ZCOM Software Overview

ZCOM Software Overview

Figure 1-1 on page 14 presents an architectural overview of the ZCOM Subsystem.

The ZCOM application interface provides low level access to the ZCOM Subsystem. Application programs make requests via the ZCOM library routines which are then communicated to the firmware on the ACC Mux card via the HP-UX drivers.

The firmware which runs on the ACC Mux card includes the ZCOM Mux kernel software plus ZCOM protocol modules. The ZCOM protocol modules provide the protocol specific firmware that runs on the ACC Mux card.

Note that the highlighted area in Figure 1-1 shows which software components are provided by the base ZCOM Subsystem. Only protocol modules used for loopback testing, and for monitoring the health of the ACC Mux card and panel are provided with the base ZCOM Subsystem. Protocol specific modules, such as X.25, are added to the ZCOM Subsystem as separate products. The Protocol User’s Guides provided with these products must be used in conjunction with this Programmer’s Reference Guide when writing ZCOM application programs.
