The present disclosure provides a data processing method, an outdoor unit (IDU), an indoor unit (ODU), and a computer-readable storage medium. The method performed by an IDU communicating with an ODU may include: receiving an operation status signal from a user-side device; generating a Subscriber Line Interface Circuit (SLIC) event message corresponding to the operation status signal according to the operation status signal; generating a first SLIC control flow according to the SLIC event message, where the first SLIC control flow carries first label information corresponding to the SLIC event message; and sending the first SLIC control flow to the ODU, where the first label information indicates the SLIC event message which is processible to a voice protocol stack.

A payment terminal has a clock management unit for providing clock signals to components of the payment terminal. The payment terminal also has a wireless communication interface for communicating wireless signals. A processing unit of the payment terminal may monitor clock signals provided by the clock management unit and determine a phase and frequency difference between a clock signal provided to a component producing RF noise and a clock signal provided to a wireless communication interface of the payment terminal. When RF noise present in the received wireless signal falls below a threshold, the processing unit may sample the received wireless signal.

A method and a device for adjusting frequencies of intercom apparatuses are provided. The method includes: detecting, at a current operating frequency of a first intercom apparatus, an unknown speech signal sent from an intercom apparatus other than the first intercom apparatus, the first intercom apparatus communicating with at least one second intercom apparatus associated with at least one second terminal; determining a target operating frequency; and sending a first adjusting instruction instructing the first intercom apparatus to adjust the current operating frequency to the target operating frequency; and sending a frequency changing message to the at least one second terminal for controlling the at least one second intercom apparatus to adjust the current operating frequency to the target operating frequency.

On startup, a mobile station application will determine the current carrier network and submit a query to an application server that will return the correct location server configuration for the specified network. This information will be used on the mobile station to dynamically configure the device through the available GPS chipset API.

There is disclosed a communication device. The communications device includes an audio head unit for generating audio from an audio source, at least one speaker connected to the audio head unit for audibly generating audio provided by the audio head unit, and an intercom system, linked to the audio head unit, for receiving intercom audio for broadcast over one or more a wired or wireless intercom headset, and broadcasting the intercom audio for receipt by the one or more wired or wireless headset.
