35、mative overview of key technical requirements and standards considerations supporting specification of the Console Subsystem Interface (CSSI). Integral to the Project 25 (P25) system architecture, technical specification of the CSSI as an open interface enables functional capabilities on an interope
36、rable and non-proprietary basis. This document is, therefore, primarily intended to facilitate the development of technical standards defining the service and protocol aspects of the CSSI. In addition, the document facilitates development of technical standards concerning definition of measurement m
37、ethods, performance recommendations, conformance tests, and interoperability test methods involving the CSSI. 1.1 Scope The scope of this document is restricted initially to information relevant to the development of standards supporting voice services, and certain supplemental services involving th
38、e CSSI: Services specified in TSB102A Services specified or implied in recent TIA documents that are not currently included in TSB102A Services specified in the recent SOR documents that are not currently included in TSB102A The CSSI is split into Trunking CSSI and Conventional CSSI, with a document
39、 suite for each type of interface. The Conventional CSSI is made up of three “Complexities”: Complexity 1, 2 and 3. Complexity 1 is based upon the Fixed Station Interface control and voice conveyance protocols and the ISSI Transmission Control protocol. CSSI Complexity 1 is defined in the suite of C
40、onventional ISSI documents. CSSI Complexity 1 is IP based utilizing UDP and the Real-time Transport Protocol (RTP). Conventional Complexity 2 uses the Trunking CSSI, described below, and utilizes pre-configured mappings between conventional working IDs and fully qualified IDs and mappings between th
41、e fully qualified IDs fixed stations. The Trunking CSSI is also used for Conventional Complexity 3 which supports full dynamic mobility of conventional SUs. Complexity 3 also needs changes to the CAI to support conventional mobility. Conventional Complexities 2 and 3 are IP based utilizing UDP, RTP
42、and the Session Initiation Protocol (SIP). The Trunking CSSI utilizes the P25 ISSI architecture with slight modifications to some messages for specific console features. The Trunking CSSI is a standard protocol that enables a console subsystem to communicate with Trunking RFSSs and be part of a trun
43、king communications system. The Trunking CSSI is IP based utilizing UDP, RTP and SIP. The Trunking CSSI is also used for Conventional Complexity 2 and Conventional Complexity 3 as described above. TSB-102.BAGA 2 Within this scope, the planned suite of CSSI-related documents consists of the documents
44、 described in Table 1: Table 1 CSSI Document Suite Document Topic Trunking CSSI Documents Conventional CSSI Document Overview This document, to be published as TSB-102.BAGA This document, to be published as TSB-102.BAGA Messages and Procedures Addendum to ISSI M CSSI support for emerging multimedia
45、services; CSSI-related traffic engineering, traffic control, resource reservation, and service level agreements (e.g., based on operational experience); Interconnection of CSSI lower layers in an interoperable manner (e.g., based on operational experience). Network Management Support Future revision
46、s of this document are intended to identify new and revised documents that compose the evolving CSSI standards documentation suite. 1.2 Organization This document is organized as follows. Section 1 provides an introduction. Section 2 provides a list of acronyms and abbreviations. Section 3 provides
47、a list of informative references. Section 4 identifies technical requirements relevant to the standardization of CSSI functional services and protocols for voice services. Section 5 provides technical considerations for standardization of CSSI functional services and protocols for voice services. TS
