Problems solved by technology

However, the boards of the frame-type communication equipment are closely arranged. When connecting the serial port cable to the debugging serial port connector of the line card board or the network board, the board on the adjacent upper layer must be unplugged, which will destroy the problem environment.
[0004] However, the internal structure layout of each single board and the inter-board structural layout of each single board of the frame-type communication equipment are complex overall designs. Therefore, it is necessary to provide a method to debug the physical position of the serial port connector in the board without modifying the line card board or the network board, and obtain the line The serial port signal of the debugging test of the card board or the network board

Abstract

The invention provides a signal transmission method and device. The signal receiving method comprises the steps that a programmable logic device of a main control board receives a serial port signal through an RRPP channel connected with a backboard and outputs the serial port signal through a serial port connector of the main control board; the RRPP channel enables the serial port signal to be received; the programmable logic device receives a specified lead code for receiving a lost Rlot signal through the RRPP channel to enable the serial port signal to be received through the RRPP channel,and starts to receive the Rlot signal; the programmable logic device judges whether the last bit of the received Rlos signal is a stop bit or not; and if so, the programmable logic device determinesthat the receiving of the Rlos signal is completed, and enables the serial port signal to be received through the RRPP channel.

Description

technical field [0001] The present application relates to communication technology, specifically to a signal transmission method and device. Background technique [0002] In a frame-type communication device, the main control board, each line card board, and network board have independent debugging serial ports. However, in the frame-type communication equipment architecture, the serial port connector of the main control board is directly connected to the external physical debugging device, but the debugging serial port of the line card board and the network Physically debug the device. [0003] During software debugging or environmental testing, when the CPU program of the line card board or network board fails to run, it is necessary to connect the board debugging serial port connector of the line card board or network board to the printer through a serial cable to view the printed information. However, the boards of the frame-type communication equipment are closely arr...
