A system for sending data in an optical network comprising a plurality of source nodes and destination nodes is disclosed. In one aspect, a source node generates, in a spectral band that is associated with it, a multi-carrier optical data signal obtained by modulation of a source signal at a source wavelength and sends it in the form of single-band data bursts that can be associated with distinct source wavelengths. A single-band data burst comprises, in addition to payload data symbols (PL), a sequence of learning symbols (TS) composed of a plurality of learning symbols. A control unit belonging to the control plane of the optical network determines, for at least one of the source nodes, instants of sending of the single-band data bursts and source wavelengths to be used for sending these single-band data bursts, as a function of a path time of the data bursts between the source node and one of the destination nodes associated with the source wavelength. The control unit also determines the size of the sequence of learning symbols (TS) of the single-band data bursts.

A method for using a code division multiple access (CDMA) subscriber unit to transmit a communication to a base station at a first data rate using at least one communication channel, determine an adjusted data rate desired for support of the communication, and transmit the communication to the base station over a second channel at a second data rate, wherein the first data rate is different than the second data rate.

Systems and methods receive control signal(s) from an interconnected data platform of a third-party to initiate display of digital images that are customized for an individual, the digital images including an image that includes a link to access a previous interaction between the individual and an agent. Distributed access to the digital images accessible via multiple platforms is regulated via one or more multiplex communication protocols, with each of the multiple platforms including a respective displayable interface for displaying at least some of the plurality of digital images during an interaction between the individual and a user. An indication of a user selection, by the user, of the link is received, and based on receiving the indication, information about the previous interaction is routed to a computing device of the user that is accessing a platform of the multiple interface platforms.
