    • A system and method to provide a busy signal to a communication without a terminating network element providing answer supervision and without the originating caller associated with the communication being charged for the communication. A communication that has been forwarded over an integrated services digital network (ISDN) interface connection from a central office to a terminating network element for further routing of the communication to a terminating unit is accepted at the terminating network element and an ISDN interface connection is made, but answer supervision with respect to the communication is not provided. Upon a determination that the terminating unit to which the communication would otherwise be forwarded is busy, the terminating network element provides an ISDN release complete message with respect to the communication to the central office. The ISDN release complete message instructs the central office to play a busy signal to the communication. The terminating network element also releases the ISDN interface connection to the communication. In response to receipt of the ISDN release complete message from the terminating network element, the central office plays a busy signal to the communication.
    • 一种系统和方法,用于向通信提供忙信号,而无需终端网络单元提供应答监督,并且不需要与通信相关联的始发呼叫者被收费进行通信。 已经通过综合业务数字网络(ISDN)接口连接从中心局转发到终端网络元件以进一步将通信路由到终端单元的通信在终端网络元件处被接受并且进行ISDN接口连接 ,但没有提供关于通信的回答监督。 一旦确定通信将以其他方式被转发到的终端单元繁忙,则终端网络元件提供关于到中心局的通信的ISDN释放完成消息。 ISDN释放完成消息指示中心局向通信发送忙信号。 终端网络元件也释放到通信的ISDN接口连接。 响应于从终端网络元件接收到ISDN释放完成消息,中心局向通信发送忙碌信号。

    • The invention relates to a procedure for the processing of an unexpected disconnect request in an access node (AN) which is connected to a local exchange (LE) over a V5 interface. In the access node (AN), call setdown is effected by means of a disconnect message, which is sent from the local exchange (LE) and on the basis of which the call resources in the local exchange (LE) are released. According to the invention, the resources reserved in the access node (AN) for the call are preserved. Moreover, the local exchange (LE) is informed that the subscriber is busy, thus preventing the occurrence of an undefined condition between the local exchange (LE) and the access node (AN).
    • 本发明涉及在接入节点(AN)中处理意外断开请求的过程,该接入节点通过V5接口连接到本地交换机(LE)。 在接入节点(AN)中,通过从本地交换机(LE)发送的断开消息并且释放本地交换机(LE)中的呼叫资源的基础上,进行呼叫限制。 根据本发明,保留用于该呼叫的接入节点(AN)中保留的资源。 此外,本地交换机(LE)被通知用户忙,从而防止本地交换机(LE)和接入节点(AN)之间出现未定义的状况。
