Abstract: Aggregate processing of information during network transmission. Information requests are redirected to cause the information to be returned to a processing node where processing takes place before the processed information is returned to the requester. Redirection for processing may be initiated by the requester, or may be initiated on behalf of the requester. Processing nodes may be distributed. Processing requests may be nested so that after a first processing action takes place on data flowing through the network, a second processing action takes place.

Abstract: 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).

Abstract: In a private branch exchanger which is connected to an ISDN network, a virtual private line information table stores information indicating channels corresponding to virtual private lines in units of routes. An identifying unit determines a route in response to an event, refers to the virtual private line information table based on the determined route to determine a specific one of the channels corresponding to the virtual private lines for the determined route. Also, the identifying unit determines whether a connection of a specific virtual private line corresponding to the specific channel to an ISDN network is established. When the specific channel corresponding to a specific virtual private line is usable, the identifying unit issues a communication instruction. A communication unit performs communication using the specific channel corresponding to the specific virtual private line in response to the communication instruction.

Abstract: A method of synchronizing a base station and a remote station is presented. The base station is communicatively coupled with the remote station and a reference network. The base station clock signal is compared with a reference clock signal derived from the reference network and adjusted accordingly.

The remote station compares the clock signal with the timing information and adjusts the clock signal accordingly. This is done without reference to an external clock.

Abstract: Digital code words are transmitted via a digital communication network, e.g. from a digital modem (1) to an analog modem (5). Whenever an RBS technique is used for an RBS channel, a given bit, as a rule the LSB, of a corresponding code word is changed. In order to recognize and correct such RBS channels, training code words transmitted during a training phase are evaluated. If an RBS channel is detected, the given bit of the corresponding code word is set to a fixed value.

Abstract: A procedure for providing a telecommunication service. The service provisioning system (SDS) is equipped with a global service control point (GSCP1, GSCP2) and several service switching points (SSP1 to SSP3). Subscribers (A) of the telecommunication network (T_NET) send service request messages to service control functions, which control the implementation of the respective telecommunication service. The service provisioning system is also equipped with one or several local service control points (LSCP1 to LSCP4), whereby each of them is assigned to one of the service switching points (SSP1 to SSP3) and is connected via a local communication mechanism (L_NET1 to L_NET3). Depending on the telecommunication service being controlled, the service control function is installed globally or locally. The service switching point (SSP1 to SSP3) establishes whether the assigned service control function is currently installed locally or globally, and transfers the service request message accordingly.

Abstract: A serial/parallel converter 2—converts a B channel data in an ISDN into an 8-bit parallel data and outputs it to a latch circuit 3. A comparator 4—compares an octet data latched by the latch circuit 3 with a preset idle pattern and, when the octet is different from the preset idle pattern, outputs a disaccord signal to a pulse generator 5. When an idle pattern appears continuously on the B channel, a timer circuit 6 outputs a significant signal. With using the significant signal from the timer circuit 6, it is possible to judge that the B channel is in non-use state, so that it can be determined by the simple circuit construction whether or not the B channel is in the use state.

Abstract: A control link establishment code sequence for interrogating a network element interface (NEI) device terminating a local digital data services loop of a telecommunications network has an in-band code exclusive of codes currently employed to represent functional operations to be executed by a channel unit. Once a virtual link is established, a command—response mode session is conducted. To provide for byte alignment over the local loop for remote provisioning protocol employed at various violation mode rates, each command—response code byte is repeatedly transmitted, and a ‘delimiter’ byte is interleaved with successively repeated ones of the same code byte. Response messages from the NEI device also have code repeats interleaved with the delimiter byte.
