Characteristics

 Standards

Functional

 ITU X24
The TRANSDATA interface is configured in MASTER or DCE mode.
It provides timing information: S clock for signal element timing and B clock for byte timing. It operates in "burst isochronous" operation with a nominal bit rate of 2048kbits/s: R/T transitions occur on OFF/ON transition of the S clock, R/T are sampled on ON/OFF transition of S. The S clock is held in the ON condition during idle time.
The data are transmitted according to the nominal transfer rate of the group of the switched TS's of the current BRI-PRI interface (n x 64 kbits/s).

Electrical

 RS422 / ITU V11.

Mechanical

 ISO 4903 for Clarinet-Book SCSI.
