TIA/EIA-732-311 2001 Edition, July 1, 2001 Cellular Digital Packet Data (CDPD) System Specification Lower Layer Subprofiles
More info
Description / Abstract: Introduction
This Part defines the CDPD lower layer subprofiles for services and protocols in the Transport and Network layers. The CDPD Service Provider must select at least one subprofile from among this set for the provision of CDPD lower layer services.
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].
In selecting lower layer subprofiles, the CDPD Service Provider must determine the CDPD communication role(s) a system must support. For the provision of End System services the CDPD Network mandates support of the Internet CLNS subprofile. For the provision of CDPD support service, the CDPD Network mandates support of the ISO COTS-CLNS subprofile. For the support of Intermediate System services CDPD mandates support of the CDPD CLNS-Relay subprofile and the CDPD Mobile CLNS-Relay subprofile.
The complete set of requirements of Transport and Network Layer protocols is a combination of the selected lower layer subprofiles, service interfaces and performance requirements. Particular attention should be paid to the additional functional and interface requirements upon Network Layer protocols (e.g., CLNP, ES-IS, IS-IS, IP, MNLP) dictated by the Subnetwork subprofiles with which they are combined.
