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.
