Introduction

For a complete description of the communication formats, refer to the documents referenced on “References” in Chapter 1 “About ACC SNAPlus2 Link Software” of this manual.

Data transmitted at Level 2 over an SNAplus2 link via ACC is in the SDLC format. When a QLLC link is used the data transmitted at Level 3 is framed into standard X.25 packet format.

The scope of this Chapter is confined to activation of the SNAplus2 software, after which the ACC interface is merely a transparent or "pass-through" entity in the path.
