scope:

This American National Standard specifies a physical-level interface for transmitting digital data at 800 Mbit/s or 1600 Mbit/s serially over fiber-optic cables across distances of up to 10 km. The signalling sequences and protocol used are compatible with HIPPI-PH, ANSI X3.183-1991, which is limited to 25 m distances. HIPPI-Serial may be integrated as a host's native interface, or used as an external extender for HIPPI-PH ports.

Specifications are included for:

- the encoding and serialization of the parallel data;

- the sequence of signals required for link reset;

- the timing and optical requirements of the serial signals;

- 32-bit (800 Mbit/s, 100 MByte/s) and 64-bit (1600 Mbit/s, 200 MByte/s) operation;

- simplex and dual simplex operation.
