Pacing

A method for controlling call flow. In a pacing algorithm, mathematical rules are established to control the rate at which calls are placed by an automatic dialing machine using momentary sampling techniques to forecast the rate of pacing or dialing.

Packet

A small group of digital bits that is routed through a network to their destination. The bit sequence of the packet (field structure) of a packet may be arranged to include the destination address in addition to the data that is being transported and other data such as the packet originator and error protection bits.

Packet Assembler And Disassembler (PAD)

The PAD divides or converts blocks of data (such as data files) to and from small packets of information. In the disassembly process, a PAD usually assigns sequential numbers to the packets as they are created to allow the reassembly PAD to identify the correct sequence of data packets to reproduce the original data signal.

This diagram shows a packet assembler and disassembler (PAD) system operation. This diagram shows that a large file is to be sent over a packet data network. The large file is supplied to the PAD circuit that divides the data file into smaller packets. These packets are sent toward their destination through a data communications network. When they are received, the are reassembled into the original large data file by a packet assembler.
