运营商(LEC)或竞争性接入提供商(CAP)的布置。 交换(收费)运营商的出口交换机转换被叫目录号码办公室代码,以确定该代码是否服务于CAP。 如果是,则搜索异常表以识别CAP。 如果被叫号码不在异常表中,则呼叫路由到主要的LEC。 呼叫也可以路由到由CAP和主要的LEC通过这些本地运营商服务的客户。 记帐记录标识呼叫的发起和/或终止CAP。 可选地或替代地,入口IXC交换机可以访问数据库以确定为被叫客户服务的CAP或主要LEC。 入口IXC交换机然后将呼叫路由到服务于被叫客户的运营商的IXC出口交换机。 有利地,这种安排有效地使用CAP提供呼叫以提供部分连接。
