This document has been submitted to APCO/NASTD/FED by the Telecommunications Industry Association (TIA), as provided for in a Memorandum of Understanding (MOU) dated December, 1993. That MOU provides t
26、hat APCO/NASTD/FED will devise a Common System Standard for digital public safety communications (the Standard), and that TIA shall provide technical assistance in the development of documentation for the Standard. This document has been developed by TR8.19 (Wireline Interfaces) with inputs from the
27、 APCO Project 25 Interface Committee (APIC), the APIC ISSI Task Group, and TIA Industry members. This document is being published to provide technical information on the emerging digital techniques for Land Mobile Radio Service. This document is an ERRATA to TIA-102.BACA, August 2006, Project 25 Int
28、er-RF Subsystem Interface (ISSI) Messages and Procedures for Voice Services. The ISSI is the interface between Radio Frequency Subsystems (RFSSs) enabling relevant Project 25 user requirements to be satisfied (e.g., as described in the Inter-RF Subsystem Interface Overview (TSB-102.BACC-A). Future r
29、elated standardization efforts are planned to develop new TIA standards defining protocols for an ISSI supporting Project 25-defined conventional voice and data services. In addition, future associated standardization efforts are planned to develop new TIA standards defining compliance tests (e.g.,
30、measurement methods, performance recommendations, and interoperability tests) applicable to equipment implementing the Project 25 ISSI protocols defined in this and future related TIA standards.

By publication of this document no p
32、osition is taken with respect to the validity of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness to grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applican
33、ts desiring to obtain such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified. TIA shall not be responsible for identifying patents for which licenses may be required by this document
34、 or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
