    Abstract: The test system of the invention uses suppressed ringing connections from a test unit to the customer premise equipment via the central office to establish connections for performing the loop-back test. The suppressed ringing connections are established over standard voice trunks between a switch in the central office and the test unit by a central office service unit (COSU) such that the number of lines that can be tested simultaneously is limited only by the number of trunks linking the COSU to a switch. Because these trunks are relatively inexpensive and simple to install and maintain, the test system of the invention can be readily installed and expanded in the existing network to provide virtually any level of monitoring capability.

    Abstract: The invention uses a suppressed ringing connection, switched through the existing call processing switch fabric, to connect between two customer premise equipments (CPEs) for long duration, low priority calls. The suppressed ringing connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoing request for service from one of the CPEs is made. If the suppressed ringing connection is disconnected due to a request for normal service to or from one of the CPEs, the system of the invention automatically reestablishes the suppressed ringing connection after the normal service call has ended such that the long duration suppressed ringing connection can be maintained on a quasi-permanent basis. As a result, the suppressed ringing connection can be maintained for long duration connections without disrupting normal incoming or outgoing service to either of the connected CPEs.

    Abstract translation: 本发明使用通过现有呼叫处理交换结构切换的抑制振铃连接，连接长时间，低优先级呼叫的两个客户端设备（CPE）。 被抑制的振铃连接被实现为使得如果对其中一个CPE进行呼入呼叫或者从其中一个CPE发出去话请求服务，则断开该连接。 如果抑制振铃连接由于向或从其中一个CPE的正常业务的请求而断开，则本发明的系统在正常业务呼叫结束后自动重新建立抑制振铃连接，使得长时间抑制振铃连接可以是 保持在一个准永久的基础上。 结果，可以保持抑制的振铃连接长时间连接，而不会中断对任一连接的CPE的正常传入或传出服务。
