Amphenol DS26401

the ds26401 is an octal, software-selectable t1, e1, or j1 framer. it is composed of 8 framer/formatters and a system (backplane) interface. each framer has an hdlc controller that can be mapped to any ds0 or fdl (t1)/sa (e1) bit. the ds26401 also includes a full-feature bert device, which can be used with any of the 8 t1/e1 ports, and an internal clock adapter useful for creating synchronous, high-frequency backplane timing. the ds26401 is controlled through an 8-bit parallel port that can be configured for nonmultiplexed intel or motorola operation.
