3.2 OXIO PRIMARY SYSTEM
A correctly functioning OXlO, release 3.4, is required to operate
the communications package at a primary station. Also, a four-
channel communications controller (FCCC) board must be prepared
and installed in the system. The following paragraphs describe

Building a DXlO system with HDLC communications capabilities
requi res that the FCCC OSR be incl uded in OXIO system generation
to provide the interface between the host software and the FCCC
software. The following steps are necessary to accomplish DXlO
s yst em generation wi th the FCCC DS R:
1. Preparation and installation of the FCCC board (see
par a gr a ph 3 • 2 • 2) •
2. Installation of the HOLC communications obj ect files
using the procedures gi ven in the DXlO HOLC
Canmunications Package Object Installation Guide. The
principal steps in this procedure are as follows:
a. Patching the GEN990 task for DXlO systems,
releases 3.4.1 and earlier. This step is not
required for OXIO systems, release 3.4.2 and
later.
b. A OXIO operating system generation using the XGEN
utility.
c. Execution of the communications DSR installation
procedure for FCCC device service routine
generation.
d. Assembly and linkage of the new operati ng system
using the ALGS (Assemble and Link Generated
Sys t em) comm and.
e. Application of the patch file using the PGS
(Patch Generated System) command.
f. Application of patches to enable the SVC >40
processor for the HDLC package using the XPS
(EXecute Patch Synonym Processor) command.
