The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
it has burger vector which lie in interface plane not parallel to dislocation line..
Virtual teletype (VTY) is a command line interface (CLI) created in a router and used to facilitate a connection to the daemon via Telnet, a network protocol used in local area networks.To connect to a VTY, users must present a valid password.The VTY interface has three restricted mode commands:VTY View: Enables read-only interface accessVTY Enable: Enables read-write access to the CLIVTY Other: Includes modes like Trivial File Transfer Protocol (TFTP)VTY uses a set of CLI command actions, which depend on the three types of actions CLI can perform:MovementEditingAdvanced
The PDH interface standard is not uniform,there is 1.5Mbps and 2Mbps. The PDH system have not strong management function.
A diagram showing the connections, line terminations, etc. needed to connect a specific type of signal interface to a system.In addition to this diagram a tabular entry giving signal specifications, connector types, etc., a figureshowing installation and mating of connectors, and a textual description of the purpose and usage of the interface are usually required in formal documentation.During my avionics career I have had to work with systems having several thousand signal interfaces, thus requiring all of those thousands of diagrams, tabular entries, figures, and textual descriptions to appear in the Interface Control Document (ICD) for that system. Many ICDs were well over a foot thick.Note: documents like the Software Description Document (SDD) on these systems could get over five feet thick!
Short answer is yes. It does require some interface circuitry, which can be found at www.8052.com

The Atmel AT89S52 is a microcontroller in the 80C51 family.
can we replace AT89c51 by AT89s52 but i have c51 code
maximum 232
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
semi conductor
32
Its an I\O controller
AT89S52 is a microcontroller based on the Intel 8051 architecture and features. Concerning your question, AT89S52 is the heart of most project involving Dual Tone Multi Frequency (DTMF), that is to say it is the controller IC used in such project.
max means maxim which make ic's
S stands for SEMI CONDUCTOR
