Asynchronous data units (ADU)
ADUs are used with Data Line circuit packs to connect peripherals, such as
printers, data terminals, fax equipment, and call-detail recording equipment to the
DEFINITY. Figure 19 shows a typical Z3A2 ADU assembly (without a cable).
NOTE:
Data modules, PGATE boards, printers connected through data modules,
SATs connected through data modules, and anything related to the X.25
connectivity protocol are not supported on the S8300 or S8700 Media
Server platforms.
■ Add a female-to-male EIA-232 cable (shown) to make a Z3A1 ADU
assembly.
■ Add a female-to-female EIA-232 cable (not shown) to make a Z3A4 ADU
assembly.
