A method for determining the security level associated with transmissions in a telecommunications network includes means for alerting parties of the security status of the transmission. When a route interconnecting the parties includes an insecure link, an alert is provided so that the parties are aware of the insecure nature of the call before communications begin. Alternatively, the parties may elect to decline or alter content of the communications to preserve integrity.

Method for determining the security status of transmissions in a telecommunications network

A method and apparatus for controlling telecommunications call processing is disclosed. In a switching system, a Master Controller is provided for maintaining the database of the system, and for receiving call processing control messages. The Master Controller receives these messages via a core switching fabric network of the switching system. The Master Controller selects one of a plurality of feature processors, the feature processors being of several types for processing different features, to process the received call processing message. The Master Controller, if necessary, transmits not only the call processing message, but also state information about the call to the selected feature processor. The feature processor processes the message, and returns call state update data to the Master Controller. The feature processor also transmits messages for controlling other units in order to implement the desired response to the received call processing message. Advantageously, the centralized Master Controller allows a plurality of different types of feature processors to be used, and maintains a record of which feature processors are performing properly so that call control messages are only sent to working feature processors. Advantageously, a single database (duplicated for reliability), is maintained for a plurality of different types of feature processors.

A telephone switch-integrated modem pool and broadband access concentrator provide improved data network access through a PSTN local loop. Rather than simply cascading data as TDM traffic through the PSTN, plural switch-integrated modems, a broadband access concentrator, and a broadband pipe are used to route data traffic between local loop subscribers and one or more data network service providers. Advantageously, point-to-point connections are maintained between subscriber and service provider equipment in order to enable continued use of high level subscriber-provider protocol service negotiation (such as PAP/CHAP, NCP and the like). LCP (link layer) management and translation between the asynchronous subscriber-modem pool link and the synchronous provider-modem pool link are handled transparently by the broadband access concentrator.

A universal line card architecture includes core circuitry for performing battery, overvoltage, ringing, supervision, coder/decoder circuit (CODEC), hybrid and test (BORSCHT) functions interconnected to a control processor and processing system. The control processor and processing system serve a plurality of line cards and are configurable to one or more of a plurality of subscriber loop standards in which the line card can operate. Upon receipt of instructions from a configuration system, the processing system configures line card and core network interface elements so that an appropriate subscriber loop standard may be associated with the line card identified in the provisioning request.

It is desirable to be able to recognize data calls so that different charges can be applied to such calls and that vertical services, such as the use of special transmission facilities, may be offered to data callers. This recognition is accomplished by attaching a tone detector to a call in order to detect the special tones characteristic of a data call. Advantageously, this permits different charges to be imposed on data calls.

System and method for special call detection and billing treatment

A system and method are disclosed for implementing support for increased communication speed between data communication devices, including one or more high speed analog modems, connected to a digital communication network. The high speed analog modems communicate with the digital communication network via analog signaling pathways that also support voice communication across the digital communication network. Following the initiation of communication between an originating communication device and a terminating communication device connected to the digital communication network, determination is made as to whether the communication devices include at least one high speed analog modem and another data communication device capable of communicating at the increased data communication speed. If so, adjustment is made, as necessary, to the filtering present on the analog signaling pathway between the digital communication network and the analog modem to increase the analog signaling bandwidth that can be carried thereon. Data communication speed is further increased by implementing a companding mode that is substantially linear across the voltage range of the analog signals being sampled, or in which larger quantization spacings are used for lower voltage levels than for higher voltage levels.

High usage lines in a telecommunications system must be detected to avoid local areas of high call blockage. Such high usage lines are frequently lines that originate or receive data calls. The presence of a data call is detected by testing for a signal, such as a tone, on the call connection after an answer signal has been detected, and testing to see if the duration of the call exceeds some predetermined quantity. Lines which originate or receive data calls exceeding the predetermined quantity are then monitored to measure their usage. Advantageously, many high usage lines can be detected by monitoring only the relatively few lines that originate or receive data calls.
