Abstract

The invention discloses a method, device and system for realizing communication. The method comprises the following steps that an orderwire telephone detects off-hook, judges that the orderwire telephone is in a standby state, sends a communication requesting signalling to an orderwire telephone set composed of orderwire telephones connected with various ports in a timed manner, and updates the state to an off-hook ring-back state; and the orderwire telephone realizes communication with the orderwire telephone sending a communication answeringsignalling while receiving the communication answeringsignalling from one orderwire telephone in the orderwire telephone set. By means of the invention, communication is simply realized; and communication is not limited by a ring network topological structure composed of SDH equipment.

Description

technical field

[0001] The present invention relates to the technology of official telephone, in particular to a method, device and system for realizing a call. Background technique

[0002] The business phone occupies an important position in the Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) network, and is mainly used for communication between various sites in the network, which is convenient for maintenance personnel to solve problems in the process of opening and maintenance management of SDH equipment. to communicate. With the continuous improvement of the performance of SDH equipment, people's requirements for official telephones are getting higher and higher. First, the official telephone is required to have high reliability, so that when the SDH equipment fails, normal official communication can be guaranteed; The call quality is good and the function is multi-functional.

[0003] Existing official telephones implement calls based on Internet P...

Embodiment Construction

[0116] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0117] see figure 1 , the present invention proposes a method for realizing a call, including:

[0118] Step 100, the business phone detects the off-hook, and judges that it is in a standby state before the off-hook, and regularly sends call request signaling to the business phone group formed by the business phones connected to each port through its own ports, and sends The state of itself is updated to the off-hook ringback state.

[0119] In this step, the service phone can use the known technology of those skilled in the art to detect whether to pick up ...
