Implementations described and claimed herein provide systems and methods for intelligent node type selection in a telecommunications network. In one implementation, a customer set is obtained for a communications node in the telecommunications network. The customer set includes an existing customer set and a new customer set. A set of customer events is generated for a node type of the communications node using a simulator. The set of customer events is generated by simulating the customer set over time through a discrete event simulation. An impact of the customer events is modeled for the node type of the communications node. The node type is identified from a plurality of node types for a telecommunications build based on the impact of the customer events for the node type.

Systems and methods for volume control over intercom trunk lines. One example method includes receiving, from a first keypanel coupled to a first intercom, a call request identifying a remote keypanel coupled to a second intercom. The method includes transmitting a trunk request based on the call request and receiving a trunk setup message. The method includes activating a first crosspoint to provide a two-way audio connection between the first and second intercom devices. The method includes applying a trunk gain value to the first crosspoint based on the remote keypanel and transmitting, with an audio gain based on the trunk gain value, an audio stream received from the first keypanel. The method includes receiving, from the second intercom, a gain adjustment value associated with the first keypanel and the remote keypanel and applying an adjusted trunk gain value to the first crosspoint based on the gain adjustment value.

An input unit (20) is connectable to a programmable controller (10) and an output unit (30) to share a shared time with the programmable controller (10) and the output unit (30). The input unit (20) includes a data sharer (220) that shares, in a periodic time segment defined by the shared time, data in a storage area (214) with the programmable controller (10) and the output unit (30), and an input (240) that acquires input information input from an input device (20A). The data sharer (220) transmits, in the periodic time segment, transmission information to the output unit (30). The transmission information is the input information or indicates a result of a predetermined computation process performed on the input information.

An error recovery method performed in an end node of an Ethernet-based vehicle network includes: detecting, by a physical (PHY) layer processor of a PHY layer of the end node, a physical error of a message, when the message is received at the PHY layer of the end node; detecting, by a controller processor of a controller included in the end node, a logical error of the message; and classifying, by the controller processor, types of the physical error and the logical error.

Asynchronous and/or synchronous zero charge telephony protocol systems and methods may include an asynchronous signaling switch and/or a call duration time quota from a synchronous charging onset to place and complete a call. A first device call request is received with a second device mobile address. The asynchronous systems include instructions to automatically modify the mobile address with a routing prefix when the first device has insufficient balance or independent of balance, route to the asynchronous signaling switch based on an associated modified address trunk path, revert the modified call signal at the asynchronous signaling switch to the call signal, and deliver and automatically disconnect the call immediately when the call is completed. The synchronous systems include instructions to automatically set the call duration time quota upon insufficient balance, and deliver and automatically disconnect the call from the second user mobile device when the call is completed and the call duration time quota is exceeded.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

A Toll-Free Management Platform (TFMP) includes methods and systems for number administration, customer administration, call management services, texting services and text registry, and a smart services registry. The TFMP may allow users to receive through a web-based interface, an activate request from a user, wherein the request includes at least a customer record template reference and an indication of when to active a toll-free telecommunications number associated with the request. The request may include at least one IP address datum associated with the toll-free telecommunications number. A user interface may allow activating a toll-free number, and users may access the TFMP to create and access existing templates of toll-free call routing templates, and utilize a routing tree engine to create customized call routing trees for the toll-free numbers of interest to the user.

Methods and architectures for improving operation of 9-1-1 and other emergency services networks. Enriched data (e.g., text messages, videos, phase II location information, etc.) may be transmitted to a PSAP via a secondary communication channel (i.e., data), wherein the primary communication channel is a voice telephony trunk. Disclosed embodiments may increase the speed with which accurate location information is made available to improve call routing accuracy and decrease dispatch time. Some embodiments may also enable continued operation of legacy emergency services systems during and after transition to next generation systems.

Certain aspects of the disclosure are directed to control of data communications services. According to a specific example, an apparatus is provided including one or more computer processor circuits configured and arranged to interface with remotely-situated client entities using a first programming language used by a data communications server, and to provide a database of communications services to the client entities. The apparatus further includes communications control circuitry configured and arranged to control communications routing for each respective client entity, by identifying, client-specific sets of control data derived from programming instructions received over a network and corresponding to a second programming language that is compatible with the first programming language, and providing the communications services to end-users of the client entity based on the client-specific sets of control data including particular routing functions for emergency notifications.

A first computing device may receive an indication of user input that is at least a part of a conversation between a user and a first assistant executing at the first computing device. The first assistant and/or an assistant executing at a digital assistant system may determine whether to handoff the conversation from the first assistant executing at the first computing device to a second assistant executing at a second computing device. In response to determining to handoff the conversation to the second assistant executing at the second computing device, the first assistant and/or the assistant executing at the digital assistant system may send to the second computing device a request to handoff the conversation which includes at least an indication of the conversation.
