摘要： A method (10, 20) and apparatus (30) enables a customer (47) to distinguish between a dead or broken Internet Protocol telephone line and an out-of-service Internet Protocol telephone line. The method detects (11) a hook status of a device (46) coupled to the IP network (33) during an out-of-service status of the line. Upon detection of a change in state from an on-hook state to an off-hook state, a message is sent (13) to the device (46) indicating that the IP telephone line is currently out-of-service and not dead or broken. This message can be a voice or text message. Moreover, the message can provide status information for all of the interfaces of the device coupled to the IP telephone line. In addition, the message can include information as to how to obtain service, such as a telephone number to call.

摘要： A method and apparatus is provided for use in providing real-time, packet-switched service to an end-user over a cable data network. The method begins by transmitting over the cable data network a scheduled grant to an end-user gateway in accordance with an unsolicited grant service protocol. The grant authorizes the end-user gateway to transmit a data packet to a cable modem termination system (CMTS) located in the cable data network. Next, an adjustment is made to the time at which subsequent grants are transmitted. The adjustment, which is based on a response of the end-user gateway, is performed to reduce delay between a time when a subsequent data packet is generated and receipt of the subsequent grant.
摘要翻译：提供了一种用于通过有线数据网络向最终用户提供实时分组交换服务的方法和装置。该方法开始于根据非请求授权服务协议通过有线数据网络将调度授权发送到终端用户网关。该授权授权最终用户网关将数据分组传送到位于电缆数据网络中的电缆调制解调器终端系统（CMTS）。接下来，对发送后续授权的时间进行调整。执行基于最终用户网关的响应的调整，以减少在产生后续数据分组的时间和后续授权的接收之间的延迟。
