摘要： In an Intelligent Network (IN) (10) a testing capability is provided at a service switching point (SSP) (12). The testing capability comprises a test call (34) initiated from the SSP to a desired destination (14) within the network. The testing capability uses the Common Channel Signaling Number 7 (CCS7) network protocol. It uses the CCS7 TCAP (Transaction Capability Control Park) for IN queries packages (50) and the CCS7 ISDN User Part (ISUP) (40) for call set up messages. The testing capability defines a portion on the (TCAP) and (ISUP) to log (TLog) the network devices transversed in the IN call. The test call with the log portion appended to TCAP (and ISUP) messages travels through the network and collects data (208, 210) in the log portion from each node on the test call path. The test call with the travelling log (TLog) helps the maintenance personnel isolate troubles and faults in the network without having to monitor each node (or office) on the route of a troubled message path.

摘要： A layered architecture for a communication network comprises a first layer forming a transport network and a second layer forming a service network. The transport network provides bandwidth management, high capacity and physical layer survivability, and the service network provides switching and routing of the traffic, service layer survivability and other user oriented services. Combination of various technologies such as ATM, or IP over SONET/SDH are considered. A node of such layered networks comprises physically separated transport and service network elements (NE) interfaced to each-other.

摘要： The invention manifests a secure, on-demand meet-me conferencing service embodied within a telephone network having an advanced intelligent network (AIN) infrastructure. Centralized control from a service control point of provisioned conferencing bridges located in network switches is effected in the AIN telephone network, thereby overcoming the resource efficiency limitations and corresponding costs of the prior art systems. In addition, it enables the local exchange carrier (LEC) to offer of a new type of conferencing service at a lower cost where prior reservation of conferencing facilities is no longer necessary and which possesses other advantages with respect to ease of use, ease of administration, availability and security. Users of the service first subscribe to it, and then utilize paired primary and secondary authorization codes to access a conference.

摘要： A telephone line interface circuit with d.c. amplifiers (12) coupled to tip and ring paths is protected against transient voltages by a crowbar-type protection device (52) coupled via a diode bridge (28, 30) to the tip and ring paths, positive and negative terminals of the diode bridge being connected respectively to ground and via a diode (54) to a negative supply voltage line for the amplifiers. The diode prevents discharge of a capacitor (26), coupled between the negative supply voltage line and ground, through the protection device when it conducts. A locked up state, in which the amplifiers maintain holding current to the protection device after a transient voltage, is avoided by further diodes (56, 58) coupled from the negative terminal of the diode bridge to inputs of the amplifiers, or by controlling a current limiter (34) to interrupt current to the capacitor when the diode is reverse biased, so that the capacitor discharges. The current limiter includes a resistance (38) and inductance (40) in series for sensing current, whereby initial charging current for the capacitor is reduced on closing of relay contacts (K1, K2) in series with the current limiter, and relay contact deterioration is avoided.

摘要： For restoration of a network a plurality of possible alternative routes are determined. Messages are passed between nodes along the alternative routes to determine a spare capacity of each link in the alternative routes. An alternative route is selected from the possible alternative routes on the basis of a database of the determined link spare capacities for each of the possible alternative routes, built up at a chooser node at one side of the failed part of the network.

摘要： A technique for updating a routing table in a routing device operating over a logical connection in a communication network utilizes a mechanism at a first protocol layer to determine a logical connection status and trigger a routing table update at a second protocol layer based upon the logical connection status. Specifically, the first protocol layer logic monitors the status of the logical channels, and, based on the status of the logical channels, determines the status of the logical connections. When the first protocol layer logic detects a logical channel failure that results in a logical connection failure, the first protocol layer logic triggers a routing table update by sending a signal to the second protocol layer logic indicating that the logical connection failed. Likewise, when the first protocol layer logic determines that communication over the failed logical connection is restored, the first protocol layer logic triggers a routing table update by sending a signal to the second protocol layer logic indicating that the logical connection is restored.
摘要翻译：用于在通信网络中通过逻辑连接操作的路由设备中更新路由表的技术利用第一协议层的机制来确定逻辑连接状态，并且基于逻辑连接在第二协议层触发路由表更新状态。具体地，第一协议层逻辑监视逻辑信道的状态，并且基于逻辑信道的状态来确定逻辑连接的状态。当第一协议层逻辑检测到导致逻辑连接失败的逻辑信道故障时，第一协议层逻辑通过向第二协议层逻辑发送指示逻辑连接失败的信号来触发路由表更新。同样，当第一协议层逻辑确定通过故障逻辑连接的通信被恢复时，第一协议层逻辑通过向第二协议层逻辑发送指示逻辑连接被恢复的信号来触发路由表更新。

摘要： The present invention relates to telecommunication systems that facilitate distributed access to voice and data communications (in particular PBX/Centrex and POTS services). A gateway (86) is connected to a PBX or Centrex switch (84) which puts speech and call control signals originating from the PBX or Centrex switch into Asynchronous Transfer Mode (ATM) cells and sends them to an ATM network (64). The ATM network transports the cells to a Digital Subscriber Loop Access Multiplexer (DSLAM)(66). The DSLAM provides an interface between the ATM network and a Digital Subscriber Loop (DSL) channel (68) connected to the customer premises (73). A Customer Premises Equipment (CPE)(70) reconstitutes the speech and call control signals and sends them to a telephone set (80) and/or computer device (82) attached thereto. Since the speech samples and call control signals originate with the customer's PBX or Centrex switch, the telecommuter and/or small branch office can use the same telephone set, same dial plan, same call features and same low-cost long-distance calling plan as colleagues back at the head office.
