Embodiment Construction

[0029] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] A preferred embodiment of the new ring current control method of the present invention is to collect the ring current detection signal of the board, the ring current signal of other single boards, the power-on signal, the ring current signal of the backboard of the communication equipment frame, and the single board in place. Signals, single-board insertion signals, etc., are judged through logical combinations to control the disconnection and conduction of the switch circuit, and control the ringing current output and ringing current mutual aid switching. Sequence control is added to the control to avoid hard switching of switching devices, and at the same time, the ringing current control circuit is transferred from the backplane of the communication equipment frame to the single board of the ringing current device, which impr...

Abstract

The present invention discloses communication equipment ringing current controller used in clip-in adapter support backboard. Said communication equipment backboard set has at least one ringing current equipment single board use for through at least one switching circuit providing ringing current to said user board; wherein said device having at least one control single board with at least one control unit and said switching circuit, said control unit use for controlling said switching circuit on-off. Said invented method for and device adopt MCU or logic or logic chip detecting said ringing current signal, backboard ringing current signal and mutual sent signal, and sequential control sequential control, avoiding switch device hard switching and arcking, raising switch device and backboard reliability.

Description

technical field [0001] The invention relates to a communication device and a control method thereof, in particular to a ring current control device and method in the communication device. Background technique [0002] In the communication equipment of the prior art, the ring current of the user's phone is mainly provided by the ring current equipment of the communication equipment. At present, the common method is to switch the ring current to the corresponding user board through the control circuit, and then pass the user The board sends the ring current to the corresponding user's phone. [0003] The existing ringing current scheme of communication equipment mainly adopts to place switch circuits on the backboard of the communication equipment subrack, and the ringing current generated on the single board of the ringing current equipment is transmitted to the corresponding users through the corresponding switching circuits on the backplane of the communication equipment su...
