Data packet converter for video telephone system - converts series of data words at one bit rate to series of data words at another bit rate using FIFO data and control buffersThe input circuit (1) accepts signals from a data line (2), clock signal line (3) and a cell synchronisation ...
A number of standards are based on SDLC, including HDLC (High-Level Data Link Control), LAPB (Link Access Procedure B), LAPD, and LAPM. The main idea of SDLC is to avoid the time wasted by RS-232-C caused by gaps between successive characters. To eliminate that lost time, SDLC ...
The system comprises a hangul matrix unit (1) having numeric buttons and a converter (2) for initializing converting logic and controlliy the communication line when the hand set is lifted and converting phonemes to numbers when button-push is completed. The first to tenth Hangul consonants are...

Referring to the definition of the logmap given by equations (1) and (2), we can count the number of non-void pixels with ##EQU4## We want to use these l pixel values to modulate (unique carrier waves within the telephone band. At any particular frequency, there are two carrier wave...
the monthly price of basic service is positively related to the total number of channels contained in basic service and, in particular, to the number of major channels contained in the basic package. The evidence also suggests that customers purchase basic service to gain access to pay channels....
the search result is transmitted to the sender terminal to perform a normal telephone connection function. By using such a telephone domain, people can easily recognize the telephone number, there is an effect that can minimize the inconvenience caused by the telephone number change and telephone co...
is detected by providing the current transformer on the primary or secondary side of the transformer T.sub.1 and, to stabilize the output, the current is so controlled that it is rectified and smoothed before being fed back by an amplifier to the oscillation circuit of the DC/DC converter....
a switching network divided into an odd number exclusively of timedivision stages each including a plurality of switching matrices individually connectable in cascade with matrices of an adjoining stage to set up forward-signaling paths for the transmission exclusively of PCM message words from given in...
