Packet assembler/disassembler
Appearance
A Packet Assembler/Disasembler (or PAD for short) is a device which handles the packet assembly in a packet switched network. PADs are extremely flexible devices; they handle to configure a computer's port to suit a special equipment, both as to speed and screen addressing, rather like a Bulletin Board System (BBS). To be accurate, it is the BBS which mimics the PAD.
Computer users usually use a PAD when they own a terminal without packet-creating capabilities, and connect to a special PSS facility which handles the packet assembly for him.
