PART I

∙Chapter 2 — Communications System Networking — An Overview— Introduces the networking software packages that are used to implement a PBX network. Included is a matrix that maps node administration to the tools used given the type of switch and switch version.

∙Chapter 3 — Tandem Tie Trunk Networks — Defines tandem tie trunk networks and describes how they operate.

∙Chapter 4 — Main-Satellite/Tributary (MS/T) — Describes the MS/T configurations, features, and engineering and administration considerations.

∙Chapter 5 — Electronic Tandem Network (ETN) — Describes the ETN configurations, features, interactions with other types of networks (including Centralized Attendant Service networks and the Software-Defined Network), and ETN engineering and administration considerations.

∙Chapter 6 — Distributed Communications System (DCS) — Describes the DCS configurations, transmission facilities, features, feature transparency, and engineering and administration considerations.

PART II

∙Chapter 7 — Data Connectivity — An Overview — Describes general data communication concepts and capabilities, as well as defines the basic data communications features provided that your communication system provides.

∙Chapter 8 — Data Communications Capabilities — Describes how to use a communications system to connect data terminal equipment, local area networks, public and private data networks, and telecommunication hosts.

∙Chapter 9 — Data Communications Configurations — Provides template configurations for various data networking applications, e.g., medical imaging, FAX communication, file transfers, and so forth.

∙Appendix A— Related Documents — Lists the names of documents related to DIMENSION, System 75/85, and the DEFINITY Generic 1 and Generic 2 communications systems.

∙Appendix B — Timing and Synchronization — Provides detailed information on synchronization in the private switching systems within a network. This appendix also provides many examples of how and where synchronization is used.

∙Appendix C — Trunking Terms and Trunk Compatibilities — Provides a list of trunking terms and several tables that identify trunking compatibility between particular types of switches.

∙Appendix D — Protocols — Explains the open system interconnect (OSI) protocol model, describes protocol naming systems, defines some of the most widely implemented protocols, and describes DCP, DMI, and BX.25 proprietary protocols.

∙Appendix E — Lead Designations — Lists the pin-outs for RS-232C, RS-232D, RS-449, RS-366, and V.35 connectors.

∙Appendix F — Networking Features — Lists the networking features available on each communications system.

∙Appendix G — Robbed-Bit AVD (rbavd) — Explains how to implement rbavd trunks on the Generic 1 communications system.
