APPLICATION NOTE 301
Legacy T1/E1 8MHz Backplane Operation

Abstract: This application note provides the requirements for multiplexing four PCM streams into one 8MHz
system backplane using Dallas Semiconductor/Maxim SCTs and framers that do not contain interleave bus
operation (IBO) modes internally.The DS2155, DS26528, DS26524, DS26522, DS26521, DS26519 and
DS26518 all contain IBO functionality without external circuitry and are recommended for new designs.
