X.3

X.3 is an ITU-T standard indicating what functions are to be performed by a Packet Assembler/Disassembler (PAD) when connecting character-mode data terminal equipment (DTE), such as a computer terminal, to a packet switched network such as an X.25 network, and specifying the parameters that control this operation.

The following is list of X.3 parameters associated with a PAD:
*1 PAD recall using a character
*2 Echo
*3 Selection of data forwarding character
*4 Selection of idle timer delay
*5 Ancillary device control
*6 Control of PAD service signals
*7 Operation on receipt of break signal
*8 Discard output
*9 Padding after carriage return
*10 Line folding
*11 DTE speed
*12 Flow control of the PAD
*13 Linefeed insertion after carriage return
*14 Padding after linefeed
*15 Editing
*16 Character delete
*17 Line delete
*18 Line display
*19 Editing PAD service signals
*20 Echo mask
*21 Parity treatment
