A distributed digital cross-connect system () is provided. The system includes two or more network interface islands () that connect to the telecommunications network. The system () also includes one or more distributed services nodes (). Each distributed services node () connects to two or more of the network interface islands (). The network interface islands () can transmit data to each other through the distributed services node (). An administration system () is also connected to each distributed services node () and each network interface island (). The administration system () transmits matrix configuration and telecommunications channel routing data to the network interface islands () and the distributed services nodes ().

Distributed digital cross-connect system and method

A timing system for distributing a timing signal includes a master timing system that receives a network timing reference. The master timing system generates a master timing signal from the network timing reference. A distributed services node timing system receives the master timing signal and embeds a timing signal into a data transmission frame. A network interface island receives the data transmission frame and retrieves the embedded timing signal therefrom.

Timing system and method for distributing a timing signal

A distributed digital cross-connect system (,) is provided. The system includes two or more network interface islands (,) that connect to the telecommunications network. The system (,) also includes one or more distributed services nodes (,). Each distributed services node (,) connects to two or more of the network interface islands (,). The network interface islands (,) can transmit data to each other through the distributed services node (,). An administration system (,) is also connected to each distributed services node (,) and each network interface island (,). The administration system (,) transmits matrix configuration and telecommunications channel routing data to the network interface islands (,) and the distributed services nodes (,).

A distributed digital switching system is provided that includes a plurality of service controllers (20) which are interconnected to each other through a network (10). A network arbitrator is provided that controls the flow of traffic on the network (10). Each of the service controllers (20) is operable to provide a switching configuration between inbound data to the service controller (20) and network terminations associated with each of the service controllers (20). A processor (150) on each of the service controllers (20) controls the operations thereof with the voice information stored in a memory (208) which can be configured with a circuit (204). Each of the service controllers (20) has associated therewith a conference circuit for defining and creating a conference that can access all inbound data and provide interconnections therebetween and output this on a single outbound conference channel. There can be multiple conferences created at each service controller (20). Each of the conferences on the network can be accessed with a single associated conference address, such that only one address need be defined on the network for a given conference.

Programmable distributed digital switch system

A timing system (100) for coordinating the components of a distributed digital cross-connect system (10) is provided. The timing system (100) includes a master timing system (102) that receives a network timing reference (98, 99) and generates a master timing signal. A distributed services node timing system (104, 106) is connected to the master timing system (102) and receives the master timing signal. The distributed services node timing system (104, 106) then embeds a timing signal in a data transmission frame (150). Two or more digital cross-connect timing systems (108) are connected to the distributed services node timing system (104, 106) and receive the data transmission frame (150). The digital cross-connect timing systems (108) retrieve the embedded timing signal from the data transmission frame (150).

System and method for controlling timing in a distributed digital

A message transport network (10) is provided for high speed switching between processing elements (72, 80). Clusters of low speed processing elements (72) may be connected to the message transport network (10) through a transport node controller (78). The transport node controller (78) and the high speed processors (80) are connected to the gateways (82). A pair of gateways (82) may be connected through a transport interchange node (106) to allow communication between processors (72, 80) associated with the gateways (82). A transport interchange supervisor (98) maintains a record of the status of each gateway (82) and generates commands to form connection between gateways (82) in the transport interchange node (106). A maintenance controller (102) and system maintenance processor (76) oversee the validity of the data being passed through the system on paths independent of the data transfer paths. The message transport network (10) may be used in variety of applications, such as a telephony switch (11), a signaling transfer point system (21) or a fault tolerant minicomputer (49).
