The present document provides the User Requirement Specifications (URS) for the enhancements of the TETRA Peripheral Equipment Interface. The existing TETRA PEI standard has been available since 1998. The TETRA Release 2 standard@ incorporating the high-speed data capability (TEDS) has been published. This HSD capability increases the maximum data rate of the TETRA systems from 28@8 kbit/s to over 500 kbit/s@ radically changing the range of data applications available to TETRA users. The TETRA users could@ from now on@ use a range of multimedia applications (with video as a medium) via TEDS channels. One bottleneck to making full use of this new capability is the restrictions imposed by interfacing TETRA Release 2 systems via mobile stations only. Hence@ a standard HSD PEI with a concurrent multimedia capability is essential to enable access to the system from a range of data terminals (such as laptops@ etc.). Peripheral Equipment Interface enhancements translated into terms of: ? PEI physical layer aspects; ? Multimedia capability ; ? QoS negotiation The present document is applicable to the specification of TETRA Release 2 equipment. The user requirements contained in the present document are described mainly in non-technical terms and are based on discussions in TC TETRA WG1.
