DS26556 4-Port Cell/Packet Over T1/E1/J1 Transceiver www.maxim-ic.com GENERAL DESCRIPTION The DS26556 is a quad, software-selectable T1, E1, or J1 transceiver with a cell/packet/TDM interface. It is composed of four framer/formatters + LIUs, and a UTOPIA (cell), POS-PHY™ (packet), and TDM backplane interface. Each framer has an HDLC controller that can be mapped to any DS0 or FDL (T1)/Sa (E1) bit. The DS26556 also includes full-featured BERT devices per port, and an internal clock adapter useful for creating synchronous, high-frequency backplane timing. The DS26556 is controlled through an 8-bit parallel port that can be configured for nonmultiplexed Intel or Motorola operation.
