Patent number: 8472432Abstract: There is provided herein a system and method for automatic configuration of data routings for use with electronic data such as phone calls, faxes, etc. In an exemplary embodiment, when more than one carrier might potentially terminate the transmission, the carriers are ordered based on some screening criterion (e.g., transmission price). Data transmissions are then assigned to the carriers based on the sorting order, with the second place and lower carriers (e.g., the higher priced carriers) not being selected unless the first carrier cannot complete the transaction. The switch instructions necessary to implement this scheme may be generated automatically.Type: GrantFiled: August 31, 2009Date of Patent: June 25, 2013Assignee: Level 3 Communications, LLCInventors: Michael F.

Publication number: 20130089086Abstract: Implementations of the present disclosure involve an apparatus and/or method for a regional independent tandem switch of a telecommunications network. The tandem switch processes communications between a long distance carrier and a local exchange carrier through a voice over IP (VOIP) network. By utilizing the VOIP network, the regionally independent tandem may process long distance communications to and from any point in the network, regardless of the physical proximity of the tandem to the originating/destination communication device. The regionally independent nature of the tandem also allows for flexibility in communication routing through the network, load balancing between the network tandem switches and reduction of needed components of the network for proper processing of the long distance communications.Type: ApplicationFiled: October 11, 2011Publication date: April 11, 2013Applicant: Level 3 Communications, LLCInventors: Christopher Sayer, Rogier Ducloo, Richard Terpstra

Patent number: 8417114Abstract: Systems, methods, and devices are disclosed for monitoring optical communications between a managed location and a remote location. In particular, an optical signal is transmitted over an optical fiber and passed-through a test device. A portion of the optical signal is filtered from the original optical signal and passed to a monitoring unit. The monitoring unit may instruct one or more switches in the test device to loop the optical signal back toward the managed location. Subsequently, testing and monitoring may be performed at the managed location. The device may provide a test output or may transmit the information to the managed location.Type: GrantFiled: August 21, 2012Date of Patent: April 9, 2013Assignee: Level 3 Communications, LLCInventors: Jeffrey Kendall Storey, John F.

Patent number: 8416769Abstract: An open architecture platform bypasses data from the facilities of a telecommunications carrier, e.g. an incumbent local exchange carrier, by distinguishing between voice and data traffic, and handling voice and data traffic separately. An SS7 gateway receives and transmits SS7 signaling messages with the platform. When signaling for a call arrives, the SS7 gateway informs a control server on the platform. The control server manages the platform resources, including the SS7 gateway, tandem network access servers (NASs) and modem NASs. A tandem NAS receives the call over bearer channels. The control server determines whether the incoming call is voice traffic or data traffic, by the dialed number, and instructs the tandem NAS how to handle the call. Voiced traffic is transmitted to a switch for transmission from the platform. Data traffic is terminated at a modem NAS, where it is converted into a form suitable for a data network, such as a private data network or an Internet services provider (ISP).Type: GrantFiled: May 17, 2010Date of Patent: April 9, 2013Assignee: Level 3 Communications, LLCInventor: Shawn M.
