Recording equipment for program-controlled telephone or magnet telephone

Abstract

The invention discloses recording equipment for a program-controlled telephone or a magnet telephone, comprising a machine body. At least one group of telephone line access ports and mode switches arearranged on the machine body, wherein the mode switches are connected with the telephone line access ports in a one-to-one correspondence manner, the mode switches are used for switching the corresponding telephone line access ports into a program-controlled telephone mode or a magnet telephone mode, and a signal conditioning circuit, an information decoding circuit, a data conversion circuit, adata processing circuit and a data management circuit are arranged in the machine body. According to the invention, telephone information analysis can be carried out on two different telephone modes of a program-controlled telephone or a magnet telephone by one recording device; and the analyzed telephone voice information is compressed and stored in the data management circuit in the machine body, so that the storage space of the data management circuit is saved by analyzing the compressed data, Meanwhile, the working efficiency during data reading is improved by the compressed telephone voice information.

Description

Technical field [0001] The invention belongs to the technical field of recording equipment, and specifically relates to a recording equipment oriented to a program-controlled telephone or a magnet telephone. Background technique [0002] Program-controlled telephone refers to a telephone connected to a program-controlled telephone exchange. A program-controlled telephone exchange is an exchange controlled by an electronic computer. It uses a pre-programmed program to control the connection of the exchange. Program-controlled telephone has the advantages of fast connection speed, multiple business functions, high efficiency, clear voice, and reliable quality. [0003] Magnet phones are usually used in the sections along the railway. They use a magnet-type hand-cranked generator as a ringing signal source and are equipped with a call power supply. They have simple structure, low requirements on lines and switching equipment, long service life, stable performance, and call Features s...

Problems solved by technology

[0005] At present, the existing telephone recorders on the market are only used for program-controlled telephones, and can be used without supporting program-controlled telephones or magnet phones. The information decoding and voice data of program-controlled telephones are usually transferred to the central processing unit after analog-to-digital conversion. (CPU) hardware platform processing, the size of the phone information data cannot be effectively compressed, wasting storage space and also affecting the management efficiency of the phone information data
