Introduction

This Part defines the Cellular Digital Packet Data (CDPD) subnetwork subprofiles. The CDPD Service Provider must select one subprofile from among this set for each real subnetwork interface of a system. These technologies exhibit physical, functional, performance, and cost differences that render some subprofiles more appropriate than others for particular uses.

Other subnetwork technologies (subprofiles) may be used to meet specific deployment requirements. In such cases the CDPD Service Provider must provide proper specification, including conformance requirements, to ensure procurement of an effective product. That is, a product capable of supporting the selected CDPD lower layer subprofiles and interoperating with all systems to be attached to the subnetwork.

The primary reference for this Part is the Industry/Government Open System Specification [IGOSS-1]. The primary reference for the protocols in this Part is the Stable Implementation Agreements for Open Systems Interconnection Protocols [OIW-1].
