A feature checker provides the ability to review communications service features for interaction problems at service creation time, or at runtime. Hence a feature can be reviewed against existing service features or against a specific other user's features.The feature checker is based on modelling communications service features as constraint satisfaction problems in which constraints 600, 605 determine preset relationships between values 610, 615 for variables 200, 215, 300, 400 of the feature. The model can then be searched for inconsistencies which indicate feature interaction. Interaction can be solved by building in an "alternative invoke" 610 for a feature which overcomes the inconsistency. This might be for instance a form of invoke which, when instantiated, actively suppresses a conflicting feature.

An LED terminal monitoring circuit detects an LED at the lowest potential among a plurality of parallel-connected LEDs. An analog signal selecting circuit gives a signal indicating the voltage of the detected LED to a boosting circuit.

Signal lines not connected to LEDs are excluded from objects of a LED-switching control operation.

In a tunnel connecting a source node to a destination node, data transfer for the tunnel is enabled through a first path. The data transfer is enabled by reserving resources in intermediate nodes in the first path between the source node and the destination node. Data transfer for the tunnel may be switched from the first path to a second path by reserving resources in intermediate nodes in the second path. If an intermediate node in the second path is shared by the second path and the first path, the resources reserved by the first path are shared by the second path. If an intermediate node in the second path is not shared by the first path, resources are reserved by the second path. After resources are reserved in the second path and data transfer is enabled in the second path, data transfer for the tunnel is switched to the second path.

A packet-aware time division multiplexing (TDM) switch includes one or more ingress ports, one or more egress ports, a TDM switching fabric, and a bandwidth manager. Ingress ports are capable of distinguishing packets. The TDM switching fabric has persistent connections which provide connectivity between each ingress port and each egress port. Packets received at an ingress port are transmitted to one or more egress ports using TDM over one or more switching fabric connections. The congestion of each connection is monitored, and the capacity of the connection may be automatically adjusted based on the monitored congestion. Congestion may be indicated by a utilization of the connection or by a degree to which a buffer for storing packets to be sent over the connection is filled. Statistical multiplexing may be used at ingress ports and/or egress ports in order to eliminate idle packets. The utilization of the switch for data traffic may thus be improved over conventional TDM switches.
