RS 232 is a serial interface port, which used mainly on PC’s , Modem’s and other devices which has RS-232 serial port used for remote monitoring purpose.
In Telecommunication field ,RS-232 is a standard for serial binary data interconnection between DTE(Data Terminal Equipment) and DCE (Data communication Equipment).
It is similar to ITU-T standard V.24. The abbreviation “RS” stands for “Recommended Standard”. TDA (Tone Access Data) is mainly used in the SDH equipment to transfer audio and data at 64 Kbps level.In Metro 1000 the TDA card consist of 12 voice channels and four RS-232 ports and four RS-422 ports
We will introuduce a method to test RS 232 interface of TDA card by using Hyper Terminal. it is simple and cost effective and save time. It will be convienient to read the attached file.
